Preproc.js

Preproc.js is the anything preprocessor for node.js. Preprocess any file performing inclusions and conditional compilation.

Installation

npm install preproc

Usage

Include everything everywhere

//= include "mylib.coffee"
 
MyLib.doSomething();

Define delimiters for each file format and choose how to transform sources before they are included into other files

var preproc = require('preproc');
 
var builder = new preproc.Builder({
  types: {
    coffeescript: {
      delimiters: ["#="],
      extensions: ['.coffee'],
      to: {
        javascript: function(content) {
          return coffee.compile(content, {
            bare: true
          });
        }
      }
    },
    javascript: {
      delimiters: ["//="],
      extensions: ['.js'],
      to: {
        javascript: function(content) {
          return ";" + content + ";";
        },
        coffeescript: function(content) {
          return "\`" + content + "\`\n";
        },
        html: function(content) {
          return "<script>\\\\<![CDATA[\n" + content + "\n\\\\]]></script>";
        }
      }
    },
    html: {
      delimiters: ["<!--=", "-->"],
      extensions: ['.html']
    }
  }
});

<body>
<!--= include "templates/*.hbs" -->
