How does the require function work in Webpack?
An implementation of the require function is sent as a parameter to this function. The function body can use this to further require () modules it needs for execution. errorCallback: A function that is executed when webpack fails to load the dependencies. chunkName: A name given to the chunk created by this particular require.ensure ().

Q. Which is the best way to install Webpack?
Alternatively, if you are using npm v5.2.0 or greater, you can run ‘npx webpack’ to do it. The following NPM installation will make webpack available globally: Note that this is not a recommended practice. Installing globally locks you down to a specific version of webpack and could fail in projects that use a different version.
Q. Are there any CommonJS methods supported by Webpack?
The following CommonJS methods are supported by webpack: Synchronously retrieve the exports from another module. The compiler will ensure that the dependency is available in the output bundle. It’s possible to enable magic comments for require as well, see module.parser.javascript.commonjsMagicComments for more.
Q. Is there a way to not bundle a module in Webpack?
Any module that matches will not be bundled. Note that webpackInclude and webpackExclude options do not interfere with the prefix. eg: ./locale. webpackExports: tells webpack to only bundle the specified exports of a dynamically import () ed module. It can decrease the output size of a chunk.
Q. When to use factoryMethod and exports in Webpack?
If dependencies are not provided, factoryMethod is called with require, exports and module (for compatibility!). If this function returns a value, this value is exported by the module. The compiler ensures that each dependency is available. Note that webpack ignores the name argument.
Q. Which is the issuer of a Webpack module?
The issuer: An absolute path to the file of the module which requested the resource. It’s the location of the import. Example: When we import ‘./style.css’ within app.js, the resource is /path/to/style.css and the issuer is /path/to/app.js.
Q. Why does Webpack not find interfaces in typescript?
Basically the typescript compiler emits no code for interfaces, so webpack can not find them in the compiled module; except when a module consists of only interfaces. In that case the module will end up completely empty and then webpack will not investigate the exports. You should probably create a new issue for your problem.
Q. How to fix [ object module ] in image SRC of Webpack output?
The solution is to set the esModules object to false in the file-loader rule like so When i using file-loader and html-loader in webpack. The src attr of image gonna be like ‘ [object Module]’
Q. What’s the best way to import in Webpack?
The first and recommended approach is to use the import() syntax that conforms to the ECMAScript proposal for dynamic imports. The legacy, webpack-specific approach is to use require.ensure. Let’s try using the first of these two approaches… import() calls use promises internally.
Q. Can you have more than one module in Webpack?
While webpack supports multiple module syntaxes, we recommend following a single syntax for consistency and to avoid odd behaviors/bugs. Actually webpack would enforce the recommendation for .mjs files, .cjs files or .js files when their nearest parent package.json file contains a “type” field with a value of either “module” or “commonjs”.
Q. What’s the best way to split code in Webpack?
Dynamic Imports Two similar techniques are supported by webpack when it comes to dynamic code splitting. The first and recommended approach is to use the import () syntax that conforms to the ECMAScript proposal for dynamic imports. The legacy, webpack-specific approach is to use require.ensure.
