React-Trello-Multiboard is a single-page application built with React displaying multiple cards of several Trello® boards and lists. The cards can be filtered by preferred team members.

Table of Contents

Main features

  • 📝 flexible multiboard configuration (eg. select multiple lists to display from multiple boards)
  • 🏢 optimised teamwork experience, (eg. send deeplinks to your colleagues with their stories already filtered)
  • 🚪 add private (accessible only to invited members of the Board) and public Trello boards
  • 🔒 your data stays secure in your browser and is not shared with others
  • 🔨 built with awesome technologies, like: react 16.x, react-router-dom, redux, material-ui and styled-components (to name a few)
  • 📦 Small package size thanks to webpack and size-limit
  • 💪 There's more to come. 😀



As you can see in the example, there are three Trello® boards and two members. From each board all cards of a list matching the #sprint1 pattern in the title (can be any pattern, defined in config.js) is listed below. Each member can be selected, which causes the list of cards to only show those of the selected member. Additionally, you see five sprints on the page. You can select one sprint and see the cards of the selected pattern. This allows you to plan ahead.

You can find the example in the gif above here:

Development & Build Requirements

GitHub stars GitHub forks GitHub issues Twitter

  node v8.9.x
  npm 5.6.x

  // or

Switch to the required version with nvm use. If you have not installed this node version, install it with eg. nvm install v8.9.4.

Full Example Setup with nvm

  // first install nvm (eg. with brew)
  brew install nvm

  // then install the required node version
  nvm install v8.9.4

  // and the required npm version (if you have not npm 5.6.x)
  npm install -g npm@5.6.0

  // finally use the just installed versions
  nvm use

Setup & Configuration Quickstart

Trello API Key

Log in to Trello and get your api key here:


First install all Dependencies with

  yarn // or npm install


Once you have installed all dependencies, yarn/npm will copy ./config/config.example.js for you and rename it to ./config/config.js. You then have to customize it according to your needs and eg. enter your API key and other settings into the config.js.

module.exports = {
  app_title: 'Multiboard for Trello®',
  api_key: 'your_api_key',
  google_analytics_property: 'UA-12345678-9',
  company_member: 'exampleusername'
  preferred_members: /exampleusername|anotheruser/,
  lists: [/#sprint1/, /#sprint2/, /#sprint3/],
  boards: [
      shortcut: 'hw',
      name: 'hello-world',
      id: 'board-1',
      estimates_with_round_brackets: true,
      estimates_with_square_brackets: true,

The main config properties look like this:

  • app_title: name that appears in the Menubar and website title
  • api_key: your trello api key
  • google_analytics_property: your Google Analytics property
  • company_member: representing the company and available on all cards, because this user is used to calculate the company estimations when all members are toggled
  • preferred_members: usernames of the ones you want to highlight, filter and calculate the estimations from. Note: currently the app can only display preferred members and not all of the found ones
  • lists (array with regex strings): search pattern of the list name(s) you want to get tasks from
  • boards: array of board configs

The list of boards should contain board objects like this:

  • shortcut (string): the title above each list of tasks
  • name (string): name of trello board
  • id (string, optional): id of trello board, only required when board is public but user should see it
  • estimates_with_round_brackets (bool)
  • estimates_with_square_brackets (bool)

With the id property you can add boards, which are public and the user is not part of when accessing your TrelloMultiBoard App.

How to get the id of your board?

Let's assume the url of your board looks like this: You can get the id of the board now by changing the url to: Wait for some time (depends on the number of lists and card of the board) and you should see a result similar to

 { "id": "IGVA5wQ67w2mBbkctLxi", "name": "hello-world", "desc":"", ... }

The id at the beginning of the JSON is the id of the board.

Estimations Configuration

Additionally you can calculate and get the estimations from the cards, if their name looks similar to: "Setup server (3)[1]". Now you can turn the feature on by adding one of the following boolean flags to the board' config.

  • estimates_with_round_brackets (bool)
  • estimates_with_square_brackets (bool)

Each of the values will be summed up by their type.


  • Board name: Example-Board
  • Card 1: "Setup server (3)[1]"
  • Card 2: "Upload docker imge (3)[0]"

Would result in the following total estimation for the board: Example-Board (6)[1]

Google Analytics & Privacy Page

It is possible to integrate Google Analytics with pageviews by simply adding google_analytics_property to the config.js. This will add to the app and track pageviews. By default doNotTrack browser settings are respected.

At the same time a privacy page (eg. http://localhost:2222/#/privacy) is created and a CookieNotice presented to new users. The content can be defined in src/pages-content by adding a file.

By default gaOptout is available to set a disable Google Analytics cookie in the user's browser.

One can use it like this in the file:

Or you deactivate it with a DoNotTrack Cookie: <a href="javascript:gaOptout();">Deactive Google Analytics</a>.

URL Shortcuts & Bookmarks

Certain url links can be used to eg. customize the inital lists and selected member:

How to start the App locally

Now, when you have set up the config.js start the app with: yarn start. The webpack-dev-server will start the app and open: http://localhost:2222/#/.

You can now interact with the board, filter members or show all cards again.

How to build the App for Production

yarn start will build and run a development version of the app, but you should create a stable and production ready build with yarn build before you upload the files onto your server.

The output will be available in the dist folder.

How to develop and contribute

Clone the repository, commit your changes and create a PR for new features, bugfixes or other ideas.

List of npm scripts and git hooks

The following scripts are available (also work with npm run):

  • yarn analyse: bundles the production build and analyses it with Jarvis, see other analyse here.
  • yarn lint: lints the js-code with Eslint (without --fix)
  • yarn lint:scss: lints the scss-code with Stylelint (without --fix)
  • yarn start: starts the app with the webpack-dev-server
  • yarn test: runs tests with jest
  • yarn test:watch: runs tests with jest in watch mode
  • yarn test:coverage: runs tests with jest and creates a coverage report
  • yarn test:verbose: runs tests with jest in the verbose mode

Pre-Commit Hooks

When attempting to commit and push changes, some taks will automatically run:

  • JavaScript files (.js):

    • runs eslint and prettier and formats the code
    • runs all related tests of the committed files with jest
  • Scss files (.scss):

    • runs stylelint and formats the code

Pre-Push Hooks

Runs all tests with Jest.
