(please see solution in the bottom of doc)
This skills test is designed to allow you to showcase your development abilities to us. The test is administered through an online screen sharing session via zoom and will be recorded.
- Candidates will have one hour to complete the exercise.
- Google can be used to lookup helpful information as needed.
- Do not worry if you cannot fully complete the test within the allotted time, the purpose of the test is to allow us to determine skills and to get an insight into how you go about solving the problem.
- Please submit a live recording of the exercise.
Before joining the meeting link provided, please ensure that you have the following tools installed.
- Visual Studio Code
- Node JS version 16+
step 1.) clone this github repository. This repository contains a very basic react application with material ui components. step 2.) Fix any errors that prevent the project from being built and run. step 3.) On the main app.js page there is a todo form. You can see this component by clicking the ( M ) button Route this form to it's own page with the endpoint /todo step 4.) Create a table of todo items. When the user types into the textbox and clicks submit, the ui should have a table of these todo display. step 5.) On the newly created table, create a delete function that will remove a todo item.
Bonus points will be awarded for:
- improvements to user experience, styling, and for correcting any obvious errors in wording on the site.
- adding redux state management.
- hosting app on a platform like heroku
- Components (contains all the components for the application)
- router (this folder contains the router for the application)
- utils (this folder contains utility methods for the application)
- reducers (contains redux-toolkit/redux reducers)
