Package Exports

  • inquirer
  • inquirer/lib/prompts/base
  • inquirer/lib/prompts/confirm
  • inquirer/lib/prompts/input
  • inquirer/lib/prompts/list

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (inquirer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Inquirer.js Build Status

A collection of common interactive command line user interfaces.

Goal and philosophy

We strive at providing easily embeddable and beatiful command line interface for Node.js ; some hope in becoming the CLI Xanadu.

Inquirer should ease the process of asking end user questions, parsing, validating answers, and providing error feedback.

Inquirer provide the user interface, and the inquiry session flow. If you're searching for a full blown command line program utility, then check out Commander.js (inspired by) or Charm (used internally).

Documentation
