Getting Started

webpack.config.js

const path = require('path');

module.exports = {
  module: {
    rules: [
      {
        test: /\.proto$/,
        use: [
          {
            loader: 'webpack-grpc-web-loader',
            options: {
              protoPath: path.resolve(__dirname, './src/protos'),
            },
          },
        ],
      },
    ],
  },
};

If you have multiple proto paths, you can pass an array to the option protoPath:

{
  loader: 'webpack-grpc-web-loader',
  options: {
    protoPath: [
      path.resolve(__dirname, './src/my-protos-1'),
      path.resolve(__dirname, './src/my-protos-2'),
    ],
  },
}

In your src

import helloWorldProto from './hello-world.proto';

const client = new helloWorldProto.HelloWorldClient('http://localhost:11101/grpc');
const helloRequest = new helloWorldProto.HelloRequest();
client.helloWorld(helloRequest, {}, (err, res) => {
  // handle error and response here
});
