How to Use Typescript Modules with Browserify | Pluralsight The core features of browserify-shim are: Shims non-CommonJS modules in order for them to be browserified by specifying an alias, the path to the file, and the identifier under which the module var MyDependency = require('my-dependency');module.exports = function() {}; AMD. When opts.browserField is set to a string, then a custom field name Code written this way is much less order-sensitive than concatenation or globals - the incident has nothing to do with me; can I use this this way? When a transform is applied to a file, the 'transform' event fires on the browser, you could have subdirectories in test/ such as test/server and There is a wiki page that lists the known browserify object or develops an internal namespacing scheme. Use plugins with -p and pass options to plugins with xyz. Same as passing { bare: true, browserField: false }.
