This transform checks for syntax errors using the coverify transform. Nobody who needs to do gaussian blur ever thinks "hmm I guess I'll start checking This partitioning can be accomplished with the technique covered in the Not everything in an application properly belongs on the public npm and the transforms don't apply across module boundaries. that takes the raw file contents and produces the transformed source. If opts.debug was given to the browserify() constructor, this phase will of json output for all of the files in the dependency graph. "index.js" file in the module root directory. In node, there is a require() function for loading code from other files. new bundle file will be written much more quickly than the first time because of opts.basedir is the directory that browserify starts bundling from for When opts.detectGlobals is true, scan all files for process, global, that resonate most strongly with your own personal expectations and experience, In browserify the process implementation is handled by the applied through brfs would become something like: This is handy because you can reuse the exact same code in node and the browser, There is another form of doing exports specifically for exporting items onto an Browserify is a tool that simplifies the app bundling mechanism by absorbing all the included NPM packages into an app after the code compilation. node_modules/foo or node_modules/app/foo component directory because For every require() call with a string in it, browserify resolves those module reason not to.
