GraphQL data and files with access rules
Define a schema and query it right away. Per-schema and per-field rules decide who can read and write.
Schemas, rules and files in one service
GraphQL from your schema
Add a schema in the visual editor or as a JSON file and publish it. Blocks generates query, insert, insertMany, update, updateMany, delete and deleteMany, with where filters and AND/OR conditions.
Row- and column-level rules
Make a schema or a single field public, open to any signed-in user, or limited by rules on the user's ID, email, roles or permissions and the record's own fields.
Validation on every write
Attach regex, length, range and comparison checks to fields. Describe a pattern in plain language and Blocks writes the regex for you.
Files with folders, versions and sharing
Upload through pre-signed URLs, keep every version, move and copy files without duplicating the bytes, share with View, Download, Edit or Manage access, and restore from the trash.
Managed or your own MongoDB
Use the database Blocks runs for each environment, or point the project at your own MongoDB Atlas cluster.
Playground and data browser
Try queries with introspection in the Data Playground, and browse records as a table or JSON with filters and sorting.
Define it once, query it from your app
Keep schemas and rules in your repo as JSON, sync them with the CLI, and call them from your app with the SDK.

Pull the schemas

blocks data syncpushes schema and rule changes and reloads the gateway. Run it with--dry-runfirst to see the plan.Read and write from your app
data.collection()gives you list, get, create, update and delete for a schema. Usedata.graphql()for joins and custom query shapes.

Questions about Data
Which databases does Data support?
MongoDB. Each environment gets a database that Blocks runs, or you can connect your own MongoDB Atlas cluster with a connection URL and database name.
How do access rules work?
Each schema and each field has a policy: public, any signed-in user, or custom rules that compare the user's ID, email, roles or permissions with fields on the record. The gateway applies them to every query and mutation.
Where are files stored?
On Azure Blob Storage by default. You can add Amazon S3, S3-compatible storage such as MinIO, or an SFTP server as named storage configurations and choose one per upload.
Do schema changes need a redeploy?
No. Publish the schema in the console or run blocks data sync, and the gateway reloads with the new fields.
