sendgrid-template-helper

The Sendgrid wrapper helps to send an email with a dynamic template stored on disk. It tries to create a dynamic template on the Sendgrid server via Sendgrid API v3, then caches the template ID locally for later uses.

Installation

Install sendgrid-template-helper via NPM:

npm install --save sendgrid-template-helper
# or
yarn add sendgrid-template-helper

Obtain a Sendgrid API Key

Setup Environment variables

In your development environment, export your Sendgrid API Key as follow:

export SENDGRID_API_KEY=YOUR_API_KEY

Send email

To send an email with dynamic email template (template is on your disk):

const path = require("path");
const Email = require("sendgrid-template-helper");

const settings = {
  apiKey: process.env.SENDGRID_API_KEY,
  prefix: "your_app_name_",
};

const email = new Email(settings);

email
  .send({
    to: "user@tdev.app",
    from: "admin@tdev.app",
    subject: `[Test] Sendgrid template helper`,
    templatePath: path.resolve(__dirname, "./dynamic-email-template.html"), // absolute path to your template
    dynamicTemplateData: {
      // your dynamic template data
      username: "user",
    },
  })
  .then(() => {})
  .catch(console.log);
