Mern tutorial10/13/2023 We will have all the dependencies stored in this file. Npm init this will start the package.json, you can just press yes to everything. The first thing we need to do is go to our directory and No, you should totally write documentation but let's start this tutorial. Once you have your project you can put Express.js on top of Node.js in a machine and it will act as a server for requests, you can also connect it to a database and it will server you as an intermediary between user events and the information you want to show. It allows you to build web applications and APIs. Node.JS is a runtime environment for JavaScript, it basically allows you to ruin everything with JavaScript anywhere.Įxpress or Express.js is the most famous backend framework for Node.js. You can find the next chapters of this series here: RESTful API with Node.JS, Express and MongoDB. NB: There's an 'older' stack, called LAMP) that consists of Linux, Apache, MySQL, PHP/Perl/Python, depending on your focus you might want to check it out But now we will focus on building the simplest RESTful API with Node and Express. At the end of it you will be able to create a full stack web app and deploy it anywhere with Docker. This is the first article of the MERN stack series that will progress in complexity. You can do everything with JavaScript or TypeScript nowadays. Additionally you also have Next.js, Nuxt.js, Remix.js, etc. There are variations where instead of React for the frontend you will find Angular, Vue, or even Svelte nowadays, although this last one is still not as popular. It's also fast as scalable, with millions of developers writing code and contributing to the documentation and the ecosystem. It's widely popular due to the fact that you can use JavaScript on the backend and frontend, or TypeScript. MERN stack stands for MongoDB, Express, React and Node.
