## Summary - When `STORAGE_S3_PRESIGNED_URL_BASE` is configured, the file controller returns a **302 redirect** to a presigned S3 URL instead of proxying every byte through the server. This eliminates server bandwidth and CPU overhead for S3-backed deployments. - For local storage or S3 without a public endpoint, behavior is unchanged (stream + pipe with security headers). - Added `getPresignedUrl` to the `StorageDriver` interface (required method returning `string | null`), with implementations in S3Driver (uses a separate presign client with the public endpoint), LocalDriver (returns `null`), and ValidatedStorageDriver (path traversal protection + delegation). - Added a unified `getFileResponseById` method in `FileService` that performs a single DB lookup and returns either a redirect URL or a stream, avoiding double lookups. - Extracted `getContentDisposition` from the header util so both the proxy path and presigned URL path share the same inline/attachment allowlist. - Added MinIO service to `docker-compose.dev.yml` (optional `s3` profile) for local S3 testing. - Documented S3 presigned URL setup, CORS, and `nosniff` requirements in the self-hosting docs. ## Test plan - [x] All 63 unit tests pass across 5 test suites (util, S3 driver, validated driver, file storage service, controller) - [x] `npx nx typecheck twenty-server` passes - [ ] Manual E2E test with MinIO: `docker compose --profile s3 up -d`, configure S3 env vars, verify `curl -I` returns 302 with `Location` header pointing to MinIO - [ ] Verify local storage (no `STORAGE_S3_PRESIGNED_URL_BASE`) still streams files with 200 + security headers - [ ] Verify public assets endpoint still proxies (no redirect) Made with [Cursor](https://cursor.com)

📝 Editing Content
Adding/Editing Pages
-
Edit MDX files in the appropriate directory:
user-guide/- User documentationdevelopers/- Developer documentationtwenty-ui/- Component documentation
-
Update
navigation/base-structure.jsonif you need to change the tab/group hierarchy or add/remove pages. This file stays in the repo and is not uploaded to Crowdin. -
Keep the translation template (
navigation/navigation.template.json) in sync by runningyarn docs:generate-navigation-templateafter editing the base structure. This template is the only file that should be pushed to Crowdin. -
For each translated locale pulled from Crowdin, ensure a
packages/twenty-docs/l/<language>/navigation.jsonfile exists. These files contain labels only; page slugs always come from the base structure. -
Run
yarn docs:generateto rebuilddocs.jsonfrom the base structure + translated labels.
MDX Format
