Serverless-Boilerplate-Express-TypeScript VS Express

You can find more details in my open source boilerplate: https://github.com/ixartz/Serverless-Boilerplate-Express-TypeScript where I'm using TypeScript.

You can check out the GitHub repo for more details at: Node.js Boilerplate with Serverless and Prisma

As you might know, AWS has recently announced AWS Lambda Function URLs. This is a new feature that allows you to deploy your lambda behind a HTTPS endpoint without API Gateway. So, no need to set up a API gateway with related cost associated to it or add complexity to your serverless architecture for a single lambda function. I'm the author of a Serverless Boilerplate Template that uses Express.js with AWS Lambda. Usually, I got a lot of questions on why I add Express.js to my boilerplate code. Indeed, adding Express.js with API Gateway is redundant and it's not necessary. It'll increase the deployed package size. Now with Lambda Function URLs, you don't need an API Gateway all the time. Without API gateway, all HTTP requests are sending to one lambda function. That means you need a Web framework to handle the request like Express.js. To be clear and avoid any confusion, API gateway is still a solution. But, based on your context and your needs, you can choose to use Lambda Function URLs and remove the API gateway. In the past, a lot of people were suggesting me to remove Express.js from my starter code. Now with Lambda Function, I'm not sure if it's a good idea to remove it from your boilerplate code. What is your thoughts on this?

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.

Now we can install both Express and Socket.io libraries:

app.listen(3000); ``` Now you can run your server by executing `node index.js`. Your web application will be accessible at http://localhost:3000/, where you'll see "Hello, world!" displayed in your browser. Congratulations! 🎉 You've successfully set up basic routing with Express.js! This guide covered only the tip of the iceberg when it comes to utilizing Express.js features. Explore its extensive documentation (https://expressjs.com/) to discover more possibilities. Remember, with Express.js, you have the power to build efficient and scalable web applications. Happy coding!

Converting a large Express.js application from JavaScript to TypeScript can be a challenging task. For many applications, this represents a significant portion of their technical debt, as the process may span many days, if not months, and new changes are typically not allowed during the conversion.

Nitro is a nice https webserver that you can deploy everywhere. Comparing it to express, it doesn't need weird middlewares for json, it has a simple way to support caching, a file system router, tasks and scheduled tasks that avoid quite a few shell scripts, db:migrations etc, plugins, KV storages, SQL connectors, websockets...

ExpressoTS fully supports Express middleware.
