# Cloudflare Workers Deployment Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Make the app deployable to Cloudflare Workers with OpenNext, D1-backed data, private R2 exports, explicit local/online separation, and API-key protection.
**Architecture:** Keep the existing local Node path intact while adding a Cloudflare path selected through a small runtime boundary. Route handlers use async repository and export-store interfaces; local implementation uses the existing SQLite/filesystem behavior, while Cloudflare implementation uses `getCloudflareContext().env.DB` and `env.EXPORT_BUCKET`.
**Tech Stack:** Next.js 16, TypeScript, OpenNext Cloudflare adapter, Wrangler, Cloudflare D1, Cloudflare R2, Vitest.
---
## File Structure
- Modify `package.json`: add Cloudflare dependencies and explicit scripts.
- Modify `.gitignore`: ignore `.open-next`, `.wrangler`, `.dev.vars`, and generated Cloudflare type files if needed.
- Modify `next.config.ts`: initialize OpenNext dev integration.
- Create `open-next.config.ts`: OpenNext Cloudflare adapter config.
- Create `wrangler.jsonc`: Worker, assets, D1, R2, env, and observability config.
- Create `migrations/0001_initial_schema.sql`: D1 initial schema copied from the current SQLite schema.
- Create `src/lib/runtime/cloudflare.ts`: typed access to Cloudflare bindings.
- Create `src/lib/api/auth.ts`: API key guard shared by route handlers.
- Create `src/lib/db/repository.ts`: async repository interface and runtime selector.
- Create `src/lib/db/sqlite-repository.ts`: async wrapper around existing SQLite functions for local runtime.
- Create `src/lib/db/d1-repository.ts`: D1 implementation.
- Create `src/lib/workflow/export-store.ts`: local and R2 export-store implementations.
- Modify API routes under `src/app/api/jobs/**/route.ts`: use auth, async repository, and export store.
- Modify tests under `src/app/api/__tests__`, `src/lib/db/__tests__`, and `src/lib/workflow/__tests__`.
- Modify `README.md` and `.env.example`: document local vs staging vs production deployment.
## Task 1: Add Cloudflare Build Configuration
**Files:**
- Modify: `package.json`
- Modify: `.gitignore`
- Modify: `next.config.ts`
- Create: `open-next.config.ts`
- Create: `wrangler.jsonc`
- Create: `public/_headers`
- Create: `.dev.vars.example`
- [ ] **Step 1: Install dependencies**
Run:
```bash
npm install @opennextjs/cloudflare@latest
npm install --save-dev wrangler@latest @cloudflare/workers-types@latest
```
Expected: `package.json` and `package-lock.json` include the new packages.
- [ ] **Step 2: Update `package.json` scripts**
Edit the scripts block to include these entries while preserving existing scripts:
```json
{
"test": "vitest run",
"dev": "next dev",
"build": "next build",
"start": "next start",
"lint": "next lint",
"test:watch": "vitest",
"build:worker": "opennextjs-cloudflare build",
"preview:worker": "opennextjs-cloudflare build && opennextjs-cloudflare preview",
"deploy:worker:staging": "opennextjs-cloudflare build && opennextjs-cloudflare deploy --env staging",
"deploy:worker:production": "opennextjs-cloudflare build && opennextjs-cloudflare deploy --env production",
"cf-typegen": "wrangler types --env-interface CloudflareEnv cloudflare-env.d.ts",
"d1:migrate:local": "wrangler d1 migrations apply geo-agent-article-optimizer-local --local",
"d1:migrate:staging": "wrangler d1 migrations apply geo-agent-article-optimizer-staging --env staging --remote",
"d1:migrate:production": "wrangler d1 migrations apply geo-agent-article-optimizer-production --env production --remote"
}
```
- [ ] **Step 3: Add ignored generated/local files**
Append these entries to `.gitignore`:
```gitignore
.open-next
.wrangler
.dev.vars
cloudflare-env.d.ts
```
- [ ] **Step 4: Add OpenNext config**
Create `open-next.config.ts`:
```typescript
import { defineCloudflareConfig } from "@opennextjs/cloudflare";
export default defineCloudflareConfig({});
```
- [ ] **Step 5: Initialize OpenNext dev support in `next.config.ts`**
Replace `next.config.ts` with:
```typescript
import type { NextConfig } from "next";
import { initOpenNextCloudflareForDev } from "@opennextjs/cloudflare";
const nextConfig: NextConfig = {};
export default nextConfig;
initOpenNextCloudflareForDev();
```
- [ ] **Step 6: Add `wrangler.jsonc`**
Create `wrangler.jsonc` with local bindings only. Add staging and production entries after creating the real Cloudflare resources in Task 9, so no fake remote database IDs are committed.
