Flexjson - Lightweight JSON parser

  •        226

Flexjson is a lightweight library for serializing Java objects into JSON. What's different about Flexjson is it's control over what gets serialized allowing both deep and shallow copies of objects.

Most JSON serializers mimic object serialization libraries and try to serialize the entire object graph from the object being turned into JSON. This causes problems when you want a connected object model in your server, but you can't send that object model to the client because the serialization library will try to send the entire object graph. This makes it very hard to create object oriented models and serialize pieces of that model to the client without sending everything. Other JSON libraries require you to create a lot of boiler plate code to translate your object representation into a JSON object.

json - JSON for Modern C++

  •    C++

Intuitive syntax. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the examples below and you'll know what I mean.Trivial integration. Our whole code consists of a single header file json.hpp. That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings.

easyjson - Fast JSON serializer for golang.

  •    Go

Package easyjson provides a fast and easy way to marshal/unmarshal Go structs to/from JSON without the use of reflection. In performance tests, easyjson outperforms the standard encoding/json package by a factor of 4-5x, and other JSON encoding packages by a factor of 2-3x. easyjson aims to keep generated Go code simple enough so that it can be easily optimized or fixed. Another goal is to provide users with the ability to customize the generated code by providing options not available with the standard encoding/json package, such as generating "snake_case" names or enabling omitempty behavior by default.

Jsmn - World fastest JSON parser/tokenizer

  •    C

jsmn (pronounced like 'jasmine') is a minimalistic JSON parser in C. It can be easily integrated into resource-limited or embedded projects. Most JSON parsers offer you a bunch of functions to load JSON data, parse it and extract any value by its name. jsmn proves that checking the correctness of every JSON packet or allocating temporary objects to store parsed JSON fields often is an overkill.

jsonstreamingparser - A JSON streaming parser implementation in PHP.

  •    PHP

This is a simple, streaming parser for processing large JSON documents. Use it for parsing very large JSON documents to avoid loading the entire thing into memory, which is how just about every other JSON parser for PHP works. For more details, I've written up a longer explanation of the JSON streaming parser that talks about pros and cons vs. the standard PHP JSON parser.
