async function main() {

  await rclnodejs.init();
  const node = rclnodejs.createNode('messager');
  const pub = node.createPublisher('std_msgs/msg/String', 'message');
  const timer = node.createTimer(1000, () => {
      const msg = 'hello world: ' + Date.now();
      //alternatively using type aliased messages
      // const msg: std_msgs.msg.String = {
      //  data: 'hello world (std_msg)'
      // }

rclnodejs v0.10.1

This version has been verified with ROS 2 Dashing Diademata Patch Release 2.

Feature Added

• Support to pass the timeout parameter when starting to spin, which may reduce the CPU overhead potentially. #472 e.g.

rclnodejs.spin(node, -1);  // Waits until something happens.

• Support to define the default value of wstring, e.g.

wstring wstring_value_default1 "Hello world!"

Others

• Update the CI configurations and dependencies.

rclnodejs v0.10.0

This is the very first version which starts to support - ROS 2 Dashing Diademata verified on #494, and there is still some issue which fails the AppVeyor on Windows 10 and I have submitted an issue to track it. Hopefully, all bots will pass when it gets resolved.

Feature Added

• Some API updates to make the module can work properly on Dashing
• Support default value in .msg file, e.g. here
• Support wstring (https://design.ros2.org/articles/idl_interface_definition.html)

Others

• Update the doc links in README file #449

• Illustrate the relationship between rclnodejs versoins and ROS 2.0 releases #459

rclnodejs v0.8.0

• Add the support of Context #442

rclnodejs v0.7.1

Bug Fix

• Fix the build error due to the changes of rcl_wait_set_add_* #433

rclnodejs v0.7.0

Feature Added

• Add Clock/ROSClock class support.
• Add TimeSource class support, which enables you to attach Clocks to it and update them by receiving the topic of builtin_interfaces/msg/Time.

Improvements

• As the maximum safe integer in JavaScript is (2^53 - 1) due to double-precision floating-point format numbers specified in IEEE_754, the int64_t cannot be represented in JavaScript. We are going to use the string format of the integer for Time and Duration when exceeding the limitation, e.g.

let time = new Time(0, '9007199254740992'); // time.nanoseconds equals  '9007199254740992'

let duration = new Duration(0, '9007199254740992'); // duration.nanoseconds equals  '9007199254740992'

rclnodejs v0.6.1

Release Note

• This patch release fixed a problem which caused by the new error handling API #429
