grpc-tools
Advanced tools
The grpc-tools npm package provides tools for working with gRPC, including compiling Protocol Buffers (protobuf) files and generating gRPC service code. It is particularly useful for setting up gRPC services and clients in Node.js applications.
Compile Protobuf Files
This feature allows you to compile Protocol Buffers (protobuf) files into JavaScript code. The generated code can then be used to create gRPC clients and servers.
const grpc_tools_node_protoc = require('grpc-tools');
const execSync = require('child_process').execSync;
execSync(
'grpc_tools_node_protoc --js_out=import_style=commonjs,binary:. --grpc_out=. -I ./protos ./protos/helloworld.proto'
);
Generate gRPC Service Code
This feature generates the gRPC service code from protobuf definitions. The generated code includes both client and server stubs, which can be used to implement gRPC services.
const grpc_tools_node_protoc = require('grpc-tools');
const execSync = require('child_process').execSync;
execSync(
'grpc_tools_node_protoc --plugin=protoc-gen-grpc=`which grpc_tools_node_protoc_plugin` --grpc_out=. -I ./protos ./protos/helloworld.proto'
);
The grpc package is the core library for gRPC in Node.js. It provides the runtime for gRPC clients and servers, but does not include tools for compiling protobuf files. It is often used in conjunction with grpc-tools.
The @grpc/proto-loader package is used to load protobuf files in Node.js applications. It provides a more flexible and modern way to load protobuf files compared to grpc-tools, but does not include the ability to compile them.
The protobufjs package is a pure JavaScript implementation of Protocol Buffers. It provides tools for working with protobuf files, including compiling and loading them. It is more versatile than grpc-tools, but does not specifically target gRPC.
This package distributes the Protocol Buffers compiler protoc
along with the
plugin for generating client and service objects for use with the Node gRPC
libraries.
This library exports the grpc_tools_node_protoc
executable, which accepts all
of the same arguments as protoc
itself. For use with Node, you most likely
want to use CommonJS-style imports. An example of generating code this way can
be found in this guide.
The grpc_tools_node_protoc
automatically includes the Node gRPC plugin, so
it also accepts the --grpc_out=[option:]path
argument. The option can be
one of the following:
grpc_js
: Generates code with require('@grpc/grpc-js')
instead of
require('grpc')
generate_package_definition
: Generates code that does not require
any
gRPC library, and instead generates PackageDefinition
objects that can
be passed to the loadPackageDefinition
function provided by both the
grpc
and @grpc/grpc-js
libraries.FAQs
