    Table of Contents


    # Using npm
    npm install --save vue-advanced-chat
    # Using yarn
    yarn add --save vue-advanced-chat


    You can import it as a custom component:

      <chat-window :currentUserId="currentUserId" :rooms="rooms" :messages="messages" />
      import ChatWindow from 'vue-advanced-chat'
      import 'vue-advanced-chat/dist/vue-advanced-chat.css'
      export default {
        components: {
        data() {
          return {
            rooms: [],
            messages: [],
            currentUserId: 1234

    Important notes

    vue-advanced-chat component is performance oriented, hence you have to follow specific rules to make it work properly.

    • Use array assignement instead of push method
    // DO THIS
    const rooms = []
    for (let i = 0; i < res.length; i++) {
    this.rooms = rooms
    // DON'T DO THIS
    for (let i = 0; i < res.length; i++) {
    // DO THIS
    this.rooms[i].typingUsers = [...this.rooms[i].typingUsers, typingUserId]
    // DON'T DO THIS
    • To add or replace an item inside an array, use $set method or spread operator
    // DO THIS
    this.$set(this.rooms, roomIndex, room)
    // OR DO THIS
    this.rooms[roomIndex] = room
    this.rooms = [...this.rooms]
    // DON'T DO THIS
    this.rooms[roomIndex] = room
    • Follow the UI loading pattern by updating messagesLoaded prop every time a new room is fetched
    fetchMessages({ room, options }) {
      this.messagesLoaded = false
      this.messages = []
      // use timeout to imitate async server fetched data
      setTimeout(() => {
        this.messagesLoaded = true
      }, 0)

    (1) currentUserId is required to display UI and trigger actions according to the user using the chat (ex: messages position on the right, etc.)

    (2) loadingRooms can be used to show/hide a spinner icon while rooms are loading

    (3) roomId can be used to load a specific room at any time

    (4) loadFirstRoom can be used to remove the default behaviour of opening the first room at initialization

    (5) roomMessage can be used to add a default textarea value

    (6) messagesLoaded must be manually set to true when all messages of a conversation have been loaded. Meaning the user cannot scroll on top anymore

    (7) menuActions can be used to display your own buttons when clicking the vertical dots icon inside a room.
    You can then use the menuActionHandler event to call your own action after clicking a button. Ex:

        name: 'inviteUser',
        title: 'Invite User'
        name: 'removeUser',
        title: 'Remove User'
        name: 'deleteRoom',
        title: 'Delete Room'

    (8) messageActions can be used to display your own buttons when clicking the dropdown icon inside a message.
    You can then use the messageActionHandler event to call your own action after clicking a button. Ex:

        name: 'addMessageToFavorite',
        title: 'Add To Favorite'
        name: 'shareMessage',
        title: 'Share Message'

    You can use built-in messageActions names to trigger specific UI modifications when clicked.
    Currently, replyMessage, editMessage and deleteMessage action names are available.
    If messageActions is not set, it will use the default values below.
    If you don't want to display this messageActions menu, you can pass it an empty array.

        name: 'replyMessage',
        title: 'Reply'
        name: 'editMessage',
        title: 'Edit Message',
        onlyMe: true
        name: 'deleteMessage',
        title: 'Delete Message',
        onlyMe: true

    (9) showNewMessagesDivider can be used to show/hide the blue line divider between seen and unseen messages.

    (10) textMessages can be used to replace default i18n texts. Ex:

      ROOMS_EMPTY: 'Aucune conversation',
      ROOM_EMPTY: 'Aucune conversation sélectionnée',
      NEW_MESSAGES: 'Nouveaux messages',
      MESSAGE_DELETED: 'Ce message a été supprimé',
      MESSAGES_EMPTY: 'Aucun message',
      CONVERSATION_STARTED: 'La conversation a commencée le :',
      TYPE_MESSAGE: 'Tapez votre message',
      SEARCH: 'Rechercher',
      IS_ONLINE: 'est en ligne',
      LAST_SEEN: 'dernière connexion ',
      IS_TYPING: 'est en train de taper...'

    (11) textFormatting can be used to add text formatting. Currently, bold, italic, strikethrough, underline, inline code and multiline code formatting are available and can be used in conjonction. You can disable text formatting by passing the prop as :textFormatting="false".

    Style Syntax Example Output
    Bold * * *This is bold text* This is bold text
    Italic _ _ _This text is italicized_ This text is italicized
    Strikethrough ~ ~ ~This was mistaken text~ This was mistaken text
    Underline ° ° °This text is underlined° This text is underlined
    Nested formatting * * and _ _ *This text is _extremely_ important* This text is extremely important

    Inline Code

    Example: `This is inline code`

    Output: This is inline code

    Multiline Code

    Example: ```This is multiline code```


    This is
    multiline code

    (12) responsiveBreakpoint can be used to collapse the rooms list on the left when then viewport size goes below the specified width.

    (13) singleRoom can be used if you never want to show the rooms list on the left. You still need to pass the rooms prop as an array with a single element.

    (14) theme can be used to change the chat theme. Currently, only light and dark are available.

