This is unofficial SDK to use LINE Login inside the node.js based application on top of express framework.
Go to LINE developers console and create your channel for LINE Login. You need to configure callback URL in this site.
$ npm install --save line-login express express-session
"use strict";
const app = require('express')();
const line_login = require("line-login");
const session = require("express-session");
const session_options = {
secret: process.env.LINE_LOGIN_CHANNEL_SECRET,
resave: false,
saveUninitialized: false
}
app.use(session(session_options));
const login = new line_login({
channel_id: process.env.LINE_LOGIN_CHANNEL_ID,
channel_secret: process.env.LINE_LOGIN_CHANNEL_SECRET,
callback_url: process.env.LINE_LOGIN_CALLBACK_URL,
scope: "openid profile",
prompt: "consent",
bot_prompt: "normal"
});
app.listen(process.env.PORT || 5000, () => {
console.log(`server is listening to ${process.env.PORT || 5000}...`);
});
// Specify the path you want to start authorization.
app.use("/", login.auth());
// Specify the path you want to wait for the callback from LINE authorization endpoint.
app.use("/callback", login.callback(
(req, res, next, token_response) => {
// Success callback
res.json(token_response);
},
(req, res, next, error) => {
// Failure callback
res.status(400).json(error);
}
