	AllowOrigins     []string
	AllowMethods     []string
	AllowHeaders     []string
	ExposeHeaders    []string
	AllowCredentials bool
	MaxAge           int

Compare: Node.js · Standard Go · gox

Node.js

// Typical express, cors, helmet, morgan pattern in Node.js

Standard Go

func handler(w http.ResponseWriter, r *http.Request) {
    // chi or net/http
}

gox

import "github.com/sahilkhaire/gox/http"

app := New()
app.Use(CORS(CORSOptions{AllowOrigins: []string{"https://app.example"}}))
app.Get("/", func(c *Ctx) error { return c.Status(204).JSON(204, nil) })
req := httptest.NewRequest(http.MethodOptions, "/", nil)
req.Header.Set("Origin", "https://app.example")
rec := httptest.NewRecorder()

Example

import "github.com/sahilkhaire/gox/http"

app := New()
app.Use(CORS(CORSOptions{AllowOrigins: []string{"https://app.example"}}))
app.Get("/", func(c *Ctx) error { return c.Status(204).JSON(204, nil) })
req := httptest.NewRequest(http.MethodOptions, "/", nil)
req.Header.Set("Origin", "https://app.example")
rec := httptest.NewRecorder()

Tips

Stack Logger, Recover, and Security middleware the way you would morgan + helmet in Express.

Standard library alternative

Use the standard library directly:

func handler(w http.ResponseWriter, r *http.Request) {
    // chi or net/http
}
