Usage

You can import it as a custom component:

<template>
  <chat-window
    :current-user-id="currentUserId"
    :rooms="rooms"
    :messages="messages"
  />
</template>

<script>
  import ChatWindow from 'vue-advanced-chat'
  import 'vue-advanced-chat/dist/vue-advanced-chat.css'

  export default {
    components: {
      ChatWindow
    },
    data() {
      return {
        rooms: [],
        messages: [],
        currentUserId: 1234
      }
    }
  }
</script>

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++) {
  rooms.push(res)
}
this.rooms = rooms

// DON'T DO THIS
for (let i = 0; i < res.length; i++) {
  this.rooms.push(res)
}

// DO THIS
this.rooms[i].typingUsers = [...this.rooms[i].typingUsers, typingUserId]

// DON'T DO THIS
this.rooms[i].typingUsers.push(typingUserId)

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

// AND DON'T DO THIS
this.rooms.push(room)

Follow the UI loading pattern by updating messagesLoaded prop every time a new room is fetched

fetchMessages({ room, options }) {
  this.messagesLoaded = false

  // use timeout to imitate async server fetched data
  setTimeout(() => {
    this.messages = []
    this.messagesLoaded = true
  })
}

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

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

(3) rooms-loaded must be set to true when all rooms have been loaded. Meaning the user cannot scroll to load more paginated rooms

(4) room-id can be used to load a specific room at any time

(5) load-first-room can be used to remove the default behaviour of opening the first room at initialization

(6) room-message can be used to add a default textarea value

(7) messages-loaded must be set to true when all messages of a conversation have been loaded. Meaning the user cannot scroll on top to load more paginated messages

(8) room-actions can be used to display your own buttons when clicking the dropdown icon of each room inside the rooms list.
You can then use the room-action-handler event to call your own action after clicking a button. Ex:

room-actions="[
  {
    name: 'archiveRoom',
    title: 'Archive Room'
  }
]"

(9) menu-actions can be used to display your own buttons when clicking the vertical dots icon inside a room.
You can then use the menu-action-handler event to call your own action after clicking a button. Ex:

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

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

message-actions="[
  {
    name: 'addMessageToFavorite',
    title: 'Add To Favorite'
  },
  {
    name: 'shareMessage',
    title: 'Share Message'
  }
]"

You can use built-in message-actions 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
  }
]"

(11) show-new-messages-divider can be used to show/hide the blue line divider between seen and unseen messages.

(12) show-footer can be used to hide the room footer. For example to prevent users to send any message or media.

(13) text-messages can be used to replace default i18n texts. Ex:

text-messages="{
  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...'
}"

(14) text-formatting 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 :text-formatting="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

(15) link-options can be used to disable url links in messages, or change urls target. Ex:

:link-options="{ disabled: true, target: '_self' }"

(16) responsive-breakpoint can be used to collapse the rooms list on the left when then viewport size goes below the specified width.

(17) single-room 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.

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

(19) accepted-files can be used to set specifics file types allowed in chat. By default, all file types are allowed: "*".

Example: set "accepted-files="image/png, image/jpeg, application/pdf" to allow JPG PNG and PDF files

(20) styles can be used to customize your own theme. You can find the full list here

styles="{
  general: {
    color: '#0a0a0a',
    colorSpinner: '#333',
    borderStyle: '1px solid #e1e4e8'
  },

  footer: {
    background: '#f8f9fa',
    backgroundReply: 'rgba(0, 0, 0, 0.08)'
  },

  icons: {
    search: '#9ca6af'
  }
}"

Props data structure

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

Rooms prop

rooms="[
  {
    roomId: 1,
    roomName: 'Room 1',
    avatar: 'assets/imgs/people.png',
    unreadCount: 4,
    index: 3,
    lastMessage: {
      content: 'Last message received',
      senderId: 1234,
      username: 'John Doe',
      timestamp: '10:20',
      saved: true,
      distributed: false,
      seen: false,
      new: true
    },
    users: [
      {
        _id: 1234,
        username: 'John Doe',
        avatar: 'assets/imgs/doe.png',
        status: {
          state: 'online',
          lastChanged: 'today, 14:30'
        }
      },
      {
        _id: 4321,
        username: 'John Snow',
        avatar: 'assets/imgs/snow.png',
        status: {
          state: 'offline',
          lastChanged: '14 July, 20:00'
        }
      }
    ],
    typingUsers: [ 4321 ]
  }
]"

If you add the index property, your rooms will be ordered using this value. index 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 lastChanged properties:
- state can be 'online' or 'offline'
- lastChanged 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 senderId field which holds the id of the corresponding agent. If senderId matches the currentUserId prop, specific UI and actions will be implemented.

Notes:

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

messages="[
  {
    _id: 7890,
    content: 'message 1',
    senderId: 1234,
    username: 'John Doe',
    avatar: 'assets/imgs/doe.png',
    date: '13 November',
    timestamp: '10:20',
    system: false,
    saved: true,
    distributed: true,
    seen: true,
    disableActions: false,
    disableReactions: false,
    file: {
      name: 'My File',
      size: 67351,
      type: 'png',
      audio: true,
      duration: 14.4,
      url: 'https://firebasestorage.googleapis.com/...',
      preview: 'data:image/png;base64,iVBORw0KGgoAA...'
    },
    reactions: {
      wink: [
        1234, // USER_ID
        4321
      ],
      laughing: [
        1234
      ]
    }
  }
]"

(1) fetch-messages 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) fetch-messages 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) fetch-more-rooms is triggered when scrolling down the rooms list, and should be a method implementing a pagination system.

(3) open-user-tag is triggered when clicking a user tag inside a message. When creating a user tag by typing @ in the footer textarea and sending the message, the tag will be identified with the below pattern:

<usertag>TAGGED_USER_ID</usertag>

This will make the tag clickable inside a message. Ex: message tag content
send-message and edit-message events will handle that pattern for you and pass it in the content param.

(4) room-action-handler is the result of the room-actions prop.
When clicking a button from your room-actions array, room-action-handler will give you the name of the button that was click. Then you can do whatever you want with it. Ex:

  switch (action.name) {
    case 'archiveRoom':
      // call a method to archive the room
  }
}

(5) menu-action-handler is the result of the menu-actions prop.
When clicking a button from your menu-actions array, menu-action-handler 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
  }
}

(6) message-action-handler is the result of the message-actions prop.
When clicking a button from your message-actions array, message-action-handler 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:

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 to <usertag>John</usertag>',
    senderId: 2,
    timestamp: 'December 11, 2019 at 4:00:00 PM',
    seen: true
  }
}

Notes

You need to create a composite index to order rooms by last message received. The easiest way to do it is to create a room, then click the error message url in the browser debugging console.
