shimming modules
In some cases webpack cannot parse some file, because it has a unsupported module format or isn't even in a module format. Therefore you have many options to convert the file into a module.
The file has dependencies that are not required.
This loader allows put some modules or arbitrary javascript onto a local variable of the file.
Examples:
require("imports?$=jquery!./file.js")
require("imports?xConfig=>{value:123}!./file.js")
Note: you can also configure the loaders in your configuration.
plugin ProvidePlugin
This plugin makes a module available as variable in every module. The module is required only if you use the variable.
Example: Make $
and jQuery
available in every module without writing require("jquery")
.
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
})
The file doesn't export its value.
This loader exports variables from inside the file.
Examples:
var XModule = require("exports?XModule!./file.js")
var XModule = require("exports?Parser=XParser&Minimizer!./file.js"); XModule.Parser; XModule.Minimizer
require("imports?XModule=>undefined!exports?XModule!./file.js")
(import to not leak to the global context)
There are cases where you want a module to export itself to the global context.
Don't do this if you don't really need this
This loader expose the exports to a module to the global context.
Example:
require("expose?XModule!./file.js")
