## What it does

The skill guides the agent through dependency updates in Node.js projects. First, it identifies the installed package version with `npm ls` and queries npm registry tags using `npm view`. Update flows differ by SemVer level. For patch and minor bumps, the agent runs `npm install` and verifies everything with `npm run build && npm test`.

Major releases get an in-depth migration pass. The agent searches for `CHANGELOG.md`, finds official upgrade guides, and inspects imports with `grep`. Code changes are applied file by file. Validation requires the whole suite: linting, type-checking via `npx tsc --noEmit`, unit tests, and the project build.

When automated codemods like `npx @next/codemod` exist, the skill prefers them over manual edits. In monorepos, updating a package in only one workspace breaks workspace consistency, so all workspaces must be updated together. The agent also inspects peer dependency warnings and records final changes in `package-lock.json`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill updating-npm-package -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/updating-npm-package/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/updating-npm-package/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill updating-npm-package -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill updating-npm-package -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/updating-npm-package/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

gemini skills install https://github.com/spencerpauly/awesome-cursor-skills --path resources/updating-npm-package
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/updating-npm-package/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add spencerpauly/awesome-cursor-skills --skill updating-npm-package -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/spencerpauly/awesome-cursor-skills/tree/HEAD/resources/updating-npm-package/SKILL.md

## When to use it
- Check available package versions and latest dist-tags on npmjs.com
- Identify breaking changes and upgrade guides for major version jumps
- Scan imports across the codebase to locate affected functions
- Verify the upgrade using linter, typecheck, tests, and build scripts

## Example prompts
- Update react to the latest version and run the tests
- Upgrade next to the latest major version and follow the migration guide
- Bump zod in package.json and fix breaking changes across the codebase

# Updating an npm Package

Use this skill when the user asks to update, upgrade, or bump a specific npm dependency.

## Steps

1. **Check the current version** — read `package.json` to find the installed version:

   ```bash
   npm ls <package-name>
   ```

2. **Find the latest version on npm** — fetch the package info:

   ```bash
   npm view <package-name> versions --json
   npm view <package-name> dist-tags --json
   ```

   This gives you the `latest` tag and all published versions.

3. **Determine the update type** — compare current version to latest:
   - **Patch** (1.2.3 → 1.2.4): bug fixes only
   - **Minor** (1.2.3 → 1.3.0): new features, backwards compatible
   - **Major** (1.2.3 → 2.0.0): breaking changes

4. **For patch or minor updates** — just do it:

   ```bash
   npm install <package-name>@latest
   ```

   Run the build and tests to make sure nothing broke:

   ```bash
   npm run build && npm test
   ```

   If everything passes, commit and report what changed.

5. **For major updates** — do a thorough investigation first:

   a. **Fetch the changelog and release notes** — check the package's GitHub repo for `CHANGELOG.md`, `MIGRATION.md`, or release notes. Use the web to find the official upgrade guide:

   ```
   Search: "<package-name> v<major> migration guide" OR "<package-name> v<major> upgrade guide"
   ```

   b. **Read the breaking changes** — identify every breaking change between the current and target version. Common things to check:
   - Removed or renamed APIs
   - Changed function signatures or return types
   - Dropped Node.js version support
   - New peer dependency requirements
   - Changed default behavior
   - Config file format changes

   c. **Scan the codebase for impact** — search for every usage of the package:

   ```bash
   # Find all imports
   grep -r "from ['\"]<package-name>" src/
   grep -r "require(['\"]<package-name>" src/
   ```

   For each usage, check if it's affected by a breaking change.

   d. **Apply the update**:

   ```bash
   npm install <package-name>@latest
   ```
