Installation

npm i --save messaging-api-line

or

yarn add messaging-api-line

Usage

Initialize

const { LineClient } = require('messaging-api-line');

// get accessToken and channelSecret from LINE developers website
const client = new LineClient({
  accessToken: ACCESS_TOKEN,
  channelSecret: CHANNEL_SECRET,
});

Error Handling

messaging-api-line uses axios as HTTP client. We use axios-error package to wrap API error instances for better formatting error messages. Directly calling console.log with the error instance will return formatted message. If you'd like to get the axios request, response, or config, you can still get them via those keys on the error instance.

client.replyText(token, text).catch((error) => {
  console.log(error); // formatted error message
  console.log(error.stack); // error stack trace
  console.log(error.config); // axios request config
  console.log(error.request); // HTTP request
  console.log(error.response); // HTTP response
});

API Reference

All methods return a Promise.
