![]() Because we do not have form fields directly within this component, we have to have a way to set the state as we go (using the onChange attribute in each component call).Both Node.js and Reac.js are JavaScript technologies, yet both of them are entirely different things. We also have a new method called setValue. We then reset all the fields so they will appear empty after submission. On submit, we send all the data to the parent component to do the actual saving to the server. The other bits of data can always be added later, but we are just going to focus on the data that we want to display. ![]() All we have to do is uncomment those lines, and we have this: var DonationBox = React.createClass(Īs you can see, we’ve added new states for each piece of data we plan on saving. The original file was set up with some of the code needed to post and read data, but some parts were commented out, since we had no server to do the work. The index file from the previous tutorial remains the same, but now we are going to be pulling data from a file, then posting new form entries to the file. The files with all the revisions are provided above. I will be using the same files I created for the error handling tutorial, with some simple revisions that will make it possible to read and save data. Making revisions to a React user interface You will need to read and follow the directions in most of the beginner’s Node.js tutorial in order to create the server that will be used later in this tutorial.An editor with code highlighting capability is preferable. You can use just a plain text editor, although Notepad++ is popular on Windows, and TextMate is popular on Mac machines. You will need to download a text editor of some sort.You will need to use the React library, although we will be using CDN links to get around that during testing.In addition, I will be using many of the same functions from my other React tutorial, so you may want to read that one as well. For a beginner’s guide to React, please see my past tutorial. You must have basic knowledge of React.js and JavaScript.If you are keen to learn React from the ground-up feel free to check Learn and Understand React JS on Zenva Academy which covers all the basics + lots of bonus topics like React Router and Flux. ![]() Instead, you can check out K12-friendly web development courses on Zenva Schools that will be perfect for the classroom. We also don’t recommend React or Node for classroom teaching. For those a bit new to these topics – or even just in need of a review – you might want to try some online courses first to make sure you’re ready. Īs hinted above, we do assume that you know the fundamentals of web development (especially JavaScript which heavily plays into both Node and React). You can download all the files used in this tutorial from here. ![]() In fact, I’ll be using the same files from my form error handling React tutorial, with a few updates that will allow the saving and reading of information from a file or database.ĭownload the tutorial files & prerequisites Although our Node server will be similar, our front-end React interface will have a few extra complications. The main React Facebook tutorial does something similar to what we will be doing with this tutorial, and they also provide a Node server, as well as many other server examples within their download files. Lucky for us, we already have a tutorial on the basics of Node right here! One of the most common pairings is React.js with Node.js. React is a user interface library, so it is common to use a different library or framework to do all the back-end work. That is the part we will cover in this tutorial – but if you need some refreshing on React, especially on Props & States, feel free to read the linked resources. React is a front-end library, providing no easy way to save to, or read information from, a database or file. In my last two tutorials, I covered the basics of React.js and form error handling in React.js. If you’re ready to explore some core web fundamentals, let’s jump into it. In this tutorial, we’re going to explore how to combine React, Node.js, and various techniques to allow users to submit forms – and then save that data so we can use it for whatever backend purposes we might need. ![]() While there are multiple ways to deal with forms on the web, the popular React library offers a unique and easy way to do it. ![]()
