| description | File uploads in Serverpod — upload descriptions, verification, storage backends (database, S3, GCP). Use when implementing file uploads or cloud storage. |
Flow: server issues upload description → client uploads → server verifies. Default storage is the database; use S3 or GCP for production.
Future<String?> getUploadDescription(Session session, String path) async {
return await session.storage.createDirectFileUploadDescription(
storageId: 'public',
path: path,
);
}
Restrict paths in production (derive from user/session).
Future<bool> verifyUpload(Session session, String path) async {
return await session.storage.verifyDirectFileUpload(
storageId: 'public', path: path);
}
Always verify after client upload when using S3 or GCP.
var desc = await client.myEndpoint.getUploadDescription('profile/$userId/avatar.png');
if (desc != null) {
var uploader = FileUploader(desc);
await uploader.upload(byteDataOrStream);
await client.myEndpoint.verifyUpload('profile/$userId/avatar.png');
}
Use Stream for large files. Paths: no leading slash, S3/GCP compatible.
session.storage.fileExists(storageId: 'public', path: path)session.storage.getPublicUrl(storageId: 'public', path: path) (public storage only)session.storage.retrieveFile(storageId: 'public', path: path)public and private storages. Fine for dev.serverpod_cloud_storage_gcp, set HMAC keys in passwords.yaml or env. Register: pod.addCloudStorage(GoogleCloudStorage(...)).serverpod_cloud_storage_s3, set AWS keys. Register: pod.addCloudStorage(S3CloudStorage(...)).Use storageId: 'public' or 'private' when replacing defaults.
Add Serverpod authentication — serverpod_auth_idp packages, initializeAuthServices, identity providers (Email, Google, Apple, etc.), Flutter sign-in UI, migrations. Use when adding authentication or a new social sign-in to a Serverpod project.
Serverpod caching — local and Redis caches, cache keys, lifetime, CacheMissHandler. Use when caching data, optimizing queries, or working with session.caches.
Serverpod CLI — serverpod create, generate, create-migration, and other commands. Use when generating code, creating migrations, or creating projects/modules.
Configure Serverpod — YAML config, environment variables, passwords, run modes, generator.yaml, TLS. Use when setting up environments, API/database/Redis settings, or managing secrets.
Serverpod ORM with PostgreSQL — CRUD, filters, sorting, pagination, relations, migrations, transactions, raw SQL. Use when querying the database, writing migrations, or working with relations. Also include serverpod-models skill if you need to change models.
Define Serverpod endpoints, use Session, pass parameters, and call from client. Use when creating RPC endpoints, working with Session, or client code generation.
