Sandbox settings

Your code runs in sandbox processes : containers built for the account, with the npm packages you choose. This page shapes them.
Page Utility → Sandbox Settings
Sandbox count How many sandbox processes run at once. Each one runs the process initializers.
Dependencies The npm packages available to every custom API, hook, event, scheduler and utility class, with their versions and sub dependencies.
Docker file The image of the sandbox : a base file, an extended base and the final file, each editable and resettable, with the build logs and the final package.json.
Allowed origins The web origins allowed to call the APIs from a browser : a name and a domain per row. Empty : every origin.
Auto restart Restart the sandboxes every N seconds, for code which leaks.

Dependencies

  1. Add a package with its name and version. The build installs it and lists its sub dependencies.
  2. import * as dayjs from 'dayjs' in your code, like any npm package.

  3. A package which needs a system library goes in the Docker file : install Python, ImageMagick or a client library there.

  4. Private registries are not supported.

  5. The schema generation runs once, without your packages : keep computations out of it.

Allowed origins

  • With one origin listed, a browser request from any other origin is refused with 403 before anything runs. Add the origins of your web apps, and keep the list empty while developing locally if you prefer.
