Bundle any node package into a standalone package. At work, we need to be able to install node modules without network access. I decided to write a tiny script that bundles any npm package and all its dependencies into a TGZ that can be installed without access to the npm registry.

pushd "node_modules/$pkg"

node <<EOF
var fs = require('fs');
var json = JSON.parse(fs.readFileSync('$file'));
json.bundleDependencies = Object.keys(json.dependencies);
fs.writeFileSync('$file', JSON.stringify(json));
EOF

bundle=`npm pack`

popd

popd

mv "$tmpdir/node_modules/$pkg/$bundle" "$bundle"

echo
echo "created $bundle"

rm -rf "$tmpdir"
