A browserify transform to remove server-side code.

What

I needed a convenient way to implement server-side only code within my current browserify processes and didn't like the other available options. This will transform "process.browser" into "true" and then statically evaluate all conditional expressions.

Installation

Npm

npm install isbrowser

Usage

browserify input.js -t isbrowser -o output.js

Example Input

var env;

if (process.browser) {
    env = 'browser';
} else {
    env = 'node';
}

env = process.browser ? 'browser' : 'node';

env = process.browser && 'browser';

env = process.browser || 'server';

Example Output

(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
var env;

{
    env = 'browser';
}

env = 'browser';

env = 'browser';

env = true;
},{}]},{},[1])
