This benchmark compares serialization and deserialization throughput in JavaScript for Apache Fory, Protocol Buffers, and JSON.

It mirrors the benchmark layout used by benchmarks/cpp and uses the shared schema in benchmarks/proto/bench.proto.

• Struct
• Sample
• MediaContent
• StructList
• SampleList
• MediaContentList

For Fory, all struct schemas use explicit type IDs and field IDs so compatible-mode type metadata stays compact. The numeric type IDs match the C++ benchmark registration order.

cd benchmarks/javascript
./run.sh

./run.sh --help

Options:
  --data <struct|sample|mediacontent|structlist|samplelist|mediacontentlist>
                               Filter benchmark by data type
  --serializer <fory|protobuf|json>
                               Filter benchmark by serializer
  --duration <seconds>         Minimum time to run each benchmark

Examples:

./run.sh --data struct
./run.sh --serializer fory
./run.sh --data sample --serializer protobuf --duration 10

Running the pipeline writes:

• raw benchmark JSON to benchmarks/javascript/benchmark_results.json
• plots to docs/benchmarks/javascript/*.png
• Markdown report to docs/benchmarks/javascript/README.md

• The benchmark builds the JavaScript package from javascript/ before running.
• Protobuf uses protobufjs with the shared bench.proto schema.
• JSON results use UTF-8 byte length for serialized size.
