npm-fast-sync v1.2.1

npm-fast-sync

Incremental npm install with downgrade support.

This script is a much faster alternative to npm install when you want to keep your node_modules folder up to date.

It will upgrade/downgrade all modules in dependencies and devDependencies that do not satisfy the semver spec. This also works for git dependencies that are tagged with the version number like so:

git+ssh://git@github.com/private-company/private-module.git#3.2.1

Installing

npm install -g npm-fast-sync

Usage

Just run npm-fast-sync and this script will take care of the rest!

cd ~/my/node/project
npm-fast-sync

Technical details

• The script will first run npm prune to clean out unused dependencies.
• For each dependency in dependencies and devDependencies, it will evaluate if the installed version satisfies the spec.
• All the unsatisfied dependencies are collected together with their specs into a single npm install command. For example if the no-op and lodash modules need updating: npm install no-op@1.0.0 lodash@^3.0.0.
