React SDK quick start guide
In this quick start guide you'll learn how to start delivering your media from Cloudinary using React.
Tip
If you are not familiar with Cloudinary, we advise starting with the Developer get started guide for a high-level overview of integrating Cloudinary into your code, and an introduction to the main concepts. You may also find our Glossary helpful to understand Cloudinary-specific terminology.
Two libraries are required:
- frontend-frameworks for rendering media using the React framework.
- js-url-gen for building transformations.
Tip
To get a more in-depth understanding of the architecture, you may want to start from the React SDK introduction. 1. Install packages
Install the required packages using the NPM package manager:
2. Add Cloudinary to your code
Note
This step assumes that you have assets already uploaded in your account. To upload files within your app, see React SDK image and video upload. Additionally, you can use the CLI to upload files programmatically, or log into your Media Library to upload files manually.// 1. Import classes // ================== import React from 'react' import {AdvancedImage} from '@cloudinary/react'; import {Cloudinary} from "@cloudinary/url-gen"; // Import any actions required for transformations. import {fill} from "@cloudinary/url-gen/actions/resize"; const App = () => { // 2. Set your cloud name //======================== // Create a Cloudinary instance and set your cloud name. const cld = new Cloudinary({ cloud: { cloudName: 'demo' } }); // 3. Get your image //=================== // Instantiate a CloudinaryImage object for the image with the public ID, 'docs/models'. const myImage = cld.image('docs/models'); // 4. Transform your image //========================= // Resize to 250 x 250 pixels using the 'fill' crop mode. myImage.resize(fill().width(250).height(250)); // 5. Deliver your image // ========================= // Render the image in a React component. return ( <div> <AdvancedImage cldImg={myImage} /> </div> ) };
