Bun

Send emails using Bun and the MailChannels Node.js SDK.

Prerequisites

• Create a MailChannels account
• Create an API key

1. Install

Add the mailchannels-sdk package dependency to your Bun project.

bun

bun add mailchannels-sdk

2. Configure your API key

Add your MailChannels API key to your .env file.

.env

MAILCHANNELS_API_KEY=your-api-key

3. Send email using HTML

Register a /api/send Route handler for your Bun app.

Use the html property to send an email with HTML content.

src/index.ts

import { MailChannels } from 'mailchannels-sdk'

const mailchannels = new MailChannels(process.env.MAILCHANNELS_API_KEY as string)

const server = Bun.serve({
  port: 3000,
  routes: {
    '/api/send': {
      POST: async () => {
        const { data, error } = await mailchannels.emails.send({
          from: 'Name <from@example.com>',
          to: 'to@example.com',
          subject: 'Test email',
          html: '<p>Hello World</p>'
        })

        if (error) {
          return Response.json(error, { status: error.statusCode || 500 })
        }

        return Response.json(data)
      }
    },
    '/api/*': Response.json({ message: 'Not found' }, { status: 404 }),
    '/*': () => new Response('Not found', { status: 404 })
  }
})

console.info(`Listening on http://localhost:${server.port} ...`)
