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

(5) 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:

menuActions="[
  {
    name: 'inviteUser',
    title: 'Invite User'
  },
  {
    name: 'removeUser',
    title: 'Remove User'
  },
  {
    name: 'deleteRoom',
    title: 'Delete Room'
  }
]"

(6) 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:

messageActions="[
  {
    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.

messageActions="[
  {
    name: 'replyMessage',
    title: 'Reply'
  },
  {
    name: 'editMessage',
    title: 'Edit Message',
    onlyMe: true
  },
  {
    name: 'deleteMessage',
    title: 'Delete Message',
    onlyMe: true
  }
]"

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

textMessages="{
  NEW_MESSAGES: 'Nouveaux messages',
  MESSAGE_DELETED: 'Ce message a été supprimé',
  MESSAGES_EMPTY: 'Aucun message',
  CONVERSATION_STARTED: 'La conversation a commencée le :',
  TYPE_MESSAGE: 'Taper votre message',
  SEARCH: 'Rechercher'
}"

(8) 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```

Output:

This is
multiline code

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

(10) 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.

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

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

styles="{

Props data structure

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

Rooms prop

rooms="[
  {
    roomId: 1,
    roomName: 'Room 1',
    lastMessage: {
      content: 'Last message received',
      sender_id: 1234,
      username: 'John Doe',
      timestamp: '10:20',
      date: 123242424,
      seen: false,
      new: true
    },
    users: [
      {
        _id: 1234,
        username: 'John Doe',
        status: {
          state: 'online',
          last_changed: 'today, 14:30'
        }
      },
      {
        _id: 4321,
        username: 'John Snow',
        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

  • 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.

Note: username will be displayed on each message of corresponding agents if at least 3 users are in the room.

messages="[
  {
    _id: 7890,
    content: 'message 1',
    sender_id: 1234,
    username: 'John Doe',
    date: '13 November',
    timestamp: '10:20',
    seen: true,
    disable_actions: false,
    disable_reactions: false,
    file: {
      name: 'My File',
      size: 67351,
      type: 'png',
      url: 'https://firebasestorage.googleapis.com/...'
    },
    reactions: {
      wink: [
        1234, // USER_ID
        4321
      ],
      laughing: [
        1234
      ]
    }
  }
]"

Events API

Event Params Fires when
fetchMessages (1) { room, options } A user has scrolled on top to load more messages
sendMessage { roomId, content, file (4), replyMessage (5) } A user has sent a message
editMessage { roomId, messageId, newContent, file (4), replyMessage (5) } A user has edited a message
deleteMessage { roomId, messageId } A user has deleted a message
openFile { message } 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
typingMessage { message, roomId } A user is typing a message
roomInfo { room } A user has clicked the room header bar

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

(5) 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:

  • 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
  }
}
