angular-swagger-ui

angular-swagger-ui is an angularJS implementation of OpenAPI UI

OpenAPI (aka Swagger) helps you documenting your RESTful API.

OpenAPI UI helps developers discovering your RESTful API by providing an online documentation with an integrated API explorer.

Warning

By default, only OpenAPI 2.0 is supported. To handle OpenAPI 3.0.0 please add module openapi3-converter see Enable OpenAPI 3.0.0. To handle OpenAPI 1.2 please add module swagger1-converter see Enable OpenAPI 1.2. To handle authorization please add module swagger-auth see Enable authorization To handle YAML please add module swagger-yaml-parser see Enable YAML

Demo

A sample app using angular-swagger-ui is available here:

http://orange-opensource.github.io/angular-swagger-ui

Quick Start

Install

npm install angular-swagger-ui

Dependencies

angularJS
bootstrap CSS
angular-ui-bootstrap (required only if using Authorization)

Getting Started

Include angular-swagger-ui as a dependency into your application

As some properties of OpenAPI specifications can be formatted as HTML:

You SHOULD include ngSanitize as a dependency into your application (avoids JS injection) if OpenAPI specifications are loaded from untrusted sources (see dist/index.html as an example)
You CAN add trusted-sources="true" as directive parameter (avoids embedding ngSanitize) if OpenAPI specifications are loaded from trusted sources (see src/index.html as an example)
You MUST at least choose one of the two previous solutions

<script type="text/javascript">
	// If directive has parameter trusted-sources="true"
	angular.module('yourApp', ['swaggerUi']);
	...
	// OR if you choosed to use "ngSanitize"
	angular.module('yourApp', ['ngSanitize', 'swaggerUi']);
	...
</script>

Create an HTML element in your angularJS application's template or in your HTML page

<div swagger-ui url="URLToYourOpenAPISpecification" api-explorer="true"></div>

Add swagger-ui.min.js and angular.min.js at the end of the body

<body>
 	...
 	<script src="yourPathToAngularJS/angular.min.js"></script>
 	<script src="yourPathToAngularSwaggerUI/dist/scripts/swagger-ui.min.js"></script>
 	<!-- if you choosed to use "ngSanitize" -->
 	<script src="yourPathToAngularSanitize/angular-sanitize.min.js"></script>
</body>

Add swagger-ui.min.css and bootstrap.min.css to the head of the HTML page.

<body>
	<head>
		...
		<link rel="stylesheet" href="yourPathToBootstrapCSS/bootstrap.min.css">
		<link rel="stylesheet" href="yourPathToAngularSwaggerUI/dist/css/swagger-ui.min.css">
  	</head>
</body>

Parameters

API explorer

Display or not API explorer, default is false

<div swagger-ui url="URLToYourOpenAPISpecification" api-explorer="true/false"></div>

OpenAPI specification loading indicator

yourScopeVariable will be assigned to true or false depending on OpenAPI specification loading status

<div ng-show="yourScopeVariable">loading ...</div>
<div swagger-ui url="URLToYourOpenAPISpecification" loading="yourScopeVariable"></div>

Error handler

Define an error handler to catch errors, if none defined console.error is used

<div swagger-ui url="URLToYourOpenAPISpecification" error-handler="yourErrorHandler"></div>

$scope.yourErrorHandler = function(/*String or Object*/ message, /*Integer*/ code){
	
}

Permalinks

Allows having a URL direct access to a group of operations or to an operation and making it unfolded at startup

<div swagger-ui url="URLToYourOpenAPISpecification" permalinks="true/false"></div>

Download

Display or not a link to download swagger file.

<!-- display link with url label -->
<div swagger-ui url="URLToYourOpenAPISpecification" download></div>

<!-- display link with specific key enter in swaggerTranslatorProvider -->
<div swagger-ui url="URLToYourOpenAPISpecification" download="downloadLabel"></div>

OpenAPI validator

Disable OpenAPI validator or define a custom OpenAPI validator. If parameter not defined, the validator will be 'http://online.swagger.io/validator'

<div swagger-ui url="URLToYourOpenAPISpecification" validator-url="false or URL"></div>

Parser type

OpenAPI specification parser is chosen depending on the Content-Type of the specification response. If host serving your OpenAPI specification does not send Content-Type: application/json then you can force the parser to JSON:

