How can you make a login page in this code?

After installing create-react-app, uuid, axios and react-router, I loaded the code in this repo and got a compile error in app.js. To fix the problem, I commented out the following:

import uuid from 'uuid';
res.data.id = uuid.v4(); in the addTodo method

On start with provided data, checkboxes are all unchecked but some of items are completed.
IMO there should be :
checked={this.props.todo.completed}
in line 19 in TodoItems.jsx

Hey,

First of all nice work with the videos on youtube. While watching your video I noticed that the markComplete function is mutating the original state.

Can be easily spotted with this example:

const todos = [{
  id: 1, title: 'Learn React', completed: false
}, {
  id: 2, title: 'Mutate state', completed: false
}];

const newState = todos.map(todo => {
  if (todo.id === 2) {
    todo.completed = !todo.completed;
  }
  return todo;
});

Error in react_crash_todo/src/components/AddTodo.js
Error appears after submitting the form.

"dependencies": {
"react": "^16.9.0",
"react-dom": "^16.9.0",
"react-scripts": "3.1.1"
}

Hello! Importing is not working for uuid. It says :

Failed to compile.
./src/App.js
Attempted import error: 'uuid' does not contain a default export (imported as 'uuid').

But this is working :
const uuid = require('uuid');

Why it is showing error?

Hello Brad, first thanks for the great tutorial crash course, but the final code has some issues about the add new todo process. The new todos had same ids of '201', in my researchs i've found that this is a http code related. Searching in the comments i've found a fix from a user "David Ernest"
(His channel). The fix is listed below:

In App.js, at axios.post '.then' for appTodo change to this:

.then(res => {
      res.data.id = uuid();  //or uuid.v4()
      this.setState({ todos: [...this.state.todos, res.data] });
    }); 

This should make your code work because this manually overwriting the id property that comes back from the JSON Placeholder API, as the Youtube user said!

Hope this help!
