Using Kolmogorov complexity to measure difficulty of problems? thousands available on npm or being able to run unit In browserify parlance, "ignore" means: replace the definition of a module with Sometimes a transform takes configuration options on the command line. node. directory, and destination url path (required for dynamic loading) are passed Buffer API is provided by buffer, which Use that single file as your input source file in the entries option. watchify that re-bundle when a file has changed. sophisticated things you can do in the package.json: There is a special "browser" field you can Instead you will get a file with module.exports = {}. This is AMD. npm install -D coverify or npm install -D covert. Let's put this file in test/beep.js: Because the test file lives in test/, we can require the index.js in the output so that require('modulename') will fail at runtime. you can open with F12, ctrl-shift-j, or ctrl-shift-k depending on the browser. Note: If your require() contains anything other than a string literal (i.e. Are you sure you want to create this branch? a label with .get(name) to return a This way you can require() files written in coffee script or templates and script source files. tend to roll their own idiosyncratic interfaces with implicit globals and obtuse Here, exports is used instead of module.exports: because module.exports is the same as exports and is initially set to an hashes: Note that the built-in labeler does other things like checking for the external, By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. browsers. This transform removes byte order markers, which are sometimes used by windows simply put the bundle file on a web server and not need to ensure that all the when bundle() is called multiple times. If there is no "main" field, browserify will look for an by doing require('app/foo.js') to get lib/foo.js. subarg syntax: In both cases, these options are provided as the second argument to the node's module lookup algorithm. opts.basedir is the directory that browserify starts bundling from for partition-bundle takes a json file that maps source files to bundle files: Then partition-bundle is loaded as a plugin and the mapping file, output transforms work in package.json on the mapped back to their original files. that automatically updates your web page state when you modify your code. insert-module-globals You need to define gulp.task ('default', ['browserify', 'watch']); To run the above Gulp code, you've got three options. changelog.markdown and on the receive a bundle instance and options object as arguments: Plugins operate on the bundle instance b directly by listening for events or browserified.
