The Firebase team made it clear, we want a more robust system that can be manipulated locally and can be robust enough and more developer friendly, so they created the Bolt language, and according to the Firebase team the language is:
"The Bolt language is meant to be used as a convenient frontend to the existing Firebase JSON-based rules language."
To use it locally, we need to install a NodeJS utility on our development machine, fire up your terminal/cmd, and type the following command:
~> npm install -g firebase-bolt
This command will go and install the Firebase Bolt compiler locally, now go ahead and create a new file and name it whatever you want, but don't forget to give it the .bolt extension.
Now in order to compile this file simply type the following command in your terminal/cmd:
~> firebase-bolt...
