# gRPC Getting Started

Demonstration of the use of gRPC and front-end.


![quick overview](preview.gif)


## (Ⅰ) Original tutorial (simple)

- [(original version)English Documentation](README_TUTORIAL.md)
- [(最初版)中文版说明文档](README_TUTORIAL_CN.md)


## (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`.

```sh
$ npm run proxy
```

### Step 2: User Interaction Test


 - the NodeJS gRPC Service (port `9090`)
 - the webpack server (port `10005`)


run following command to test:

```sh
$ 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.

```sh
$ 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`

```sh
$ 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`

```sh
$ npm run build:api-prod
```
or

```sh
$ npm run build:api-dev
```

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

```js
$ npm run proxy
$ npm run test:api
```

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