## [Live demo](http://rebilly.github.io/ReDoc/)
[
](https://github.com/Rebilly/generator-openapi-repo#generator-openapi-repo--)
## Features
- Extremely easy deployment
- The widest OpenAPI features support (yes, it supports even `discriminator`)
- Neat **interactive** documentation for nested objects
- Code samples support (via vendor extension)
- Progressive loading with `lazy-rendering` options
- Responsive three-panel design with menu/scrolling synchronization
- Integrate API Introduction into side menu - ReDoc takes advantage of markdown headings from OpenAPI description field. It pulls them into side menu and also supports deep linking.
- High-level grouping in side-menu via [`x-tagGroups`](docs/redoc-vendor-extensions.md#x-tagGroups) vendor extension
- Multiple ReDoc instances on single page ([example](demo/examples/multiple-apis/index.html))
## Roadmap
- [x] ~~performance optimizations~~
- [x] ~~better navigation (menu improvements + search)~~
- [ ] ability to simple branding/styling
- [ ] built-in API Console
- [ ] docs pre-rendering (performance and SEO)
## Releases
We host the latest and all the previous ReDoc releases on GitHub Pages-based **CDN**:
- 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 this file is updated with each release of ReDoc and may introduce breaking changes. **Not recommended to use in production.** Use particular release or `v1.x.x`.

## Deployment
### TL;DR
```html
ReDoc
```
That's all folks!
### 1. Install ReDoc (skip this step for CDN)
Install using [bower](bower.io):
bower install redoc
or using [npm](https://docs.npmjs.com/getting-started/what-is-npm):
npm install redoc --save
### 2. Reference redoc script in HTML
For **CDN**:
```html
```
For bower:
```html
```
For npm:
```html
```
### 3. Add `` element to your page
```html
```
### 4. Enjoy :smile:
## 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](http://swagger.io/specification/#vendorExtensions):
* [`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#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)
### `` tag attributes
* `spec-url` - relative or absolute url to your spec file;
* `scroll-y-offset` - 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;
`scroll-y-offset` 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);
* `suppress-warnings` - if set, warnings are not rendered at the top of documentation (they still are logged to the console).
* `lazy-rendering` - 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](\\rebilly.github.io/ReDoc) for the example.
* `hide-hostname` - if set, the protocol and hostname is not shown in the operation definition.
* `expand-responses` - specify which responses to expand by default by response codes. Values should be passed as comma-separated list without spaces e.g. `expand-responses="200,201"`. Special value `"all"` expands all responses by default. Be careful: this option can slow-down documentation rendering time.
* `required-props-first` - show required properties first ordered in the same order as in `required` array.
## Advanced usage
Instead of adding `spec-url` attribute to the `` element you can initialize ReDoc via globally exposed `Redoc` object:
```js
Redoc.init(specOrSpecUrl, options)
```
`specOrSpecUrl` is either JSON object with specification or an URL to the spec in `JSON` or `YAML` format.
`options` is javascript object with camel-cased version of `` tag attribute names as the keys, e.g.:
```js
Redoc.init('http://petstore.swagger.io/v2/swagger.json', {
scrollYOffset: 50
})
```

## Development
#### Running local dev-server
- Clone repository
`git clone https://github.com/Rebilly/ReDoc.git`
- Go to the project folder
`cd ReDoc`
- Install dependencies
`npm install`
- _(optional)_ Replace `demo/swagger.yaml` with your own schema
- Start the server
`npm start`
- Open `http://localhost:9000`
Alternatively, Docker can be used by just running `docker-compose up`.
