Switch between different .npmrc files with ease and grace.


If you use a private npm registry, you know the pain of switching between a bunch of different .npmrc files and manually managing symlinks. Let that be a problem no more! npmrc is here to save the day, by making it dead simple to switch out your .npmrc with a specific named version. It also tries to protect you from your own stupid self by making sure you don't accidentally overwrite an .npmrc that you actually want to keep.


npm install -g npmrc


➜  ~  npmrc --help


  Switch between different .npmrc files with ease and grace.

  npmrc                 list all profiles
  npmrc [name]          change npmrc profile (uses fuzzy matching)
  npmrc -c [name]       create a new npmrc profile called name
  npmrc -r [registry]   use an npm mirror

Available mirrors for npmrc -r:
  au      - Australian registry mirror
  eu      - European registry mirror
  cn      - Chinese registry mirror
  default - Default registry


Calling npmrc without arguments creates an ~/.npmrcs/ directory if it doesn't exist, and copies your current ~/.npmrc as the 'default' .npmrc profile.

➜  ~  npmrc
Creating /Users/conrad/.npmrcs
Making /Users/conrad/.npmrc the default npmrc file
Activating .npmrc 'default'

Create a new .npmrc profile

➜  ~  npmrc -c newprofile
Removing old .npmrc (/home/rvagg/.npmrcs/default)
Activating .npmrc 'newprofile'

A blank profile will be created. To point your profile to a non-default registry:

➜  ~  npm config set registry

Then use npm adduser or npm login to authenticate with the new profile.

List available .npmrc profiles

➜  ~  npmrc 
Available npmrcs:
* default

Switch to a specific .npmrc

➜  ~  npmrc work
Removing old .npmrc (/Users/conrad/.npmrcs/default)
Activating .npmrc 'work'

You can also pass only the first few characters of a profile and npmrc will autocomplete the profile's name.

➜  ~  npmrc def
Removing old .npmrc (/Users/conrad/.npmrcs/work)
Activating .npmrc 'default'

npmrc <name> will also go to some lengths to make sure you don't overwrite anything you might care about:

➜  ~  npmrc default
Removing old .npmrc (/Users/conrad/.npmrcs/work)
Activating .npmrc 'default'
➜  ~  npmrc default  
Current .npmrc (/Users/conrad/.npmrc) is already 'default' (/Users/conrad/.npmrcs/default)
➜  ~  rm ~/.npmrc
➜  ~  touch ~/.npmrc
➜  ~  npmrc default
Current .npmrc (/Users/conrad/.npmrc) is not a regular file, not removing it
➜  ~  rm ~/.npmrc
➜  ~  npmrc default
Activating .npmrc 'default'

Note For Windows Users

You may have to run npmrc in a shell (cmd, PowerShell, Git Bash, etc) with elevated (Administrative) privileges to get it to run.

Environment Variables

  • NPMRC_STORE - Path to directory of profiles. Default: ~/.npmrcs/

For your convenience, you can change registries easily using the -r flag. Currently we provide aliases for:
