Bolt Compiler

Bolt is an experimental security and rules compiler for Firebase Realtime Database (not for Firebase Cloud Storage). It is currently in beta. The language definition is converging, but not yet finalized. We welcome experimentation, but ask that you hand-verify the resulting JSON output before using with production applications.

Otherwise, we'd love to have feedback from early adopters. You can email questions to firebase-talk@googlegroups.com using "Bolt" in the subject line, or post bugs on our Issue Tracker.

Using the Bolt Compiler

You can easily install the bolt compiler using npm:

$ npm install --global firebase-bolt

Execute the Bolt compiler from the command line:

$ firebase-bolt rules.bolt

Will create a rules.json which you can then upload via the Firebase Web Console or the Firebase command line:

$ firebase deploy

The firebase command line tool version 2 will also compile your Bolt file directly if you have firebase-bolt installed and you use the .bolt file extension in the rules property of your firebase.json configuration file.
