Comment 0. What is any developer's favorite activity? Coding, of course. However, if a developer does nothing but write code, the situation starts looking pretty sad.

In order to achieve optimal results, software engineers need to communicate with each other. In the software development process, documentation is one of the best ways you can support such communication.

One of the best examples of documentation - improving the lives of front-end and backend developers as well as testers - comes from Swagger.

The platform's features include descriptions of input and output models, request parameters, the ability to change environments, and implication and expansion of models. However, as Benjen Stark once said, "You know, my brother once told me that nothing someone says before the word 'BUT' really counts.

Swagger and Node. The first method is to use the swagger-node module. This module is really easy to work with:. However, this method has one significant disadvantage. In non-experimental, real-life situations, information required to create documentation input and output parameters and filters must be described by the controller, making its code incredibly heavy, hard to read, and difficult to understand.

Accordingly, this isn't the best method for a serious project. The second method - a method more applicable to large-scale projects - is Swagger UI.

How to Bring Swagger and Node.js Together

It can be used as a module of an existing application, or launched in a separate Docker container:. To create the Docker container, you can use a readymade image, launching the container and indicating the path to the documentation file.

I recommend using a different approach, however - one which allows more precise adjusting and tuning:. At this point, you understand that you need to have a united configuration file. However, working with a giant file that contains the entire project's documentation is a highly uncomfortable experience. The only way to work with any project bigger than "Hello, World!

There are two ways to divide documentation into modules: You can use third-party libraries, or you can solve the problem on your own. The most popular library makes it possible to use the internal reference tool.

This is obviously comfortable. However, this approach limits you with the links to the description of the models within the same file. You may think that other proprietary solutions will be less sophisticated, but let's not jump to conclusions. Swagger documentation consists of several big sections described in JSON format:. After looking at this kind of representation, you may conclude that one of the most convenient ways to collect documentation from files is via simple concatenation.

In this approach, you describe each model and path in the file. The documentation generator can be also divided into several logical parts. The first one is preparatory: You are going to connect all required libraries and a "header" for Swagger documentation.

The next important part is a function that will open the path sent as an argument, read the list of the files, process them, and combine them in the final documentation file.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I followed instructions to set up swagger documentation for my existing node API using swagger-jsdoc. The swagger. It actually fails to do so because I'm serving the page through https and the petstore is not https but that's a different matter Inputing my address to the swagger.

It shows the API page correctly and validates it. However, I don't want to always re-enter the address there and would like to have it as a default.

Swagger UI 3. I had been having this issue lately when deploying using docker. Tried everything from changing all instance of petstore to my own api json docs but to no avail. Took me two days but it was great to see it finally working. Learn more. Swagger-ui keeps showing example petstore instead of provided swagger. Asked 2 years, 11 months ago. Active 1 month ago.

Community and Moderator guidelines for escalating issues via new response….It provides a powerful and actively developed ecosystem of tools around this formal specification like code generators and editors. The best part of Swagger is that the documentation of methods, parameters, and models are tightly integrated into the server code, allowing APIs to always stay in sync.

And so we make the swagger. The online editor can be used for creating the file. In this section, we will install swagger, setup the swagger UI and generate server side and client SDK using it. For installing swagger using Node package manager execute the following command:. Use of '-g' flag will ensure the module is installed globally. Next, we will create a project using the following command:. Express can be selected for the same. The server is basically ready now and can be started using this command to be executed in project root:.

If the host server is set as localhost and port number is not modified in app. This can be started in a new terminal using:. This will open up the swagger editor in a browser tab on a randomly generated port. A sample hello GET request can be seen already present in the swagger. Any further change to this file will cause the server to restart on its own. In the paths section, the value used for x-swagger-router-controller should be the javascript file name in controllers folder.

Also, the value for operationId parameter represents the function name in the above javascript file. This is where business logic should be written. Thus, our swagger setup is complete and can be used to further develop our API. Download swagger PDF swagger Getting started with swagger springfox swagger-ui. The above can be done during maven build during swagger maven plugin. Installation and Setup In this section, we will install swagger, setup the swagger UI and generate server side and client SDK using it.

