es6-templates

Compiles JavaScript written using template strings to use ES5-compatible syntax. For example, this:

var name = "Nicholas",
    msg = `Hello, ${name}!`;

console.log(msg);    // "Hello, Nicholas!"

compiles to this:

var name = "Nicholas",
    msg = "Hello, " + name + "!";

console.log(msg);    // "Hello, Nicholas!"

For more information about the proposed syntax, see the TC39 wiki page on template strings.

Install

$ npm install es6-templates

Usage

$ node
> var compile = require('es6-templates').compile;
> compile('`Hey, ${name}!`')
{ 'code': ..., 'map': ... }

Without interpolation:

`Hey!`
// becomes
'"Hey!"'

With interpolation:

`Hey, ${name}!`
// becomes
"Hey, " + name + "!"

With a tag expression:

escape `<a href="${href}">${text}</a>`
// becomes
escape(function() {
  var strings = ["\u003Ca href=\"", "\"\u003E", "\u003C/a\u003E"];
  strings.raw = ["\u003Ca href=\"", "\"\u003E", "\u003C/a\u003E"];
  return strings;
}(), href, text);

Or work directly with the AST:

$ node
> var transform = require('es6-templates').transform;
> transform(inputAST)

Transforming ASTs is best done using recast to preserve formatting where possible and for generating source maps.
