- The widest OpenAPI features support (yes, it supports even discriminator)
- Neat documentation for nested objects
- Code samples support (via vendor extension)
- Responsive three-panel design with menu/scrolling synchronization

That's all folks!
2016-01-25 00:15:50 +03:00
2016-07-28 19:58:04 +03:00
### 1. Install ReDoc (skip this step for CDN)
2016-01-25 00:15:50 +03:00
Install using [bower](bower.io):
bower install redoc
or using [npm](https://docs.npmjs.com/getting-started/what-is-npm):
npm install redoc --save
2016-07-28 21:36:43 +03:00
### 2. Reference redoc script in HTML
2016-07-28 20:17:56 +03:00
For **CDN**:
2016-07-28 19:58:04 +03:00
```html
<script src="https://rebilly.github.io/ReDoc/releases/latest/redoc.min.js"> </script>
```
For bower:
2016-01-25 00:15:50 +03:00
```html
<script src="bower_components/redoc/dist/redoc.min.js"> </script>
```
For npm:
```html
<script src="node_modules/redoc/dist/redoc.min.js"> </script>
```
2016-07-28 21:36:43 +03:00
### 3. Add `<redoc>` element to your page
2016-01-25 00:15:50 +03:00
```html
2016-07-28 21:54:58 +03:00
<redoc spec-url="url/to/your/spec"></redoc>
2016-01-25 00:15:50 +03:00
```
2016-07-28 21:36:43 +03:00
### 4. Enjoy :smile:
2016-01-25 00:15:50 +03:00
## Configuration
2016-10-31 13:32:17 +03:00
### 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).
2016-07-28 21:36:43 +03:00
### Swagger vendor extensions
2016-02-01 20:23:13 +03:00
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
2016-08-31 22:45:34 +03:00
* [`x-nullable`](docs/redoc-vendor-extensions.md#nullable) - mark schema param as a nullable
2016-02-01 20:23:13 +03:00
2016-08-04 19:14:50 +03:00
### `<redoc>` tag attributes
2016-07-28 21:54:58 +03:00
* `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;
2016-01-25 00:15:50 +03:00
`scroll-y-offset` can be specified in various ways:
2016-07-28 21:54:58 +03:00
* **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);
2016-07-29 18:20:38 +03:00
* `suppress-warnings` - if set, warnings are not rendered at the top of documentation (they still are logged to the console).
2016-11-30 14:23:24 +03:00
* `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 method definition.
2016-01-25 00:15:50 +03:00
## Advanced usage
Instead of adding `spec-url` attribute to the `<redoc>` element you can initialize ReDoc via globally exposed `Redoc` object:
```js
Redoc.init(specUrl, options)
```
2016-08-04 19:14:50 +03:00
`options` is javascript object with camel-cased version of `<redoc>` tag attribute names as the keys, e.g.:
2016-01-25 00:15:50 +03:00
```js
Redoc.init('http://petstore.swagger.io/v2/swagger.json', {
scrollYOffset: 50
})
```