```jsonc
{
"$schema": "node_modules/wrangler/config-schema.json",
"main": ".open-next/worker.js",
"name": "geo-agent-article-optimizer",
"compatibility_date": "2026-06-16",
"compatibility_flags": ["nodejs_compat", "global_fetch_strictly_public"],
"assets": {
"directory": ".open-next/assets",
"binding": "ASSETS"
},
"observability": {
"enabled": true,
"head_sampling_rate": 0.1
},
"services": [
{
"binding": "WORKER_SELF_REFERENCE",
"service": "geo-agent-article-optimizer"
}
],
"vars": {
"APP_RUNTIME": "cloudflare",
"LLM_PROVIDER": "deepseek",
"DEEPSEEK_BASE_URL": "https://api.deepseek.com",
"DEEPSEEK_MODEL": "deepseek-v4-pro",
"DEEPSEEK_THINKING": "disabled",
"OPENAI_MODEL": "gpt-4.1-mini"
},
"d1_databases": [
{
"binding": "DB",
"database_name": "geo-agent-article-optimizer-local",
"database_id": "00000000-0000-0000-0000-000000000001",
"migrations_dir": "migrations"
}
],
"r2_buckets": [
{
"binding": "EXPORT_BUCKET",
"bucket_name": "geo-agent-article-optimizer-local"
}
],
"env": {}
}
```
- [ ] **Step 7: Add static asset caching headers**
Create `public/_headers`:
```text
/_next/static/*
Cache-Control: public,max-age=31536000,immutable
```
- [ ] **Step 8: Add local Worker env example**
Create `.dev.vars.example`:
```text
NEXTJS_ENV=development
API_ACCESS_KEY=local-worker-dev-key
DEEPSEEK_API_KEY=
OPENAI_API_KEY=
```
- [ ] **Step 9: Generate Cloudflare binding types**
Run:
```bash
npm run cf-typegen
```
Expected: command exits 0. The generated `cloudflare-env.d.ts` remains ignored.
## Task 2: Add D1 Migration
**Files:**
- Create: `migrations/0001_initial_schema.sql`
- [ ] **Step 1: Create initial migration**
Create `migrations/0001_initial_schema.sql`:
```sql
CREATE TABLE IF NOT EXISTS brand_templates (
id TEXT PRIMARY KEY,
brand_name TEXT NOT NULL,
company_full_name TEXT NOT NULL,
company_short_names TEXT NOT NULL,
product_names TEXT NOT NULL,
target_industries TEXT NOT NULL,
target_audience TEXT NOT NULL,
verified_claims TEXT NOT NULL,
forbidden_claims TEXT NOT NULL,
tone_rules TEXT NOT NULL,
created_at TEXT NOT NULL,
updated_at TEXT NOT NULL
);
CREATE TABLE IF NOT EXISTS article_jobs (
id TEXT PRIMARY KEY,
brand_template_id TEXT,
source_title TEXT NOT NULL,
source_body TEXT NOT NULL,
image_inputs TEXT NOT NULL,
publish_platform TEXT NOT NULL,
user_instructions TEXT NOT NULL,
status TEXT NOT NULL,
export_paths TEXT NOT NULL,
created_at TEXT NOT NULL,
updated_at TEXT NOT NULL,
FOREIGN KEY (brand_template_id) REFERENCES brand_templates(id)
);
CREATE TABLE IF NOT EXISTS fact_cards (
job_id TEXT PRIMARY KEY,
source TEXT NOT NULL,
fact_card TEXT NOT NULL,
confirmed_by_user INTEGER NOT NULL,
created_at TEXT NOT NULL,
updated_at TEXT NOT NULL,
FOREIGN KEY (job_id) REFERENCES article_jobs(id) ON DELETE CASCADE
);
CREATE TABLE IF NOT EXISTS optimized_articles (
job_id TEXT NOT NULL,
revision INTEGER NOT NULL,
article TEXT NOT NULL,
created_at TEXT NOT NULL,
PRIMARY KEY (job_id, revision),
FOREIGN KEY (job_id) REFERENCES article_jobs(id) ON DELETE CASCADE
);
CREATE TABLE IF NOT EXISTS qa_reports (
job_id TEXT NOT NULL,
revision INTEGER NOT NULL,
report TEXT NOT NULL,
created_at TEXT NOT NULL,
PRIMARY KEY (job_id, revision),
FOREIGN KEY (job_id, revision)
REFERENCES optimized_articles(job_id, revision) ON DELETE CASCADE
);
CREATE INDEX IF NOT EXISTS idx_article_jobs_updated_at
ON article_jobs(updated_at);
```
- [ ] **Step 2: Apply migration locally**
Run:
```bash
npm run d1:migrate:local
```
Expected: Wrangler applies `0001_initial_schema.sql` to the local D1 database. Runtime code must not call `CREATE TABLE`, `DROP TABLE`, or table-clearing SQL for the Cloudflare path.
