SendGrid Send

You don't need a library to use a REST API. Just create a valid JSON body, and make a POST request to SendGrid.

Features

1. TypeScript support - be confident about your JSON.
2. ESM and CJS - choose either import or require.
3. Use the Fetch API or any HTTP library[^1] of your choice.
4. Literally 0kb - import a single-line JavaScript function.

[^1]: @sendgrid/mail uses Axios - @sendgrid/client depends on it.

export const generateSgSendBody = (requestBody) => requestBody;

The requestBody is typed according to the SendGrid API documentation.

Usage

Please reference the SendGrid API documentation for all supported values.

With Fetch API

The generateSgSendRequest function returns a Request object which can be used with the Fetch API. The URL, method, and HTTP headers are all set.

import { generateSgSendRequest } from 'sendgrid-send';

await fetch(
  generateSgSendRequest(
    {
      from: { email: '[email protected]' },
      personalizations: [{ to: [{ email: '[email protected]' }] }],
      subject: 'SendGrid and the Fetch API is awesome.',
      content: [{ type: 'text/plain', value: 'Best of both worlds.' }],
      // ...
    },
    '<<YOUR_API_KEY_HERE>>'
  )
);

Generate Body

npm i sendgrid-send

import { generateSgSendBody } from 'sendgrid-send';
// const { generateSgSendBody } = require('sendgrid-send');

const body = generateSgSendBody({
  from: { email: '[email protected]' },
  // ...
});

// Make a HTTP request using the method of your choice.
// e.g. node-fetch, cross-fetch, axios, got, undici

await fetch('https://api.sendgrid.com/v3/mail/send', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer <<YOUR_API_KEY_HERE>>',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(body),
});

Import Type Only

npm i sendgrid-send -D

import type { SendGridRequestBody } from 'sendgrid-send';

const body = {
  from: { email: '[email protected]' },
  // ...
} satisfies SendGridRequestBody;
