A repository which runs the protocol buffers conformance test suite against various implementations.

The current implementations being tested are:

• Protobuf-ES: https://github.com/bufbuild/protobuf-es
• protobuf-ts: https://github.com/timostamm/protobuf-ts
• google-protobuf: https://github.com/protocolbuffers/protobuf-javascript
• protobuf.js: https://github.com/protobufjs/protobuf.js/
• protoc-gen-ts: https://github.com/thesayyn/protoc-gen-ts
• ts-proto: https://github.com/stephenh/ts-proto

Implementation	JavaScript	TypeScript	Standard Plugin	Required tests	Recommended tests
Protobuf-ES	✔️	✔️	✔️	(0 failures)	(1 failures)
protobuf-ts	✔️	✔️	✔️	(6 failures)	(5 failures)
google-protobuf	✔️	❌	✔️	(387 failures)	(216 failures)
protobuf.js	✔️	✔️	❌	(928 failures)	(471 failures)
protoc-gen-ts	❌	✔️	✔️	(1085 failures)	(369 failures)
ts-proto	❌	✔️	✔️	(850 failures)	(528 failures)

Note: None of the libraries tested implement the text format so the results for those test runs are not shown.

First, verify that Bazel is installed. Using Bazelisk is recommended.

To run the conformance tests, run make from the repo root.

If you are on Apple M1 and see the error symbol not found in flat namespace (_CFRelease) when building protoc, you may need to install XCode from the Apple App Store.