## Task 3: Introduce API Key Guard
**Files:**
- Create: `src/lib/api/auth.ts`
- Test: `src/lib/api/__tests__/auth.test.ts`
- [ ] **Step 1: Write failing auth tests**
Create `src/lib/api/__tests__/auth.test.ts`:
```typescript
import { describe, expect, test } from "vitest";
import { requireApiAccess } from "../auth";
describe("requireApiAccess", () => {
test("allows local test requests when auth is explicitly disabled", () => {
const request = new Request("http://localhost/api/jobs");
const result = requireApiAccess(request, {
apiAccessKey: undefined,
authDisabled: true,
});
expect(result.ok).toBe(true);
});
test("rejects requests when the configured key is missing", () => {
const request = new Request("http://localhost/api/jobs");
const result = requireApiAccess(request, {
apiAccessKey: "secret",
authDisabled: false,
});
expect(result.ok).toBe(false);
if (!result.ok) {
expect(result.response.status).toBe(401);
}
});
test("rejects requests with the wrong key", () => {
const request = new Request("http://localhost/api/jobs", {
headers: { "x-api-key": "wrong" },
});
const result = requireApiAccess(request, {
apiAccessKey: "secret",
authDisabled: false,
});
expect(result.ok).toBe(false);
});
test("allows requests with the correct key", () => {
const request = new Request("http://localhost/api/jobs", {
headers: { "x-api-key": "secret" },
});
const result = requireApiAccess(request, {
apiAccessKey: "secret",
authDisabled: false,
});
expect(result.ok).toBe(true);
});
});
```
- [ ] **Step 2: Run auth tests and verify RED**
Run:
```bash
npm test -- src/lib/api/__tests__/auth.test.ts
```
Expected: FAIL because `src/lib/api/auth.ts` does not exist.
- [ ] **Step 3: Implement auth guard**
Create `src/lib/api/auth.ts`:
```typescript
import { NextResponse } from "next/server";
interface ApiAccessOptions {
apiAccessKey?: string;
authDisabled?: boolean;
}
type ApiAccessResult =
| { ok: true }
| { ok: false; response: NextResponse<{ error: string }> };
export function requireApiAccess(
request: Request,
options: ApiAccessOptions = {
apiAccessKey: process.env.API_ACCESS_KEY,
authDisabled: process.env.API_AUTH_DISABLED === "true",
},
): ApiAccessResult {
if (options.authDisabled) {
return { ok: true };
}
if (!options.apiAccessKey) {
return {
ok: false,
response: NextResponse.json(
{ error: "API access key is not configured" },
{ status: 401 },
),
};
}
const provided = request.headers.get("x-api-key");
if (provided !== options.apiAccessKey) {
return {
ok: false,
response: NextResponse.json({ error: "Unauthorized" }, { status: 401 }),
};
}
return { ok: true };
}
```
- [ ] **Step 4: Run auth tests and verify GREEN**
Run:
```bash
npm test -- src/lib/api/__tests__/auth.test.ts
```
Expected: PASS.
## Task 4: Add Repository Boundary And Local Adapter
**Files:**
- Create: `src/lib/db/repository.ts`
- Create: `src/lib/db/sqlite-repository.ts`
- Modify: `src/lib/db/repositories.ts`
- Test: `src/lib/db/__tests__/repository.test.ts`
- [ ] **Step 1: Write failing repository adapter test**
Create `src/lib/db/__tests__/repository.test.ts`:
```typescript
import { mkdtempSync, rmSync } from "node:fs";
import { join } from "node:path";
import { tmpdir } from "node:os";
import { afterEach, beforeEach, describe, expect, test } from "vitest";
import { createSqliteRepository } from "../sqlite-repository";
describe("createSqliteRepository", () => {
let tempDir: string;
let dbPath: string;
beforeEach(() => {
tempDir = mkdtempSync(join(tmpdir(), "geo-repository-"));
dbPath = join(tempDir, "app.db");
});
afterEach(() => {
rmSync(tempDir, { recursive: true, force: true });
});
test("creates and reads an article job through the async repository interface", async () => {
const repository = createSqliteRepository(dbPath);
const job = await repository.createArticleJob({
source_title: "Title",
source_body: "Body",
image_inputs: [],
publish_platform: "official_site",
user_instructions: "",
});
await expect(repository.getArticleJob(job.id)).resolves.toMatchObject({
id: job.id,
source_title: "Title",
export_paths: {},
});
});
});
```
- [ ] **Step 2: Run repository adapter test and verify RED**
Run:
```bash
npm test -- src/lib/db/__tests__/repository.test.ts
```
Expected: FAIL because `sqlite-repository` does not exist.
