Traceur for node
This project provides an up to date version of the Traceur module for node, originally by @aikar. Changes have been made to account for API updates to Traceur over the past year.
Installation is pretty straight-forward. To globally install, just use:
$ sudo npm install -g
Quick start (binaries)
Once installed, you can
require("traceur") easily and then:
- Create a parser tree using
- Compile using
- or do whatever else you need to with Traceurs APIs
The traceurc node binary is an excellent example of how to consume Traceur from node, demonstrating file compilation, capturing the output from Traceur which can then be written anywhere you wish and more.
You can also use Traceur to consume modules with ES6 syntax as follows:
require("traceur"); var Foo = require('./foo.js'); var instance = new Foo; instance.bar();
To compile a directory using a binary with
require() for the Traceur runtime:
traceurc input output
e.g to compile the examples provided simply run:
traceurc examples/example2 examples/output2
Note: this is not the same as simply using the command-lines tools Traceur comes with. See bin/traceurc.
Usage (from original project)
Traceur module provides 2 binaries:
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.
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 won't ignore it.