<div swagger-ui url="URLToYourOpenAPISpecification" parser="json"></div>

Template URL

Define a custom template to be used by OpenAPIUI

<div swagger-ui url="URLToYourOpenAPISpecification" template-url="yourTemplatePath"></div>

Inherited properties

Allows displaying inherited properties of polymorphic models

<div swagger-ui url="URLToYourOpenAPISpecification" show-inherited-properties="true/false"></div>

Input type and input

Render an OpenAPI specification from JSON object

<div swagger-ui input-type="json" input="yourJsonObject"></div>

Render an OpenAPI specification from YAML string

Make sure to use module swagger-yaml-parser, see Enable YAML

<div swagger-ui input-type="yaml" input="yourYamlString"></div>

Render an OpenAPI specification from URL (same behavior as using "url" parameter)

<div swagger-ui input-type="url" input="yourURL"></div>

i18n

Built-in languages

angular-swagger-ui is available in english and french, english is used by default

To use french, add fr.min.js at the end of the body

<body>
 	...
 	<script src="yourPathToAngularJS/angular.min.js"></script>
 	<script src="yourPathToAngularSwaggerUI/dist/scripts/swagger-ui.min.js"></script>
 	<script src="yourPathToAngularSwaggerUI/dist/scripts/i18/fr.min.js"></script>
</body>

Set language to french at startup

<script type="text/javascript">
	angular
		.module('yourApp', ['swaggerUi'])
		.config(function(swaggerTranslatorProvider) {
			swaggerTranslatorProvider.setLanguage('fr');
		});
	...
</script>

Set language to french at runtime

<script type="text/javascript">
	angular
		.module('yourApp', ['swaggerUi'])
		.controller('yourController', function(swaggerTranslator) {
			swaggerTranslator.useLanguage('fr');
		});
	...
</script>

Add languages

You can add your own languages, see src/scripts/i18n/en.js to find the keys you have to override

<script type="text/javascript">
	angular
		.module('yourApp', ['swaggerUi'])
		.config(function(swaggerTranslatorProvider) {
			swaggerTranslatorProvider.addTranslations('yourLangId', {
				key: 'value'
				...
			});
			swaggerTranslatorProvider.setLanguage('yourLangId');
		});
	...
</script>

Internationalize your app

You can also use swaggerTranslator to internationalize your app by using a service, a directive or a filter

<body>
 	...
 	<div swagger-translate="yourKey" swagger-translate-value="yourParam"></div>
 	<div ng-bind="yourDynamicKey|swaggerTranslate:yourDynamicParam"></div>
 	...
	<script type="text/javascript">
		angular
			.module('yourApp', ['swaggerUi'])
			.config(function(swaggerTranslatorProvider) {
				swaggerTranslatorProvider.addTranslations('en', {
					yourKey: 'blablabla {{propertyNameOfYourParam}}'
					...
				});
			})
			.controller('yourController', function(swaggerTranslator) {
				var localizedMessage = swaggerTranslator.translate('yourKey', yourParam);
			});
		...
	</script>
</body>

Writing your own modules

Modifying angular-swagger-ui can be achieved by writing your own modules. As an example your can have a look at the ones in src/scripts/modules. A module is an object (can be a service) having a function execute which must return a promise.

You can make your module modifying behaviours at different phases:

BEFORE_LOAD: allows modifying OpenAPI specification request before it is sent
BEFORE_PARSE: allows modifying OpenAPI specification after it has been loaded
PARSE: allows adding an OpenAPI parser for content types other than JSON
BEFORE_DISPLAY: allows modifying internal parsed OpenAPI specification before it is displayed
BEFORE_EXPLORER_LOAD: allows modifying API explorer request before it is sent
AFTER_EXPLORER_LOAD: allows modifying API explorer response before it is displayed

angular
	.module('myApp', ['swaggerUi'])
	.service('myModule', function($q) {

		this.execute = function(data) {
			var deferred = $q.defer();
			// if nothing done: call deferred.resolve(false);
			// if success: call deferred.resolve(true);
			// if error: call deferred.reject({message: 'error message', code: 'error_code'});
			return deferred.promise;
		}

	})
	.run(function(swaggerModules, myModule){
		// default priority is 1
		// higher is the priority, sooner the module is executed at the specified phase
		swaggerModules.add(swaggerModules.BEFORE_LOAD, myModule, priority);
	})
	...
