Determines if a program exists in the PATH environment variable. Cross platform, including support for checking likely executable file extensions on Windows. Available in synchronous and asynchronous versions. Thorough unit tests included.
npm install haz
Here's a synchronous example:
var haz = ;if// Great, use spawn to run imagemagick's convert
And here's an asynchronous example with a callback:
var haz = ;;
If you don't pass a callback, it behaves synchronously. Simple, right?
The tests convince
haz that is running in a realistic Windows environment for the Windows tests, and do the same for the Linux/Unix/MacOS/whatever tests.
About P'unk Avenue and Apostrophe
haz was created at P'unk Avenue for use in many projects built with Apostrophe, an open-source content management system built on node.js. (You don't need Apostrophe to use
haz.) If you like
haz you should definitely check out apostrophenow.org. Also be sure to visit us on github.
