Workspaces are an optional feature used by monorepos to split a large project into semi-independent subprojects, each one listing their own set of dependencies. The automated way also flattens the node_modules hierarchy and installs basic global dependencies like yarn itself. You can use the -D flag to indicate that youre adding devDependencies. Any project contains at least one workspace: the root one. Note there is a workaround for this by defining a different node linker.

In particular, this means two interesting things: You can write plugins that Yarn will load at runtime, and that will be able to access the true dependency tree as Yarn sees it; this allows you to easily build tools such as Lerna, Femto, Patch-Package, You can have a dependency on the Yarn core itself and instantiate the classes yourself (note that this part is still a bit experimental as we figure out the best way to include the builtin plugins when operating under this mode). We'll go over a popular use case for Yarn that is enhanced by Yarn 2: using workspaces to manage dependencies for your monorepo. Chiefly, using this approach will conflict with any packages that depend on reading files directly from their node_modules folder. Due to a particularity in how Yarn installs packages which list peer dependencies, some packages will be mapped to multiple virtual directories that don't actually exist on the filesystem. Check @pixi/workspaces-run 1.0.2 package - Last release 1.0.2 with MIT licence at our NPM packages aggregator and search engine. In particular he wrote the whole node_modules compatibility layer, which I can tell you is no easy feat! https://yarnpkg.com/getting-started/migration#switching-to-plugnplay.
