Features

📦 nai add

Explicit install command for clarity:

nai add                # Interactive mode
nai add react vue      # Install specific packages
nai add vitest -D      # Install as devDependency
nai add react --peer   # Install as peerDependency
nai add zod -C prod    # Specify catalog

Use nai add when installing packages named update, remove, or catalog:

nai add update  # Installs the "update" package
nai update      # Runs the update command

📦 nai update (alias: nai up)

Check and update outdated packages:

nai update              # Check all packages for updates
nai update react lodash # Update specific packages
nai update -i           # Interactive mode - select packages to update

• Automatically detects outdated dependencies
• Respects catalog references - updates catalog entries when needed
• Interactive multi-select for choosing which packages to update
• Colorful summary showing old → new versions

🗂️ nai catalog

Browse catalogs and change dependency versions:

nai catalog        # Interactive catalog browser
nai catalog --list # List all catalogs with dep counts

• View all catalogs and their dependencies
• Select packages within a catalog
• Fetch available versions from npm
• Choose new version from a list of recent releases
• Updates catalog entries and runs install automatically

🗑️ nai remove (alias: nai rm)

Remove packages from dependencies:

nai remove              # Interactive - select packages to remove
nai remove react lodash # Remove specific packages
nai rm axios --clean-catalog # Also remove unused catalog entries

• Shows all dependencies across workspace packages
• Multi-select packages to remove
• Indicates which packages and dep types are affected
• Optional catalog cleanup with --clean-catalog
• Updates all relevant package.json files

Technical Details

src/npm.ts

New module providing npm registry interactions:

• getPackageVersions(packageName) - Fetch all available versions
• checkOutdated(deps, options) - Compare current versions with latest

UI/UX

All new commands follow the existing design patterns:

• Uses @clack/prompts for consistent interactive UI
• Colorful output with ansis
• Spinner feedback during network operations
• Summary confirmation before making changes

Test Plan

• [✅] Build succeeds
• [✅] nai --help displays all commands correctly
• [✅] nai add --help shows install options
• [✅] nai update --help shows update options
• [✅] nai remove --help / nai rm --help shows remove options
• [✅] nai catalog --help shows catalog options
• [✅] nai catalog --list lists catalogs correctly
• [✅] Command aliases (up, rm) work as expected

（以上就是具体描述，让AI总结的，指令我都试了一遍正常的，基本就是完善了一下基础功能，希望能够合并，谢谢）

1. I am developing the search.
2. This PR is too large. It should be broken down into separate features for submission?
3. Will these command names conflict with the package name?

Regardless, thank you for your help!
