LINE Notify is a LINE service that lets you send notifications to the subscribed users. Once a user subscribed to your service on LINE Notify, the user will become friends with LINE Notify automatically and you can send messages to the user through LINE Notify without extra cost.

If you want to have a clean project with LINE Notify, you could start from this example to develop your project. You can follow the following four steps to create your project:

Sending
  1. Download the code from line-notify example.
  2. Run yarn or npm install command to install all dependencies.
  3. Fill the .env file with the correct values.
  4. Run yarn dev or npm run dev to start the dev server.
