npm install automatically downloads the correct version of the wasm bundle and diff-server.

rm -rf bin/repc
ln -s /path/to/repc/pkg/Release bin/repc
npm run build

Note that if you run npm install subsequently, you'll nuke that link and have to create it again.

The build script copies to a new directory, so you need to re-run npm run build each time you modify repc.

We continuously track performance across a variety of benchmarks. Results here:
