This section contains information for integrating and configuring the Node.js Snapshot Debugger agent in different environments. Full configuration information for the agent can be found at Node.js Agent Documentation

See samples/node-js for working examples of installing and configuring the Node.js agent across different Google Cloud environments.

It's also possible to run things outside of a Google Cloud environment, such as locally. Here are some notes for doing so, which involves generating a service account key so the agents are able to read/write from the Firebase RTDB backend.

1. Navigate to your project in the Firebase console service account page. Replace PROJECT_ID with your project’s ID.

   https://console.firebase.google.com/project/PROJECT_ID/settings/serviceaccounts/adminsdk
   

2. Click Generate new private key and save the key locally.

1. Use npm to install the package:

   npm install --save @google-cloud/debug-agent
   

2. Configure and enable the agent at the top of your app's main script or entry point (but after @google/cloud-trace if you are also using it).

   require('@google-cloud/debug-agent').start({
     useFirebase: true,
     firebaseKeyPath: 'PATH-TO-KEY-FILE',
     // Specify this if you are the Spark billing plan and are using the
     // default RTDB instance.
     // firebaseDbUrl: 'https://RTDB-NAME-default-rtdb.firebaseio.com',
     serviceContext: {
       service: 'SERVICE',
       version: 'VERSION',
     }
   });
   

   Where:

   • PATH-TO-KEY-FILE is the path to your Firebase private key.
   • RTDB-NAME is the name of your Firebase database.
   • SERVICE is a name for your app, such as MyApp, Backend, or Frontend.
   • VERSION is a version, such as v1.0, build_147, or v20170714.
