You've created a Swagger UI docs page, and you're set to start writing docs. Step 2: Define your API's root information You now have the start of a beautiful docs page for your API! The rest of this tutorial provides a basic introduction to OpenAPI definitions. Since we have no other definitions yet, you'll see a "No operations defined in spec!" message: You'll see the title and version number of your Express API, as well as the OpenAPI version number ( 3.0.0). Restart the Express server, and navigate to localhost:3000/docs in the browser. Then, add an endpoint path called /docs (or any name of your choosing):Īs shown above, swagger-ui-express provides two callbacks to set up the endpoint: one to set up Swagger UI with the swaggerSpec definitions and one to serve it to the /docs endpoint. To create a Swagger UI page for your Express API, include swagger-ui-express in the app.js file. If you get any errors at this stage, check that your swagger-jsdoc version is 5.0.1 exactly. Restart the Express server to ensure there are no errors.

You'll pass this object to Swagger UI in the next step. This specification is equivalent to the swagger.json or swagger.yaml file normally used by Swagger UI to create a docs page. The options object is used by swagger-jsdoc to produce an OpenAPI specification in a variable called swaggerSpec. You can list the filenames individually or use the wildcard delimiter * to add all JavaScript files in a directory, as shown above. In our case, definitions will be written in JSDoc directly in the /routes files. These file paths should be relative to the root directory of your Express API. These are paths to files containing other OpenAPI definitions. The options object contains this swaggerDefinition object and an array of paths called apis.

Provide a few basic pieces of information to the swaggerDefinition, such as the title and version of your API you can fill in more later. The swaggerDefinition object (i.e., the OpenAPI definition) defines the root information for your API.

The full URL used to retrieve data from the API is formed by adding the endpoint to the base URL: localhost:3000/users.ġ.1: Install swagger-jsdoc and swagger-ui-express Represented by a database model in Express.

You can then write JSDoc comments in your API's source code to generate the OpenAPI definitions. In this tutorial, you will set up a Swagger UI documentation web page for an Express API. As this tutorial will show, these definitions can be written in YAML directly in JSDoc comments. Swagger UI creates a web page from OpenAPI Specification definitions. Swagger provides a tool for presenting this documentation: Swagger UI. Second, the comments can be compiled later into a complete set of reference documentation.

First, the documentation is directly available to anyone viewing the source code. JSDoc is a popular tool for generating documentation from comments in the source code of your app.
