@adntro/google-cloud-auth

Google Cloud auth utilitities (get token from functions, local, etc.)

It makes easy to get a bearer token to use from local to invoked authorized endpoints (Cloud Functions, Cloud Run, etc.), and also to get that token to invoke a secured resource from another resorce.

Getting started

Install as a dependency

npm i -S @adntro/google-cloud-auth

In local environment you must have installed gcloud sdk (https://cloud.google.com/sdk/docs/install)
From a function, the service account which executes the code should have permission to invoke the remote function

Usage

const { getIdToken } = require('@adntro/google-cloud-auth');

async function invokeEndpoint(url, data) {
    const token = await getIdToken(url);
    return fetch(url, {
        method: 'POST',
        body: JSON.stringify(data),
        headers: {
            'Content-Type': 'application/json',
            'Accept': 'application/json',
            'Authorization': 'Bearer ' + token  // <-- The idToken
        }
    });
}
