Note that with Node and Express you are not limited to just MongoDB but can use any type of database including PostreSQL, MySQL, and other relational databases. We don’t need it for our Hello, World app but you would for a more complicated app like a Blog. If you haven’t worked with JavaScript in the last few years, these three points should get you most of the way. MongoDB is a NoSQL database commonly used in Node applications. This guide occasionally uses some newer JavaScript syntax in the examples. But if I try running putting it into a separate file and running it via node program.js where program.js is console.log('Hello.
Now if I run this line from inside the node command line, it works just fine. The script I'm running is basically just a console.log('Hello World').

It might take you between 30 minutes and an hour, but as a result you won’t have to feel like you’re learning both React and JavaScript at the same time. I am running NodeJS LTS, node v6.10.0 npm 4.3.0 on Windows 10 圆4. If you don’t feel very confident, we recommend going through a JavaScript tutorial to check your knowledge level and enable you to follow along this guide without getting lost. React is a JavaScript library, and so we’ll assume you have a basic understanding of the JavaScript language. For example, “Introducing JSX” is the next chapter after this one. You can learn most of React by reading the “Main Concepts” guide chapters in the order they appear in the sidebar. If you’re reading this from a mobile device, you can access the navigation by pressing the button in the bottom right corner of your screen.Įvery chapter in this guide builds on the knowledge introduced in earlier chapters. You can find a list of all its chapters in the navigation sidebar. This is the first chapter in a step-by-step guide about main React concepts. You might find this guide and the tutorial complementary to each other. If you prefer to learn by doing, check out our practical tutorial.

This guide is designed for people who prefer learning concepts step by step. I have been trying to run one of the simple Hello World apps on my live hosting environment. This sample demonstrates a tiny Hello World node.js app for App Service Web App. Once you master them, you can create complex apps from small reusable pieces. In this guide, we will examine the building blocks of React apps: elements and components. Most pages in this guide will have editable examples like this one.
