# Provide support for Node.js
#
# Feature:	nodejs
#
# Usage:	USES=nodejs[:args]
#   Valid args:
#   - build     use node as build-time dependency
#   - run       use node as runtime dependency
#   - env       set the environment (NODEJS_VERSION and NODEJS_SUFFIX)
#   - version   available version: lts, current, 16, 18, 20
#
# Note:
# - The supported versions follow upstream release schedule
#   https://github.com/nodejs/Release/blob/main/README.md#release-schedule
#   - lts is 18 now
#   - current is 20 now
# - USES=nodejs means USES=nodejs:build,run
# - If you define a version, you must provide run and/or build