    (15) styles can be used to customize your own theme. Ex:

      general: {
        color: '#0a0a0a',
        backgroundInput: '#fff',
        colorPlaceholder: '#9ca6af',

    Props data structure

    Your props must follow a specific structure to display rooms and messages correctly:

    Rooms prop

        roomId: 1,
        roomName: 'Room 1',
        avatar: 'assets/imgs/people.png',
        unreadCount: 4,
        lastMessage: {
          content: 'Last message received',
          sender_id: 1234,
          username: 'John Doe',
          timestamp: '10:20',
          date: 123242424,
          saved: true,
          distributed: false,
          seen: false,
          new: true
        users: [
            _id: 1234,
            username: 'John Doe',
            avatar: 'assets/imgs/doe.png',
            status: {
              state: 'online',
              last_changed: 'today, 14:30'
            _id: 4321,
            username: 'John Snow',
            avatar: 'assets/imgs/snow.png',
            status: {
              state: 'offline',
              last_changed: '14 July, 20:00'
        typingUsers: [ 4321 ]
    • If you set a date to lastMessage property, your rooms will be ordered using this date value. date can be any sortable value, like a string, datetime, timestamp, etc.

    • For each room user, you can add the status property, which can hold the state and last_changed properties:

      • state can be 'online' or 'offline'
      • last_changed is the date when state was last modified.
    • typingUsers is an array of all the users who are currently writing a message

    Messages prop

    Message objects are rendered differently depending on their type. Currently, only text, emoji and file types are supported.

    Each message object has a sender_id field which holds the id of the corresponding agent. If sender_id matches the currentUserId prop, specific UI and actions will be implemented.


    • username will be displayed on each message of corresponding agents if at least 3 users are in the room
    • system is used to show messages with a specific centered display

    Message states:

    • saved: true one checkmark
    • distributed: true two checkmarks
    • seen: true two blue checkmarks
        _id: 7890,
        content: 'message 1',
        sender_id: 1234,
        username: 'John Doe',

    Events API

    Event Params Fires when
    fetchMessages (1) { room, options } A user has scrolled on top to load more messages
    sendMessage { roomId, content, file (5), replyMessage (6) } A user has sent a message
    editMessage { roomId, messageId, newContent, file (5), replyMessage (6) } A user has edited a message
    deleteMessage { roomId, messageId } A user has deleted a message
    openFile { message, action } A user has clicked to view or download a file
    addRoom - A user clicks on the plus icon next to searchbar
    menuActionHandler (2) { roomId, action } A user clicks on the vertical dots icon inside a room
    messageActionHandler (3) { roomId, action, message } A user clicks on the dropdown icon inside a message
    sendMessageReaction { roomId, messageId, reaction, remove } A user clicks on the emoji icon inside a message
    roomInfo room A user clicks the room header bar
    textareaActionHandler (4) { roomId, message } A user clicks on custom icon inside the footer
    typingMessage { message, roomId } A user is typing a message

    (1) fetchMessages is triggered every time a room is opened. If the room is opened for the first time, the options param will hold reset: true (1) fetchMessages should be a method implementing a pagination system. Its purpose is to load older messages of a conversation when the user scroll on top

    (2) menuActionHandler is the result of the menuActions prop.
    When clicking a button from your menuActions array, menuActionHandler will give you the name of the button that was click. Then you can do whatever you want with it. Ex:

    menuActionHandler({ roomId, action }) {
      switch (action.name) {
        case 'inviteUser':
          // call a method to invite a user to the room
        case 'removeUser':
          // call a method to remove a user from the room
        case 'deleteRoom':
          // call a method to delete the room

    (3) messageActionHandler is the result of the messageActions prop.
    When clicking a message menu button from your messageActions array, messageActionHandler will give you the name of the button that was click and the corresponding message data. Then you can do whatever you want with it. Ex:

    messageActionHandler({ roomId, action, message }) {
      switch (action.name) {
        case 'addMessageToFavorite':
          // call a method to add a message to the favorite list
        case 'shareMessage':
          // call a method to share the message with another user

    (4) textareaActionHandler can be used to add an extra icon on the right of the textarea, and recieve an event when clicking it.

    (5) All file params contain: { blob, localURL, name, size, type }

    (6) replyMessage object is available when the user replied to another message by clicking the corresponding icon, and contains the message information that was clicked

    Using with Firestore

    Source code

    You can find the source code to implement a full featured chat app using Firebase/Firestore inside the demo folder.
    To test it using your own Firebase project:

    • Setup Cloud Firestore (to store users and rooms) and Realtime Database (to store users online status)
    • Clone this repository: git clone https://github.com/antoine92190/vue-advanced-chat.git
    • Inside demo/src/firestore/index.js file, replace the line const config = ... by your own Firebase config
    • Go inside demo folder and run npm run serve

    Data structure

    If you decide to use the same code as in the demo folder to create your chat app, you need to have a specific Firestore data structure.
    To help you get started, I added in demo/src/App.vue a method addData to initialize some data on your Firestore database.

    Users collection

    users: {
      USER_ID_1: {
        _id: 1,
        username: 'User 1'
      USER_ID_2: {
        _id: 2,
        username: 'User 2'
      USER_ID_3: {
        _id: 3,
        username: 'User 2'

    Rooms collection

    chatRooms: {
      ROOM_ID_1: {
        users: [1, 3]
      ROOM_ID_2: {
        users: [1, 2, 3]

    Messages collection inside a room document

    messages: {
      MESSAGE_ID_1: {
        content: 'My first message',
        sender_id: 2,
        timestamp: 'December 11, 2019 at 4:00:00 PM',
        seen: true

    Use as a Web Component

    Clone vue-advance-chat project

    git clone https://github.com/antoine92190/vue-advanced-chat.git

    Build it as a Web Component

    npm i && npm run build:wc

    Add Vue.js to your application

    <!-- index.html -->
    <script src="https://unpkg.com/vue"></script>

    Import the built minified component in your application

    Add vue-advanced-chat.min.js in your application files


    Import the vue-advanced-chat.min.js file you just added

    import './vue-advanced-chat.min.js'
