Great for Microservices

Minimal APIs are great for building microservices for your applications fast.

C# Ecosystem

Minimal APIs is built using C#. An open-source, modern, object-oriented, and type-safe programming language you'll love. Build an API in C# with just 3 lines of code.

var app = WebApplication.Create(args);

app.MapGet("/", () => "Hello World!");

app.Run();

Routing

Minimal routes by design. Create meaningful low ceremony URLs that execute your code.

app.MapGet("/", () => "Hello World!");

Feels familiar

Minimal code patterns have been popular in JavaScript and Python web frameworks for a while. Whether you are familiar with Express or Flask, we think you can easily do things you enjoy about those frameworks with minimal APIs as well.

For example

Routes in Express

// GET method route
app.get('/', function (req, res) {
  res.send('GET request to the homepage')
})

// POST method route
app.post('/', function (req, res) {
  res.send('POST request to the homepage')
})

Routes in minimal APIs

app.MapGet("/", () => "GET request to the homepage");
app.MapPost("/", () => "POST request to the homepage");
