|
|
- Simple integration with `create-react-app` ([sample](https://github.com/APIs-guru/create-react-app-redoc))
|
|
- Branding/customizations via [`theme` option](#redoc-options-object)
|
|
|
|

|
|
|
|
## Releases
|
|
**Important:** all the 2.x releases are deployed to npm and can be used via jsdeliver:
|
|
- particular release, e.g. `v2.0.0-alpha.15`: https://cdn.jsdelivr.net/npm/redoc@2.0.0-alpha.17/bundles/redoc.standalone.js
|
|
- `next` release: https://cdn.jsdelivr.net/npm/redoc@next/bundles/redoc.standalone.js
|
|
|
|
Additionally, all the 1.x releases are hosted on our GitHub Pages-based CDN **(deprecated)**:
|
|
- particular release, e.g. `v1.2.0`: https://rebilly.github.io/ReDoc/releases/v1.2.0/redoc.min.js
|
|
- `v1.x.x` release: https://rebilly.github.io/ReDoc/releases/v1.x.x/redoc.min.js
|
|
- `latest` release: https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js - it will point to latest 1.x.x release since 2.x releases are not hosted on this CDN but on unpkg.
|
|
|

|
|
|
### TL;DR
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>ReDoc</title>
|
|
<!-- needed for adaptive design -->
|
|
<meta charset="utf-8"/>
|
|
<meta name="viewport" content="width=device-width, initial-scale=1">
|
|
<link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,700|Roboto:300,400,700" rel="stylesheet">
|
|
|
|
<!--
|
|
ReDoc doesn't change outer page styles
|
|
-->
|
|
<style>
|
|
body {
|
|
margin: 0;
|
|
padding: 0;
|
|
}
|
|
</style>
|
|
</head>
|
|
<body>
|
|
<redoc spec-url='http://petstore.swagger.io/v2/swagger.json'></redoc>
|
|
<script src="https://cdn.jsdelivr.net/npm/redoc@next/bundles/redoc.standalone.js"> </script>
|
|
</body>
|
|
</html>
|
|
```
|
|
That's all folks!
|
|
|
|
**IMPORTANT NOTE:** if you work with untrusted user spec, use `untrusted-spec` [option](#redoc-options-object) to prevent XSS security risks.
|
|
|
|
### 1. Install ReDoc (skip this step for CDN)
|
|
Install using [npm](https://docs.npmjs.com/getting-started/what-is-npm):
|
|
|
|
npm i redoc
|
|
|
|
or using [yarn](https://yarnpkg.com):
|
|
|
|
yarn add redoc
|
|
|
|
### 2. Reference redoc script in HTML
|
|
For **CDN**:
|
|
```html
|
|
<script src="https://cdn.jsdelivr.net/npm/redoc/bundles/redoc.standalone.js"> </script>
|
|
```
|
|
|
|
For npm:
|
|
```html
|
|
<script src="node_modules/redoc/bundles/redoc.standalone.js"> </script>
|
|
```
|
|
|
|
### 3. Add `<redoc>` element to your page
|
|
```html
|
|
<redoc spec-url="url/to/your/spec"></redoc>
|
|
```
|
|
|
|
### 4. Enjoy :smile:
|
|
|
|
|
|
## Usage as a React component
|
|
|
|
Install peer dependencies required by ReDoc if you don't have them installed already:
|
|
|
|
npm i react react-dom mobx@^4.2.0 styled-components core-js
|
|
|
|
Import `RedocStandalone` component from 'redoc' module:
|
|
|
|
```js
|
|
import { RedocStandalone } from 'redoc';
|
|
```
|
|
|
|
and use it somewhere in your component:
|
|
|
|
```js
|
|
<RedocStandalone specUrl="url/to/your/spec"/>
|
|
```
|
|
|
|
or
|
|
|
|
```js
|
|
<RedocStandalone spec={/* spec as an object */}/>
|
|
```
|
|
|
|
Also you can pass options:
|
|
|
|
```js
|
|
<RedocStandalone
|
|
specUrl="http://rebilly.github.io/RebillyAPI/openapi.json"
|
|
options={{
|
|
nativeScrollbars: true,
|
|
theme: { colors: { primary: { main: '#dd5522' } } },
|
|
}}
|
|
/>
|
|
```
|
|
|
|
Here are detailed [options docs](#redoc-options-object).
