# Re-applies the two patches better-sqlite3 needs to load correctly under
# nodejs-mobile (Node 12.19 / Android x86_64 emulator). Required after any
# fresh `npm install` in nodejs-assets/nodejs-project, since both patches
# target files inside node_modules.
#
# Usage: ./scripts/fix-better-sqlite3-android.sh
# Run from the mobile project root, after `npm install` has already built
# better-sqlite3 once via nodejs-mobile-gyp (so build/better_sqlite3.target.mk
# and the Release/ dir already exist).
