Tests included use Mocha. Use npm test to run the tests.

$ npm test

Notes

• You do not need to escape anything. This module will escape characters when necessary.
• This module is very fast but you might as well cache the output of xml() and serve it until something changes.

History

I started this module over two years ago (April 2011) because there weren't any Node modules for creating RSS. Besides these 25 modules I would love to know what other projects are using it.

Contributing

Contributions to the project are welcome. Feel free to fork and improve. I do my best accept pull requests in a timely manor, especially when tests and updated docs are included.
