I found the answer myself, it should be: class Dog extends Animal say: () -> super console.log “Hello from dog called #{ @name }”
Compiling CoffeeScript into JavaScript usually results in JS that is fairly readable. You can convert snippets on the fly on the “Try CoffeeScript” tab of the CoffeeScript homepage, or via the CoffeeScript command line tool. There are also tools like decaffeinate that convert CoffeeScript source to modern JavaScript. If you know JavaScript and just want … Read more
This should do the trick: listener.listen(80).on(‘error’, function(err) { }); What listener.listen actually does is create a HTTP server and call listen on it: app.listen = function(){ var server = http.createServer(this); return server.listen.apply(server, arguments); };
If you want to continue with the next loop iteration, you want return, not continue, as what you’re passing to each is a function.

You don’t need to add files to the original src, but rather to use coffee only “if”… So, use gulp-if gulp.task(‘task’, function() { gulp.src(‘./stuff/*’) .pipe(gulpif(/[.]coffee$/, coffee())) .pipe(gulp.dest(‘./dist/’)); }); See here more about gulp-if.
You can use any javascript testing framework with CoffeeScript. This will be testing the Javascript that CoffeeScript outputs which is necessary since CoffeeScript itself can’t be executed. Writing your own testing framework for CoffeeScript is fun (I did) but entirely uneccessary. UPDATE: Jasmine tests can be run on node.js in which case both the tests … Read more
