Hello, Did you create a Salsa repo where you have started your work and uploaded sources? That will make it easier for others to contribute to the package.
Also, Yarn is not a minifier it's a package manager. AFAIK it can't be used during build. All dependencies must be Debian packages. There are many JS libs in Debian with the `libjs-` prefix. Probably some are missing, but I didn't check yet. Michel Le Bihan
