Express VS Nest

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:

Community stats: NestJS has a large community with 60.5k stars and 7.2k forks on GitHub. 12,033 are tagged 'nestjs' on StackOverflow and an active discord community of 43,436 is also there to support fellow developers.

NestJS is a progressive framework for NodeJS for building server-side applications with JavaScript and TypeScript. NestJS follows a modular architecture enabling developers to create complex applications by organizing components into separate, independent modules, ensuring maintainability and reusability across various parts of the application.

For both, during my circle of development, I didn’t use TDD or other methods, I just wrote the services, classes, and modules and then I went to the tests, at this time I already had the base structure, so I opened Phind or ChatGPT-3 and I asked them to create a test to cover as much cases as possible using NestJS and its way of implementing tests, and in just a few seconds I have lots of tests ready! For a few of them I had to fix some small details, but overall, it was very good!

TypeORM is a very convenient ORM for JS apps. We use it with NestJS and running it on NodeJS.

We applied lots of things, techniques, and patterns, but in the end, I felt good with the application that was built. Now I also can say that I am feeling a bit up-to-date with the technologies that this project involved and the way of building software without a framework, it also reminds me, why I like so much of using Frameworks…. go NestJS 💪🏼

2023-05 – Angular v16 is here. Angular 16 also added support for ECMAScript decorators. However, some other frameworks built around decorators (and which were inspired by Angular?) have stated that they will not make changes toward ECMAScript decorators for now. For many of them, two important aspects are Metadata and Parameter decorators.

My NestJS project have 719 dependencies, after i saw the audit of next.js, nest.js didn't suprice me at all.

Ghostfolio is written in TypeScript and organized as an Nx workspace, utilizing the latest framework releases. The backend is based on NestJS in combination with PostgreSQL as a database together with Prisma and Redis for caching. The frontend is built with Angular.
