Commander is a complete solution for Node.js command-line interfaces. It simplifies building command-line tools with automatic help generation, option parsing, and subcommands. Define commands, options with short and long flags, and arguments declaratively. Commander handles parsing user input, displays help messages, and validates required parameters, making command-line application development faster and more maintainable.
Commander.js releases were frequent in 2011-2012, then slowed significantly. Releases became more sporadic, with occasional bursts. There were periods with no releases lasting many months. The latest release was in May 2025 (version 14.0.0). No releases were made in the last three months.
Commander's npm package downloads show a generally increasing trend from March 2024 to July 2025, peaking in July 2025 at 968 million downloads. However, August 2025 saw a decrease, and September 2025 downloads are significantly lower, likely due to the month being incomplete.
