Inquirer.js is a library for building interactive command line user interfaces.
The library solves the problem of collecting structured input from users in terminal applications. It provides a collection of pre-built prompt types—including text input, multiple choice, checkboxes, password fields, and others—that handle the complexity of terminal interaction, validation, and formatting. Rather than building these interfaces from scratch, developers use Inquirer.js to chain together prompts that guide users through a series of questions and capture their responses in a structured format.
Inquirer.js suits projects that need to gather user input in the terminal, from simple CLI tools to complex configuration wizards. It works well for Node.js applications where interactive prompts improve user experience over static command-line arguments. The library is particularly valuable when you need consistent, polished prompt behavior across different terminal environments and want to avoid the low-level complexity of terminal control. Teams building CLI tools, scaffolding generators, or interactive setup flows should consider it as an alternative to building prompt logic manually or using lower-level terminal libraries.
The project maintains steady activity with regular commits addressing bug fixes and feature requests. Pull requests receive timely review and feedback from maintainers. Issues are actively triaged and responded to, indicating ongoing engagement with the user base. The codebase is written in TypeScript, providing type safety for developers integrating the library into their projects.
