    The codebase is written using the ESNext Specification (ECMAScript Stage 0), following the StandardJS Code Style

    ECMASript JavaScript Style Guide ESLint Babel JS Yarn

    We use:

    • Yarn to handle npm dependencies,
    • ESNext CLI to transform ESx code to ESNext,
    • Babel CLI to transpile ESNext code to node/browser compatible javascript,
    • And Standard CLI + ESLint to lint or format ESNext codebase.

    Global dependencies

    Get the latest node engine (example with nvm):

    $ nvm install lts/carbon

    Install yarn from npm (for development only):

    $ npm install --global yarn

    All the rest of the development dependencies are local.

    Clone and install

    Clone the repo and install dependencies:

    $ git clone
    cd generate-swap-project
    $ yarn install

    Running test

    Finally, run the test pipeline:

    $ yarn pipeline:test

    Develop in BDD mode

    B.D.D. means Behavior-Driven-Development

    The project is ready to code in BDD mode. Just run the bdd yarn command:

    $ yarn bdd

    The project will be lint, built, the BDD unit tests will be run, and the process will watch for any file changes to loop over the previous tasks (lint, build, test, watch).

    Releasing a new version

    The task yarn pipeline:build generate a ./dist folder in the repository's root directory but this folder is not part of the git repository (there is an entry in the .gitignore file). However the dist folder is included in the package.json#files field.

    Thus to release a new, lets say, "patch" version, just run:

    $ yarn release:patch

    The whole build pipeline is run locally (lint, transpile, test) and then a new git tag and a new npm tag are pushed up.
