3Box Chatbox Plugin 💬

3box-chatbox-react node package is a drop-in react component that provides Web3 developers with a readymade chat system for their Ethereum application. Easily add rich, decentralized social discourse to your dApp with one line of code. The 3Box Chatbox plugin is built using 3Box infrastructure, and handles all logic for creating a chatbox. Starting with v0.1.0, Chatbox supports likes for every message. Read the docs on docs.3box.io.

How it Works

Architecture

The Chatbox plugin is built using a standard implementation of Open Threads which are defined in the 3Box Threads API and made available via the 3Box.js SDK. Chatbox messages are ephemeral and are persisted only as long as there is at least one user in the chatbox. The Chatbox plugin includes UI for inputting and displaying both an in-window and pop-up chat and all relevant logic. The component is configurable to various authentication patterns, and can handle both Web3/3Box logged-in & logged-out states.

Authentication

Starting with version 0.0.5, the content of the configured chatbox can be read right on component mount. Authentication into the space provided is handled automatically when the user decides to post to the chatbox.

Getting Started

  1. Install the component
  2. Choose your authentication pattern
  3. Configure application settings
  4. Usage

1. Install the component

npm i -S 3box-chatbox-react

2. Choose your authentication pattern

Depending on when and how your dApp handles authentication for web3 and 3Box, you will need to provide a different set of props to the component. Three acceptable authentication patterns and their respective props are discussed below in A-C:

A) Dapp handles web3 and 3Box logins, and they run before component is mounted. (recommended)

Dapp integrates with 3Box.js SDK and the 3box-chatbox-react component. In this case, the box instance returned from Box.openBox(ethAddr) via 3Box.js should be passed to the box prop in the chatbox component. The user's current Ethereum address should be passed to the currentUserAddr prop to determine which messages are their own.

B) Dapp handles web3 and 3Box logins, but they haven't run before component is mounted. (recommended)

Dapp integrates with 3Box.js SDK and the 3box-chatbox-react component. In this case, the login logic implemented in the dapp should be passed to the Chatbox component as the loginFunction prop, which is run when a user attempts to post a message. The user's current Ethereum address should be passed to the currentUserAddr prop to determine which messages belong to that user.

C) Dapp has no web3 and 3Box login logic.

Dapp only integrates with the 3box-chatbox-react component, but not 3Box.js SDK. All web3 and 3Box login logic will be handled within the Chatbox component, though it's required for the ethereum object from your dapp's preferred web3 provider be passed to the ethereum prop in the component.

Best practice

For the best UX, we recommend implementing one of the following authentication patterns: A; B; or B with A.

Each of these patterns allow your application to make the box object available in global application state where it can be used by all instances of the Chatbox component regardless of which page the user is on. This global pattern removes the need for users to authenticate on each chatbox component, should you decide to have more than one, which would be the case in C.

3. Configure application settings

First, choose a name for your application's 3Box space.

Although you are free to choose whichever name you'd like for your app's space, we recommend using the name of your app. If your application already has a 3Box space, you are welcome to use that same one for the chatbox.

Next, choose a naming convention for your application's threads.

The Chatbox thread needs a name, and we recommend that your application creates threadNames according to a simple rule. We generally like using a natural identifier, such as community name, page URL, token ID, or other similar means.



4. Usage

Example

import ChatBox from '3box-chatbox-react';

const MyComponent = ({ handleLogin, box, ethereum, myAddress, currentUser3BoxProfile, adminEthAddr }) => (
    <ChatBox
        // required
        spaceName="mySpaceName"
        threadName="myThreadName"


        // Required props for context A) & B)
        box={box}
        currentUserAddr={myAddress}

        // Required prop for context B)
        loginFunction={handleLogin}

        // Required prop for context C)
        ethereum={ethereum}

        // optional
        mute={false}
        popupChat
        showEmoji
        colorTheme="#181F21"
        currentUser3BoxProfile={currentUser3BoxProfile}
        userProfileURL={address => `https://mywebsite.com/user/${address}`}
        spaceOpts={}
        threadOpts={}
        agentProfile={
            chatName: "3Box",
            imageUrl: "https://imgur.com/RXJO8FD"
        }
        openOnMount={false}

