ReactJS Evergreen Switch Component

  • Last Updated : 14 Jun, 2021

React Evergreen is a popular front-end library with a set of React components for building beautiful products as this library is flexible, sensible defaults, and User friendly. Switch Component allows the user to toggle the state of a single setting on or off. We can use the following approach in ReactJS to use the Evergreen Switch Component.

Switch Props:

  • id: It is used to denote the id attribute of the radio.
  • name: It is used to define the name attribute of the radio.
  • value: It is used to denote the value attribute of the radio.
  • height: It is used to define the height of the switch.
  • checked: The switch is checked when this is set to true.
  • onChange: It is a function that is called when the state changes.
  • disabled: The switch is disabled when this is set to true.
  • isInvalid: The switch is invalid when this is set to true.
  • appearance: It is used for the appearance of the checkbox.
  • hasCheckIcon: The switch has a check icon when this is set to true.
  • defaultChecked: The switch is true by default when this is set to true.

Creating React Application And Installing Module:

  • Step 1: Create a React application using the following command:

    npx create-react-app foldername

     



  • Step 2: After creating your project folder i.e. foldername, move to it using the following command:

    cd foldername
  • Step 3: After creating the ReactJS application, Install the required module using the following command:

    npm install evergreen-ui
