This package generates a nodejs, reactjs or angularjs class from a swagger specification file. The code is generated using mustache templates and is quality checked by jshint and beautified by js-beautify. It provides a lot of decorators to write your code. This is the new version of swagger-js, 3. The new version supports Swagger 2. This package is a wrapper of Swagger-php and swagger-ui adapted to work with Laravel 5.

In order to generate the Swagger documentation for your API, Swagger offers a set of annotations to declare and manipulate the output. These annotations can be added in your controller, model or even a seperate file. An example of annotations can be found here.

Hello, nest!

Refer to the 2. Valid Swagger JSON descriptions can then be generated and used with the full Swagger tooling code generation, documentation, etc. The swagger module provides tools for designing and building Swagger-compliant APIs entirely in Node.

It integrates with popular Node. With swagger, you can specify, build, and test your API from the very beginning, on your laptop. It allows you to change and iterate your design without rewriting the logic of your implementation. Remember, one great thing about this approach is that all of the Swagger validation logic is handled for you, and all of the routing logic is managed through the Swagger configuration. You don't have to code or recode! Release Notes for v9. Note: For hapi versions below v17, you must use versions v7.

It also provides a simple framework to add additional converters from different formats into the Swagger objects, making the entire toolchain available. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swagger removes the guesswork in calling the service.

Check out Swagger-Spec for additional information about the Swagger project, including additional libraries with support for SpringMVC, other languages and more. The output of Swagger2Markup can be used as an alternative to swagger-ui and can be served as static content.Go to Solution. I've found it very convenient to use Visual Studio to make any additional changes you need.

The last one links to Swagger references in the last reply that might be of help. It seems to me, as a beginner, there is quite a bit to learn about Swagger and creating an API connection.

The PA Team has been very helpful in my learning process but it has taken me a longer time than I first thought it would. View solution in original post.

I thought I should mention one other thing. ExCessnait looks like we're building similar apps--your posts show that you're building an ISBN lookup.

What is your lookup source? Yes, we're both doing ISBN lookups. I've tried three different sources: ISBNdb. All provide good information and are free. I may try Google Books as well. While connections have been established, I still don't have any of them returning to PowerApps the response I see in the Swagger Editor.

But I do see evidence that the connection is made, as I can create DataSource statements that include the fields returned. An "Internal Server Error" has been the problem with two of them. The PA Team has been very responsive to the issue and has been very helpful, so hopefully it will be resolved soon.

Each operation must have at least one response defined, usually a successful response. JSON is the most common format for data exchange, but not the only one possible.

To specify the response media types, use the produces keyword on the root level or operation level. The global list can be overridden on the operation level.

An operation typically returns one successful status code and one or more error statuses. Each response status requires a description. For example, you can describe the conditions for error responses. GitHub Flavored Markdown can be used for rich text representation. User ID must be an integer and bigger than 0.

Note that an API specification does not necessarily need to cover all possible HTTP response codes, since they may not be known in advance.

However, it is expected to cover successful responses and any known errors. By "known errors" we mean, for example, a Not Found response for an operation that returns a resource by ID, or a Bad Request response in case of invalid operation parameters.

Response Body The schema keyword is used to describe the response body. Schema can be defined inline in the operation: responses: description: A User object schema: type: object properties: id: type: integer description: The user ID. This is useful if multiple responses use the same schema.

In this case, define the response schema with type: file and specify the appropriate MIME types in the produces section. To indicate the response body is empty, do not specify a schema for the response. Swagger treats no schema as a response without a body.One of the other names for that would be monorepo. The reasons for that would be multiple :. Also, Nx uses great modern tools like Cypress for e2e testing and Jest for unit test, and I love that. You actually have many options to create the project, have an empty project and then add a frontend with Angular and a backend with NestJS.

The installer will prompt you anyway for common stacks :.

But if you test the route, it will fail, since there is no decorator for any HTTP method. Now all the routes should be active and we could test them with whatever way, postman for example.

Note that the controllers will be enhanced later with all NestJS tools, like middlewares, exceptions, filters …. You can track precisely any route or all routes, and check how the server is called. This is it for the configuration, now we need an Angular service that implements NgRx Data, for example, EntityCollection :.

The final app will have a few components to list the Todos and make simple operations. Just like the original app I made. We will simply add bootstrap 4 and fontawesome with angular-fontawesome, elegant way to load only needed icons.

Ramsatt Learn More Code Easy.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 :.

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.

SwaggerHub Swagger Inspector.The larger your application gets, the hard it is to maintain your codebase because of all of the possible configurations. Luckily, there is a framework called NestJS that takes many of the conventions of Angular, places them on top of Express JS and uses them to create a more consistently designed application architecture.

Many of the benefits include consistent ways of handling documentation using swagger, type checking and dependency injection with Typescript and compatibility with the majority of all Express middleware. This makes it easier to create the different components needed for NestJS. We will also want to remove the AppController and AppService files because we will not be using them.

Now we must create our mongoose database schema and register it with our module. Create an interfaces folder with an itodos. The todos. In our case, there are MongoDB documents created using Mongoose. Then in the index. We will also create a createTodo. The best way to do this is to create a service that allows for us to call reusable database queries that can be passed around our application. This way, we can take a class and place an instance of it to be used inside of another class.

Inside of out TodosService, import mongoose as well as your models and service interfaces. Also, make sure to the to modules that allow for dependency injection in your Service class. Next, make your service class injectable with the Injectable decorator, add the interface to service to make sure all of the queries conform to the basic crud functions and inject our iTodo interface.

Now we can create our route that map to our TodosService, Each decorator annotates what type of request is being made and the URL path. This registers all of our controllers and services inside of our TodosModule with our main AppModule. Once everything is finished, you can now run you app with. It offers a consistent structure, type-checking easier integration with express middleware. James Coonce is a programmer from Tampa Fl that has a love for golf, travel and language learning.
