sendgrid-nodejs VS Express

You will need an API key from SendGrid to use this package. You can get one by signing up for a free account at https://sendgrid.com/.

Formspark is a great service for this with a generous free tier. If you end up scaling up and need more and/or advanced transactional emails you may consider an email API like SendGrid, Amazon SES, or Waypoint.

SendGrid. An industry-leading email API with good deliverability and a comprehensive suite of analytics.

Solution: Read on to learn how to build a personal marathon training plan generator Streamlit-hosted app from personal workout data using the Strava API, LangChain agents, chains, few-shot prompt templating, PromptTemplates, OpenAI, and SendGrid. This can also be applied to personal training, nutrition, and more!

Sendgrid, Mailgun, or Postmark are great solutions if you have a need for transactional emails that are technical. I still prefer using Customer.io for this need. If you’re unsure what transactional emails are, check out this guide.

Email is sent via an event. I have a Lambda function triggered off an EventBridge rule in my serverless toolbox that will send an email via SendGrid. This allows me to reuse that functionality across all my projects, once again minimizing the amount of resources I have allocated in the cloud.

SendGrid

You could consider to use some email delivery service like Mailgun or Sendgrid. They offer free tiers and their servers are more accepted than some random self-hosted server.

First let's set up a Sendgrid account. Sendgrid has a free tier that enables 100 free emails a day. So let's sign up at https://sendgrid.com/.

Visit the SendGrid website and sign up for a free account. To create your account, provide the required information, including your email address and password.

On the index.js, environment variables are loaded, then we can find the API routing powered with Express. Here is the /send request:

Express: A lightweight framework for building web applications.

Now, we will create API using expressjs. When we created application using --ssr flag, the Angular CLI already took care of installing expressjs for us.

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Basic Knowledge of Express

Express.js Documentation

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.
