sync-deps

TLDR; Compares your lockfile with installed dependencies and triggers an installation on mismatches. Works with npm, yarn and pnpm.

Tired of your local dev-server not starting after you checked out a branch that has different dependencies than you previous one? Normally you would have to manually update your dependencies. sync-deps can automate this step.

Based on your lockfile it automatically detects whether you use npm, yarn or pnpm and acts accordingly.

heavily inspired by this gist!

Usage

Install as devDependency (adds ~1MB to your node_modules): yarn add -D sync-deps

Option one: add as pre-hook of your dev task:

In this case sync-deps checks your dependencies before your dev server starts.

Example - in a NextJS environment:

1{
2  "scripts": {
3    "predev": "sync-deps",
4    "dev": "next dev"
5  }
6}

Option two: usage with husky on post-checkout

In this case sync-deps checks your dependencies, whenever you check out a different branch via git.

with yarn:

1yarn add -D husky
2yarn husky install
3yarn husky add .husky/post-checkout "sync-deps"

with npx:

1npm install husky --save-dev
2npx husky install
3npx husky add .husky/post-checkout "sync-deps"
