browserify-exec v0.0.2

browserify-exec

browserify inliner for shell commands at build time.

This module is a transform for browserify to allow you to execute shell commands at build time and inline the results into your bundle.

Install

npm install browserify-exec

Example

example/main.js:

var exec = require('browserify-exec');

var date = exec('date' + ' | xargs echo -n');
var hashObjectForThisFile = exec('git hash-object ' + __filename);

console.log(date);
console.log(hashObjectForThisFile);

And in the command line:

$ browserify -t browserify-exec example/main.js > bundle.js

You will see this in the bundle:

var date = "Fri Mar 18 11:36:36 EDT 2016";
var hashObjectForThisFile = "c1e51983f9fba8ef1ab17b58e868fe77ac6a9dc2\n";

Or you can use the API of browserify:

var browserify = require('browserify');
var b = browserify('example/main.js');
b.transform('browserify-exec');
b.bundle().pipe(fs.createWriteStream('bundle.js'));

Usage

browserify-exec builds on top of static-module so to use it, you first need to require the module by

var exec = require('browserify-exec')

Then you can use exec anywhere by passing in a command line string to execute. The result will be inlined and will replace the exec call. You also have access to filename and dirname variables in the arguments to exec.
