@battis/qui-cli v0.4.2

@battis/qui-cli

Quickly (get it?) build a CLI app

Install

npm i @battis/qui-cli

Usage

This is an ESM module that depends on other ESM modules, and so really can only feasibly be imported by ESM modules.

import cli from '@battis/qui-cli';

const args = cli.init();
const name = await cli.prompts.input({ message: 'What is your name?' });
cli.log.info(`Hello, ${name}.`);
const spinner = cli.spinner('Wait a sec');
setTimeout(() => spinner.stop(), 1000);

API

cli.init(config?: Partial<Options>)

All configs have default values or can be ignored

type Options = {
  env: {
    // application root, defaults to cli.appPath()
    root: string;

    // wwhether or not to load .env file
    // accepts boolean to load from `root` or path to .env file
    // default `true`
    loadDotEnv: boolean | string;

    // whether to set the process current working directory to `root`
    // default true
    setRootAsCurrentWorkingDirectory: boolean;
  };

  /**
   * CLI argument config as in jackspeak
   * @see https://github.com/isaacs/jackspeak#usage
   */
  args: {
    envPrefix: string;
    requirePositionals: boolean | number; // number of (or if) positional args required
    options: OptionsConfig; // jack.opt()
    optionLists: OptionListsConfig; // jack.optList()

    // default includes --help/-h and --commands
    flags: FlagsConfig; // jack.flag()
  };

  shell: {
    // display shell command stdout (default `true`)
    silent: boolean;

    // show cli.shell.exec() commands in console (default `false`)
    showCommands: boolean;
  };

  log: {
    // path to log file (default `undefined`)
    logFilePath?: string;

    // log level to display in stdout (default `info`)
    stdoutLevel: string;

    // log level to display in log file (default `all`)
    fileLevel: string;

    /**
