### Description

npm gets its config settings from the command line, environment
variables, `npmrc` files, and in some cases, the `package.json` file.

See [npmrc](/configuring-npm/npmrc) for more information about the npmrc files.

See [config](/using-npm/config) for a more thorough discussion of the mechanisms
involved.

The `npm config` command can be used to update and edit the contents
of the user and global npmrc files.

### Sub-commands

Config supports the following sub-commands:

#### set
```bash
npm config set key value
```
Sets the config key to the value.

If value is omitted, then it sets it to "true".

#### get
```bash
npm config get key
```

Echo the config value to stdout.

#### list
```bash
npm config list
```

Show all the config settings. Use `-l` to also show defaults. Use `--json`
to show the settings in json format.

#### delete
```bash
npm config delete key
```

Deletes the key from all configuration files.

#### edit
```bash
npm config edit
```

Opens the config file in an editor.  Use the `--global` flag to edit the
global config.
