Swagger 2.X Getting started

It provides a number of tools for automatically generating documentation based on a given endpoint. Now when you make changes to your code, your documentation is updated and synchronized with the API so that consumers can quickly learn which resources are available, how to access them, and what to expect status code, content-type, etc. Test it out here. Then when you need to make changes to the API, you can just update the spec file. For this tutorial, we will be generating the Swagger spec based on the code from a previously created project that has the following RESTful endpoints:. Want to learn how this project was created? You should see:. To generate the Swagger specificationwe will be using swagger-jsdoc. Then add the following code to app. Take note of the comments above. This code essentially initializes swagger-jsdoc and adds the appropriate metadata to the Swagger specification. So, add such comments, in YAML, to the route handlers that describe their functionality. This should be fairly self-explanatory. For more information and examples, please see the Swagger Specification. Download the code from the repo.

Documenting Your Existing APIs: API Documentation Made Easy with OpenAPI & Swagger

You can add examples to parameters, properties and objects to make OpenAPI specification of your web service clearer. Examples can be read by tools and libraries that process your API in some way. For example, an API mocking tool can use sample values to generate mock requests. You can specify examples for objects, individual properties and operation parameters. To specify an example, you use the example or examples keys. See below for details. Note: Do not confuse example values with default values. An example illustrates what the value is supposed to be. A default value is what the server uses if the client does not provide the value. As you can see, each example has a distinct key name. Also, in the code above, we used an optional summary keys with description. Note: the sample values you specify should match the parameter data type. Note that in the code above, example is a child of schema. If schema refers to some object defined in the components section, then you should make example a child of the media type keyword:. If needed, you can use multiple examples:. Note: The examples in response and request bodies are free-form, but are expected to be compatible with the body schema. You can also specify examples for objects and individual properties in the components section. Note that schemas and properties support single example but not multiple examples. Note that arrays and array items support single example but not multiple examples. The URL should point to the resource that contains the literal example contents an object, file or image, for example :. Did not find what you were looking for? Ask the community Found a mistake?

Adding Examples You can add examples to parameters, properties and objects to make OpenAPI specification of your web service clearer. Parameter Examples Here is an example of a parameter value: parameters: - in: query name: status schema: type: string enum: [approved, pending, closed, new] example: approved Example of a parameter value Multiple examples for a parameter: parameters: - in: query name: limit schema: type: integer maximum: 50 examples: Multiple examples zero: Distinct name value: 0 Example value summary: A sample limit value Optional description max: Distinct name value: 50 Example value summary: A sample limit value Optional description As you can see, each example has a distinct key name. Object and Property Examples You can also specify examples for objects and individual properties in the components section. In property: components: schemas: User: Schema name type: object properties: id: type: integer format: int64 example: 1 Property example name: type: string example: New order Property example In object: components: schemas: User: Schema name type: object properties: id: type: integer name: type: string example: Object-level example id: 1 name: Jessica Smith Note that schemas and properties support single example but not multiple examples. Array Example You can add an example of an individual array item: components: schemas: ArrayOfInt: type: array items: type: integer format: int64 example: 1 or an array-level example containing multiple items: components: schemas: ArrayOfInt: type: array items: type: integer format: int64 example: [1, 2, 3] If the array contains objects, you can specify a multi-item example as follows: components: schemas: ArrayOfUsers: type: array items: type: object properties: id: type: integer name: type: string example: - id: 10 name: Jessica Smith - id: 20 name: Ron Stewart Note that arrays and array items support single example but not multiple examples.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I've set up a Unit Test to this endpoint, and it works perfectly. However, I do have one question. In Swagger, I'd like to show an example of the data object that will be returned. The only return type on the method is IHttpActionResult so I'm not surprised it's not showing the data model in Swagger. Note that since you have 2 exit points: one normal return with data and catch with that returns error message, I've defined in the example above two possible result types:. Swashbuckle Swagger infrastructure will read that and provide very rough examples of the data for these cases. However, if you need more detailed examples i. See here for details and quick tutorialin short:. The example provider works in a really simple way: whatever the provider returns, it is serialized to JSON and returned as the example for given data type. Just like that. Now, if your method returned DeliveryOptionsSearchModelprovider would use this data above directly. Or, if your method returned a larger object, composed of DeliveryOptionsSearchModel and few others, then Swagger would use this provider for one part of the response exaple, and other provider or default rough examples for all other parts of the large object. If you use 'normal' Net 4. In AspMvc for Net 4. That's OK for most of the times. However, if you really need to differentiate return types over response codes, or if you need to provide good examples, that's a problem. Some good people solved that already. See this article. It describes NuGet Swagger. ExamplesI believe it's for non-core, and it's targetted at providing better result descriptions. It also provides another attribute, [SwaggerResponseExample Core's IOperationFilter does not have schema registry as a parameter in the Apply method Implementation. How are we doing?

