GNU ease.js can be downloaded in a variety of formats, depending on the environment in which it will be used. Releases are always stable and production-ready.
The tarball contains the full source code, combined files for debugging GNU ease.js itself, combined files for development using GNU ease.js, minified files for production, and scripts needed to rebuild. The production and development links contain the JavaScript files needed to run GNU ease.js, the latter being unminified to allow easily stepping through the code with a debugger.
You should verify the above files using their associated signatures to ensure that they have not been altered. This can be done by placing both files in the same directory and running the command:
$ gpg --verify file.sig
where file is the full filename, such as easejs-latest.tar.gz. If you do not have the public signing key, you may download it by running this command:
$ gpg --keyserver keys.gnupg.net --recv-keys 8EE30EAB
ease.js is available via npm for use with Node.js. Please be warned that package signature checks are not performed by npm.
$ npm install easejs
