Getting started with React ColorPicker component

The following section explains the required steps to build the ColorPicker component with its basic usage in step-by-step procedure.

Dependencies

The following list of dependencies are required to use the ColorPicker component in your application.

|-- @syncfusion/ej2-react-inputs
    |-- @syncfusion/ej2-react-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-splitbuttons

Installation and configuration

You can use Create-react-app to setup the applications. To install create-react-app run the following command.

npm install -g create-react-app

Start a new project using create-react-app command as follows

create-react-app quickstart --scripts-version=react-scripts-ts

cd quickstart

create-react-app quickstart

cd quickstart

‘react-scripts-ts’ is used for creating React app with typescript.

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com public registry. You can choose the component that you want to install. For this application, we are going to use ColorPicker component.

To install ColorPicker component, use the following command

npm install @syncfusion/ej2-react-inputs –save

Adding ColorPicker to the application

Now, you can start adding ColorPicker component to the application. We have added ColorPicker component in src/App.tsx file using following code.

import { ColorPickerComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";

// initializes ColorPicker component
ReactDOM.render(<ColorPickerComponent/>);

import { ColorPickerComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";
// initializes ColorPicker component
ReactDOM.render(<ColorPickerComponent />);

Adding CSS reference

Import the ColorPicker component’s required CSS references as follows in src/App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";

Run the application

Use the npm run start command to run the application in the browser.

npm run start

The following example shows the default ColorPicker.
