🚀 Install

npm i -D npm-multi-publish

🚦 Quick Setup

  1. Open package.json
  2. Add npm-multi-publish to the prepublishOnly and postpublish hooks
  3. Convert publishConfig into an array of configs

      "scripts": {
+         "prepublishOnly": "npm-multi-publish",
+         "postpublish": "npm-multi-publish"

      "publishConfig": [
+         {
+             "registry": "Registry URL 1"
+         },
+         {
+             "registry": "Registry URL 2"
+         },
+         ...


If using Lerna, add this configuration to the respective package.json of each package in the monorepo (not necessary in the root package.json).

That's it! Next time you run npm publish or yarn publish it will automatically publish to all registries configured in your package.json publishConfig array.

If the registries require authentication, make sure you authenticate with them all using a single .npmrc file (toggling via npmrc will not work).

💁‍♀️ FAQ

Is it possible to authenticate to multiple npm registries with one .npmrc file?

Yes. This is actually the preferred way because npm publish loads the .npmrc file at the beginning, so toggling .npmrc files via npmrc during publish (even in npm-multi-publish) does not take effect.

To login to an enterprise/custom registry:

$ npm login --registry=

To verify authentication on a specific registry:

$ npm whoami --registry=

A .npmrc file authenticated with multiple registries should include something like this:

//registry-a-url/:_authToken=... # Registry A authentication token
//registry-b-url/:_authToken=... # Registry B authentication token

If you have certs for the respective registries, you can add multiple certs to your .npmrc file.

How can I test publishing to a registry?

Use verdaccio to create a local mock npm registry.

Install and start the verdaccio server:

$ npm i -g verdaccio
$ verdaccio # Start server

In a separate terminal window, configure npm to use your verdaccio server. I recommend using npmrc to create a new npmrc for the "verdaccio" profile so your default npmrc isn't polluted and so you can switch to it easily in the future:

$ npmrc -c verdaccio # (Optional) Create a new .npmrc not to pollute existing ones
$ npm set registry http://localhost:4873 # Set default registry
$ npm adduser --registry http://localhost:4873 # Login to registry

Now you can test publishing.

After your package is test-published to verdaccio, you can confirm the contents via their Web UI at http://localhost:4873 (or any other port it's listening on).
