easy is a fast JSON serializer for Go that generates marshaler/unmarshaler code for structs via a CLI code generator, avoiding reflection. It claims 4-5x faster marshaling/unmarshaling than the standard encoding/ package.
Use cases
- serialize Go structs to JSON fast
- unmarshal JSON without reflection overhead
- generate JSON marshaler code for my structs
- speed up JSON encoding in a high-throughput Go API
- customize JSON field naming like snake_case
- replace encoding/ for performance-critical paths
When to choose
- JSON serialization is a profiling bottleneck in a Go service
- you want generated, inspectable, optimizable marshaler code
- you need options like default omitempty or snake_case keys
When to avoid
- you need dynamic serialization of arbitrary data without code generation
- your workload is not JSON-bound and standard encoding/ is fast enough
- you cannot run a code generation step in your build