|
|
|
|
You can also specify `onLoaded` callback which will be called each time Redoc has been fully rendered or when error occurs (with an error as the first argument). *NOTE*: It may be called multiply times if you change component properties
|
|
|
|
```js
|
|
<RedocStandalone
|
|
specUrl="http://rebilly.github.io/RebillyAPI/openapi.json"
|
|
onLoaded={error => {
|
|
if (!error) {
|
|
console.log('Yay!');
|
|
}
|
|
}}
|
|
/>
|
|
```
|
|
|
|

|
|
|
|
## The Docker way
|
|
|
|
ReDoc is available as pre-built Docker image in official [Docker Hub repository](https://hub.docker.com/r/redocly/redoc/). You may simply pull & run it:
|
|
|
|
docker pull redocly/redoc
|
|
docker run -p 8080:80 redocly/redoc
|
|
|
|
Also you may rewrite some predefined environment variables defined in [Dockerfile](./config/docker/Dockerfile). By default ReDoc starts with demo Petstore spec located at `http://petstore.swagger.io/v2/swagger.json`, but you may change this URL using environment variable `SPEC_URL`:
|
|
|
|
docker run -p 8080:80 -e SPEC_URL=https://api.example.com/openapi.json redocly/redoc
|
|
|
|
## ReDoc CLI
|
|
|
|
[See here](https://github.com/Redocly/redoc/blob/master/cli/README.md)
|
|
|
|
## Configuration
|
|
|
|
### Security Definition location
|
|
You can inject Security Definitions widget into any place of your specification `description`. Check out details [here](docs/security-definitions-injection.md).
|
|
|
|
### Swagger vendor extensions
|
|
ReDoc makes use of the following [vendor extensions](https://swagger.io/specification/#specificationExtensions):
|
|
* [`x-logo`](docs/redoc-vendor-extensions.md#x-logo) - is used to specify API logo
|
|
* [`x-traitTag`](docs/redoc-vendor-extensions.md#x-traitTag) - useful for handling out common things like Pagination, Rate-Limits, etc
|
|
* [`x-code-samples`](docs/redoc-vendor-extensions.md#x-code-samples) - specify operation code samples
|
|
* [`x-examples`](docs/redoc-vendor-extensions.md#x-examples) - specify JSON example for requests
|
|
* [`x-nullable`](docs/redoc-vendor-extensions.md#x-nullable) - mark schema param as a nullable
|
|
* [`x-displayName`](docs/redoc-vendor-extensions.md#x-displayname) - specify human-friendly names for the menu categories
|
|
* [`x-tagGroups`](docs/redoc-vendor-extensions.md#x-tagGroups) - group tags by categories in the side menu
|
|
* [`x-servers`](docs/redoc-vendor-extensions.md#x-servers) - ability to specify different servers for API (backported from OpenAPI 3.0)
|
|
* [`x-ignoredHeaderParameters`](docs/redoc-vendor-extensions.md#x-ignoredHeaderParameters) - ability to specify header parameter names to ignore
|
|
* [`x-additionalPropertiesName`](docs/redoc-vendor-extensions.md#x-additionalPropertiesName) - ability to supply a descriptive name for the additional property keys
|
|
|
|
### `<redoc>` options object
|
|
You can use all of the following options with standalone version on <redoc> tag by kebab-casing them, e.g. `scrollYOffset` becomes `scroll-y-offset` and `expandResponses` becomes `expand-responses`.
|
|
|
|
* `disableSearch` - disable search indexing and search box.
|
|
* `expandDefaultServerVariables` - enable expanding default server variables, default `false`.
