I had the problem to move over all existing packages from my existing Node Red installation to another so I created a python script which may be useful for similar cases. (Maybe there are better solutions, if so let me know):
Arguments:
0: file path to package.json
1: file / name / path where to put the output (shell install script)
2: optional to remove the version string and replace with latest: --noversion
Python3:
import json
import argparse
def extract_packages(package_json_path):
with open(package_json_path, 'r') as f:
package_data = json.load(f)
dependencies = package_data.get('dependencies', {})
dev_dependencies = package_data.get('devDependencies', {})
packages = dict(**dependencies, **dev_dependencies)
return packages
def generate_shell_script(package_json_path, output_script_path, use_latest_version):
packages = extract_packages(package_json_path)
with open(output_script_path, 'w') as f:
f.write('#!/bin/bash\n')
f.write('npm install \\\n')
for package_name, package_version in packages.items():
if use_latest_version:
f.write('\t{}@latest \\\n'.format(package_name))
else:
f.write('\t{}@{} \\\n'.format(package_name, package_version))
f.write('\n')
print('Shell script generated: {}'.format(output_script_path))
if __name__ == '__main__':
parser = argparse.ArgumentParser(description='Generate a shell script to install Node.js packages from a package.json file')
parser.add_argument('package_json_path', help='Path to the package.json file')
parser.add_argument('output_script_path', help='Path to the output shell script file')
parser.add_argument('--noversion', action='store_true', help='Install the latest version of the packages')
args = parser.parse_args()
generate_shell_script(args.package_json_path, args.output_script_path, args.noversion)
usage example:
pi@raspberrypi3A:~/PackageExtractor $ python3 extract.py package.json ../.node-red/gogo.sh --noversion
