Needs advice on code coverage tool in Node.js/ExpressJS with External API Testing Framework

Hello community,

I have a web application with the backend developed using Node.js and Express.js. The backend server is in one directory, and I have a separate API testing framework, made using SuperTest, Mocha, and Chai, in another directory. The testing framework pings the API, retrieves responses, and performs validations.

I'm currently looking for a code coverage tool that can accurately measure the code coverage of my backend code when triggered by the API testing framework. I've tried using Istanbul and NYC with instrumented code, but the results are not as expected.

Could you please recommend a reliable code coverage tool or suggest an approach to effectively measure the code coverage of my Node.js/Express.js backend code in this setup?

Hello, I am building a website for a school that's used by students to find Zoom meeting links, view their marks, and check course materials. It is also used by the teachers to put the meeting links, students' marks, and course materials.

I created a similar website using HTML, CSS, PHP, and MySQL. Now I want to implement this project using some frameworks: Next.js, ExpressJS and use PostgreSQL instead of MYSQL

I want to have some advice on whether these are enough to implement my project

Hi,

I am a student and a junior developer who is a graduating candidate in comp sci major. I am about to start building my final year project which is a real-time messaging application for software developers to Enhance Knowledge Exchange and Problem Solving. It is mainly a chat application with more enhanced features. I am planning to use React and React Native for the frontend and cross-platform mobile apps, Node.js and ExpressJS for the backend, GraphQL for fetching and manipulating data from the backend and PostgreSQL for the database, and finally Socket.IO for the real-time chatting and communication. I would highly appreciate it if anyone here with experience in building similar apps to tell me if I made a good choice or suggest better tech stacks.

Thanks in advance.

I'm interested in web back-ends. Currently, I spent some time learning MongoDB + ExpressJS + TypeScript for back-end. I can make a basic application that can Create Read Update and Delete user data (super basic with some authentication that requires you to sign-in to read and be a valid user to delete a user). My current situation is that I wish to have a job in this area as I loved creating this simple application, what are the ways I can get into the industry without having any Computer Science degree?

ExpressJS Alternatives & Comparisons

What are some alternatives to ExpressJS?
Koa
Koa aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware.
React
Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
Flask
Flask is intended for getting started very quickly and was developed with best intentions in mind.
Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Golang
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
