## Introduction
In aim to reduce and optimize the number of twenty-front build we do
during our cd process and allow twenty-front build promotion
### Build time
**Nothing is baked.** The `build/` directory is a clean, env-agnostic
artifact. `index.html` contains the empty placeholder:
```html
<script id="twenty-env-config">
window._env_ = {
// This will be overwritten
};
</script>
```
The JS bundles contain no hardcoded server URL.
---
### Deploy mode 1: Frontend served by the backend (Docker / NestJS)
1. Container starts, NestJS boots in `main.ts`
2. `generateFrontConfig()` runs, reads `process.env.SERVER_URL`
3. Rewrites `dist/front/index.html`, replacing the placeholder with:
```html
<script id="twenty-env-config">
window._env_ = {
REACT_APP_SERVER_BASE_URL: "https://api.example.com"
};
</script>
```
4. NestJS serves the static `dist/front/` directory
5. Browser loads `index.html`, `window._env_` is set before the app JS
executes
6. `src/config/index.ts` reads `window._env_.REACT_APP_SERVER_BASE_URL`
and uses it
---
### Deploy mode 2: Frontend served standalone (CDN / nginx / static
server)
1. Take the `build/` artifact as-is
2. Before serving, run at deploy time:
```bash
REACT_APP_SERVER_BASE_URL=https://api.example.com sh
./scripts/inject-runtime-env.sh
```
3. This does the same `sed` replacement on `build/index.html`
4. Serve the `build/` directory with your static server of choice
5. Same resolution in the browser:
`window._env_.REACT_APP_SERVER_BASE_URL` is picked up by
`src/config/index.ts`
---
### Fallback: no injection at all
If neither mechanism runs (e.g. local dev with `vite dev`),
`window._env_.REACT_APP_SERVER_BASE_URL` is `undefined`, and
`getDefaultUrl()` kicks in:
- **Localhost**: returns `http://localhost:3000`
- **Non-localhost**: returns same-origin (`window.location.origin`)
## Summary
This PR upgrades Apollo Client from v3.10.0 to v4 and refactors error
handling patterns across the codebase to use a new centralized
`useSnackBarOnQueryError` hook.
## Key Changes
- **Dependency Update**: Upgraded `@apollo/client` from `^3.10.0` to
`^3.11.0` in root package.json
- **New Hook**: Added `useSnackBarOnQueryError` hook for centralized
Apollo query error handling with snack bar notifications
- **Error Handling Refactor**: Updated 100+ files to use the new error
handling pattern:
- Removed direct `ApolloError` imports where no longer needed
- Replaced manual error handling logic with `useSnackBarOnQueryError`
hook
- Simplified error handling in hooks and components across multiple
modules
- **GraphQL Codegen**: Updated codegen configuration files to work with
Apollo Client v3.11.0
- **Type Definitions**: Added TypeScript declaration file for
`apollo-upload-client` module
- **Test Updates**: Updated test files to reflect new error handling
patterns
## Notable Implementation Details
- The new `useSnackBarOnQueryError` hook provides a consistent way to
handle Apollo query errors with automatic snack bar notifications
- Changes span across multiple feature areas: auth, object records,
settings, workflows, billing, and more
- All changes maintain backward compatibility while improving code
maintainability and reducing duplication
- Jest configuration updated to work with the new Apollo Client version

Moves system-level operations (auth, billing, admin) to use the
/metadata endpoint instead of /graphql.
This cleans up the endpoint separation so /graphql is purely for core
objects (Company, People, etc.) and /metadata handles all system
operations.
Part of prep work for webhook/API key core migration.
