# S3-Compatible TeleUploader Implementation Plan > ⚠️ **LEGACY** — Dokumen historis (2026-07-06). Port & infrastruktur sudah berubah: > produksi kini berjalan di port `4000` (Nix + systemd + Caddy, domain > `upload.asepharyana.my.id`), database via PgBouncer pool `100.121.180.82:6432` > (bukan 5432/localhost). Contoh kode di bawah memakai `localhost:4000` untuk dev. > **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:** Transform TeleUploader into an S3-compatible storage server (Telegram-backed) with a web file manager UI. **Architecture:** An S3 protocol dispatcher at the catch-all route (`$`) intercepts SigV4-authenticated requests and routes them to ~20 S3-compatible endpoints. A JSON v1 API layer wraps the same operations for use by a single-page web file manager served at `/`. Storage remains Telegram (single channel); S3 buckets are virtual entities in PostgreSQL. **Tech Stack:** Bun, TypeScript, PostgreSQL (Drizzle ORM), raw AWS SigV4 (no library), zero external XML deps ## Global Constraints - All new code follows existing codebase style (Bun, TypeScript, Drizzle ORM) - Existing routes (`/api/upload`, `/f/:public_id`, `/file/:public_id/info`, `/health`, `/docs`) must remain unchanged and functional - No external libraries for S3 protocol, auth, or XML handling - All S3 error responses must use correct XML format with AWS error codes - Only one S3 credential pair (`S3_ACCESS_KEY` + `S3_SECRET_KEY`) in env config - Hard-code S3 region as `us-east-1` - Chunked transfer encoding (`aws-chunked`) not supported — return 501 - Presigned GET URLs supported; presigned PUT is optional for v1 - Tests use Bun's built-in test runner and mock patterns (`mock.module()`) - Files in `schema.sql` are raw SQL (not Drizzle migrations); new tables go there - All `/api/v1/*` routes are unprotected (no SigV4); rely on network-level security - Avoid ORM features that don't work with raw `schema.sql` and `postgres` driver — use raw SQL queries or Drizzle's `sql` template tag for complex queries --- ### File Structure #### New files to create: | File | Responsibility | |------|----------------| | `src/utils/s3/auth.ts` | AWS SigV4 signature verification, signing key derivation, canonical request construction | | `src/utils/s3/xml.ts` | S3 XML response builders (all 20+ endpoint templates), XML parser for DeleteObjects body | | `src/db/buckets.ts` | CRUD for `buckets` table: create, list, findByName, delete | | `src/db/multipart.ts` | CRUD for `multipart_uploads` and `multipart_parts` tables: create, list parts, complete, abort, insert part | | `src/db/files-ext.ts` | Extended file queries: findByBucketAndKey, listByPrefix, findActiveByBucket, softDelete, copyObject, listByBucketForUICount | | `src/routes/s3.ts` | S3 protocol dispatcher and all ~20 S3 operation handlers | | `src/routes/web-api.ts` | JSON v1 API endpoints for web UI (buckets, objects, upload, download, copy, delete) | | `src/routes/home.ts` | Serves the file manager HTML at `/` | | `src/home.html` | Web file manager SPA with embedded CSS/JS | | `test/s3-auth.test.ts` | Tests for SigV4 signature verification | | `test/s3-operations.test.ts` | Tests for S3 bucket/object/multipart operations | | `test/web-api.test.ts` | Tests for JSON v1 API endpoints | #### Existing files to modify: | File | Changes | |------|---------| | `schema.sql` | Add `buckets`, `multipart_uploads`, `multipart_parts` tables; add columns to `files` | | `src/env.ts` | Add `S3_ACCESS_KEY`, `S3_SECRET_KEY`, `S3_DEFAULT_REGION` config fields | | `src/index.ts` | Import and register home, web-api, and S3 catch-all routes | | `src/db/files.ts` | No changes needed (existing queries remain); new queries go in `files-ext.ts` | | `.env.example` | Add commented S3 env vars | | `tsconfig.json` | No changes needed | --- ### Task 1: Environment Config + DB Schema **Files:** - Modify: `src/env.ts` - Modify: `schema.sql` - Modify: `.env.example` **Interfaces:** - Consumes: existing `src/env.ts` pattern - Produces: `config.s3AccessKey`, `config.s3SecretKey`, `config.s3DefaultRegion` env fields; new DB tables and columns - [ ] **Step 1: Add S3 env vars to `src/env.ts`** Add to