LINE Messaging API for Node.js

About LINE Messaging API

Please refer to the official API documents for details.

Installation

$ npm install linebot --save

Usage

var linebot = require('linebot');

var bot = linebot({
	channelId: CHANNEL_ID,
	channelSecret: CHANNEL_SECRET,
	channelAccessToken: CHANNEL_ACCESS_TOKEN
});

bot.on('message', function (event) {
	event.reply(event.message.text).then(function (data) {
		// success
	}).catch(function (error) {
		// error
	});
});

bot.listen('/linewebhook', 3000);

Using with your own Express.js server

const app = express();
const linebotParser = bot.parser();
app.post('/linewebhook', linebotParser);
app.listen(3000);

API

linebot(config)

Create LineBot instance with specified configuration.

var bot = linebot({
	channelId: CHANNEL_ID,
	channelSecret: CHANNEL_SECRET,
	channelAccessToken: CHANNEL_ACCESS_TOKEN,
	verify: true // Verify 'X-Line-Signature' header (default=true)
});

LineBot.listen(webHookPath, port, callback)

Start built-in http server on the specified port, and accept POST request callback on the specified webHookPath.

This method is provided for convenience. You can write you own server and use verify and parse methods to process webhook events. See examples/echo-express-long.js for example.

LineBot.parser()

Create Express.js middleware to parse the request.

The parser assumes that the request body has never been parsed by any body parser before, so it must be placed BEFORE any generic body parser e.g. app.use(bodyParser.json());

LineBot.verify(rawBody, signature)

Verify X-Line-Signature header.

LineBot.parse(body)

Process incoming webhook request, and raise an event.

LineBot.on(eventType, eventHandler)

Raised when a Webhook event is received.

bot.on('message',  function (event) { });
bot.on('follow',   function (event) { });
bot.on('unfollow', function (event) { });
bot.on('join',     function (event) { });
bot.on('leave',    function (event) { });
bot.on('postback', function (event) { });
bot.on('beacon',   function (event) { });

LineBot.push(to, message)

Send push message.

to is a userId, or an array of userId. A userId can be saved from event.source.userId when added as a friend (follow event), or during the chat (message event).

message can be a string, an array of string, a Send message object, or an array of Send message objects.

LineBot.multicast(to, message)

Send push message to multiple users (Max: 150 users). This is more efficient than push as it will make api call only once.

to is an array of userId.

message can be a string, an array of string, a Send message object, or an array of Send message objects.

LineBot.leaveGroup(groupId)

Leave a group.

LineBot.leaveRoom(roomId)

Leave a room.

Event.reply(message)

Respond to the event.

message can be a string, an array of string, a Send message object, or an array of Send message objects.

Return a Promise object from node-fetch module.

This is a shorthand for LineBot.reply(event.replyToken, message);

event.reply('Hello, world').then(function (data) {
	// success
}).catch(function (error) {
	// error
});

event.reply({ type: 'text', text: 'Hello, world' });

event.reply([
	{ type: 'text', text: 'Hello, world 1' },
	{ type: 'text', text: 'Hello, world 2' }
]);

event.reply({
