OneOfOne/jsonex

jsonex: A simple fork of encoding/json

This package is a fork of encoding/json that allows decoding individual JSON slice and map items. It is intended to be used in conjunction with jsonex.Decoder to allow decoding of large JSON files without loading the entire file into memory.

It adds 2 functions DecodeKey and DecodeValue that allow decoding of individual JSON slice and map items.

Synced with Go on 2023-04-19.

Example

	package main

	import (
		"fmt"
		"strings"

		"go.oneofone.dev/jsonex"
	)

	func main() {
		dec := jsonex.NewDecoder(strings.NewReader(`{"foo": "bar", "baz": "qux"}`))

		// Decode the first key
		key, err := dec.DecodeKey()
		if err != nil {
			panic(err)
		}
		fmt.Println(key)

		// Decode the first value
		var value string
		err = dec.DecodeValue(&value)
		if err != nil {
			panic(err)
		}
		fmt.Println(value)

		// Decode the second key
		key, err = dec.DecodeKey()
		if err != nil {
			panic(err)
		}
		fmt.Println(key)

		// Decode the second value
		err = dec.DecodeValue(&value)
		if err != nil {
			panic(err)
		}
		fmt.Println(value)
	}
