Config utilities for the vlt client.

Usage · API

Overview

These are config utilities used by the vlt cli.

Usage

import { get, set, edit, list, del } from '@vltpkg/config'

// Assuming you have a LoadedConfig instance from @vltpkg/cli-sdk
// const conf = await loadConfig()

// Get a config value by key
const colorValue = await get(conf) // requires conf.positionals[1] to be the key name
// Supports dot notation for nested properties in record fields
// e.g., conf.positionals = ['get', 'registry.npmjs.org']

// Set config values using key=value pairs
// conf.positionals should contain pairs like ['set', 'color=auto', 'timeout=5000']
await set(conf)
// Creates config file if it doesn't exist when called with no pairs
// Supports dot notation for record fields: 'registry.npmjs.org=https://registry.npmjs.org/'

// Edit the config file with the configured editor
await edit(conf) // opens conf.get('config') file in conf.get('editor')

// List all current config values as key=value pairs
const allConfig = list(conf) // returns array of 'key=value' strings

// Delete config keys
// conf.positionals should contain keys to delete: ['del', 'color', 'timeout']
await del(conf) // removes specified keys from conf.get('config') file

API

get(conf: LoadedConfig)

• Retrieves a single config value by key
• Supports dot notation for accessing nested properties in record fields
• Returns the value as string | number | boolean | string[] | Record<string, string> | undefined
• Requires exactly one key in conf.positionals[1]

set(conf: LoadedConfig)

• Sets config values from key=value pairs in conf.positionals
• Creates an empty config file if no pairs are provided
• Supports dot notation for record fields (e.g., registry.npmjs.org=value)
• Writes to the config file specified by conf.get('config')

edit(conf: LoadedConfig)

• Opens the config file in the editor specified by conf.get('editor')
• Uses spawnSync to launch the editor with the config file path
• Throws an error if the editor command fails

list(conf: LoadedConfig)

• Returns all current config options as an array of 'key=value' strings
• Converts the internal config records to a flat list format

del(conf: LoadedConfig)

• Deletes specified config keys from the config file
• Requires at least one key in conf.positionals (after the command name)
• Removes keys from the file specified by conf.get('config')
