ECL v4 - Europa Component Library

The Europa Component Library (ECL) is a library of components applicable to all European Commission and European Union websites. The library contains all available components which you can use to build your website.

All library elements are accompanied with

documentation: what the component is intended for and recommendations regarding its usage
demo: visual representation of the component
code: technologically agnostic HTML/CSS code and twig implementation

Requirements

ECL is currently using node 20.9.0 (LTS), we recommend using this version (nvm use) to ensure the compatibility with all the ECL dependencies or the ones defined by the ECL Builder.

⚠️ pikaday

ECL uses Pikaday and this library is not bundled anymore by ECL. Therefore pikaday needs to be loaded or bundled by the application or website using ECL, depending on the needs, it is only required when a datepicker instance is present in a webpage. Additionally, when customising the date format used by the datepicker, in order to get a consistent output, moment.js is also needed. These scripts can be loaded from a CDN or fetched from the respective npm packages or websites for then hosting them locally. The order of the scripts should be:
