matcha

Matcha is an HTTP router designed for ease of use, power, and extensibility.

Features

• Flexible routing--handle your API specifications with ease
• Extensible components for edge cases and integration with 3rd-party tools
• High performance that scales to larger APIs
• Comprehensive and passing test coverage, and extensive benchmarks to track performance on key features
• Easy conversion from standard library; uses stdlib handler signatures and types
• Zero dependencies, zero dependency management

Installation

go get github.com/decentplatforms/matcha@v1.2.2

Basic Usage

Here's a "Hello, World" example to introduce you to Matcha's syntax! It serves requests to http://localhost:8080/hello.

package examples

import (
    "net/http"

    "github.com/decentplatforms/matcha/pkg/router"
)

func sayHello(w http.ResponseWriter, req *http.Request) {
    w.Write([]byte("Hello, World!"))
}

func HelloExample() {
    rt := router.Default()
    rt.HandleFunc(http.MethodGet, "/hello", sayHello)
    // or:
    // rt.Handle(http.MethodGet, "/hello", http.HandlerFunc(sayHello))
    http.ListenAndServe(":3000", rt)
}

Performance

Matcha has an extensive benchmark suite to help identify, document, and improve performance over time. Additionally, /bench contains a comprehensive benchmark API for "MockBoards", a fake website that just so happens to use all of the features of Matcha. The MockBoards API has the following:

• 18 distinct endpoints, including
  • 4 endpoints requiring authorization using a "client_id" header
  • 4 endpoints with an enumeration URI parameter (new/top posts, etc)
• 2 middleware components assigning a request ID and CORS headers
• 1 requirement for target host on all endpoints

The MockBoards benchmarks are run alongside an offset benchmark that measures the performance cost of setting up scaffolding for each request sent to calculate their final score. The values below represent performance numbers that you might expect to see in practice. Please keep in mind that performance varies by machine--you should run benchmarks on your own hardware to get a proper idea of how well Matcha's performance suits your needs.

MockBoards API Spec Benchmark

Benchmark	ns/request	B/request	allocs/request
Sequential	2226 ns/request	1909 bytes/request	27 allocs/request
Concurrent	1953 ns/request	1943 bytes/request	29 allocs/request

MockBoards Mounted API (v2) Benchmark

This mounts a copy of the API at /v2 and runs requests against both the v1 and v2 APIs.

Benchmark	ns/request	B/request	allocs/request
Sequential	2797 ns/request	2046 bytes/request	29 allocs/request
Concurrent	2097 ns/request	2139 bytes/request	30 allocs/request

MockBoards API Routing-Only Benchmark

This is the v1 spec, but with the non-path features stripped out to give a better idea of pure routing costs.

Benchmark	ns/request	B/request	allocs/request
Sequential	1054 ns/request	1417 bytes/request	12 allocs/request
Concurrent	1353 ns/request	1453 bytes/request	14 allocs/request
