Embed

Learn how to embed our in-house chat widget

---

You can embed the chat widget on your website. Simply copy the provided code and paste it anywhere within the tag of your HTML file.

Widget Setup

The following video shows how to inject the widget script into any webpage.

Using Specific Version

You can specify a specific version of flowise-embed to be used. For full list of versions: https://www.npmjs.com/package/flowise-embed

<script type="module">
  import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed@<some-version>/dist/web.js';
  Chatbot.init({
    chatflowid: 'abc',
    apiHost: 'http://localhost:3000',
  })
</script>

In v2.1.0, we have modified the way streaming works. If your Flowise version is lower than that, you might find your embedded chatbot not able to receive messages.

You can either update Flowise to v2.1.0 and above

Or, if for some reason you prefer not to update Flowise, you can specify the latest v1.x.x version of Flowise-Embed. Last maintained version is v1.3.14.

For instance:

https://cdn.jsdelivr.net/npm/flowise-embed@1.3.14/dist/web.js

Chatflow Config

You can pass chatflowConfig JSON object to override existing configuration. This is the same as Override Config in API.

<script type="module">
  import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
  Chatbot.init({
    chatflowid: 'abc',
    apiHost: 'http://localhost:3000',
    chatflowConfig: {
      "sessionId": "123",
      "returnSourceDocuments": true
    }
  })
</script>

Observer Config

This allows you to execute code in parent based upon signal observations within the chatbot.

<script type="module">
  import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
  Chatbot.init({
    chatflowid: 'abc',
    apiHost: 'http://localhost:3000',
    observersConfig: {
      // User input has changed
      observeUserInput: (userInput) => {
        console.log({ userInput });
      },
      // The bot message stack has changed
      observeMessages: (messages) => {
        console.log({ messages });
      },
      // The bot loading signal changed
      observeLoading: (loading) => {
        console.log({ loading });
      },
    },
  })
</script>

Theme

You can change the pop up button properties, as well as the chat window:

<script type="module">
  import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
  Chatbot.init({
    chatflowid: 'abc',
    apiHost: 'http://localhost:3000',
    theme: {
      button: {
        backgroundColor: '#3B81F6',
        right: 20,
        bottom: 20,
        size: 48, // small | medium | large | number

        iconColor: 'white',
        customIconSrc: 'https://raw.githubusercontent.com/walkxcode/dashboard-icons/main/svg/google-messages.svg',
        autoWindowOpen: {
          autoOpen: true, //parameter to control automatic window opening
          openDelay: 2, // Optional parameter for delay time in seconds
          autoOpenOnMobile: false, //parameter to control automatic window opening in mobile
        },
      },
      tooltip: {

        tooltipBackgroundColor: 'black',
        tooltipTextColor: 'white',
        tooltipFontSize: 16,

        backgroundColor: '#ffffff',
        backgroundImage: 'enter image path or link', // If set, this will overlap the background color of the chat window.
        height: 700,
        width: 400,
        fontSize: 16,
        starterPrompts: ['What is a bot?', 'Who are you?'], // It overrides the starter prompts set by the chat flow passed

        botMessage: {

          textColor: '#303235',
          showAvatar: true,

          showAvatar: true,
          avatarSrc: 'https://raw.githubusercontent.com/zahidkhawaja/langchain-chat-nextjs/main/public/usericon.png',
        },
        textInput: {
          placeholder: 'Type your question',
          backgroundColor: '#ffffff',
          textColor: '#303235',
          sendButtonColor: '#3B81F6',
          maxChars: 50,
          maxCharsWarningMessage: 'You exceeded the characters limit. Please input less than 50 characters.',
          autoFocus: true, // If not used, autofocus is disabled on mobile and enabled on desktop. true enables it on both, false disables it on both.
          sendMessageSound: true,
          // sendSoundLocation: "send_message.mp3", // If this is not used, the default sound effect will be played if sendSoundMessage is true.
          receiveMessageSound: true,
          // receiveSoundLocation: "receive_message.mp3", // If this is not used, the default sound effect will be played if receiveSoundMessage is true.
        },
        feedback: {
          color: '#303235',
        },
        footer: {
          textColor: '#303235',

Custom Modificaton

To modify the full source code of embedded chat widget, follow these steps:

1. Fork the Flowise Chat Embed repository

2. Then you can make any code changes

3. Run pnpm build to pick up the changes

4. Push changes to the forked repo

5. You can then use it as embedded chat like so:

Replace username to your Github username, and forked-repo to your forked repo.

<script type="module">
      import Chatbot from "https://cdn.jsdelivr.net/gh/username/forked-repo/dist/web.js"
      Chatbot.init({
          chatflowid: "chatflow-id",
          apiHost: "http://localhost:3000",
      })
</script>

<script type="module">
      import Chatbot from "https://cdn.jsdelivr.net/gh/HenryHengZJ/FlowiseChatEmbed-Test/dist/web.js"
      Chatbot.init({
          chatflowid: "chatflow-id",
          apiHost: "http://localhost:3000",
      })
</script>

An alternative to jsdelivr is unpkg. Here is an example:

https://unpkg.com/flowise-embed/dist/web.js

CORS

When using embedded chat widget, there's chance that you might face CORS issue like:

Access to fetch at 'https://<your-flowise.com>/api/v1/prediction/' from origin 'https://<your-flowise.com>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

To fix it, specify the following environment variables:

CORS_ORIGINS=*
IFRAME_ORIGINS=*

For example, if you are using npx flowise start

npx flowise start --CORS_ORIGINS=* --IFRAME_ORIGINS=*

If using Docker, place the env variables inside Flowise/docker/.env

If using local Git clone, place the env variables inside Flowise/packages/server/.env
