Step 2.7: Connect Redux store to view (Exercise)

Lessons | Exercise | Demo

If you still have npm test running from the last step, stop it using ctrl+C. Start the app by running npm start from the root of the frontend-bootcamp folder. Click the "exercise" link under day 2 step 7 to see results.

At the beginning of this exercise, the "Add" and "Clear Completed" buttons do not work. We'll be fixing that in this step!

1. Open exercise/src/index.tsx and wrap <TodoApp> with <Provider> as instructed in the comment

2. Open exercise/src/components/TodoFooter.tsx and erase the "nullable" type modifier (i.e. the ?) in the interface definition of TodoFooterProps

3. Remove the export from export const TodoFooter = (props: TodoFooterProps) => {

4. Uncomment the bottom bits of code and fill in the implementation for mapStateToProps() and mapDispatchToProps() - feel free to use TodoListItem.tsx as a guide

5. Repeat steps 2, 3, and 4 for the TodoHeader.tsx file
