So, a file with name “index.js” needs to be created. So, index.js is the main entry file for the project. In package.json file, “index.js” is mentioned as the value of “main” property in the JSON. You can then replace “test”: “echo \”Error: no test specified\” & exit 1" with below snippet in package.json // package.json "scripts":

It’s a simple little package that automatically restarts your server when files change: npm install nodemon It is a JavaScript runtime built on google’s open source v8 engine. I also highly recommend installing Nodemon as a dev dependency. Node.js is a platform to build server-side event-driven applications using JavaScript.
Let’s just press “Enter” on every question to accept the defaults. This command will prompt you to answer some questions about the project, which you can choose to fill out or not.

It will describe what packages we need to run the server, how to run the server from the cli, and store what version of our code we are developing. Let’s create a project directory called express-api and move to it. Your versions may be slightly different than mine, but as long as both are there, we can get started. Open up your command prompt and type the following. We can test both using the -v flag, which will display the version. Once installation is done verify your installation with below commands.

If you don’t have Node installed, download from here. This makes it especially beginner-friendly.įinally, the differences in the frameworks are not big for many purposes - especially for a single API, or serving static assets, migration to another framework is easily possible.Our first prerequisite is making sure Node.js and npm are installed globally on the computer. The entire ecosystem is better equipped and there are more resources to Express. For me and many others, what Express offers is completely sufficient. Despite the superior performance of Fastify, I will primarily stay with Express. To be fair, the benchmarks that show such performance differences are often very unrealistic situations - in reality, hardly any web server would be bombarded with so many requests at once.Įspecially since the hardware of the system also plays a decisive role. In terms of performance, Fastify is superior.
It seems to be the fastest web framework in the Node.js world. But I also read it in other benchmarks, not least on the official site of Fastify. The results are clear - Fastify is faster than Express.js and even faster than Bare Node.js. This is the command I used for each API: wrk -t12 -c400 -d10s 12 is the number of threads we use, 400 the number of concurrent connections. On Linux, it can be installed with sudo apt-get install wrk. On macOS, it can be installed with brew install wrk. But because of the HTTP-versions, there are problems with Fastify and AB is very old anyway. In the last article, I used apache bench.
I simply executed the APIs with the node command, no PM2 or nodemon was used. Each server was tested individually, all other request sources except the load-testing tool were switched off. I made sure that the same conditions prevailed in all tests.

The Benchmarkįor the benchmark, I use the MacBook Pro 13 inch 2018, with the 4-core Intel i5 processor. With Express and Fastfiy, this was automatically in the header. For the content-type I had to specify utf-8 manually. Without the if-statement this node server would answer every request. I added the if-statement to make it fair - after all, the other two APIs check the route when requesting. Comments: In bare Node.js there is no res.send.
