To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package. + ## Migrating from [`grpc`](https://www.npmjs.com/package/grpc) + + `@grpc/grpc-js` is almost a drop-in replacement for `grpc`, but you may need to make a few code changes to use it: + + - If you are currently loading `.proto` files using `grpc.load`, that function is not available in this library. You should instead load your `.proto` files using `@grpc/proto-loader` and load the resulting package definition objects into `@grpc/grpc-js` using `grpc.loadPackageDefinition`. + - If you are currently loading packages generated by `grpc-tools`, you should instead generate your files using the `--generate_package_definitions` option in `grpc-tools`, then load the object exported by the generated file into `@grpc/grpc-js` using `grpc.loadPackageDefinition`. + - If you have a server and you are using `Server#bind` to bind ports, you will need to use `Server#bindAsync` instead. + ## Some Notes on API Guarantees The public API of this library follows semantic versioning, with some caveats:
