Fixes https://github.com/twentyhq/core-team-issues/issues/1956
**Problem**
Within an app, the `.yarn/releases/` folder contains executable Yarn
binaries that run when executing any yarn command (`.yarnrc` file
indicates yarn path to be `.yarn/releases/yarn-4.9.2.cjs `.)
This is a supply chain attack vector: a malicious actor could submit a
PR with a compromised `yarn-4.9.2.cjs binary`, which would execute
arbitrary code on developers' machines or CI systems.
**Fix**
Actually, thanks to Corepack, we don't need to store and execute this
binary.
Corepack can be seen as the manager of a package manager: in
`package.json` we indicate a packageManager version like
`"packageManager": "yarn@4.9.2"`, and when executing `yarn` Corepack
will securely fetch the verified version from npm, avoiding the risk of
executing a compromised binary committed to the repository. This was
already in our app's package.json template but we were not using it!
We can now
- remove the folder containing the binary from our app template
base-application (that is scaffolded when creating an app through cli),
`.yarn/releases/`, and remove `yarnPath: .yarn/releases/yarn-4.9.2.cjs`
from its .yarnrc
- remove them from the community apps that were already published in the
repo
- add .yarn to gitignore
**Tested**
This has been tested and works for app created in the repo, outside the
repo, and existing apps in the repo
## Summary
Moves the custom ESLint rules from `tools/eslint-rules` to
`packages/twenty-eslint-rules` for better organization within the
monorepo packages structure.
## Changes
- Move `eslint-rules` from `tools/` to `packages/twenty-eslint-rules`
- Use `loadWorkspaceRules` from `@nx/eslint-plugin` to load custom rules
- Update all ESLint configs to use the `twenty/` rule prefix instead of
`@nx/workspace-`
- Update `project.json`, `jest.config.mjs` with new paths
- Update `package.json` workspaces and `nx.json` cache inputs
- Update Dockerfile reference
## Technical Details
The custom ESLint rules are now loaded using Nx's `loadWorkspaceRules`
utility which:
- Handles TypeScript transpilation automatically
- Allows loading workspace rules from any directory
- Provides a cleaner approach than the previous `@nx/workspace-`
convention
## Testing
- Verified all 17 custom ESLint rules load correctly from the new
location
- Verified linting works on dependent packages (twenty-front,
twenty-server, etc.)
## Summary
This PR reduces clutter at the repository root to improve navigation on
GitHub. The README is now visible much sooner when browsing the repo.
## Changes
### Deleted from root
- `nx` wrapper script → use `npx nx` instead
- `render.yaml` → no longer used
- `jest.preset.js` → inlined `@nx/jest/preset` directly in each
package's jest.config
- `.prettierrc` → moved config to `package.json`
- `.prettierignore` → patterns already covered by `.gitignore`
### Moved/Consolidated
| From | To |
|------|-----|
| `Makefile` | `packages/twenty-docker/Makefile` (merged) |
| `crowdin-app.yml` | `.github/crowdin-app.yml` |
| `crowdin-docs.yml` | `.github/crowdin-docs.yml` |
| `.vale.ini` | `.github/vale.ini` |
| `tools/eslint-rules/` | `packages/twenty-eslint-rules/` |
| `eslint.config.react.mjs` |
`packages/twenty-front/eslint.config.react.mjs` |
## Result
Root items reduced from ~32 to ~22 (folders + files).
## Files updated
- GitHub workflow files updated to reference new crowdin config paths
- Jest configs updated to use `@nx/jest/preset` directly
- ESLint configs updated with new import paths
- `nx.json` updated with new paths
- `package.json` now includes prettier config and updated workspace
paths
- Dockerfile updated with new eslint-rules path