|
|
* `expandResponses` - specify which responses to expand by default by response codes. Values should be passed as comma-separated list without spaces e.g. `expandResponses="200,201"`. Special value `"all"` expands all responses by default. Be careful: this option can slow-down documentation rendering time.
|
|
* `hideDownloadButton` - do not show "Download" spec button. **THIS DOESN'T MAKE YOUR SPEC PRIVATE**, it just hides the button.
|
|
* `hideHostname` - if set, the protocol and hostname is not shown in the operation definition.
|
|
* `hideLoading` - do not show loading animation. Useful for small docs.
|
|
* `hideSingleRequestSampleTab` - do not show the request sample tab for requests with only one sample.
|
|
* `expandSingleSchemaField` - automatically expand single field in a schema
|
|
* `jsonSampleExpandLevel` - set the default expand level for JSON payload samples (responses and request body). Special value 'all' expands all levels. The default value is `2`.
|
|
* `lazyRendering` - _Not implemented yet_ ~~if set, enables lazy rendering mode in ReDoc. This mode is useful for APIs with big number of operations (e.g. > 50). In this mode ReDoc shows initial screen ASAP and then renders the rest operations asynchronously while showing progress bar on the top. Check out the [demo](\\redocly.github.io/redoc) for the example.~~
|
|
* `menuToggle` - if true clicking second time on expanded menu item will collapse it, default `false`.
|
|
* `nativeScrollbars` - use native scrollbar for sidemenu instead of perfect-scroll (scrolling performance optimization for big specs).
|
|
* `noAutoAuth` - do not inject Authentication section automatically.
|
|
* `onlyRequiredInSamples` - shows only required fields in request samples.
|
|
* `pathInMiddlePanel` - show path link and HTTP verb in the middle panel instead of the right one.
|
|
* `requiredPropsFirst` - show required properties first ordered in the same order as in `required` array.
|
|
* `scrollYOffset` - If set, specifies a vertical scroll-offset. This is often useful when there are fixed positioned elements at the top of the page, such as navbars, headers etc;
|
|
`scrollYOffset` can be specified in various ways:
|
|
* **number**: A fixed number of pixels to be used as offset.
|
|
* **selector**: selector of the element to be used for specifying the offset. The distance from the top of the page to the element's bottom will be used as offset.
|
|
* **function**: A getter function. Must return a number representing the offset (in pixels).
|
|
* `showExtensions` - show vendor extensions ("x-" fields). Extensions used by ReDoc are ignored. Can be boolean or an array of `string` with names of extensions to display.
|
|
* `sortPropsAlphabetically` - sort properties alphabetically.
|
|
* `suppressWarnings` - if set, warnings are not rendered at the top of documentation (they still are logged to the console).
|
|
* `payloadSampleIdx` - if set, payload sample will be inserted at this index or last. Indexes start from 0.
|
|
* `theme` - ReDoc theme. Not documented yet. For details check source code: [theme.ts](https://github.com/Redocly/redoc/blob/master/src/theme.ts).
|
|
* `untrustedSpec` - if set, the spec is considered untrusted and all HTML/markdown is sanitized to prevent XSS. **Disabled by default** for performance reasons. **Enable this option if you work with untrusted user data!**
|
|
|
|
## Advanced usage of standalone version
|
|
Instead of adding `spec-url` attribute to the `<redoc>` element you can initialize ReDoc via globally exposed `Redoc` object:
|
|
```js
|
|
Redoc.init(specOrSpecUrl, options, element, callback?)
|
|
```
|
|
|
|
- `specOrSpecUrl` is either JSON object with specification or an URL to the spec in `JSON` or `YAML` format
|
|
- `options` [options object](#redoc-options-object)
|
|
- `element` DOM element to put ReDoc into
|
|
- `callback` (optional) - callback to be called after Redoc has been fully rendered. It is also called also on errors with error as the first argument
|
|
|
|
```js
|
|
Redoc.init('http://petstore.swagger.io/v2/swagger.json', {
|
|
scrollYOffset: 50
|
|
}, document.getElementById('redoc-container'))
|
|
```
