ext-packager is a utility to package directories or zip files into EXT extensions.
npm install @extpkg/packagerext-packager keygen [-k privateKeyFile] [-f]
Generate a new private key and save it to a file in PKCS#8 PEM format. If the private key file is not specified, private.pem is used by default. To override any existing private key files use the -f option.
ext-packager pack <sourcePath> [-k privateKeyFile] [-o destFile] [-f]
Package and sign an extension with the specified private key. The source path can be a file or a directory. If the private key file is not specified, private.pem is used by default. If the destination file is not specified, the output file is created in the parent directory of the source path with the basename of the source path and .ext file extension. To override any existing destination files use the -f option.