Previous Next. Related Tags ASP.So it happened I started this project with friend of mine, a new app to launch on the mobile market. I offered to write the server-side, a simple web API. Once he got my code he immediately asked me "Sam how do I know the routes and so on?! Write a documentation or something! And then Swagger came up.

Swagger and NodeJS

I presume many of you encountered this situation before or will in the future, a developer may write the best web API service but without proper documentation how can other developers discover and use it? One feature I like is the mock mode, which allows developers to design routes without writing a single line of code in javascript.

This is the approach I am going to follow in this tutorial: We first focus on the design and then on the code. You can directly clone the app repository from my Github here. As said before Swagger is supported in node.

The prompt asks for the framework we want to use, choose express. Once completed, let's take a look at the project directory:. Not original at all, I give you that, but as we are beginners it is good see Swagger in action and get insight on how it works. In order to run the example I have to introduce Swagger editor. Swagger editor is an elegant browser-based editor which really simplifies our efforts to develop a web API.

In particular, it provides:. The picture above shows you the UI of the Swagger editor of our app. On the left you can see the yaml file we are going to edit swagger. By clicking on any of them we can have a good understanding of the parameter required, the format of request and responses, more generally a description of the route.

Wiring up an API server with Express and Swagger

If everything went well the editor should open a new tab in your browser. We are asked to enter a paramenter name : Go for it and test the route. Here is my result:. The parameter name is the only one and you may see that it is in the path, it is not required and it is a string.

We can define a different response for each situation, given the http status or errors, a particular response can be defined. Why is that?This module allows you to serve auto-generated swagger-ui generated API docs from express, based on a swagger. Swagger version is pulled from npm module swagger-ui-dist. Please use a lock file or specify the version of swagger-ui-dist you want to ensure it is consistent across environments. If you want to set up routing based on the swagger document checkout swagger-express-router.

By default the Swagger Explorer bar is hidden, to display it pass true as the 'explorer' property of the options to the setup function:. To pass custom options e. For all the available options, refer to Swagger UI Configuration. To customize the style of the swagger page, you can pass custom CSS as the 'customCss' property of the options to the setup function.

You can also pass the url to a custom css file, the value must be the public url of the file and can be relative or absolute to the swagger path. If you would like to have full control over your HTML you can provide your own javascript file, value accepts absolute or relative path.

Value must be the public url of the js file. To load your swagger from a url instead of injecting the document, pass null as the first parameter, and pass the relative or absolute URL as the 'url' property to 'swaggerOptions' in the setup function. To load multiple swagger documents from urls as a dropdown in the explorer bar, pass an array of object with name and url to 'urls' property to 'swaggerOptions' in the setup function.

Make sure 'explorer' option is set to 'true' in your setup options for the dropdown to be visible. To load your swagger specification yaml file you need to use a module able to convert yaml to json; for instance yamljs. To dynamically set the host, or any other content, in the swagger file based on the incoming request object you may pass the json via the req object; to achieve this just do not pass the the swagger json to the setup function and it will look for swaggerDoc in the req object.

The following is a simple API defined with Swagger in a file my-api. Define an async function to create and configure the Express app itself. This will use the swagger-parser library to parse our swagger api YAML file hence the need to be async and pass the parsed info to swaggerRouter to configure it. Most APIs need to add some level of authentication and access control to specific routes.

In the Swagger document you can add security information on a path-by-path basis. You need to tell the swaggerRouter how to associate the security scopes defined in the document with actual authentication middleware. Now in our makeApp function we need to pass in some options to swaggerRouter. Now the connect function will know to associate paths with the scopes identity.

Add Swagger-UI To Existing NodeJS TypeScript API

The swaggerRouter understands that the ping route is not to go under the basePath because of the root tag. You can change this in the options outlined below.

If the Swagger doc defines an operationId that cannot be mapped to an existing route controller function then the connector will insert a default notImplemented function in its place that returns res. If no operationId is associated with a path then the connector will insert a default notFound function that returns res. You can override the default functions via options passed to swaggerRouter as outlined below. The full set of allowed options for the swaggerRouter function is:.

The swagger-express-validator validates the inputs and outputs of your API route controllers against their Swagger definitions. When combined with comprehensive integration tests you assert the correctness of your server. Sign in. Dave Sag Follow. Some rights reserved. See responses 2.
