About

Notifier is a free tool to send notifications or messages to a variety of channels. The message is template-based. We store the template in Notifier then send a request to Notifier with matching payload to populate the message content.

Features

• Send email through SMPT
• Send email through Amazon SES using API key
• Send email through Brevo using API key
• Send message to Whatsapp
• Send message to Telegram
• Send message to Slack

Setup

1. Create templates.
   Templates are stored in /templates directory. We can create a template inside subdirectories under /templates. It is recommended we have the template with both html and txt format as the email sender function will try to render both formats. For example, we have /templates/en/sample.hello.html and /templates/en/sample.hello.txt. Then, in the HTPP request body we can select the template by setting the template field to en/sample.hello.

2. Create and configure .env file based on .env.sample.

3. Install dependencies.

   pnpm install

Running the app
