How can I compile ES6 code to ES5 for the browser?

I have installed traceur using npm and have managed to compile a simple ES6 script. My problem is that the code that is generated is specific to node.js

I know that traceur can be run from the browser but I wanted to optimise further. Is There a way to run traceur from the command line (node) in similar way to how lesscss works?

Solution

  • I might be a bit late to the party, and you already found the solution as mentioned in your comment, but still I want to give an answer to make it easier for others to find the solution.

    It's possible to compile your ES6 code with adding --script to your command.

    Compile a single file

    $ traceur es6-code.js --script es5-code.js

    Compile multiple files to a single file

    $ traceur --out es6-code-1.js es6-code-2.js es6-code-3.js --script es5-code.min.js
