You can swap these for other tech stacks (Django, Flask, Laravel, Vue, Svelte, etc.) - concepts are the same.</p> <p><strong>1st step:</strong> Create your backend data/list. Always use JSON for data exchange unless you need files. Make sure you understand that where your back-end is set up, i prefer to do it with separate folder like (create-users-management-server), cause it will make our work organized. </p> <p><strong>2nd step:</strong> Test your back-end data by running it on server. In combination of node js and express, run (node server/index.js) or (nodemon). If all is Okay, your back-end setup is done.</p> <p><strong>3rd step:</strong> Now we will work on front-end code, when you fetch data, we might get an error, but no worry, it's for disabled CORS on the back-end, simply enable it by using this (app.use(cors()) ); Then you can see that the error is gone. </p> <p><strong>4th step:</strong> Yeah now you can get access data from your back-end, check your console.log, and you can easily update it on your UI for show to users. </p> beginners basic react webdev
