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

Why jsoniter?

  • 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

1 Minute Tutorial

Given this JSON document [0,1,2,3]

Parse with Java bind-api

import com.jsoniter.Jsoniter;
Jsoniter iter = Jsoniter.parse("[0,1,2,3]");
int[] val = iter.read(int[].class);
System.out.println(val[3]);

Parse with Java any-api

import com.jsoniter.Jsoniter;
Jsoniter iter = Jsoniter.parse("[0,1,2,3]");
Any val = iter.readAny();
System.out.println(any.get(3));

Parse with Java iterator-api

import com.jsoniter.Jsoniter;
Jsoniter iter = Jsoniter.parse("[0,1,2,3]");
int total = 0;
while(iter.readArray()) {
    total += iter.readInt();
}
System.out.println(total);
