Full Stack React & Firebase Tutorial - Build a social media app

description
In this full tutorial course, you will learn how to create a full stack, fully-featured social media application using React, Firebase, Redux, Express, and Material-UI. This intermediate tutorial covers things such as creating a backend REST API server with Node.js and Express, user login and authentication, image uploads, notifications, cloud functions, deploying to Firebase, and much more. 🎥 Course created by Classsed.

Here are some updates from @FrankJacquette: - Firebase no longer offers a free tier. You will have to set up an account and provide a credit card to use Firebase functions. - The current version of Busboy has broken the API described in the video. I recommend modifying your code to use the current version. - React-router-dom has API-breaking changes since the video was made. I recommend downgrading to version 5.x. - The instructor will occasionally introduce a bug in his work and repair it later. If your code isn't working, watch a little longer before assuming it's your issue. - The Redux code as implemented will cause an infinite page refresh loop under some circumstances. Clearing local storage and reloading the page will bypass this. - componentWillReceiveProps is deprecated and should be replaced with componentDidUpdate. There are several good pages out there describing how to do this. - Material UI has gone through a major version release since the video was produced. While everything in the video will continue to work, the documentation you'll find is for the current version of MUI and will be slightly different. Also, Grid has slightly different parameters. - Learn to code for free and get a developer job: https://www.freecodecamp.org Read hundreds of articles on programming: https://www.freecodecamp.org/news
