⚛️ Learn React Router 6 with Bob Ziroll ⚛️

Hello and welcome! This is the starter code for each scrim in Bob Ziroll's Learn React Router 6 course on Scrimba! ⚛️

To follow the course on Scrimba's interactive code-learning platform, head to the Learn React Router 6 page on Scrimba!

Please read this carefully!

This README file is the best "single source of truth" for you to see updates made to the course if you're coming from the freeCodeCamp YouTube channel!

As time passes, dependencies can sometimes become outdated or start exhibiting bugs that weren't there when I first recorded the course.

In the version of this course on Scrimba, it's easy for me to add quick updates and new lessons. However, the course on YouTube is frozen in time and unchangeable. So please come check the "Updates" section below often, as you may find there are important updates that can help you avoid common bugs.

Setup

In "Lesson 90: Challenge - Protected Routes in VanLife Part 2" (https://youtu.be/nDGA3km5He4?t=23735) (05 - Actions and Protected Routes/14 - Challenge - Protected Routes in VanLife - Part 2), I remove return null from my inline loaders which was incorrect. What I should have followed up with was to add return null to the end of the requireAuth outside of the if statement. The code at the end of this challenge should be:

import { redirect } from "react-router-dom"

export async function requireAuth() {
    const isLoggedIn = false
    
    if (!isLoggedIn) {
        throw redirect("/login")
    }
    return null
}

This way, for the loaders that are only running await requireAuth(), at least something (well, null, if you can call that "something" 😂) will get returned if the user is logged in.

With an update made to v 6.4.5 of React Router, Mirage JS is causing some errors when using the redirect function from React Router. tl;dr: a library that Mirage JS is using under the hood (pretender) uses a polyfill for fetch, and that polyfill does not adhere to the fetch specifications, in that it does not return a response with a body property. In React Router 6.4.5, they included a new check to make sure that a response has a body property, which makes any redirect call in React Router fail.

You can work around this issue by modifying the response that comes back when calling redirect, like so:

Instead of

return redirect("new-url")

You can capture the response in a variable and add a body property manually:

const response = redirect("new-url)
response.body = true  // It's silly, but it works
return response
