Configuration

Inside a command, this.config provides useful properties you can use in your command. Here are a list of its methods and properties:

• name - name of CLI
• version - version of CLI
• pjson - parsed and normalized CLI package.json
• bin - CLI bin name
• cacheDir - CLI cache directory
  • MacOS: ~/Library/Caches/mycli
  • Unix: ~/.cache/mycli
  • Windows: %LOCALAPPDATA%\mycli
  • Can be overridden with XDG_CACHE_HOME
• configDir - CLI config directory
  • Unix: ~/.config/mycli
  • Windows: %LOCALAPPDATA%\mycli
  • Can be overridden with XDG_CONFIG_HOME
• dataDir - CLI data directory
  • Unix: ~/.data/mycli
  • Windows: %LOCALAPPDATA%\mycli
  • Can be overridden with XDG_DATA_HOME
• dirname - dirname used with cacheDir|configDir|dataDir. Can be overridden in package.json.
• errlog - path to error log inside of cacheDir
• home - user home directory
• platform - operating system darwin|linux|win32
• arch - process architecture x64|x86
• shell - current shell in use
• userAgent - user-agent intended for http calls. example: mycli/1.2.3 (darwin-x64) node-9.0.0
• windows - boolean
• debug - set to 1 if debug is enabled (with ${BIN}_DEBUG=1 or DEBUG=$BIN). In the future this may be used for multiple debug levels.
• npmRegistry - current npm registry to use with the plugins plugin
• plugins - loaded plugins
• commands - all commands in CLI
• topics - all topics in CLI
• commandIDs - string IDs of all commands
• async runHook(event, opts) - trigger a hook

Custom User Configuration

Often it's useful to have a custom configuration for your users. One way to implement this is to read a config.json file from the CLI's config directory:

import {Command} from '@oclif/command'
import * as fs from 'fs-extra'
import * as path from 'path'

export class extends Command {
  async run() {
    const userConfig = await fs.readJSON(path.join(this.config.configDir, 'config.json'))

    this.log('User config:')
    console.dir(userConfig)
  }
}

To share this logic between different commands, use a base class.
