The unique values helps in easy access of the required data in the databases.Using UUIDs can help in securing the information provided and also keeps an unique identifier for each of the information’s provided.We can generate strong cryptographically created Random numbers using crypto.randomBytes(n) in node.js.It can run on node.js and all of the different browsers.There are 5 different versions of UUID which can be used in React Native.Import createStore from "./components/store" ĬonstrootElement = document.getElementById("root") Import Ĭonsole.log("persistedState", persistedState) The files used to implement the code below are:
It passes the index, which will uniquely identify a todo in our list.In the example below, we have imported uuidfrom react-native-uuid in the Addtodo.js file and UUID helps in making the unique ID for every task stored in the and it’s been used as:
deleteTodo: Clicking a todo’s IconButton fires this function. We map over each one and create a list item. Import React from 'react' import List from import ListItem from import ListItemSecondaryAction from import ListItemText from import Checkbox from import IconButton from import DeleteIcon from const TodoList = ( ) export default TodoList Here are the GitHub and CodeSandbox links. Display todos in a nice Material Design fashion. I recommend this for any language or library you want to try out. Todo lists are the most overused example for a good reason - they’re fantastic practice. I recommend you experiment, have fun, and use Hooks in your side projects, but not in production code until they’re stable. Don’t Use in Production!Īt the time of this writing, Hooks are in alpha. Avoiding ES6 classes, because they’re quirky, not actually classes, and trip up even experienced JavaScript developers.įor more detail see React’s official Hooks intro. Separating your app’s concerns based on logic, not lifecycle hooks. Sharing stateful logic without render props or higher-order components. Isolating stateful logic, making it easier to test. 
They’re functions that give you React features like state and lifecycle hooks without ES6 classes. React v16.7.0-alpha introduced Hooks, and I’m excited.
