Express VS fastify

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:

For example, Fastify removed the instanceof operatorfrom its codebase because it was causing problems for those developers that rely on jest as a testing framework.

Both are frameworks but NextJs is for Forntend (web app in browser that use ReactJs under the hood) and NestJs is for Backend (server app running on a server witch use Express or Fastify). The only thing similar between them is the typed language in which they were written.

Restify & Fastify Hapi

Fastify

In setting out to build this service, we wanted to use gRPC for its APIs. We’ve been reaching for REST when building APIs so far, primarily out of necessity, i.e., our public APIs needed auto-generated client SDKs and docs for developers working with them. We built those APIs with Fastify and Typebox but felt burned by a code-first approach to generating an OpenAPI spec. I’ll spare you the details and save that experience/learning for another article. Suffice it to say we love gRPC’s schema-first approach. This blog post summarizes our feelings well

Fastify – Fast and Low overhead web framework

Custom Functions are powered by Fastify (a light-weight Node.js framework that claims to be faster than Express.js), so they’re extremely flexible.

We’ll be using Fastify as the framework of choice. Fastify is a fast (as the name implies) and low-overhead server in Node. It has grown in popularity, recently crossing the 1 million weekly download mark on npm. I’m a fan of Fastify’s plugin architecture, and the ecosystem is quite impressive, boasting over 250 core and community plugins.
