Benchmarks

The following benchmarks were conducted to measure the performance of various functions in the github.com/mrz1836/go-parameters package. All tests were run on a machine with the following specifications:

• Operating System: macOS (Darwin)
• Architecture: ARM64
• CPU: Apple M1 Max

Benchmark Results

Benchmark Details

• UniqueUint64: Measures the performance of generating unique uint64 values.
• GetParams_ParseJSONBody: Benchmarks parsing a JSON body into parameters.
• GetParams: Tests retrieving parameters without parsing.
• Params_GetStringOk: Evaluates fetching a string parameter with success indication.
• Params_GetBoolOk: Assesses fetching a boolean parameter with success indication.
• Params_GetBytesOk: Measures retrieving a byte slice parameter with success indication.
• Params_GetBool: Benchmarks fetching a boolean parameter without success indication.
• Params_GetFloatOk: Tests fetching a float parameter with success indication.
• Params_GetIntOk: Evaluates fetching an integer parameter with success indication.
• Params_GetInt64Ok: Measures fetching a 64-bit integer parameter with success indication.
• Params_GetIntSliceOk: Benchmarks retrieving a slice of integers with success indication.
• Params_GetUint64Ok: Tests fetching an unsigned 64-bit integer parameter with success indication.

Benchmark Notes

• Iterations: The number of times the benchmark function was executed.
• ns/op: Nanoseconds per operation, indicating the average time taken for each operation.
• B/op: Bytes allocated per operation, showing the memory usage.
• allocs/op: Allocations per operation, indicating how many memory allocations occurred per operation.

Basic implementation:

package main

import (
    "fmt"
	"log"
	"net/http"

	"github.com/julienschmidt/httprouter"
	"github.com/mrz1836/go-parameters"
)

func Hello(w http.ResponseWriter, req *http.Request) {

	params := parameters.GetParams(req)

	name, _ := params.GetStringOk("name")

	_, _ = fmt.Fprintf(w, `{"hello":"%s"}`, name)
}

func main() {
    router := httprouter.New()
	router.GET("/hello/:name", parameters.GeneralJSONResponse(Hello))
	log.Fatal(http.ListenAndServe(":8080", router))
}
