Introduction

jsonpointer-go is a Go library for working with JSON Pointers as defined in RFC 6901. JSON Pointers provide a way to reference specific parts of a JSON document.

Installation

To install the library, simply run:

go get github.com/bragdond/jsonpointer-go

Usage

Here is a simple example of how to use jsonpointer-go:

package main

import (
    "fmt"
    "github.com/bragdond/jsonpointer-go"
)

func main() {   
	jsonStr := `{
        "foo": ["bar", "baz"],
        "qux": {"corge": "grault"}
    }`

    var jsonData map[string]any
    if err := json.Unmarshal([]byte(jsonStr), &jsonData); err != nil {
        panic(fmt.Sprintf("failed to unmarshal json string: %v", err))
    }

    pointer, err := jsonpointer.Parse("/foo/0")
    if err != nil {
        panic(err)
    }

    result, err := pointer.GetValue(jsonData)
    if err != nil {
        panic(err)
    }

    fmt.Println(result) // Output: bar
}