A Visual Guide to What's New in Swagger 3.0

Good user experience is key to using any product, and the same holds true for APIs. Since the advent of mobile and cloud computing, APIs have gone mainstream, with more and more companies and organizations understanding the business value of creating APIs. With a lot of web services emerging, the need to have clear API documentation for adopting these services became clear. API documentation is the information that is required to successfully consume and integrate with an API. This can be in the form of technical writing, code samples and examples for better understanding how to consume an API. Concise and clear documentation — which allows your API consumers to adopt it into their application quickly — is no longer optional for organizations that want to drive adoption of their APIs. Good documentation accelerates development and consumption, and reduces the money and time that would otherwise be spent answering support calls. Documentation is part of the overall user experience, and is one of the biggest factors for increased API growth and usage. APIs, like so many other products, tend to evolve rapidly during development and release cycles. Maintaining and updating this documentation for your development team and end consumers, so they work with the API efficiently, becomes a difficult process. The second issue is facilitating interaction between multiple web services. Applications are made up of multiple services that constantly communicate and interact with each other. As RESTful services grow in number, so do the programming languages that are used to implement them, making it harder for them to communicate. API documentation can be thought of as the interface for consuming an API, and such, needs to facilitate interaction between these different web services. Regular API interfaces, be it text documentation, or others like Javadocs, do not allow them to communicate with each other. These challenges, along with other API pain points, led to the creation of the Swagger Specification. This is meant to reference the Specification. This contract is language agnostic and human readable, allowing both machines and humans to parse and understand what the API is supposed to do. Other benefits include:. This is a relatively new approach, but is fast catching on, especially with the use of OpenAPI. Spotting issues in the design, before writing any code is a much more efficient and streamlined approach than doing so after the implementation is already in place. Here are some resources to help you get started in the process:. The Code First approach also commonly known as the "bottoms up" approach is a more traditional approach to building APIs, with development of code happening after the business requirements are laid out, then the documentation of the API is done from the code. Swagger Inspector is an easy to use developer tool to quickly execute any API request, validate its responses and generate a corresponding OpenAPI definition. After you perform your first call, you can create a free account and save your call history within Inspector. With Swagger Inspector, you can automatically generate the OpenAPI file for any end point you call, saving valuable development time, and allowing your technical writers to get started on creating great documentation. The integration allows developers to automatically host and visualize their API documentation on SwaggerHub to enable API discovery and consumption by internal and external stakeholders. Head over to Swagger Inspectorand insert the end point of the resource you want to have documented. The cool thing about Inspector is that you can select multiple end points and consolidate their documentation in one single OpenAPI file through a Collection. If you already have a SwaggerHub account, then you can log into Swagger Inspector with your credentials. When you create a Swagger Inspector account, you automatically join the SwaggerHub family. After you create an account, you can easily access all your tests in your history, anywhere at any time, and also generate the corresponding OpenAPI specification with the click of a button in Inspector. With the definition in place, you can add in important details like: supported content types, descriptions, examples, authentication types, and more. Swagger-core is the Java implementation of Swagger. This meta-data will generate the contract, client-side code, and other artifacts during runtime.

Implement Swagger UI With Web API

It is a public interface, which other modules, applications or developers can use. Even if you're not publicly exposing it, it is still important. Backend and frontend code is usually worked on by different developers. The one who is creating the API is usually not the one who is consuming it. It is, therefore, crucial to have properly documented interface to avoid confusion and keep it always up to date. What's more, from that UI you can not only browse information about your API endpoint, but you can use the UI as a REST client - you can call any of your endpoints, specify the data to be sent and inspect the response. It's quite handy. It is however not realistic to write such documentation by hand and keep it updated whenever your code changes. This is where SpringFox comes into play. It is a Swagger integration for Spring Framework. It can automatically inspect your classes, detect Controllers, their methods, model classes they use and URLs to which they are mapped. Without any handwritten documentation, it can generate a lot of information about your API just by inspecting classes in your application. How cool is that? Most importantly, whenever you make changes they'll be reflected in the documentation. To start, you'll need a Spring Boot application with some Rest Controllers, I've prepared a simple one here. For this article, I used SpringFox 2. It uses version 2 of the Swagger specification. The support should be available in the next version. The source code of final project built with all the features described in this blog post is available on GitHub. To work with SpringFox in your project, you need to add it as a dependency first. If you are using Maven, you can use the following you can check whether a newer version is available. After adding the dependency, you'll need to provide some basic Spring configuration. While you can technically use one of your existing configuration files, it is better to have a separate file for it. The first thing you'll need to provide is a EnableSwagger2 annotation. Then you need to provide a Docket bean, which is the main bean used to configure SpringFox. Of course, you can provide many more configuration settings as we'll see later, but this is a minimalistic configuration, which does the following:. If you deploy your application now, swagger metadata describing your API is already being generated! You can check it out:. Turns out it is just a big JSON, not very human readable. But you can already verify it works. Paste your generated JSON to the left panel and voila! You can now see your generated documentation as HTML page. Nice, isn't it?
