gRPC Getting Started

Demonstration of the use of gRPC and front-end.

Getting Started

Step 1. Install the grpc-web runtime library

$ cd /{your_directory}/grpc-getting-started
$ npm i grpc-web

Step 2. Install the code generator plugin protoc

$ PROTOC_ZIP=protoc-22.2-osx-x86_64.zip
$ curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v22.2/$PROTOC_ZIP
$ sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
$ sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
$ rm -f $PROTOC_ZIP

You can also use the following command to install (macOS)：

$ brew install protobuf

Check the version after the installation is complete

$ protoc --version

Step 3. Proceed to install the plugin protoc-gen-js

$ sudo npm i -g protoc-gen-js

Step 4. Compile and execute

Run the following command to compile the .proto file and generate a .js file we can recognize.

You can download protobuf-javascript to test

Or create your own files

proto/example.proto:

syntax = "proto3";

package hello;

// Greeting represents a message you can tell a user.
message Greeting {
  string message = 1;
}

The way to compile it:

$ mkdir hello
$ protoc  --proto_path=./proto --js_out=import_style=commonjs,binary:hello  proto/example.proto

or

$ npm run build

It will generate a file hello/example_pb.js
