build-examples-from-local.sh

# ./build-examples-from-local.sh <example-to-clean-install>
# Example usage:
# ./build-examples-from-local.sh examples/react-nextjs-seafowl
#
# This is a hacky script to build packages, publish them to local Verdaccio, then
# install all the examples with the latest built packages. Note that this will
# result in a temporary sha for each package being in examples/yarn.lock, which
# does not refer to a public package, so nobody else will be able to install the
# examples if you check it in with those shas.
#
# When you're done developing locally, or after you've published new versions of
# packages to npm, you can build the examples from npm by running the counterpart
# to this script, ./build-examples-from-npm.sh
