hoisting (Yarn)#

An optimization provided by Yarn. By default JavaScript packages will directly include dependencies inside their local node_modules. By hoisting we're "lifting" these inner dependencies to the top level node_modules directory, and thus optimize the generated bundles. In case two dependencies have conflicting version dependencies of the same library, the hoisting will not be possible (for that conflicting dependency) and you'll see multiple instances of the same library in the bundle, or you'll see that the add-on receives its own node_modules folder.

mrs-developer#

Also called "missdev", a tool similar to buildout's mr.developer. It automatically downloads and keeps up to date copies of software and add-ons under development based on definitions stored in mrs.developer.json. As a byproduct of its update operations, it also automatically adjusts jsconfig.json, which is used by Volto to configure webpack aliases.

mxdev#

mxdev [mɪks dɛv] is a utility that makes it easy to work with Python projects containing lots of packages, of which you only want to develop some. It is designed for developers who use stable version constraints, then layer their customizations on top of that base while using a version control system. This design allows developers to override their base package constraints with a customized or newer version.
