simdjson is a high-performance, header-only C++ library designed for parsing, querying, and serializing JSON data with minimal memory overhead. It functions as a hardware-aware data processing engine that leverages vector instructions to achieve gigabyte-per-second parsing speeds. By detecting host processor capabilities at runtime, the library automatically selects the most efficient instruction sets to accelerate structural analysis and validation. The library distinguishes itself through a focus on extreme efficiency and resource management. It utilizes memory mapping and padded buffer ali

gjson is a Go JSON parser designed for schema-less reading and value extraction. It allows for the retrieval of specific data from JSON documents using dot-notation paths without requiring the definition of predefined Go structs. The library provides tools for path-based querying, including the use of wildcards and index-based queries to locate data within objects and arrays. It also functions as a JSON lines processor, treating multi-line documents as arrays to iterate and query individual entries. Additional capabilities include converting JSON values into native Go types such as strings,

RapidJSON is a high-performance C++ library used for parsing and generating JSON data. It provides both document object model and stream-based interfaces to transform JSON strings into structured data and vice versa. The library includes a JSON schema validator to verify that documents conform to predefined rules and a Unicode transcoder for converting strings between UTF-8, UTF-16, and UTF-32 encodings. It also supports relaxed parsing for non-standard JSON containing comments or trailing commas. Additional capabilities cover JSON pointer navigation for locating specific values and string s

oboe.js 是一个流式 JSON 解析器和 HTTP 流客户端，专为增量数据处理而设计。它允许应用程序在网络请求或可读流到达时，在整个下载完成之前对单个 JSON 对象进行处理。 该库作为 JSON 流转换器，支持在传输过程中对节点进行修改、过滤和映射。它具有基于路径的节点选择功能，可在匹配特定模式时触发回调，并能在找到所需数据后提前终止网络连接以节省带宽。 为了处理超出系统可用内存的数据集，该库利用基于流的内存管理来丢弃已处理的节点。它还支持通过长连接将历史记录与实时更新合并，并提供在连接中断时恢复部分数据的能力。
