Your dependencies, naked.

Manage client-side dependencies with npm install, then import them by name — no bundler, no build step, no CDN.

No bundling, no transpilation

Neither your code nor your dependencies need a build step. Already transpiling? That works too.
Local-first

Your dependencies are served from your own domain. No external requests, no CDN, no extra points of failure.
Granular cache busting

Versioned directory names give you CDN-grade caching. Updating one module leaves every other module cached.
Self regenerating, sans watcher

npm lifecycle hooks keep everything up to date as dependencies change. Nothing to start, nothing to watch.
The web is not just JS

Stable, unversioned URLs for CSS, images, fonts and other package assets that can’t go through an import map (yet).
Even the edge cases

Dynamic import(), import.meta.resolve(), CJS packages, local packages, git dependencies, npm aliases, npm workspaces all work.

Three steps, then forget it’s there

Install Nudeps once per project
```
npx nudeps install
```
This adds Nudeps to your devDependencies and gives your package.json two scripts: dependencies, so Nudeps re-runs itself every time you npm install or npm uninstall, and prepare, so a fresh clone is ready too. No watcher to start, nothing to remember.
Add the import map to your HTML
```
<script src="/importmap.js"></script>
```
One classic <script>, before any module scripts. Nudeps keeps the file up to date; the tag never changes.
Install dependencies like you always have
```
npm install vue
```
Nudeps copies vue and everything it depends on to client_modules/, in versioned directories that cache like a CDN, and adds them to the import map.

That’s it. Bare specifiers now work in the browser, served from your own domain:

import { createApp } from "vue";

No bundler, no build step, no CDN. See it running in the demos, or read the full walkthrough.

I ran the npx command and added the import map to my app, but I assumed that there was still a lot more work to do. I was shocked to realize I was done.

Nudeps is how I want to build for the web. It helps make sure my time is spent adding features, rather than wrangling build steps.
