    Javascript Frontend Greenfield Boilerplate (IE10+)

    this project includes:

    Everyone loves to start new projects. This repo is a blank, new frontend project just for us! It's an amalgamation of best practises for how to setup and organize a project. You don't have to use it in your projects in this way, but it is recommended - it makes easier for developer onboarding.

    Getting Started

    Prerequisites: Install Docker and git. You might also want to install node.js, but this not stricly needed. For Mac: Install Docker for Mac (Stable Channel Don't install the older docker-machine. For Linux: Install Docker Engine Community Edition. You'll also need to separately install docker-compose

    To run it:

    • git clone
    • cd testable-reactions to go into the project folder
    • docker-compose up --build to build and run it

    The "app" is then available at http://localhost:4080

    To use it as a template for your projects:

    • in package.json change package, name, and author

    The entry point on your new app is ./src/index.js, which is called by ./index.html.

    Folder Structure Convention

    src: main source code. Don't use app, even though that is comnon for React apps. src works for backend services and even Java projects!

    dist: final generated files for production usage (target folder for Java projects).

    test: all tests, with subfolders for unit, visual or any other folders for different types of tests

    docker: anything related to docker. We used to have docker-compose.yml also in this folder, but it has moved to the root folder, as this is how docker-compose works more elegantly.

    Scripts convention

    Scripts, standardized across repos

    available scripts:

    script description
    build builds the dist files
    prettier runs prettier
    start starts the dev server on whatever port is defined in ./variables
    test runs all tests except the e2e tests
    test:e2e runs the end-to-end tests
    test:e2e:debug runs the end-to-end tests in debug mode
    test:lint checks the js and jsx files for js and code style error
    test:lint:fix checks the js and jsx files for js and code style error and fixes them if able
    test:style checks the css files for style errors
    test:style:fix checks the css files for style errors and fixes them if able
    test:type runs flow to test the typing
    test:unit runs a quick unit test
    test:unit:coverage runs a unit test that determines test coverage and reports in the browser
    test:unit:coverage:cli runs a unit test that determines test coverage and reports in the command line
    test:visual runs visual regression tests
    test:visual:debug runs visual regression tests with visual and console debug output
    test:visual:baseline builds the project and copies the files to be served on test time
    test:visual:clean removes old visual test images and the baseline. then generates a new baseline
    test:visual:cli runs visual regression tests

    you can run script from the docker container is already running by doing either of these:

    • login to container with docker-compose exec testable-reations bash and the run scripts from within container with npm run --silent <script>
    • run any script directly via docker-compose exec testable-reactions npm run --silent <script>.

    to run them from docker, when a the docker container is already running: Either login to container with docker-compose exec testable-reations bash and the run scripts from within container with npm run --silent <script> or run any script directly via docker-compose exec testable-reactions npm run --silent <script>.

    Testable-Reactions - Code of Conduct


    Please report issues here.

    • add any specific information that can help to reproduce and resolve the bug.
      • What did you do, when the bug appeared.
      • Node, NPM, + version number
      • OS, Browser + version, resolution
    • Add a label to the issue, if possible.
      • critical -> needs fix right away (like broken build, blocks development)
      • bug -> needs fix
      • issue -> small bug, does not affect anything (small bug in UI, design issue)
      • feature -> feature request
      • question -> needs discussion
      • docs -> needs documentation
      • help wanted -> need help with implementation or fixing bug

    Included package details


    React is a JavaScript library for building user interfaces.


    Redux is a predictable state container for JavaScript apps. It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test.


    Babel transforms your JavaScript

    ES2015 and beyond Babel has support for the latest version of JavaScript through syntax transformers. These plugins allow you to use new syntax, right now without waiting for browser support.


    Packs CommonJs/AMD modules for the browser. Allows to split your codebase into multiple bundles, which can be loaded on demand. Support loaders to preprocess files, i.e. json, jade, coffee, css, less, ... and your custom stuff.


    A lightweight containerization tools. Main benefits to use it: Total freedom to choose whatever compiler/interpreter version you want, No need to install dependencies on dev machine, Same code in dev and production, Easy orchestration of multiple microservices.

    Docker Intro

    Docker Ports

    When mapping ports from container to host in the docker-compose.yml file like this

          - 4080:4080

    the host port (first number) needs to be choosen wisely. It needs to be unique for all services running on one host, and since we run services on clusters, there can be a multitude of services. Only ports in the range from 4000 to 9999 are allowed due to Security Groups.


    NYC instruments your ES5 and ES2015+ JavaScript code with line counters, so that you can track how well your unit-tests exercise your codebase.


    Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub.


    Nightmare is a high-level browser automation library.


    Perceptual diffing suite built on Nightmare


    Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.

    Enzyme's API is meant to be intuitive and flexible by mimicking jQuery's API for DOM manipulation and traversal.


    Standalone test spies, stubs and mocks for JavaScript. No dependencies, works with any unit testing framework.


    Coveralls works with your CI server and sifts through your coverage data to find issues you didn’t even know you had before they become a problem.


    ESLint is an open source project originally created by Nicholas C. Zakas in June 2013. Its goal is to provide a pluggable linting utility for JavaScript.


    A mighty, modern CSS linter that helps you enforce consistent conventions and avoid errors in your stylesheets.


    Flow is a static type checker for your JavaScript code. It does a lot of work to make you more productive. Making you code faster, smarter, more confidently, and to a bigger scale.


    Prettier is an opinionated code formatter.