- [ ] **Step 3: Create async repository interface**
Create `src/lib/db/repository.ts`:
```typescript
import type { ConfirmedFactCard, OptimizedArticle, QaReport } from "../domain/types";
import type {
ArticleJob,
BrandTemplate,
NewArticleJob,
NewBrandTemplate,
} from "./repositories";
export interface AppRepository {
createBrandTemplate(input: NewBrandTemplate): Promise<BrandTemplate>;
listBrandTemplates(): Promise<BrandTemplate[]>;
getBrandTemplate(id: string): Promise<BrandTemplate | null>;
createArticleJob(input: NewArticleJob): Promise<ArticleJob>;
getArticleJob(id: string): Promise<ArticleJob | null>;
updateArticleJob(
id: string,
changes: Partial<Pick<ArticleJob, "brand_template_id" | "status" | "export_paths">>,
): Promise<ArticleJob | null>;
saveFactCard(jobId: string, factCard: ConfirmedFactCard): Promise<{ job_id: string } & ConfirmedFactCard>;
getFactCard(jobId: string): Promise<({ job_id: string } & ConfirmedFactCard) | null>;
saveOptimizedArticle(jobId: string, article: OptimizedArticle): Promise<OptimizedArticle>;
getLatestOptimizedArticle(jobId: string): Promise<OptimizedArticle | null>;
saveQaReport(jobId: string, revision: number, report: QaReport): Promise<QaReport>;
getQaReport(jobId: string, revision: number): Promise<QaReport | null>;
}
```
- [ ] **Step 4: Create local SQLite adapter**
Create `src/lib/db/sqlite-repository.ts`:
```typescript
import type { ConfirmedFactCard, OptimizedArticle, QaReport } from "../domain/types";
import type { AppRepository } from "./repository";
import {
createArticleJob,
createBrandTemplate,
getArticleJob,
getBrandTemplate,
getFactCard,
getLatestOptimizedArticle,
getQaReport,
listBrandTemplates,
saveFactCard,
saveOptimizedArticle,
saveQaReport,
updateArticleJob,
type ArticleJob,
type NewArticleJob,
type NewBrandTemplate,
} from "./repositories";
export function createSqliteRepository(dbPath?: string): AppRepository {
return {
createBrandTemplate(input: NewBrandTemplate) {
return Promise.resolve(createBrandTemplate(dbPath, input));
},
listBrandTemplates() {
return Promise.resolve(listBrandTemplates(dbPath));
},
getBrandTemplate(id: string) {
return Promise.resolve(getBrandTemplate(dbPath, id));
},
createArticleJob(input: NewArticleJob) {
return Promise.resolve(createArticleJob(dbPath, input));
},
getArticleJob(id: string) {
return Promise.resolve(getArticleJob(dbPath, id));
},
updateArticleJob(
id: string,
changes: Partial<Pick<ArticleJob, "brand_template_id" | "status" | "export_paths">>,
) {
return Promise.resolve(updateArticleJob(dbPath, id, changes));
},
saveFactCard(jobId: string, factCard: ConfirmedFactCard) {
return Promise.resolve(saveFactCard(dbPath, jobId, factCard));
},
getFactCard(jobId: string) {
return Promise.resolve(getFactCard(dbPath, jobId));
},
saveOptimizedArticle(jobId: string, article: OptimizedArticle) {
return Promise.resolve(saveOptimizedArticle(dbPath, jobId, article));
},
getLatestOptimizedArticle(jobId: string) {
return Promise.resolve(getLatestOptimizedArticle(dbPath, jobId));
},
saveQaReport(jobId: string, revision: number, report: QaReport) {
return Promise.resolve(saveQaReport(dbPath, jobId, revision, report));
},
getQaReport(jobId: string, revision: number) {
return Promise.resolve(getQaReport(dbPath, jobId, revision));
},
};
}
```
- [ ] **Step 5: Run repository adapter test and verify GREEN**
Run:
```bash
npm test -- src/lib/db/__tests__/repository.test.ts
```
Expected: PASS.
