Using the Amazon template, this shows how to valdiate a Firebase token (https://firebase.google.com/docs/auth/admin/verify-id-tokens) with NodeJs and a Lambda function. This can then be used in API Gateway to validate API usage.
- Clone this repository.
- Run npm install from the project root.
- Zip the following:
- node_modules
- package.json
- server.js
In AWS, create a new Lambda function.
- Set the following environment variables under the Advanced section of the Code tab.
- firebaseUrl - https://[appname].firebaseio.com
- firebasePrivateKey - from property 'private_key' of the private key json file
- firebaseClientEmail - from property 'client_email' of the private key json file
- firebaseProjectId - from property 'project_id' of the private key json file
- See the Admin Setup from Firebase docs (https://firebase.google.com/docs/admin/setup) on how to setup admin access.
- Upload the zip file of code on the Code tab; once uploaded to you can edit the code via the inline Lambda editor.
- Configure the test input.
{
"authorizationToken": "",
"methodArn": "arn:...../*/GET/",
"type": "TOKEN"
}The authorization token can be fetched from via the following snippet:
firebase.auth().currentUser.getToken(/* forceRefresh */ true).then(function(idToken) {
// Send token to your backend via HTTPS
// ...
}).catch(function(error) {
// Handle error
});See https://firebase.google.com/docs/auth/web/google-signin#redirect-mode for more info.
