LanguageProject Introduction
Summary
easyjson is a Go library that generates Go code for marshaling/unmarshaling Go structs to/from JSON, focusing on speed and efficiency. It aims to replace or augment the standard library's JSON handling in performance-sensitive scenarios.
Problem Solved
The standard `encoding/json` package in Go can be a performance bottleneck in high-throughput applications. easyjson solves this by providing a code-generated, highly optimized alternative for JSON serialization/deserialization.
Core Features
Code Generation
Automatically generates Go code for efficient marshaling and unmarshaling of Go structs to and from JSON.
High Performance
Achieves significantly higher performance compared to the standard `encoding/json` package through optimized code.
Seamless Integration
Supports integration with existing Go types and the standard library's `json.Marshaler`/`json.Unmarshaler` interfaces.
Tech Stack
Golang
Use Cases
easyjson is particularly useful in scenarios where JSON encoding and decoding speed are critical factors:
High-Throughput Web Services
Details
Building web services or APIs that handle a high volume of requests with complex JSON payloads where serialization overhead needs to be minimized.
User Value
Reduced response times and increased service capacity by accelerating JSON processing.
Large-Scale Data Processing
Details
Processing large JSON files or streams as part of data ingestion, transformation, or analysis pipelines.
User Value
Faster data processing throughput and reduced compute costs.
