rclnodejs-cliBuild Status

Standalone commandline tools and ros2 cli extension for use with the ROS2 rclnodejs client library.

  • create-package
  • generate-ros-messages

Prerequisites

  • ROS2 Foxy or greater including the colcon build tools
  • Node.js versions 14.0-19.X
  • npm or yarn package manager
  • A shell environment that includes ROS2. See Configuring a ROS2 Environment for more info.

Installation

Install the rclnodejs-cli package globally or alternatively use npx to run rclnodejs-cli directly from a shell.

Note: Your shell environment should include ROS2.

To install rclnodejs-cli globally run the following command from a shell:

  npm install -g rclnodejs-cli

Optional

You can extend the ros2 cli with additional commands and options from this package by sourcing the `install/setup.[bat,bash,ps1,sh] file.

On Linux run:

  source <rclnodejs-cli-dir>/install/setup.bash

On Windows run:

  <rclnodejs-cli-dir>\install\setup.bat
or
  <rclnodejs-cli-dir>\install\setup.ps1

For more information on using an rclnodejs-cli tool from the ros2 cli see the references to tool/command user-guides below.

Commands

create-package command

The rclnodejs-cli create-package command creates a hybrid ROS2-Nodejs package that can coexist and participate with other ROS2 packages in a ROS2 workspace and be run using the ROS2 launch facility. A ROS2-Nodejs package consist of a ROS2 package, specifically an ament-cmake ROS2 package, overlaid with a Nodejs package.

Learn more about the create-package tool.

generate-ros-messages command

Generate JavaScript messages corresponding to the interfaces (.IDL) in your ROS2 environment. Run this command from the root folder of a Nodejs package that includes rlcnodejs as a dependency. The JavaScript message files are created in the node_modules/rclnodejs/generated/ folder of the current Nodejs package.