        // enable Persistent Thread
        persistent
        // open
        firstModerator={"0xF439..."}
        // moderators={["0xp83F..."]}
        // members={["0xp83F...", "0xu9i7..."]}
    />
);

Prop Types

Property Type Default Required Case Description
spaceName String Always Likely your dApp name and / or chatbox category. A single spaceName with different threadNames is common practice when building a dApp with multiple Chatbox threads.
threadName String Always A name specific to this Chatbox.
box Object A (and likely B) The box instance returned from running await Box.openBox(address, web3) somewhere in your dApp.
currentUserAddr String (Ethereum Address) A & B The current user's Ethereum address. Passing this will be used to check which messages belong to the current user and can be used for fetching their 3Box profile to render in the Chatbox input UI.
loginFunction Function B A function from your dApp that handles web3 and 3Box login at the global dApp state. This callback will run when a user attempts to join the Chatbox but a box instance doesn't yet exist. Running this function should result in a box instance (from const box = Box.openBox(address, web3)) being passed as the box prop to this component.
ethereum Object window.ethereum C The ethereum object from whichever web3 provider your dApp uses. The enable method on this object will be used to get the current user's Ethereum address and that address will be used to openBox within the current Component context.
popupChat Boolean False Optional A boolean - true - to configure a pop up style chatbox with a button fixed to the bottom right of the window to pop open the chat UI. False will render the component in whichever container you have implemented.
agentProfile Object { chatName: 'Chatbox', imageUrl: null } Optional An object with the name of the chatbox which will appear in the Join thread step and in the header of the chat UI. The default imageUrl is the provided chat icon.
spaceOpts Object Optional Optional parameters for threads (see Docs.3box.io for more info)
threadOpts Object Optional Optional parameters for threads (see Docs.3box.io for more info)
colorTheme String/Boolean False Optional Pass an rgb or hex color string to match the color theme of your application
mute Boolean False Optional Pass false to turn off sound for incoming messages.
showEmoji Boolean False Optional Pass false to turn off the emoji pop up within the chat input UI.
currentUser3BoxProfile Object Optional If the current user has already had their 3Box data fetched at the global dApp state, pass the object returned from Box.getProfile(profileAddress) to avoid an extra request. This data will be rendered in the Chatbox input interface.
userProfileURL Function Defaults to returning user's 3Box profile URL Optional A function that returns a correctly formatted URL of a user's profile on the current platform. The function will be passed an Ethereum address within the component, if needed. A user will be redirected to the URL returned from this function when clicking on the name or Ethereum address associated with the message in the chatbox. This prop is also used in the "Edit profile" link in the header of the Chatbox component.
openOnMount Boolean False Optional Set whether a Popup style Chatbox is open on component mount. This prop only affects desktop browsers.
persistent Boolean False Optional Use persistent thread if set to true.
open Boolean False Optional Make the persistent thread open and anyone can post. If set to False, only members can post.
firstModerator Eth Address Optional The first moderator in persistent thread. This field is important to find the exact thread.
members Array of Eth Address Optional When the thread is private (open is false), add the provided members into the thread. Ignored if the thread is public.
moderators Array of Eth Address Optional When the thread is private (open is false), set the provided moderators for this thread. Ignored if the thread is public.
onLoad({messages, likes, thread}) Function Optional The callback function which is called when the chat messages are loaded for the first time. The chat history of messages and likes, and the thread object will be returned
onUpdate({messages, likes, thread}) Function Optional The callback function which is called when messages arrive. The messages and likes contains all the messages and likes
onError Function Optional The callback function which is called when failed to send message to the chat. Parameters of (error, data, showError) will be sent to onError. error is the error thrown when failed, data contains the info membership data, and showError is the function to show error message which accepts message as its parameter
