Traceur provides support for Googles Traceur project which adds many enhanced features to the JavaScript language. For full details on what all Traceur does, visit http://code.google.com/p/traceur-compiler/wiki/LanguageFeatures
Version 2.0 of this package has transitioned effort to be a compiler and not a runtime loader. It still works just the same as a runtime loader, just really, DONT DO IT!
Traceur should only be installed globally to your developer system and never be included as part of your package. The Traceur syntax transformer is way too slow to use in a live system and should only be used as a compiler/tester.
- Install with NPM:
npm install traceur -g
Visit Traceur website as linked above for language features.
Traceur module provides 2 binaries:
traceur app.js:
This binary will execute node but all require() statements can make use of
traceur syntax. Note that startup will be slow as the source code is transformed!
This is the same thing as calling require('traceur') then requiring your file.
DO NOT USE THIS FEATURE IN A PRODUCTION APP!
traceurc inputdir/ outputdir/: this command takes a directory and finds every
.js file in the directory and compiles it with traceur then writes it in the same
dir format as input, to the output dir. A small runtime library is created at
outputdir/node_modules/traceur-runtime.js that is auto loaded by all modules.
You may need to add this to your package.json so npm wont ignore it... (I hate that addition to npm :())
USE THIS FEATURE TO DEPLOY/PUBLISH!
