How to Effectively Manage jQuery Plugin Dependencies with Webpack?

How to Manage jQuery Plugin Dependencies in Webpack
When using webpack, it's common to organize application code and libraries into separate bundles. For instance, one might create a "bundle.js" for all custom code and a "vendors.js" for libraries such as jQuery and React. However, challenges arise when incorporating plugins that depend on jQuery and are desired within "vendors.js."
ProvidePlugin: Global Variable Injection
One approach is to utilize the ProvidePlugin, which injects implicit globals when encountering specific identifiers, such as "$" or "jQuery." By configuring webpack, one can instruct it to prepend "var $" when encountering "$" globally.
Example:
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
})
]
imports-loader: This Binding Configuration
The imports-loader allows manual variable injection. Some legacy modules assume the presence of "this" as the window object, which can conflict with CommonJS contexts where "this" equates to "module.exports." The imports-loader can override this behavior and bind "this" to the window object.
Example:
module: {
loaders: [
{
test: /[\/\]node_modules[\/\]some-module[\/\]index\.js$/,
loader: "imports-loader?this=>window"
}
]
}
imports-loader: AMD Disabling
Certain modules support multiple module styles, including AMD and CommonJS. However, they may prioritize define and employ unconventional exporting methods. This can be circumvented by forcing CommonJS by setting "define = false" with the imports-loader.
Example:
module: {
loaders: [
{
test: /[\/\]node_modules[\/\]some-module[\/\]index\.js$/,
loader: "imports-loader?define=>false"
}
]
}
script-loader: Global Script Importation
If global variables are not a concern and simply executing legacy scripts is the objective, the script-loader can be used. It runs modules within a global context, akin to using a

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