## Task 5: Add D1 Repository
**Files:**
- Create: `src/lib/db/d1-repository.ts`
- Test: `src/lib/db/__tests__/d1-repository.test.ts`
- [ ] **Step 1: Write D1 repository tests with a fake D1 database**
Create `src/lib/db/__tests__/d1-repository.test.ts` with a fake prepared-statement database that records SQL and returns controlled rows:
```typescript
import { describe, expect, test, vi } from "vitest";
import { createD1Repository } from "../d1-repository";
describe("createD1Repository", () => {
test("creates an article job using D1 prepare and bind", async () => {
const run = vi.fn().mockResolvedValue({ success: true });
const bind = vi.fn().mockReturnValue({ run });
const prepare = vi.fn().mockReturnValue({ bind });
const db = { prepare } as unknown as D1Database;
const repository = createD1Repository(db);
const job = await repository.createArticleJob({
source_title: "Title",
source_body: "Body",
image_inputs: [],
publish_platform: "official_site",
user_instructions: "",
});
expect(job.id).toMatch(/^job_/);
expect(prepare).toHaveBeenCalledWith(expect.stringContaining("insert into article_jobs"));
expect(bind).toHaveBeenCalledWith(
job.id,
null,
"Title",
"Body",
"[]",
"official_site",
"",
"draft",
"{}",
job.created_at,
job.updated_at,
);
});
test("parses article job JSON fields returned from D1", async () => {
const first = vi.fn().mockResolvedValue({
id: "job_123",
brand_template_id: null,
source_title: "Title",
source_body: "Body",

status: "draft",
export_paths: "{}",
created_at: "2026-06-16T00:00:00.000Z",
updated_at: "2026-06-16T00:00:00.000Z",
});
const bind = vi.fn().mockReturnValue({ first });
const prepare = vi.fn().mockReturnValue({ bind });
const db = { prepare } as unknown as D1Database;
const repository = createD1Repository(db);
await expect(repository.getArticleJob("job_123")).resolves.toMatchObject({
id: "job_123",
image_inputs: [],
export_paths: {},
});
});
});
```
- [ ] **Step 2: Run D1 repository tests and verify RED**
Run:
```bash
npm test -- src/lib/db/__tests__/d1-repository.test.ts
```
Expected: FAIL because `d1-repository` does not exist.
- [ ] **Step 3: Implement D1 repository**
Create `src/lib/db/d1-repository.ts` with the full async D1 implementation below. Use `prepare(...).bind(...).run()`, `first<T>()`, and `all<T>()`. Do not include schema creation or destructive SQL in this file.
The implementation must include these helpers:
```typescript
function nowIso() {
return new Date().toISOString();
}
function serialize(value: unknown) {
return JSON.stringify(value);
}
function parseJson<T>(value: string): T {
return JSON.parse(value) as T;
}
```
The implementation must expose:
```typescript
export function createD1Repository(db: D1Database): AppRepository {
return {
async createBrandTemplate(input) {
const createdAt = nowIso();
const template = {
id: `brand_${nanoid(10)}`,

}
```
- [ ] **Step 4: Run D1 repository tests and verify GREEN**
Run:
```bash
npm test -- src/lib/db/__tests__/d1-repository.test.ts

Expected: PASS.
## Task 6: Add Runtime Repository Selection
**Files:**
- Create: `src/lib/runtime/cloudflare.ts`
- Modify: `src/lib/db/repository.ts`
- Test: `src/lib/db/__tests__/repository-selection.test.ts`
- [ ] **Step 1: Write runtime selection tests**
Create `src/lib/db/__tests__/repository-selection.test.ts`:
```typescript
import { describe, expect, test } from "vitest";
import { getRepositoryFromRuntime } from "../repository";
describe("getRepositoryFromRuntime", () => {
test("returns local repository when APP_RUNTIME is not cloudflare", () => {
const repository = getRepositoryFromRuntime({
appRuntime: "local",
dbPath: ":memory:",
});
expect(repository).toBeDefined();
});
test("throws clearly for cloudflare runtime without D1 binding", () => {
expect(() =>
getRepositoryFromRuntime({
appRuntime: "cloudflare",
cloudflareEnv: {},
}),
).toThrow("Cloudflare D1 binding DB is required");
});
});
```
- [ ] **Step 2: Run runtime selection tests and verify RED**
Run:
```bash
npm test -- src/lib/db/__tests__/repository-selection.test.ts
```
Expected: FAIL because `getRepositoryFromRuntime` does not exist.
- [ ] **Step 3: Implement runtime access helper**
Create `src/lib/runtime/cloudflare.ts`:
```typescript
import { getCloudflareContext } from "@opennextjs/cloudflare";
export interface AppCloudflareEnv {
DB?: D1Database;
EXPORT_BUCKET?: R2Bucket;
API_ACCESS_KEY?: string;
}
export function getAppCloudflareEnv(): AppCloudflareEnv | null {
if (process.env.APP_RUNTIME !== "cloudflare") {
return null;
}
return getCloudflareContext().env as AppCloudflareEnv;
}
```
- [ ] **Step 4: Implement repository selection**
Append to `src/lib/db/repository.ts`:
```typescript
import { getAppCloudflareEnv, type AppCloudflareEnv } from "../runtime/cloudflare";
import { createD1Repository } from "./d1-repository";
import { createSqliteRepository } from "./sqlite-repository";
interface RuntimeRepositoryOptions {
appRuntime?: string;
dbPath?: string;
cloudflareEnv?: AppCloudflareEnv;
}
export function getRepositoryFromRuntime(options: RuntimeRepositoryOptions = {}): AppRepository {
const appRuntime = options.appRuntime ?? process.env.APP_RUNTIME;
if (appRuntime === "cloudflare") {
const env = options.cloudflareEnv ?? getAppCloudflareEnv();
if (!env?.DB) {
throw new Error("Cloudflare D1 binding DB is required");
}
return createD1Repository(env.DB);
}
return createSqliteRepository(options.dbPath);
}
```
- [ ] **Step 5: Run runtime selection tests and verify GREEN**
Run:
```bash
npm test -- src/lib/db/__tests__/repository-selection.test.ts
```
Expected: PASS.
