# Introduction
Allow a consumer call the commands programmatically instead of passing
by the exec
To do so extract from the command definition all the core logic, created
a new error api that allow keeping same error logs granularity than
before
## Usage
```ts
import { authLogin, appUninstall, functionExecute } from 'twenty-sdk/cli';
const result = await authLogin({
apiKey: 'my-key',
apiUrl: 'https://my-twenty.com',
});
if (!result.success) {
throw new Error(result.error);
}
```
## `app:build`
Introduced a new command that will allow building the whole project
without any watch setup
- Build and validate manifest
- Get or create app
- Synchronize manifest with twenty-sdk stub and no typecheck
- generate client
- Run typecheck
- Synchronize manifest again
