Meant to be used via the [Swig CLI][1], just run:
swig install
Swig install does an npm install on dependencies and then copies those dependencies to a public folder to be served by the app. The default 'public' directory for apps is /web/APP-NAME/public but you can also specify a target directory for public assets e.g. the usual Scala play public folder can be 'target' or 'main/resources' etc.
For example:
swig install --public ~Code/web/web-mosaic/target/public
If you're fixing IE11 issues locally you may want to use the --transpile flag
during swig install. It adds a final step that transpiles all JS once it's
finished installing to /public/js. It's not needed on canary etc because the
minification step takes care of it.
E.g.
swig install --transpile
