This little app represents a list of to do tasks. The following functionality is implemented:

• add a new tasks; maximum input length is restricted to 20 symbols - validation is performed on input change and upon violation of the limit submit does not happen;
• show the list of tasks;
• delete a task with a designated button;
• switch completion status of a task by click on its description;
• filter tasks to show all, only active or only completed ones;
• show the quantity of tasks with each status (active, completed, all).

The project was bootstrapped with Create React App. Even though npm audit shows numerous vulnerabilities, the vulnerable packages (browserslist, postcss) are updated manually and no open issues exist.
React defines page structure.
Redux handles app state.
Semantin UI defines style for components. Note that some additional styling is applied through CSS as well.

Install Node 14.0 or later.
