# Introduction
Next handling mimetype integrity check and checksum integrity check for
s3 storage type
Always expecting a trailing end slash when deleting a folder etc
## Application
Uninstalling an application now deletes all its related files
## File storage service
Making a distincton between folder path and file path
## Validation Pipeline
Every file operation in `FileStorageService.buildOnStoragePath` runs
through `validateResourcePath`, which chains three validators in order:
**1. `validateSafeRelativePath`** -- rejects path traversal attacks
| Input | Result | Error |
|---|---|---|
| `../../../etc/passwd` | Rejected | `Resource path must not contain
path traversal (..)` |
| `/etc/passwd` | Rejected | `Resource path must be relative, not
absolute` |
| `file\0.txt` | Rejected | `Resource path contains null bytes` |
| `..\\..\\etc\\passwd` | Rejected | `Resource path must not contain
backslashes` |
| _(empty)_ | Rejected | `Resource path must not be empty` |
**2. `validateFilenameIntegrity`** -- enforces safe characters, length
limits, extension required
| Input | Result | Error |
|---|---|---|
| `my folder/file.mjs` | Rejected | `A path segment contains invalid
characters...` |
| `Makefile` | Rejected | `Filename must have an extension` |
| `aaa...(256 chars).mjs` | Rejected | `A path segment exceeds the
maximum length of 255 characters` |
| `a/b/.../file.mjs` (1025+ chars) | Rejected | `Resource path exceeds
maximum length of 1024 characters` |
| `src/handlers/index.mjs` | Accepted | -- |
| `my-app/my_file.tsx` | Accepted | -- |
| `v1.0/module.config.mjs` | Accepted | -- |
Allowed characters per segment: `a-z`, `A-Z`, `0-9`, `.`, `-`, `_`
**3. `validateResourceExtension`** -- checks extension against the
`FileFolder` allowlist
| Input | FileFolder | Result | Error |
|---|---|---|---|
| `handler.js` | `BuiltLogicFunction` | Rejected | `Invalid file
extension. Allowed extensions: .mjs` |
| `card.tsx` | `BuiltFrontComponent` | Rejected | `Invalid file
extension. Allowed extensions: .mjs` |
| `script.js` | `PublicAsset` | Rejected | `Invalid file extension.
Allowed extensions: .png, .jpg, ...` |
| `index.mjs` | `BuiltLogicFunction` | Accepted | -- |
| `app.tsx` | `Source` | Accepted | -- |
| `photo.png` | `CorePicture` | Accepted | -- (unconfigured folder,
passes through) |
## Consumers
- **`FileStorageService`** -- calls `validateResourcePath`, throws
`FileStorageException` on failure (last-resort defense)
- **Resolver (`uploadApplicationFile`)** -- calls
`validateResourcePath`, throws `ApplicationException` on failure
(user-facing)
- **Flat validators** -- call `validateResourcePath`, push the error to
`validationResult.errors` (non-throwing, collects all errors)
All error messages are translated via Lingui `t` and returned in a
discriminated union `{ isValid: true } | { isValid: false, error: string
}`, letting each consumer decide how to handle failures.

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.
