OpenDDS module for Node.js

Requirements:

• OpenDDS (http://www.opendds.org) and its dependencies must be installed.
• Make sure all of the OpenDDS development environment variables are set before running npm to install this module. If you use the OpenDDS configure script, these variables can be set using "setenv.sh" or "setenv.cmd" depending on your platform.
  • The OpenDDS development environment can use either the source tree or the installed tree (the one created by "make install").
  • If using the installed tree, set the DDS_ROOT environment variable using the installed dds-devel.sh script.
  • If using security, you may need to ensure that OpenDDS is built with the same version of OpenSSL used by Node.js

Tested platforms:

• Node LTS versions 8, 10, 12, 14, 16, 18, 20
• Linux (Ubuntu 20.04) x86_64 using gcc 9.4.0
• Linux (Ubuntu 22.04) x86_64 using gcc 11.2.0 (w/ openssl-1.1.1q)
• Windows (Server 2022) x86_64 using Visual Studio Enterprise 2022
• macOS (11.7) x86_54 using clang 13.0
• Other OpenDDS-supported platforms should work, but may required changes to binding.gyp

Building and running the tests

• In OpenDDS directory:

  $ source setenv.sh

• In node-opendds directory:

  $ npm install
  $ mwc.pl -type gnuace
  $ make
  $ cd test
  $ ./run_test.pl

To build the module (for development of this module, users can simply use npm)

$ node-gyp configure build

Version 0.1.0

• Add support for publishing from Node.js

Version 0.0.9

• Support building this module using an installed OpenDDS

Version 0.0.8

• Requires at least OpenDDS 3.13. It will not build with older versions of OpenDDS.
• Added support for Security-enabled versions of OpenDDS.
• Compatibility with Node.js version 10 and NAN 2.10.

Version 0.0.7
