??Fundamentals of API development with Swagger and OpenAPI.

APIs (Application Programming Interfaces) are the backbone of modern applications. Today the article on the Backend API development workflow, dive into best practices for API design, and learn how to leverage Swagger and OpenAPI Specification (OAS) for seamless documentation and testing.

?? Workflow of API Development of Server :

1. Make or Define API Requirements ??
2. Design API Endpoints ??
3. Model Data and Relationships ???
4. Write the API Specification ??
5. Develop the API ???
6. Test the API ?
7. Document the API ??
8. Deploy and Scale ??

??? Best Practices for Scalable API Design:

1. Consistency is Key ??
2. Versioning Your API ??
3. Use Pagination and Filtering ??
4. Authentication and Authorization ??
5. Rate Limiting and Throttling ?
6. Error Handling and Responses ?

?? Resources and Collections for API Design and Development

• OpenAPI Specification (OAS) ???
• Swagger Documentation ??
• Postman ??
• API Design Tools ??

Now I will discuss shortly about the popular open-source framework Swagger. That allows you to design, build, document, and test your APIs with the help of OpenAPI Specification (OAS).

Features of Swagger are API Documentation, API Testing, Standardization, Interactive Documentation, and Automated Code Generation.

Integrate Swagger into your Simple Node.js and Express backend with TypeScript in an MVC architecture.

1. Install and make swagger API docs config :::

2. Now write your swagger title, summary, and response on your routes :::

3. Now hit on the 'your-server-URL/api-docs'. It will show the docs in browser :::

Whether you’re building an API for a project or scaling to millions of users, thoughtful design, proper documentation, and testing are crucial. Leverage the power of Swagger and OpenAPI to streamline your API workflow and enhance your development experience!
