Add a button below the list of tasks called " Clear" that when clicked it clears all the tasks.įeel free to comment below incase you need further assistance.Once task is completed, instead of strike-through you can make it to disappear.Many popular React packages are adding support for Hooks so developers can leverage their APIs in functional components. With Hooks, developers can write cleaner components with less boilerplate compared to a class component. You can do the following if you would like to learn more. React Hooks were introduced with the release of React 16.8.0 to much excitement. The above boilerplate can be used to extend the App to include more functionalities around the App. You have also gone through other aspects of React and ES6 JavaScript. App.css ' function App () Ĭongratulations! You have now built a To do list App using React hooks and styled-components. In the src folder, open App.js and get rid of everything between tags. This utility function will be imported and invoked when we want to make API requests.Enter fullscreen mode Exit fullscreen modeĬd into todo-list and yarn start OR npm start if using npm. Separating your app’s concerns based on logic, not lifecycle hooks.

Sharing stateful logic without render props or higher-order components. Some benefits are Isolating stateful logic, making it easier to test. For now, we’re just going to add one helper function inside a file named, you guessed it ?, Helpers.ts. What are hooks They’re functions that give you React features like state and lifecycle hooks without ES6 classes.

The utils folder is where our Custom Hooks, constants and helper functions will live.

React todolist hooks how to#
If you’re not too sure on how to get TypeScript working with Facebook’s boilerplate, you can quickly check out another post of mine here and just work your way through the part that deals with this initial setup step and removing the boilerplate code that we won’t need.įor styling purposes I’ll be using styled-components and reactstrap, validator for input validation and uuid to generate unique id’s.

I’ll be using create-react-app with TypeScript for this exercise. I had the privilege of sharing this post in presentation format at the virtual version of ReactEurope 2020, if you’re keen to watch the video walk-through, go ahead and check out the video below. If you enjoy the post, feel free to buy me a coffee here ☕️ ?.

I wouldn’t say this approach is better, but if you’re like me and you prefer to delve into building a small app that demonstrates as well as explains what you’re learning, then this one is for you ?. The aim of this post is to provide developers with an alternative to the other guidelines that are out there. I should say this from the onset, there are a ton articles and tutorials on understanding React Hooks, and most of the one’s I’ve come across are really good. Since this todo list app will utilize React hooks for managing state there is no need to use. I think it’s still good to have a pattern whereby we have container components that have our business logic and presentation components that have the responsibility of UI presentation. There will be one occasion where you will also use useRef hook. That being said, not every function component you write has to make use of Hooks. With Hooks, function components can be used to manage state, make use of a component’s lifecycle events, as well as connect to the context of React apps.Īs a result, our function components are going to be a little more complex than what we may be used to. Features that were previously exclusive to class based components can now be utilised with function components. Learning React Hooks can be a little bit intimidating because it’s a different way of working with components.
