Swagger UI keeps showing Swagger Petstore? Here’s What You Need to Know!

Are you tired of seeing the Swagger Petstore example every time you open your Swagger UI? Do you want to get rid of it and start exploring your own APIs? You’re in the right place! In this article, we’ll delve into the world of Swagger UI and explore why it keeps showing the Swagger Petstore example. More importantly, we’ll provide you with step-by-step instructions on how to change it and start using your own APIs.

What is Swagger UI?

Swagger UI is a popular open-source tool that allows developers to visualize and interact with RESTful web services. It provides a graphical interface to browse, read, and write APIs, making it easier to understand and test API definitions. Swagger UI is built on top of the OpenAPI Specification (OAS), which is an industry-standard for describing RESTful APIs.

What is the Swagger Petstore?

The Swagger Petstore is a sample API definition provided by Swagger UI to demonstrate its capabilities. It’s a simple API that allows users to manage pets, including creating, reading, updating, and deleting pet information. The Petstore example is embedded in Swagger UI by default, which is why you see it every time you open the tool.

Why does Swagger UI keep showing the Swagger Petstore?

There are several reasons why Swagger UI might keep showing the Swagger Petstore example:

• Lack of configuration: If you haven’t provided Swagger UI with a custom API definition, it will default to the Petstore example.
• Incorrect API definition: If your API definition is incorrect or incomplete, Swagger UI might fall back to the Petstore example.
• Missing or incorrect URL: If the URL to your API definition is incorrect or missing, Swagger UI will default to the Petstore example.

How to change the default API definition in Swagger UI

To change the default API definition in Swagger UI, you need to provide it with a custom API definition file. Here are the steps to follow:

1. Step 1: Create an OpenAPI definition file

         Create a new file with a .yaml or .json extension (e.g., api-definition.yaml or api-definition.json). This file will contain your API definition in OpenAPI format.
       

2. Step 2: Define your API

         In your OpenAPI definition file, define your API using the OpenAPI syntax. For example:
         
           openapi: 3.0.2
           info:
             title: My API
             description: My API description
             version: 1.0.0
           paths:
             /pets:
               get:
                 summary: Get all pets
                 responses:
                   200:
                     description: List of pets
                     content:
                       application/json:
                         schema:
                           type: array
                           items:
                             $ref: '#/components/schemas/Pet'
           components:
             schemas:
               Pet:
                 type: object
                 properties:
                   id:
                     type: integer
                   name:
                     type: string
                 required:
                   - id
                   - name
         
       

3. Step 3: Configure Swagger UI

         Update your Swagger UI configuration to point to your custom API definition file. For example, if you're using Swagger UI in a Node.js application, you can update your swagger-ui.js file as follows:
         
           const SwaggerUI = require('swagger-ui');
           const apiDefinition = './api-definition.yaml';
           SwaggerUI({
             dom_id: '#swagger-ui',
             url: apiDefinition,
           });
         
       

Troubleshooting common issues

If you’re still having issues with Swagger UI showing the Petstore example, here are some common mistakes to check:

Error	Solution
Invalid API definition	Check your OpenAPI definition file for syntax errors or inconsistencies. Use a tool like Swagger Editor to validate your API definition.
Incorrect file path or URL	Double-check the file path or URL to your API definition. Make sure it’s correct and accessible.
Swagger UI not updated	Clear your browser cache and restart Swagger UI. If you’re using a Node.js application, restart the server.

Conclusion

In conclusion, Swagger UI keeps showing the Swagger Petstore example because it’s the default API definition provided by the tool. By creating a custom API definition file and configuring Swagger UI to point to it, you can change the default API definition and start exploring your own APIs. Remember to troubleshoot common issues and validate your API definition to ensure a smooth experience.

With these instructions, you should be able to get rid of the Petstore example and start using Swagger UI with your own APIs. Happy coding!
