This PR is the first of a series introducing direct client-to-storage uploads. It adds the server-side endpoints and driver support only — it is non-breaking and nothing consumes the new flow yet. Follow-up PRs will migrate the frontend upload paths, add a stale-pending-file cleanup cron, and cap the legacy buffered resolvers. ## What it does **New upload flow (initiate → PUT → confirm):** - `createFileUpload(filename, size, fileFolder, fieldMetadataId?)` validates the request (folder allowlist: `FilesField`/`Workflow`, max size, extension-derived mime type), creates the file record in a new `PENDING` status, and returns an upload target: - **S3 with presign enabled** → a presigned PUT URL with `Content-Type`/`Content-Length` pinned in the signature, so the client uploads straight to the bucket; - **local storage, or S3 without presign** → a token-authenticated streaming endpoint on the server (`PUT /file-upload/:id?token=…`, new `FILE_UPLOAD` JWT type) that pipes the request body to the storage driver with constant memory usage and a declared-size cap. - `completeFileUpload(fileId)` verifies the bytes actually landed in storage (HEAD + size match against the declared size) and flips the record to `UPLOADED`. Idempotent. **Pending lifecycle safety:** - New `status` column on `core.file` (`PENDING`/`UPLOADED`, default `UPLOADED` so all existing rows and the legacy upload path are unaffected) + fast instance command. - Files are refused by the serving endpoints and by FILES-field sync while `PENDING`. **Driver support (both drivers):** - `getPresignedUploadUrl` (S3: presigned PUT; local: `null` → server-endpoint fallback) - `writeFileStream` (local: `fs` pipeline with the existing symlink/containment hardening, partial-file cleanup on error; S3: `@aws-sdk/lib-storage` `Upload` for bounded-memory streaming) - `getFileMetadata` (HEAD/stat for confirm-time verification) ## Tests - `file-upload.service.spec.ts`: initiate validation (folder allowlist, size), presigned vs fallback target, confirm verification (missing object, size mismatch, happy path, idempotency) - `local.driver.spec.ts`: `writeFileStream` (content, symlink rejection, partial-file cleanup on stream error), `getFileMetadata` - `s3.driver.spec.ts`: `getPresignedUploadUrl` (disabled → null, PUT command with signed content-type/content-length) - `direct-file-upload.integration-spec.ts`: full end-to-end flow against the local driver (initiate → PUT → complete → download), plus error paths (complete without upload, oversized PUT → 413, invalid token → 403, unsupported folder, size above max) ## Notes for reviewers - The upload-size ceiling for direct uploads is `settings.storage.maxDirectUploadFileSize` (1GB), separate from the 10MB `maxFileSize` used for pictures. - Since content can't be sniffed before it reaches storage, the mime type is derived from the file extension (with the existing `TWENTY_MIME_POLICY` override) and unknown extensions fall back to `application/octet-stream`; the serving path already forces `Content-Disposition: attachment` for anything not on the inline-safe allowlist. - Self-hosters using S3 presign will need a bucket CORS policy allowing `PUT` from the frontend origin (config variable description updated). https://claude.ai/code/session_015UH8KWmsB9zdYaog8MFG1d --- _Generated by [Claude Code](https://claude.ai/code/session_015UH8KWmsB9zdYaog8MFG1d)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22449?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
