APIs are like restaurants. 🍴
Your menu = Endpoints
Your dishes = Data/Services
Your customers = Other apps

But how do customers know what to order?
👉 That’s where 𝗡𝗦𝘄𝗮𝗴 steps in.

What is NSwag?

• A tool for .NET & ASP.NET Core APIs
• Creates documentation automatically
• Gives you an interactive UI to test APIs
• Generates client code (C#, TypeScript) so others can call your API easily

Think of it as a Swiss army knife 🔪 for API developers.

Books API Example 📚

Endpoints:

• GET /books → Get all books
• GET /books/{id} → Get book by ID
• POST /books → Add a new book

With NSwag, you get:
✔️ Swagger UI to test requests
✔️ Ready-made C# client methods like:

var books = await todoClient.GetAsync();
await todoClient.CreateAsync(new Book { Title = "New Book" });

No manual HTTP coding needed. 🚀

Advantages:

• Auto-generates OpenAPI/Swagger spec
• Serves Swagger UI & Redoc
• Produces client code (C#, TS)
• Easy to customize & document

Note: Use [ProducesResponseType] and XML comments so your API docs are always clear and accurate.

👉 Have you used NSwag before, or are you still writing HTTP requests manually?
