React component for AsyncAPI specification. Available also as a Web Component, but not only.
Overview
The official React component for AsyncAPI specification. It allows you to render the documentation of your asynchronous API provided in the AsyncAPI specification format and validate this specification. You can fully restyle the component using your own styles.
Prerequisites
react
(version 16.8.0 or higher)
Installation
Run this command to install the component in your project:
npm install --save @asyncapi/react-component
Check out this sandbox application that uses the React component:
Using in React
Check a simple example which shows passing the inline AsyncAPI specification with custom configurations:
import * as React from "react";
import { render } from "react-dom";
import AsyncApiComponent, { ConfigInterface } from "@asyncapi/react-component";
const schema = `
asyncapi: '2.0.0'
info:
title: Example
version: '0.1.0'
channels:
example-channel:
subscribe:
message:
payload:
type: object
properties:
exampleField:
type: string
exampleNumber:
type: number
exampleDate:
type: string
format: date-time
`;
const config: ConfigInterface = {
schemaID: 'custom-spec',
show: {
operations: false,
errors: false,
},
};
const App = () => <AsyncApiComponent schema={schema} config={config} />;
render(<App />, document.getElementById("root"));

Props
The list of props for the AsyncAPI React component includes:
-
schema: string | AsyncAPIDocument | object | FetchingSchemaInterface
The schema
property is required and contains AsyncAPI specification. Use the string
type, the AsyncAPIDocument
type, parsed specification as JS object from AsyncAPI Parser or the FetchingSchemaInterface
object to fetch the schema from an external resource. For more information on what it contains and what it should look like, read AsyncAPI Specification.
-
config?: Partial<ConfigInterface>
The config
property is optional and contains configuration for the AsyncAPI component. For more information on the available configuration options, read the Configuration Modification document.
This property is concatenated with the default configuration.
NOTE: The Partial<T>
type means that every field in the T
type is optional.
Features
For a list and description of features offered by the AsyncAPI React component, see this directory.
Styles
Default styles
To use default styles import them as follows:
import "@asyncapi/react-component/styles/default.css";
import "@asyncapi/react-component/styles/default.min.css";
Custom styles
The AsyncAPI React component does not set any global fonts. This component allows the usage of your custom font-family
and other styling.
This can be done by defining the styles in a file or inline using a <style>
tag in the <head>
section of the page where you are using AsyncAPI React component.
Example custom styles (defined in the styles/custom.css
file):
html {
-moz-tab-size: 4;
-o-tab-size: 4;
tab-size: 4;
line-height: 1.15;
-webkit-text-size-adjust: 100%;
}
body {
margin: 0;
font-family: system-ui, -apple-system, Segoe UI, Roboto, Helvetica, Arial, sans-serif, Apple Color Emoji, Segoe UI Emoji;
}
If you are using the component in a project that uses a bundler like Webpack, don't forget to import the custom styles.
import "styles/custom.css";
import "@asyncapi/react-component/styles/default.min.css";
If you are using the standalone bundle, you can put the custom styles as a style sheet link or as an inline style in the <head>
section of the HTML code:
<head>
<link rel="stylesheet" href="./styles/custom.css">
<style>
html{-moz-tab-size:4;-o-tab-size:4;tab-size:4;line-height:1.15;-webkit-text-size-adjust:100%};
body{margin:0;font-family:system-ui,-apple-system,Segoe UI,Roboto,Helvetica,Arial,sans-serif,Apple Color Emoji,Segoe UI Emoji};
</style>
<link rel="stylesheet" href="https://unpkg.com/@asyncapi/react-component@latest/styles/default.min.css">
...
</head>
Custom logo
The AsyncAPI component supports the option to use a custom logo. By using the x-logo
custom extension in the InfoObject, a logo will be shown in the top left corner.
NOTE: The logo will only appear if the sidebar option is enabled.
asyncapi: 2.2.0
info:
title: Account Service
version: 1.0.0
description: This service is in charge of processing user signups.

Playground
This repository comes in with a Playground application. Test it to see the component in action and play with it before you use it in your application.
You can also run the Playground application locally by following this instruction from the development guide.
Modules
The @asyncapi/react-component
package has 3 crafted JS modules to be used in various environments:
esm
(ECMAScript Modules) is intended for use in a single-page applications with predefined environments like create-react-app
that are capable of resolving dependencies (via Webpack, Browserify, etc). It can also be used on the server side (for tasks like Server Side Rendering) when the application is using esm
.cjs
(CommonJS Modules) similar uses as for esm
modules, but using CommonJS modules.umd
(Universal Module Definition) is a dependency-free module that includes everything you need to serve AsyncAPI documentation (however React and ReactDOM dependencies must be served separately) on a single-page application that can't resolve npm module dependencies or in normal HTML page. We have 2 types of minified umd
bundles, with and without AsyncAPI Parser in paths:
@asyncapi/react-component/browser/index.js
@asyncapi/react-component/browser/without-parser.js
Development
For information on how to set up a development environment, write and run tests, follow the naming and architecture convention defined for the project in the Development Guide.
