import { ChatClient, TokenProvider } from '@mlbd/chat-client'

const chatClient = new ChatClient({
  chatApiEndpoint: "https://my-chat-api",
  tokenProvider: new TokenProvider({
    // This is a POST request configuration for fetching chat token
    url: "https://my-api/auth/chat",
    getHeaders: () => {
      // Optional
      // return a headers object your endpoint requires
      return Promise.resolve({ Authorization: "Bearer <ACCESS_TOKEN>" })
    getBody: () => {
      // Optional
      // return a body object your endpoint requires
      return Promise.resolve({ key: "value" })
  pusherOptions: {
    appKey: '<PUSHER_APP_KEY>',
    cluster: '<PUSHER_APP_CLUSTER>',
    forceTLS: true

const myGroups = await chatClient.getMyGroups();

const messages = await chatClient.sendMessage({
  groupId: "<group_id>",
  message: "hello, world!",
  attachments: [{
    title: "Laika - the dog",
    mime_type: "image/jpeg",
    url: "https://domain/laika.jpeg"
  parentMessageId: "<parent_message_id>",

const group = await chatClient.getGroup("<group_id>");

Get message

const message = await chatClient.getMessage("<message_id>");

Search messages

const messages = await chatClient.searchMessages({
  keyword: "<search_keyword>",

  groupId: "<group_id>",
  // limit is optional, default: 10
  limit: 5,
  // offset is optional, default: 0
  offset: 5

limit and offset are to be used for pagination.

NPM scripts

  • npm t: Run test suite
  • npm start: Run npm run build in watch mode
  • npm run test:watch: Run test suite in interactive watch mode
  • npm run test:prod: Run linting and generate coverage
  • npm run build: Generate bundles and typings, create docs
  • npm run lint: Lints code
  • npm run commit: Commit using conventional commit style (husky will tell you to use it if you haven't :wink:)

Excluding peerDependencies

On library development, one might want to set some peer dependencies, and thus remove those from the final bundle. You can see in Rollup docs how to do that.

Good news: the setup is here for you, you must only include the dependency name in external property within rollup.config.js. For example, if you want to exclude lodash, just write there external: ['lodash'].

Automatic releases

Prerequisites: you need to create/login accounts and add your project to:

Prerequisite for Windows: Semantic-release uses node-gyp so you will need to install Microsoft's windows-build-tools using this command:

npm install --global --production windows-build-tools

Setup steps

Follow the console instructions to install semantic release and run it (answer NO to "Do you want a .travis.yml file with semantic-release setup?").

Note: make sure you've setup repository.url in your package.json file

npm install -g semantic-release-cli
semantic-release-cli setup
# IMPORTANT!! Answer NO to "Do you want a `.travis.yml` file with semantic-release setup?" question. It is already prepared for you :P

From now on, you'll need to use npm run commit, which is a convenient way to create conventional commits.

Automatic releases are possible thanks to semantic release, which publishes your code automatically on github and npm, plus generates automatically a changelog. This setup is highly influenced by Kent C. Dodds course on egghead.io

Git Hooks

There is already set a precommit hook for formatting your code with Prettier :nail_care:

By default, there are two disabled git hooks. They're set up when you run the npm run semantic-release-prepare script. They make sure:

This makes more sense in combination with automatic releases


Array.prototype.from, Promise, Map... is undefined

TypeScript or Babel only provides down-emits on syntactical features (class, let, async/await...), but not on functional features (Array.prototype.find, Set, Promise...), . For that, you need Polyfills, such as core-js or babel-polyfill (which extends core-js).

For a library, core-js plays very nicely, since you can import just the polyfills you need:

import "core-js/fn/array/find"
import "core-js/fn/string/includes"
import "core-js/fn/promise"
