Debugging Access Token Issuer

This sample demonstrates a Firebase Cloud Function that issues debugging access tokens to authenticated and authorized users.

The directory structure looks like this:

server/
 |
 +- firebase.json  # Describes properties of the project
 |
 +- genkey.sh      # Optional script to generate token signing
                   # key and certificates with a self-signed CA
 |
 + package.json    # npm package file
 |
 +- functions/     # Directory containing the function code
      |
      +- api_config.SAMPLE.json # A sample configuration
      |
      +- .eslintrc.json  # Rules for JavaScript linting
      |
      +- package.json  # npm package file
      |
      +- index.js      # main source file
      |
      +- node_modules/ # directory where the dependencies (declared in
                       # package.json) are installed

Running the Samples

• Setup Firebase Cloud Functions. See Step 1-3 of the guide at https://firebase.google.com/docs/functions/get-started.
• Prepare the token signing key and certificate. The key MUST be a RSA key with at least 2048 bits. The certificate MUST contain at least one Subject Alternative Name (SAN). Use genkey.sh if signing the certificate with a self-signed CA.
• Configure the token issuer in a config file. See api_config.SAMPLE.json for an example. The config file contains secret information; do NOT commit it in git.
• Deploy the config file by running firebase functions:config:set api_config="$(cat YOUR_CONFIG.json)".
• Deploy the Cloud Function. See the instructions at https://firebase.google.com/docs/functions/manage-functions.
