JavaScript¶

You can integrate a simple HTML page with Alan using JavaScript without any frameworks.

Integrating with Alan AI¶

You can add the Alan AI agentic interface to your page in two ways:

With the npm package
In the browser library mode

NPM package

In the Terminal, run the command:

Terminal¶

npm install @alan-ai/alan-sdk-web --save

Add a <div> for appending the Alan AI agentic interface:
Client app¶
```
<div class="alan-btn"></div>
```

Import the alanBtn function from the @alan-ai/alan-sdk-web package and add the Alan AI agentic interface to the page:

Client app¶

import alanBtn from "@alan-ai/alan-sdk-web";

var alanBtnInstance = alanBtn({
  key: "YOUR_KEY_FROM_ALAN_STUDIO_HERE",
  host: "v1.alan.app",
  onCommand: function (commandData) {
    if (commandData.command === "go:back") {
      // Call the client code that will react to the received command
    }
  },
  rootEl: document.getElementById("alan-btn"),
});

(For Alan AI Web Chat) Add a link to the font to the <head> section of the HTML page:

Client app¶

<link href="https://fonts.googleapis.com/css2?family=Poppins:ital,wght@0,100;0,200;0,300;0,400;0,500;0,600;0,700;0,800;0,900;1,100;1,200;1,300;1,400;1,500;1,600;1,700;1,800;1,900&display=swap" rel="stylesheet">

Browser library mode

Add the <script> tag to the page:

Client app¶

<script type="text/javascript" src="https://studio.alan.app/web/lib/alan_lib.min.js"></script>

Add a <div> for appending the Alan AI agentic interface:
Client app¶
```
<div class="alan-btn"></div>
```

Add the Alan AI agentic interface in the <script> tag like this:

Client app¶

<script>
  var alanBtnInstance = alanBtn({
    key: "YOUR_KEY_FROM_ALAN_STUDIO_HERE",
    host: "v1.alan.app",
    onCommand: function (commandData) {
      if (commandData.command === "go:back") {
        // Call the client code that will react to the received command
      }
    },
    rootEl: document.getElementById("alan-btn"),
  });
</script>

(For Alan AI Web Chat) Add a link to the font to the <head> section of the HTML page:

Client app¶

<link href="https://fonts.googleapis.com/css2?family=Poppins:ital,wght@0,100;0,200;0,300;0,400;0,500;0,600;0,700;0,800;0,900;1,100;1,200;1,300;1,400;1,500;1,600;1,700;1,800;1,900&display=swap" rel="stylesheet">

Note

Mind the following:

Regularly update the @alan-ai/alan-sdk-web package your project depends on. To check if a newer version is available, run npm outdated. To update the alan package, run npm update @alan-ai/alan-sdk-web. For more details, see npm documentation.
If you add the Alan AI agentic interface to a multi-page app or website, the Alan AI agentic interface will be reloaded on every redirect or page refresh. To store and access the data required for the dialog session, use the localStorage and sessionStorage objects. Alternatively, you can design your project as a single-page app.

Specifying the Alan AI agentic interface parameters¶

You can specify the following parameters for the Alan AI agentic interface added to your app:

Name	Type	Description
`key`	string	The Alan AI SDK key for a project in Alan AI Studio.
`host`	string	The Alan AI Studio host to which the AI assistant button must connect, for example: `'v1.alan.app'`.
`theme`	string	The default theme to be used for the Alan AI agentic interface and Text Chat, for example: `'light'` or `'dark'`.
`authData`	JSON object	The authentication or configuration data to be sent to the dialog script. For details, see authData.
`rootEl`	HTMLElement	The element where Alan AI agentic interface will be added. If no `rootEl` is provided, the Alan AI agentic interface is added to the `body`.
`mode`	string	Specifies how the Agentic Interface should be rendered. Use `'inlined'` to render the Agentic Interface inline in the div. If not specified, the Agentic Interface will be rendered as popup.

textChat Properties

Name	Type	Description
`closeDelay`	number	Specifies the delay (in milliseconds) for the close animation in inline mode.
`showBtnIfChatOpen`	boolean	Determines whether the Agentic Interface should be shown in inline mode.
`openByDefault`	boolean	Indicates whether the Agentic Interface should be open or closed by default when rendered in inline mode.
`onOpen`	function	A callback function that is triggered when the Agentic Interface is opened.
`onClose`	function	A callback function that is triggered when the Agentic Interface is closed.
`onMinimize`	function	A callback function that is triggered when the Agentic Interface is minimized.
