A high-performance JSON parser and toolkit for Go, optimized for large and variable datasets.
OjG (Optimized JSON for Go) is a high-performance JSON parser and toolkit for the Go programming language. It is designed to efficiently process large datasets, especially those with variable or non-fixed structures, by providing faster parsing, validation, and writing compared to standard Go JSON libraries. The toolkit includes a full JSONPath implementation, generic JSON types, and a command-line utility for JSON manipulation.
Go developers working with JSON data, particularly those handling large-scale or unstructured datasets, needing performance optimizations, or requiring advanced JSON querying and manipulation capabilities.
Developers choose OjG for its significant performance gains over standard Go JSON libraries, its comprehensive feature set including JSONPath and SEN, and its flexibility in handling diverse JSON structures without sacrificing speed.
Optimized JSON for Go
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarks show OjG's parser is up to 3.13x faster than json.Unmarshal with reuse, making it ideal for high-throughput data processing, as highlighted in the README's performance comparisons.
Implements comprehensive JSONPath expressions for querying JSON data, including support for structs, enabling complex data extraction like filtering with 'a[?(@.x > 1)].y'.
Includes a validator 7x faster and a writer 4x faster than standard libraries, optimizing end-to-end JSON handling for large datasets, per the README benchmarks.
Offers Simple Encoding Notation, a relaxed JSON syntax that omits commas and quotes, simplifying manual JSON writing and parsing for configurations or informal data.
Uses its own generic types instead of Go's built-in generics, which may confuse developers accustomed to standard interfaces and require adaptation for type-safe operations.
As an external library, it has a smaller ecosystem and community support compared to Go's standard encoding/json, potentially leading to dependency management issues or fewer integrations.
Advanced features like JSONPath and assembly plans add overhead for straightforward JSON tasks, where the standard library might be simpler and sufficient.
