LIFF v2 starter app with Firebase

This repo shows you how to connect Firebase Custom Auth with LINE LIFF.

Deploy method

We use Firebase Hosting to host the LIFF application, obviously.

Prerequisite

You need to create a Firebase project with:

1. firebase functions:config:set liff.id=YOUR_LIFF_ID line.channel_id=YOUR_CHANNEL_ID
2. Enable IAM API
3. Because of Cloud Function's restriction, you need to enter billing info to enable external network access for LINE's APIs

Deployment

Use following commands:

firebase init
firebase deploy

Credit and License

This project is derived from LINE's official line-liff-v2-starter project but with major rewrite to demo Firebase integration.