the `AppConfig` interface: ```typescript interface AppConfig { // ... existing fields ... s3AccessKey: string; s3SecretKey: string; s3DefaultRegion: string; } ``` Add to the config object after the `maxRequestBodyBytes` line: ```typescript s3AccessKey: process.env.S3_ACCESS_KEY || 'teleuploader-admin', s3SecretKey: process.env.S3_SECRET_KEY || '', s3DefaultRegion: process.env.S3_DEFAULT_REGION || 'us-east-1', ``` Add S3 vars to the logger.info config block. - [ ] **Step 2: Update `schema.sql` — add new tables and columns** Append after the existing files table: ```sql -- S3-compatible buckets CREATE TABLE IF NOT EXISTS buckets ( id UUID PRIMARY KEY DEFAULT gen_random_uuid(), name VARCHAR(63) UNIQUE NOT NULL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ); -- Extend files table for S3 ALTER TABLE files ADD COLUMN IF NOT EXISTS bucket_id UUID REFERENCES buckets(id); ALTER TABLE files ADD COLUMN IF NOT EXISTS s3_key TEXT; ALTER TABLE files ADD COLUMN IF NOT EXISTS storage_backend VARCHAR DEFAULT 'telegram'; ALTER TABLE files ADD COLUMN IF NOT EXISTS is_deleted BOOLEAN DEFAULT false; ALTER TABLE files ADD COLUMN IF NOT EXISTS multipart_upload_id TEXT; CREATE UNIQUE INDEX IF NOT EXISTS idx_files_bucket_key ON files(bucket_id, s3_key) WHERE is_deleted = false; CREATE INDEX IF NOT EXISTS idx_files_bucket_prefix ON files(bucket_id, s3_key text_pattern_ops); CREATE INDEX IF NOT EXISTS idx_files_s3_key ON files(s3_key); CREATE INDEX IF NOT EXISTS idx_files_bucket_id ON files(bucket_id); -- Multipart upload tracking CREATE TABLE IF NOT EXISTS multipart_uploads ( upload_id VARCHAR PRIMARY KEY, bucket_id UUID NOT NULL REFERENCES buckets(id), s3_key TEXT NOT NULL, initiated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, status VARCHAR DEFAULT 'in_progress', initiated_by TEXT ); CREATE TABLE IF NOT EXISTS multipart_parts ( id SERIAL PRIMARY KEY, upload_id VARCHAR NOT NULL REFERENCES multipart_uploads(upload_id) ON DELETE CASCADE, part_number INT NOT NULL, telegram_file_id VARCHAR NOT NULL, telegram_file_unique_id VARCHAR NOT NULL, storage_message_id BIGINT NOT NULL, size_bytes BIGINT NOT NULL, etag VARCHAR NOT NULL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, UNIQUE(upload_id, part_number) ); CREATE INDEX IF NOT EXISTS idx_multipart_parts_upload ON multipart_parts(upload_id, part_number); CREATE INDEX IF NOT EXISTS idx_multipart_uploads_status ON multipart_uploads(status); ``` - [ ] **Step 3: Update `.env.example`** Append to .env.example: ```env # S3-compatible API credentials # S3_ACCESS_KEY=teleuploader-admin # S3_SECRET_KEY=your-secret-key-here # S3_DEFAULT_REGION=us-east-1 ``` - [ ] **Step 4: Run migration to verify** ```bash cd /mnt/code/TeleUploader && bun run db:migrate ``` Expected: `Database migration completed` logged. No errors. - [ ] **Step 5: Commit** ```bash git add src/env.ts schema.sql .env.example git commit -m "feat: add S3 env config, bucket and multipart DB schema" ``` --- ### Task 2: Database CRUD Layer **Files:** - Create: `src/db/buckets.ts` - Create: `src/db/multipart.ts` - Create: `src/db/files-ext.ts` **Interfaces:** - Consumes: `src/db/index.ts` (existing `db` and `files`), `config` from `src/env.ts` - Produces: Bucket CRUD functions, Multipart CRUD functions, Extended file queries by bucket+key - [ ] **Step 1: Create `src/db/buckets.ts`** ```typescript import { sql } from 'drizzle-orm';

export const handleHome = async (): Promise => { const html = await Bun.file('src/home.html').text(); return new Response(html, { status: 200, headers: { 'content-type': 'text/html; charset=utf-8', }, }); }; ``` - [ ] **Step 2: Create `src/home.html`** This is a comprehensive single-page file manager UI. It must include: - Bucket selector/create/delete - Object listing with folder navigation - Upload via drag & drop or file picker with progress bar - Download and delete actions - Copy link to clipboard - Search/filter - Dark/light mode - Credentials display modal The HTML is too long to reproduce in full here, but the core structure: ```html TeleUploader · S3 File Manager

Select a bucket to get started

Choose a bucket from the dropdown above, or create a new one.

