File storage

Add a file field

1. Open a table in Database.
2. Add a file field.
3. Set the allowed file types, maximum size, and how many files it can hold.
4. Mark it protected if only signed-in users should download it.

Upload with JavaScript

const post = await rb.from("posts").create({
  title: "Hello",
  cover: fileInput.files[0],
});

Upload with Dart

import "package:http/http.dart" as http;

await rb.from("posts").create(
  {"title": "Hello"},
  files: [http.MultipartFile.fromString("attachment", "content", filename: "note.txt")],
);

Show and protect files

rb.files.url(record, record.avatar, { thumb: "100x100" });

// protected files need a short-lived token
const token = await rb.files.token();
rb.files.url(record, record.contract, { token });

Your own object storage

Plans that include it can store files in your own S3-compatible bucket instead of Project storage. Set it up in Project settings.

Production guidance

• Limit file types and sizes.
• Keep private files protected.
• Delete files you no longer need and watch storage usage.
• Include files in your backup plan.
