Express VS Koa

Finally, I’ve chosen Express.js to build the API server. Express is a flexible Node.js web application framework that provides a robust set of features for web and mobile applications. Its simplicity and flexibility make it an ideal choice for the CMS project, allowing us to build powerful APIs with minimal hassle.

I use Express and Jest, but only enough to give you something to start with. You can substitute these out for your favorite web and test framework.

The API is a powerful blend of Node.js + Express. When evaluating backend combinations, a crucial aspect is that it can be deployed in any environment. Hence, vendor-locked options like Next.js were excluded from the candidate list.

After searching for hours and hours, I finally found an issue requesting to Dockerize the application. It was a full-stack social media application called ChatRoom, with a React Frontend and an Express.js Backend. Even though the project was fairly new, and not super complex, it was exactly what I was looking for this time.

Community stats: The official Express GitHub repository has 62.1k stars and 11.7k forks. The Express mailing list has over 5000 discussions which can be used as an issue library when you encounter a bug while developing an Express application.

Express is the most popular and minimalistic web framework for NodeJS. Express is designed to simplify the backend application development with a robust set of features including routing, middleware, error handling, and templating.

Express: Express is a fast, unopinionated, minimalist web framework for Node.js.

To demonstrate how to set up preview environments for a GitHub repository, we'll work with an example repository containing a basic Node.js web app built with Express. The application responds to requests with a simple "hello world" message.

Use NPM to install the plugin package, express web server package, and the Ably client library:

In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

The initial step is to create our entry point, from where the page will be rendered. In this case, we will use the koa framework.

Koa.js: By the team behind Express, Koa.js utilized async/await for middleware, resulting in cleaner and more readable code.

Koa -Next Generation Node Microservice Framework

Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

There are lot of different frameworks out there. If you learn one, there is no guarantee that the next job you find will use the same. For example if you learn Express and the next one used Koa or Nest.

Koa.js is a minimal and flexible Node.js web application infrastruc­ture, which provides a robust set of features for web and mobile applica­tions. It is an open-source framework developed and maintained by the creators of Express.js, the most popular web framework for Node.js.

Speaking of which... there's a long-standing issue with express when it comes to async route handlers. There's backstory to this is complicated and controversial, but the tl;dr: is that (in my humble, and very controversial, opinion) you can use express-async-errors as a workaround hack for legacy projects, but if you're starting a new project you should avoid Express and switch to Koa instead.