``` - [ ] **Step 3: Register routes in `src/index.ts`** Add imports: ```typescript import { handleHome } from './routes/home'; import { handleWebApiV1 } from './routes/web-api'; import { handleS3Request } from './routes/s3'; import { isS3Request } from './utils/s3/auth'; ``` Add routes to the serve config (after existing routes, before server variable definition): ```typescript serve({ // ... existing routes ... '/': { GET: handleHome, }, // Web API v1 '/api/v1/*': { GET: handleWebApiV1, POST: handleWebApiV1, DELETE: handleWebApiV1, PUT: handleWebApiV1, }, // S3-compatible API catch-all $: async (req: Request) => { // Only handle requests with SigV4 auth header if (isS3Request(Object.fromEntries(req.headers))) { return handleS3Request(req); } return new Response('Not Found', { status: 404 }); }, }) ``` Note: Bun.serve() routes matching priority: literal paths first, then wildcard paths, then `$` catch-all. The `/api/v1/*` pattern is a wildcard route that matches any path starting with `/api/v1/`. For the S3 catch-all, we use `$` which is Bun's catch-all route that fires when no other route matches. Since the S3 catch-all is the last resort, we check the Authorization header to differentiate S3 from true 404s. - [ ] **Step 4: Verify the app still compiles** ```bash cd /mnt/code/TeleUploader && bun build src/index.ts --target=bun --outfile=dist/index.js ``` Expected: Build succeeds with no errors. - [ ] **Step 5: Commit** ```bash git add src/routes/home.ts src/home.html src/index.ts git commit -m "feat: add web file manager UI and S3 catch-all route" ``` --- ### Task 7: Tests **Files:** - Create: `test/s3-auth.test.ts` - Create: `test/s3-operations.test.ts` - Create: `test/web-api.test.ts` - Modify: `package.json` (add test script entries) - [ ] **Step 1: Create `test/s3-auth.test.ts`** ```typescript import { describe, expect, it, beforeAll } from 'bun:test'; describe('S3 Auth (SigV4)', () => { let verifySignature: typeof import('../src/utils/s3/auth').verifySignature; let isS3Request: typeof import('../src/utils/s3/auth').isS3Request; beforeAll(async () => { const auth = await import('../src/utils/s3/auth'); verifySignature = auth.verifySignature; isS3Request = auth.isS3Request; }); it('should detect S3 requests by Authorization header', () => { expect(isS3Request({ authorization: 'AWS4-HMAC-SHA256 Credential=...' })).toBe(true); expect(isS3Request({ authorization: 'Bearer token123' })).toBe(false); expect(isS3Request({})).toBe(false); }); it('should reject missing Authorization header', async () => { const result = await verifySignature('GET', 'http://localhost/', {}, null, 'key', 'secret', 'us-east-1'); expect(result.isValid).toBe(false); }); it('should reject wrong access key', async () => { const headers = { authorization: 'AWS4-HMAC-SHA256 Credential=wrongkey/20260706/us-east-1/s3/aws4_request, SignedHeaders=host, Signature=abc123', 'x-amz-date': '20260706T120000Z', }; const result = await verifySignature('GET', 'http://localhost/', headers, null, 'correctkey', 'secret', 'us-east-1'); expect(result.isValid).toBe(false); expect(result.errorCode).toBe('SignatureDoesNotMatch'); }); it('should accept valid GET ListBuckets request', async () => { // This tests that verification doesn't crash — full SigV4 signature // construction requires exact header matching which is complex. // The real signature verification is tested via integration with S3 clients. const headers = { authorization: 'AWS4-HMAC-SHA256 Credential=testkey/20260706/us-east-1/s3/aws4_request, SignedHeaders=host;x-amz-content-sha256;x-amz-date, Signature=0000000000000000000000000000000000000000000000000000000000000000', 'x-amz-date': '20260706T120000Z', 'x-amz-content-sha256': 'e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855', host: 'localhost', }; const result = await verifySignature('GET', 'http://localhost/', headers, null, 'testkey', 'testsecret', 'us-east-1'); // Expected to not crash (the actual signature won't match with test values) expect(result.isValid).toBe(false); expect(result.errorCode).toBe('SignatureDoesNotMatch'); }); }); ``` - [ ] **Step 2: Create `test/s3-operations.test.ts`** Tests for S3 bucket and object operations. Because the S3 endpoints depend on Telegram (which is mocked), we test in isolation: ```typescript import { afterAll, beforeAll, beforeEach, describe, expect, it, mock } from 'bun:test'; // Mock DB and Telegram const mockDbExecute = mock(() => Promise.resolve({ rows: [], rowCount: 0 }));
