How To Install golang-github-valyala-fastjson-dev on Ubuntu 22.04
Introduction
In this tutorial we learn how to install golang-github-valyala-fastjson-dev
on Ubuntu 22.04.
What is golang-github-valyala-fastjson-dev
golang-github-valyala-fastjson-dev is:
No custom structs, no code generation, no reflection.
Features:
- Fast. As usual, up to 15x faster than the standard encoding/json.
- Parses arbitrary JSON without schema, reflection, struct magic and code generation contrary to easyjson.
- Provides a simple API.
- Outperforms jsonparser and gjson when accessing multiple unrelated fields, since fastjson parses the input JSON only once.
- Validates the parsed JSON unlike jsonparser and gjson.
- May quickly extract a part of the original JSON with Value.Get(…).MarshalTo and modify it with Del and Set functions.
- May parse array containing values with distinct types (aka non-homogenous types). For instance, fastjson easily parses the following JSON array [123, “foo”, [456], {“k”: “v”}, null].
- fastjson preserves the original order of object items when calling Object.Visit.
Known limitations:
- Requies extra care to work with - references to certain objects recursively returned by Parser must be released before the next call to Parse. Otherwise the program may work improperly. The same applies to objects returned by Arena.
- Cannot parse JSON from io.Reader.
Security:
- fastjson shouldn’t crash or panic when parsing input strings specially crafted by an attacker. It must return error on invalid input JSON.
- fastjson requires up to sizeof(Value) * len(inputJSON) bytes of memory for parsing inputJSON string. Limit the maximum size of the inputJSON before parsing it in order to limit the maximum memory usage.