## Task 7: Add Local And R2 Export Stores
**Files:**
- Modify: `src/lib/workflow/exporter.ts`
- Create: `src/lib/workflow/export-store.ts`
- Test: `src/lib/workflow/__tests__/export-store.test.ts`
- [ ] **Step 1: Write export-store tests**
Create `src/lib/workflow/__tests__/export-store.test.ts`:
```typescript
import { mkdtempSync, rmSync } from "node:fs";
import { join } from "node:path";
import { tmpdir } from "node:os";
import { afterEach, beforeEach, describe, expect, test, vi } from "vitest";
import type { OptimizedArticle, QaReport } from "../../domain/types";
import { createLocalExportStore, createR2ExportStore } from "../export-store";
const article: OptimizedArticle = {
title: "Example",
summary: "Summary",
body_markdown: "Body",
image_suggestions: [],
requires_user_confirmation: [],
revision: 1,
};
const report: QaReport = {
overall_status: "pass",
checks: [],
blocked_reasons: [],
};
describe("export stores", () => {
let tempDir: string;
beforeEach(() => {
tempDir = mkdtempSync(join(tmpdir(), "geo-export-store-"));
});
afterEach(() => {
rmSync(tempDir, { recursive: true, force: true });
});
test("local store writes and reads exports", async () => {
const store = createLocalExportStore(tempDir);
const paths = await store.writeJobExports({
jobId: "job_123",
article,
qaReport: report,
});
expect(paths.markdown).toContain("optimized.md");
const file = await store.readJobExport("job_123", "optimized.md");
expect(await file?.text()).toContain("# Example");
});
test("R2 store writes private export objects through binding", async () => {
const put = vi.fn().mockResolvedValue(undefined);
const bucket = { put } as unknown as R2Bucket;
const store = createR2ExportStore(bucket);
const paths = await store.writeJobExports({
jobId: "job_123",
article,
qaReport: report,
});
expect(paths.markdown).toBe("r2://exports/job_123/optimized.md");
expect(put).toHaveBeenCalledWith(
"exports/job_123/optimized.md",
expect.any(String),
expect.objectContaining({
httpMetadata: { contentType: "text/markdown; charset=utf-8" },
}),
);
});
});
```
- [ ] **Step 2: Run export-store tests and verify RED**
Run:
```bash
npm test -- src/lib/workflow/__tests__/export-store.test.ts
```
Expected: FAIL because `export-store` does not exist.
- [ ] **Step 3: Implement export-store boundary**
Create `src/lib/workflow/export-store.ts`:
```typescript
import { existsSync, mkdirSync, readFileSync, writeFileSync } from "node:fs";
import { join } from "node:path";
import { getAppDataDir } from "../db/connection";
import type { OptimizedArticle, QaReport } from "../domain/types";
import {
renderOptimizedDocx,
renderOptimizedMarkdown,
renderQaReportJson,
} from "./exporter";
const CONTENT_TYPES: Record<string, string> = {
"optimized.md": "text/markdown; charset=utf-8",
"optimized.docx":
"application/vnd.openxmlformats-officedocument.wordprocessingml.document",
"qa_report.json": "application/json; charset=utf-8",
};
export interface WriteJobExportsInput {
jobId: string;
article: OptimizedArticle;
qaReport: QaReport;
}
export interface ExportFile {
body: BodyInit;
contentType: string;
}
export interface ExportStore {
writeJobExports(input: WriteJobExportsInput): Promise<Record<string, string>>;
readJobExport(jobId: string, fileName: string): Promise<Response | null>;
}
export function createLocalExportStore(dataDir = getAppDataDir()): ExportStore {
return {
async writeJobExports({ jobId, article, qaReport }) {
const exportDir = join(dataDir, "exports", jobId);
mkdirSync(exportDir, { recursive: true });
const markdown = join(exportDir, "optimized.md");
const docx = join(exportDir, "optimized.docx");
const qaJson = join(exportDir, "qa_report.json");
writeFileSync(markdown, renderOptimizedMarkdown(article), "utf8");
writeFileSync(qaJson, renderQaReportJson(qaReport), "utf8");
writeFileSync(docx, await renderOptimizedDocx(article));
return { markdown, docx, qaJson };
},
async readJobExport(jobId, fileName) {
const contentType = CONTENT_TYPES[fileName];
if (!contentType) return null;
const path = join(dataDir, "exports", jobId, fileName);
if (!existsSync(path)) return null;
return new Response(readFileSync(path), {
headers: {
"content-type": contentType,
"content-disposition": `attachment; filename="${fileName}"`,
},
});
},
};
}
