[node.js] How to restore/reset npm configuration to default values?

I have played with npm set and npm config set for several times, now I want to reset to default values (a kind of factory reset).

Does npm provide a command to do that? or Should I delete all configuration files by hands then reinstall it?

I need it both on linux Centos and on Windows 8.

Thanks in advance!

For what it's worth, you can reset to default the value of a config entry with npm config delete <key> (or npm config rm <key>, but the usage of npm config rm is not mentioned in npm help config).

Example:

# set registry value
npm config set registry "https://skimdb.npmjs.com/registry"
# revert change back to default
npm config delete registry

If it's about just one property - let's say you want to temporarily change some default, for instance disable CA checking: you can do it with

npm config set ca ""

To come back to the defaults for that setting, simply

npm config delete ca

To verify, use npm config get ca.

Config is written to .npmrc files so just delete it. NPM looks up config in this order, setting in the next overwrites the previous one. So make sure there might be global config that usually is overwritten in per-project that becomes active after you have deleted the per-project config file. npm config list will allways list the active config.

1. npm builtin config file (/path/to/npm/npmrc)
2. global config file ($PREFIX/etc/npmrc)
3. per-user config file ($HOME/.npmrc)
4. per-project config file (/path/to/my/project/.npmrc)

If you run npm config edit, you'll get an editor showing the current configuration, and also a list of options and their default values.

But I don't think there's a 'reset' command.

npm config edit

Opens the config file in an editor. Use the --global flag to edit the global config. now you can delete what ever the registry's you don't want and save file.

npm config list will display the list of available now.
