(Ⅱ) How to use this repository

Step 1: Run the Envoy proxy.

The envoy.yaml file configures Envoy to listen to browser requests at port 12345, and forward them to port 9090.

$ npm run proxy

Step 2: User Interaction Test

• the NodeJS gRPC Service (port 9090)
• the webpack server (port 10005)

run following command to test:

$ npm run start

When these are all ready, you can open a browser tab and navigate to http://localhost:10005

Step 3: (optional) Build proto files and client files

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

$ npm run build:protos

b) Create client file

It will generate a js file dist/client-main.js and a html file dist/index.html

$ npm run build:client

(Ⅲ) Create a API file

This file is to call with <script>, which is used as the interface of gRPC API.

Execute the build command below, it will generate a js file dist-api/api-main.js and a html file dist-api/index.html

$ npm run build:api-prod

or

$ npm run build:api-dev

Next, Use api-main.js to call the interface and run following command:

$ npm run proxy
$ npm run test:api

Visit http://localhost:4002 to test, it will output in the console: "Hello: string 1 string 2"
