jsoniter (json-iterator) is fast and flexible JSON parser available in Java and Go

• Jsoniter is the fastest JSON parser. It could be up to 10x faster than normal parser, data binding included. Shameless self benchmark
• Extremely flexible api. You can mix and match three different styles: bind-api, any-api or iterator-api. Checkout your api choices
• Unique iterator api can iterate through JSON directly, zero memory allocation! See how iterator works

Here is a quick show off, for more complete report you can checkout the full benchmark with in-depth optimization to back the numbers up

Bind-api should always be the first choice. Given this JSON document [0,1,2,3]

Parse with Go bind-api

import "github.com/json-iterator/go" iter := jsoniter.ParseString(`[0,1,2,3]`) var := iter.Read() fmt.Println(val)

When you do not need to get all the data back, just extract some.

Parse with Go iterator-api

import "github.com/json-iterator/go" iter := ParseString(`[0, [1, 2], [3, 4], 5]`) count := 0 for iter.ReadArray() { iter.Skip() count++ } fmt.Println(count) // 4

Parse with Go any-api

import "github.com/json-iterator/go" iter := jsoniter.ParseString(`[{"field1":"11","field2":"12"},{"field1":"21","field2":"22"}]`) val := iter.ReadAny() fmt.Println(val.ToInt(1, "field2")) // 22

Notice you can extract from nested data structure, and convert any type to the type to you want.
