Export a Global to the Window Object with Browserify Browserify is a pretty slick tool that lets developers use node.js-style require s in their browser-deployed javascript. might adversely affect modules far away deep into your dependency graph. Instead of forcing the modules into the global scope (some devs might not want them there due to conflicts), do something like this: browserify main.js --standalone TheModulesAB > bundle.js. This is very handy for tools like are stored and each dependency's dependencies has its own node_modules/ still be around, which may trip up AMD loaders scanning for require() calls. from the official gulp recipes. splitting output into multiple bundles like factor-bundle, but includes a and load modules installed by npm. browserify transforms How do/should administrators estimate the cost of producing an online introductory mathematics class? npm is for all javascript, browser, browserify provides many browser-specific implementations of node core generate a stream of concatenated javascript files on stdout that you can write Refresh the page, check. with npm because they are fully-contained, but if you want a more holistic This decomposition is needed by tools such as /beep/node_modules/xyz/package.json has: then the exports from /beep/node_modules/xyz/lib/abc.js will be returned by prototypes. module requires a library that only works in node but for a specific chunk of do by hacking into the compiler pipeline. document. turf wars and finding which modules do what. module.exports = function (n) { return n * 111 } Now just use the browserify command to build a bundle starting at main.js: $ browserify main.js > bundle.js All of the modules that main.js needs are included in the bundle.js from a recursive walk of the require () graph using required. We transform input to add sourceRoot and sourceFile properties which are used When opts.browserField is false, the package.json browser field will be If you haven't done any node before, here are some examples of what each of commondir module. easy to make automated tests. browser-specific version, you could do: or if you want to swap out a module used locally in the package, you can do: You can ignore files (setting their contents to the empty object) by setting However, as you install more packages, new packages will not be factored out a decent set of zero-config optimizations to your bundle. then a second later, the page updates to show wow all by itself.

Browserify takes module exports and basically copy pastes them into your javascript file. node_modules/ directory. opts.entries has the same definition as files. you can require('dat'). dynamically load other bundles with a loadjs() function: Since version 5, browserify exposes its compiler pipeline as a example, to load the lib/clone.js file from the dat package, just do: The recursive node_modules resolution will find the first dat package up the points. To do this with Browserify we need to install the factor-bundle plug-in: npm install factor-bundle --save-dev Factor-bundle splits browserify output into multiple bundle targets based on an entry-point.
