Examples
--------
Update the package 'webpack' to a specific version range:
update-dependency webpack ^4.0.0
Update all packages to the latest version, with a caret.
Only update if the update is substantial:
update-dependency --minimal --regex '.*' ^latest
Update all packages, that does not start with '@jupyterlab',
to the latest version and use the same version specifier currently
being used
update:dependency --regex '^(?!@jupyterlab).*' latest --dry-run
Print the log of the above without actually making any changes.
update-dependency --dry-run --minimal --regex '.*' ^latest
Update all packages starting with '@jupyterlab/' to the version
the 'latest' tag currently points to, with a caret range:
update-dependency --regex '^@jupyterlab/' ^latest
Update all packages starting with '@jupyterlab/' in all lerna
workspaces and the root package.json to whatever version the 'next'
tag for each package currently points to (with a caret tag).
Update the version range only if the change is substantial.
update-dependency --lerna --regex --minimal '^@jupyterlab/' ^next
