MapX
Lightweight helpers for working with Go maps (and structs) in a type-safe way.
Features
- Basic operations –
Get,Set,Has,Count,Copy,Merge - Typed accessors –
GetString,GetBool,GetInt,GetFloat64,GetStrings,GetAnySlice,GetMap - Default helpers –
GetXXXDefault(string, bool, int, float64, slice, map, any) - Object helpers –
Keysextracts field names from maps or structs via reflection - Conversion –
ToGenericconverts any map tomap[any]any
Quick Start
package main
import (
"fmt"
"github.com/kaptinlin/gozod/pkg/mapx"
)
func main() {
cfg := map[string]any{
"app": "demo",
"port": 3000,
}
// Read values safely
app, _ := mapx.GetString(cfg, "app") // "demo"
port := mapx.GetIntDefault(cfg, "port", 80)
// Write values
mapx.Set(cfg, "debug", true)
// Copy & merge
clone := mapx.Copy(cfg)
merged := mapx.Merge(cfg, map[string]any{"port": 8080})
fmt.Println(app, port, clone, merged)
}
