How can I configure options using the traceur module on nodejs

How do I configure options using the traceur module on nodejs. I'm doing the following but it doesn't seem to work.

require('traceur').require.makeDefault(function(filename) {

    // don't transpile our dependencies, just our app
    return filename.indexOf('node_modules') === -1;

});

traceur.options.annotations = true;

require('./start.js');

traceur.options.annotations = true is not resulting in annotations being enabled in traceur

node.js
ecmascript-6
traceur

Answer 1

Pass the options as the second argument to makeDefault:

require('traceur').require.makeDefault(function(filename) {
    // don't transpile our dependencies, just our app
    return filename.indexOf('node_modules') === -1;
}, {annotations: true});

See https://github.com/google/traceur-compiler/blob/master/src/node/require.js#L58
