# Upload Uppy releases to Edgly.net CDN. Copyright (c) 2018, Transloadit Ltd.
#
# This file:
#
#  - Assumes EDGLY_KEY and EDGLY_SECRET are available (e.g. set via Travis secrets)
#  - Tries to load env.sh instead, if not
#  - Checks if a tag is being built (on Travis - otherwise opts to continue execution regardless)
#  - Installs AWS CLI if needed
#  - Assumed a fully built uppy is in root dir (unless a specific tag was specified, then it's fetched from npm)
#  - Runs npm pack, and stores files to e.g. https://transloadit.edgly.net/releases/uppy/v0.28.0/dist/uppy.css
#  - Uses local package by default, if [version] argument was specified, takes package from npm
#
# Run as:
#
#  ./upload-to-cdn.sh [version]
#
# To upload all versions in one go (DANGER):
#
#  git tag |awk -Fv '{print "./bin/upload-to-cdn.sh "$2}' |bash
