Gjson
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, floats, booleans, maps, or slices. The toolset also covers JSON syntax validation, array searching with comparison operators, and the ability to reshape or transform JSON data into new structures.
Features
- JSON Path Navigation - Navigates JSON hierarchies by matching dot-notation path segments against keys during the scanning process.
- Value Extraction - Extracts data directly from the source bytes without requiring predefined Go structs or interface maps.
- Native Type Converters - Provides on-demand conversion of extracted JSON values into native Go strings, floats, booleans, maps, or slices.
- JSON - Finds and filters data within JSON arrays and objects using dot notation, wildcards, and comparison operators.
- JSON Data Parsers - Retrieves specific values from JSON documents in Go using paths without needing to define complex structs.
- JSON Parsers - Provides a library for extracting values from JSON documents using dot-notation paths without requiring predefined Go structs.
- Path Extractors - Retrieves specific data from JSON objects and arrays using wildcards and index-based queries.
- Zero-Copy Deserialization - Returns views into the original byte slice rather than allocating new strings for every extracted value.
- Zero-Copy Parsers - Scans raw byte slices to locate values without decoding the entire document into memory structures.
- Map Converters - Allows for the transformation of JSON documents into native Go map structures.
- Structure Iterators - Provides a mechanism to traverse JSON arrays and objects via user-defined callback functions.
- JSON - Parses and iterates through multi-line JSON documents to handle large datasets or log files efficiently.
- Data Type Casting - Converts raw JSON bytes into native Go types only when explicitly requested by the user.
- JSON Processors - Reshapes or formats JSON data by applying modifiers and combining paths into new structures.
- JSON - Treats multi-line documents as arrays to iterate and query individual JSON entries.
- Type Mapping Converters - Transforms JSON values into native Go strings, floats, booleans, maps, or slices.
- Procesare JSON - Fast JSON parsing with a simple API.