export function createR2ExportStore(bucket: R2Bucket): ExportStore {
return {
async writeJobExports({ jobId, article, qaReport }) {
const prefix = `exports/${jobId}`;
const markdownKey = `${prefix}/optimized.md`;
const docxKey = `${prefix}/optimized.docx`;
const qaJsonKey = `${prefix}/qa_report.json`;
await bucket.put(markdownKey, renderOptimizedMarkdown(article), {
httpMetadata: { contentType: CONTENT_TYPES["optimized.md"] },
});
await bucket.put(qaJsonKey, renderQaReportJson(qaReport), {
httpMetadata: { contentType: CONTENT_TYPES["qa_report.json"] },
});
await bucket.put(docxKey, await renderOptimizedDocx(article), {
httpMetadata: { contentType: CONTENT_TYPES["optimized.docx"] },
});
return {
markdown: `r2://${markdownKey}`,
docx: `r2://${docxKey}`,
qaJson: `r2://${qaJsonKey}`,
};
},
async readJobExport(jobId, fileName) {
const contentType = CONTENT_TYPES[fileName];
if (!contentType) return null;
const object = await bucket.get(`exports/${jobId}/${fileName}`);
if (!object) return null;
return new Response(object.body, {
headers: {
"content-type": object.httpMetadata?.contentType ?? contentType,
"content-disposition": `attachment; filename="${fileName}"`,
},
});
},
};
}
```
- [ ] **Step 4: Run export-store tests and verify GREEN**
Run:
```bash
npm test -- src/lib/workflow/__tests__/export-store.test.ts
```
Expected: PASS.
## Task 8: Wire Routes To Auth, Repository, And Export Store
**Files:**
- Modify: `src/app/api/jobs/route.ts`
- Modify: `src/app/api/jobs/[jobId]/confirm-fact-card/route.ts`
- Modify: `src/app/api/jobs/[jobId]/optimize/route.ts`
- Modify: `src/app/api/jobs/[jobId]/exports/[fileName]/route.ts`
- Test: `src/app/api/__tests__/jobs.test.ts`
- [ ] **Step 1: Update API tests for API key enforcement**
In `src/app/api/__tests__/jobs.test.ts`, add tests that call the route without `x-api-key` and expect `401`, then call with `x-api-key` and expect the existing behavior. In test setup set:
```typescript
const originalApiKey = process.env.API_ACCESS_KEY;
const originalAuthDisabled = process.env.API_AUTH_DISABLED;
beforeEach(() => {
process.env.API_ACCESS_KEY = "test-key";
process.env.API_AUTH_DISABLED = "false";
});
afterEach(() => {
process.env.API_ACCESS_KEY = originalApiKey;
process.env.API_AUTH_DISABLED = originalAuthDisabled;
});
```
For existing successful route calls, construct requests with:
```typescript
headers: { "x-api-key": "test-key" }
```
- [ ] **Step 2: Run API tests and verify RED**
Run:
```bash
npm test -- src/app/api/__tests__/jobs.test.ts
```
Expected: FAIL because routes do not call `requireApiAccess` yet.
- [ ] **Step 3: Update route handlers**
In every API route, add this pattern at the start of each handler:
```typescript
const access = requireApiAccess(request);
if (!access.ok) {
return access.response;
}
```
Use `_request` only in handlers that do not need auth; after this change every API route needs `request`.
Replace direct repository calls with:
```typescript
const repository = getRepositoryFromRuntime();
```
Then await calls:
```typescript
const job = await repository.getArticleJob(jobId);
```
In optimize route, replace `writeJobExports` with runtime export store:
```typescript
const exportStore = getExportStoreFromRuntime();
const exportPaths =
qaReport.overall_status === "fail"
? {}
: await exportStore.writeJobExports({
jobId,
article: optimizedArticle,
qaReport,
});
```
In export download route, replace filesystem reads with:
```typescript
const exportStore = getExportStoreFromRuntime();
const response = await exportStore.readJobExport(jobId, fileName);
if (!response) {
return NextResponse.json({ error: "Export file not found" }, { status: 404 });
}
return response;
```
- [ ] **Step 4: Add export-store runtime selector**
Append this function to `src/lib/workflow/export-store.ts`:
```typescript
import { getAppCloudflareEnv } from "../runtime/cloudflare";
export function getExportStoreFromRuntime(): ExportStore {
if (process.env.APP_RUNTIME === "cloudflare") {
const env = getAppCloudflareEnv();
if (!env?.EXPORT_BUCKET) {
throw new Error("Cloudflare R2 binding EXPORT_BUCKET is required");
}
return createR2ExportStore(env.EXPORT_BUCKET);
}
return createLocalExportStore();
}
```
- [ ] **Step 5: Run API tests and verify GREEN**
Run:
```bash
npm test -- src/app/api/__tests__/jobs.test.ts
```
Expected: PASS.
