# DEMO

https://riversun.github.io/chatux/

<img src="https://riversun.github.io/chatux/chatux_qr.png">

**How to play demo.**

This demo is simple echo chat. But a few command available.If you write "show buttons", you can see action buttons in
chat. Or you write "show image", you can see image in chat.

Example project is available on this repo.

## install and minimal code

### using npm

**install**

```
npm install chatux --save
```

**code**

```js
import {ChatUx} from 'chatux';

const chatux = new ChatUx();

chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',//chat server
    method: 'GET',//HTTP METHOD when requesting chat server
    dataType: 'json',//json or jsonp is available
    escapeUserInput: true,//true:Escaping HTML tags in user input text when submitting to the server. default is false.
  }
});

chatux.start();
```

### using with script tag

```
<script src="https://cdn.jsdelivr.net/npm/chatux/dist/chatux.min.js"></script>
```

**code**

```js
const chatux = new ChatUx();

chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',//chat server
    method: 'GET',//HTTP METHOD when requesting chat server
    dataType: 'json',//json or jsonp is available
    escapeUserInput: true,// true:Escaping HTML tags in user input text when submitting to the server. default is false.
  }
});

chatux.start();

```

# How it works

The system of **chatux** is very simple.

Let's look at the execution sequence of **chatux**.

Suppose you have a chat server for **chatux** at http://localhost:8080/chat
Specify server endpoint like this.

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
    escapeUserInput: true,// true:Escaping HTML tags in user input text when submitting to the server. default is false.
  }
});

```

The following is the sequence.

![image](https://user-images.githubusercontent.com/11747460/54331314-d3735f80-465c-11e9-9a22-5a975809f770.png)

-
    1. **chatux** sends user input text to chat server.  
       GET http://localhost:8080/chat?text=hello

-
    2. The server processes user input text and returns a response as JSON.

```json
{
  "output": [
    {
      "type": "text",
      "value": "You say 'hello'"
    }
  ]
}
```

-
    3. According to the response, **chatux** renders the result on the chat screen.  
       ![image](https://user-images.githubusercontent.com/11747460/54341678-c4e97000-467d-11e9-96e5-090d4ac8ba9c.png)

So, if you create chat server that can do this kind of interaction, you can easily create chatbots etc.

Next, let's see how to render.

# Chat server

Let's create a simple chat server.

* initialize npm project and install express

```shell
npm init
npm install express
```

* Write a simple server that returns json.

```js
const express = require('express');
const app = express();
const port = 8080;

// enabling CORS
app.use(function (req, res, next) {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Headers', '*');
  next();
});
app.get('/chat', function (req, res) {
  const userInputText = req.query.text;

const response = {
    output: []
  };

const msg = response.output;
  msg.push({
    type: 'text',
    value: `You say ${userInputText}`
  });
  res.json(response);
});

app.listen(port, () => {
  console.log('chat server started on port:' + port);
});

```

* start server

```shell
npm start
```

* Access directory

http://localhost:8081/chat?text=hello

You will get JSON for chatux as follows.

```json
{
  "output": [
    {
      "type": "text",
      "value": "You say hello"
    }
  ]
}
```

* Access from **ChatUX** on browser

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
    escapeUserInput: true,
  }
});
chatux.start(true);//true:automatically open chat

```

# Custom query parameters

There are two approaches to specifying query parameters.

1.Custom query parameters can be set at initialization.

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
    params: {
      'param1': 'value1',
      'param2': 'value2'
    }
  }
});

```

chat ux will send parameters like 'https://example.com/api?param1=value1&param2=value2'

2.Custom parameters can be set at each request.

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
  },
  methods: {
    onPrepareRequest: (httpClient) => {
      //intercept http request before sending and set query parameters
      httpClient.params.param1 = 'value1';
      httpClient.params.param2 = 'value2';
    },
    onFinishRequest: (httpClient) => {
      //delete params after sending
      delete httpClient.params.param1;
      delete httpClient.params.param2;
    }
  }
});

```

If nothing is set, only the query parameter named 'text' will be set when you tap send button.

# Custom Http Headers

There are two approaches to set http headers.

1.Custom headeres can be set at initialization.

You can specify http-headers like as follows.

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
    escapeUserInput: true,
    headers: {
      'Authorization': 'Bearer ABCD123ABCD123ABCD123',
      'X-Additional-Headers': 'something_value'
    }
  }
});

```

2.Custom headers can be set at each request.

```js
chatux.init({
  api: {
    endpoint: 'http://localhost:8080/chat',
    method: 'GET',
    dataType: 'json',
    escapeUserInput: true,
  },
  methods: {
    onPrepareRequest: (httpClient) => {
      httpClient.headers = {};
      httpClient.headers['Authorization'] = 'Bearer ABCD123ABCD123ABCD123';
      httpClient.headers['X-Additional-Headers'] = 'something_value';
    }
  }
});

```

**Note**

- Http headers cannot be sent when using jsonp.
- Don't forget 'Access-Control-Allow-Headers' when accessing with cors :)

# How to render a chat UI

Since chatux can render various variations of chat UI, I introduce them below. I want to show raw JSON and code example
for chat server respectively.

### Show text

**SERVER CODE**

```js
app.get('/chat', function (req, res) {
  const response = {output: []};

  });
  res.json(response);
});
```

**JSON**

```json
{
  "output": [
