## What is a webchat?

The SAP Conversational AI webchat let you **deploy a bot straight to a website**. It will be embed and available through a chat box on your pages.
The webchat is one of the many channels available on [SAP Conversational AI](https://cai.tools.sap), and end-to-end bot building platform.
This webchat is built using the [React](https://github.com/facebook/react) library, along with [Redux](https://github.com/reactjs/redux) for state managment.

## Compatibility

This webchat is supported by all mobile and desktop browsers in their latest versions.
Internet Explorer support starts at version 9.0.

## Usage

Three different installations on the webchat module are possible.
- The default is the simplest and fatest route, and offers some customization options.
- The self-hosted webchat offers even more customization option, but you'll have to deal with the hosting and maintenance of the module.
- Use it as a React component

### Default webchat

To use the webchat, you need an account on [SAP Conversational AI](https://cai.tools.sap) and a bot.
Then, go to the **CONNECT** tab and click on **Webchat**. It will open a window that lets you adjust your webchat settings, including:
* color scheme,
* header customization,
* bot and user pictures,
* webchat logo and call to action,
* conversation duration

Once you're satisfied with the settings, click on the **SAVE** button. A script tag appears, and you just have to copy paste it in your web page to embed the webchat. The script must be placed in the `<body>` tag.

### Self-hosted webchat

If you want to customize your webchat even more, you can opt for a self-hosted installatiton. Just fork this project to get started!

#### Installation

Clone the repository you forked, and install the dependencies.

```
$> git clone YOUR_REPO_URL
$> cd webchat
$> npm install
```

#### Run in development mode

```
$> npm run start
```

#### Eslint + prettier

```
$> npm run prettier
```

#### Build for production

```
$> npm run build
```

#### Use your webchat

Once you're done, build it and host it.
To use it instead of the default one provided by SAP Conversational AI, you need to set up the Webchat channel in the **CONNECT** tab of your bot.
You'll be using the same script as the default installation, but you have **to replace the src field by your own URL**.

```
<script
  src="YOUR_WEBCHAT_URL"
  ...
></script>
```

### React component
You can import the webchat as a React component like the following example:
``` js
import CaiWebchat from 'webchat';

export default class ReactWebchat extends Component {
  render() {
    return (
      <CaiWebchat
        onRef={ref => {
          this.webchat = ref;
        }}
        channelId={YOUR_CHANNEL_ID}
        token={YOUR_TOKEN}
        preferences={{
          accentColor: '#E05A47',
          complementaryColor: '#FFFFFF',
          botMessageColor: '#707070',
          botMessageBackgroundColor: '#F6F6F6',
          backgroundColor: '#FFFFFF',
          headerLogo: 'https://cdn.cai.tools.sap/webchat/webchat-logo.svg',
          headerTitle: 'My awesome chatbot',
          botPicture: 'https://cdn.cai.tools.sap/webchat/bot.png',
          userPicture: 'https://cdn.cai.tools.sap/webchat/user.png',
          onboardingMessage: 'Come speak to me!',
          expanderLogo: 'https://cdn.cai.tools.sap/webchat/webchat-logo.svg',
          expanderTitle: 'Click on me!',
          conversationTimeToLive: 24,
          openingType: 'never',
          welcomeMessage: 'Hello world !',
        }}
        getLastMessage={message => {
          console.log(message)
        }}
      />
    );
  }
}
```

|clearMessages()|Clear all messages in the webchat|

### Bot Memory management
One thing you might want to do is to send custom data from your website to the bot, like the name of the logged in user, his ID, the page he is currently on (to send product suggestions for example). To do that, you can define a `window.webchatMethods.getMemory` function, the webchat will call it before sending user messages, and send your arbitrary payload along with the message to the bot.

If you use SAP Conversational AI's bot-builder (you should :)), your payload will be put in the memory of the conversation, meaning that you will be able to access this data in your bot-builder. Let's say you send this as payload : `{ "userName": "Dominik", "userId": 123456 }`, you will then be able to send this as a greeting message : `Hello {{ memory.userName }} ! How do you do ?`.

`window.webchatMethods.getMemory` must return a JSON object or a Promise resolving a JSON object :
  - `{ "memory": { ... }, "merge": <boolean> }`
where `{ ... }` is your arbitrary payload. `merge` is an instruction for the bot-builder. If set to true, the payload will be merged with the existing memory, overriding common keys but keeping the ones absent from the payload. If set to false, the memory will be replaced entirely by your payload.

If your `getMemory` function takes more than 10 seconds, the message will be sent anyway, without waiting for your function to finish.

#### Examples :
```html
<html>
  <head>
    <script>
      window.webchatMethods = {
        // called at each user message
        getMemory: (conversationId) => {
          const memory = { userName: 'Dominik Bousquet', userId: 123456 }
          return { memory, merge: true }
        }
      }
    </script>
  </head>
  <body>
    <script src="https://cdn.cai.tools.sap/webchat/webchat.js"
      channelId="<channelId>"
      token="<token>"
      id="cai-webchat"
    ></script>
  </body>
</html>
```

```javascript
window.webchatMethods = {
  getMemory: (conversationId) => {
    const getCookie = (name) => {
      const value = document.cookie.match('(^|;) ?' + name + '=([^;]*)(;|$)')
      return value ? value[2] : null
    }
    const userName = getCookie('userName')
    const memory = { userName, currentUrl: window.location.href }
    return { memory, merge: true }
  }
}
```

```javascript
window.webchatData = {}
window.webchatMethods = {
  getMemory: (conversationId) => {
    if (window.webchatData.savedUserData) {
      return { memory: window.webchatData.savedUserData, merge: true }
    }
    return new Promise((resolve, reject) => {
      axios.get('/current_user')
        .then((response) => {
          const memory = { userName: response.data.name, userId: response.data.id }
          window.webchatData.savedUserData = memory
          resolve({ memory, merge: true })
        })
        .catch(reject)
    })
  }
}
```

```javascript
window.webchatData = {}
window.webchatMethods = {
  getMemory: (conversationId) => {
    if (!window.webchatData.oriUrl) {
      window.webchatData.oriUrl = window.location.href
    }
    // merge: false - reset the conversation if the user
    // switched to another page since the first message
    if (window.webchatData.oriUrl !== window.location.href) {
      return { memory: {}, merge: false }
    }
    return { memory: { userName: 'Dominik' }, merge: true }
  }
}
```