## Task 9: Document Manual Cloudflare Resource And Deployment Flow
**Files:**
- Modify: `README.md`
- Modify: `.env.example`
- Modify: `wrangler.jsonc`
- [ ] **Step 1: Update `.env.example`**
Replace the environment example with local-only values:
```text
LLM_PROVIDER=deepseek
DEEPSEEK_API_KEY=
DEEPSEEK_BASE_URL=https://api.deepseek.com
DEEPSEEK_MODEL=deepseek-v4-pro
DEEPSEEK_THINKING=disabled
OPENAI_API_KEY=
OPENAI_MODEL=gpt-4.1-mini
APP_DATA_DIR=./data
API_ACCESS_KEY=local-dev-key
API_AUTH_DISABLED=false
```
- [ ] **Step 2: Update README deployment section**
Add a Cloudflare section with this content. Use four-space indentation for nested command examples so the README renders cleanly:
## Cloudflare Workers Deployment
Cloudflare deployment is manual. Pushing to Git does not deploy or hot-update
the production Worker.
Local development:
npm run dev
Cloudflare preview:
cp .dev.vars.example .dev.vars
npm run d1:migrate:local
npm run preview:worker
Create private staging resources:
npx wrangler d1 create geo-agent-article-optimizer-staging
npx wrangler r2 bucket create geo-agent-article-optimizer-staging
Create private production resources:
npx wrangler d1 create geo-agent-article-optimizer-production
npx wrangler r2 bucket create geo-agent-article-optimizer-production
After D1 creation, copy the returned database IDs into the matching
`wrangler.jsonc` environment entries. Keep R2 buckets private; do not add
public bucket domains.
Set secrets:
npx wrangler secret put API_ACCESS_KEY --env staging
npx wrangler secret put DEEPSEEK_API_KEY --env staging
npx wrangler secret put API_ACCESS_KEY --env production
npx wrangler secret put DEEPSEEK_API_KEY --env production
Migration order:
npm run d1:migrate:local
npm run d1:migrate:staging
npm run deploy:worker:staging
npm run d1:migrate:production
npm run deploy:worker:production
All API requests require:
x-api-key: <API_ACCESS_KEY>
- [ ] **Step 3: Verify docs mention no runtime schema mutation**
Run:
```bash
rg -n "migrations|automatic|API_ACCESS_KEY|private|hot-update|hot update|x-api-key" README.md docs/superpowers/specs/2026-06-16-cloudflare-workers-deployment-design.md
```
Expected: output includes D1 migrations, private R2, manual deployment, and API key language.
- [ ] **Step 4: Leave remote env blocks out until real resource IDs exist**
If the executor cannot create Cloudflare resources in this session, keep `env` as `{}` in `wrangler.jsonc`. Do not commit fake staging or production `database_id` values. The README documents the exact commands for creating resources and adding remote env blocks after Wrangler returns real database IDs.
Expected: `wrangler.jsonc` contains no fake staging or production database IDs.
## Task 10: Full Verification
**Files:**
- All modified files
- [ ] **Step 1: Run focused tests**
Run:
```bash
npm test -- src/lib/api/__tests__/auth.test.ts src/lib/db/__tests__/repository.test.ts src/lib/db/__tests__/repository-selection.test.ts src/lib/db/__tests__/d1-repository.test.ts src/lib/workflow/__tests__/export-store.test.ts src/app/api/__tests__/jobs.test.ts
```
Expected: PASS.
- [ ] **Step 2: Run full test suite**
Run:
```bash
npm test
```
Expected: PASS.
- [ ] **Step 3: Run regular Next.js build**
Run:
```bash
npm run build
```
Expected: exit 0.
- [ ] **Step 4: Run Worker build**
Run:
```bash
npm run build:worker
```
Expected: exit 0 and `.open-next/worker.js` exists.
- [ ] **Step 5: Run Wrangler dry run**
Run:
```bash
npx wrangler deploy --dry-run
```
Expected: Wrangler validates the Worker bundle. If staging/production IDs are not configured yet, dry-run top-level local config still validates.
- [ ] **Step 6: Inspect for forbidden runtime schema changes**
Run:
```bash
rg -n "CREATE TABLE|DROP TABLE|DELETE FROM|initializeSchema" src wrangler.jsonc migrations
```
Expected: `CREATE TABLE` only appears in `migrations/0001_initial_schema.sql` and local SQLite test/setup code. No Cloudflare runtime file creates, drops, or clears tables.
- [ ] **Step 7: Commit implementation**
Run:
```bash
git add .gitignore .dev.vars.example README.md next.config.ts open-next.config.ts package.json package-lock.json public/_headers wrangler.jsonc migrations src docs/superpowers
git commit -m "feat: add cloudflare workers deployment path"
```
Expected: commit succeeds without staging unrelated `.DS_Store`.
