 ## rclnodejs-cli
 
 [rclnodejs-cli](https://github.com/RobotWebTools/rclnodejs-cli/) is a companion project we recently launched to provide a commandline interface to a set of developer tools for working with this `rclnodejs`. You may find `rclnodejs-cli` particularly useful if you plan to create ROS 2 node(s) and launch files for working with multiple node orchestrations.

 ### IDL Message Generation
 
 In addition to the standard ROS2 message generation (`.msg`, `.srv`, and `.action`), rclnodejs provides advanced support for generating JavaScript message files directly from IDL (Interface Definition Language) files. This feature is particularly useful when working with custom IDL files or when you need more control over the message generation process.
