[UDI] Configure UDI images to allow `npm install -g` within workspaces
Is your enhancement related to a problem? Please describe
Some node projects rely on packages installed from npm/yarn, e.g. gulp. Currently, the UDI images used by default in workspaces do not necessarily have all required packages installed, and provide no easy means of installing them -- npm install -g in workspaces fails with a permissions error attempting to write to /usr/local/lib/node_modules.
Describe the solution you'd like
We probably don't want to pre-install every possible dependency in the container itself, but we can enable installing dependencies within workspaces by configuring npm and yarn to use writeable directories:
- ~/.npmrc
prefix=/projects/.node_modules_global - ~/.yarnrc
prefix "/projects/.yarn_global"
Then adding PATH=$PATH:/projects/.node_modules_global/bin/:/projects/.yarn_global/bin/ should allow using npm install -g <package> or yarn global add <package> in workspaces.
Describe alternatives you've considered
Alternatively, another writeable path, outside the shared /projects directory could be used. This would mean that installed modules do not use workspace storage, but also means that installed packages are lost when the workspace restarts.
