@npmcli/config

What is @npmcli/config?

@npmcli/config is a configuration management library for Node.js applications, particularly designed to handle npm's configuration needs. It allows you to load, manage, and manipulate configuration settings from various sources such as environment variables, command-line arguments, and configuration files.

What are @npmcli/config's main functionalities?

Loading Configuration

This feature allows you to load configuration settings from various sources. The `load` method initializes the configuration by reading from environment variables, command-line arguments, and configuration files.

const { Config } = require('@npmcli/config');
const config = new Config();
config.load().then(() => {
  console.log(config.get('someKey'));
});

Setting Configuration

This feature allows you to set configuration values programmatically. The `set` method is used to assign a value to a specific configuration key.

const { Config } = require('@npmcli/config');
const config = new Config();
config.set('someKey', 'someValue');
console.log(config.get('someKey'));

Saving Configuration

This feature allows you to save the current configuration state back to the configuration file. The `save` method writes the current configuration settings to the appropriate file.

const { Config } = require('@npmcli/config');
const config = new Config();
config.set('someKey', 'someValue');
config.save().then(() => {
  console.log('Configuration saved!');
});
