copy-webpack-plugin

What is copy-webpack-plugin?

The copy-webpack-plugin is a webpack plugin that allows you to copy files and directories from one location to another within your build process. It is commonly used to copy static assets such as images, fonts, and HTML files to the output directory defined in your webpack configuration.

What are copy-webpack-plugin's main functionalities?

Copying individual files or entire directories

This feature allows you to copy individual files or entire directories from a specified source to a destination within your output directory. The 'from' field specifies the relative or absolute path to the source file or directory, and the 'to' field specifies the relative path to the destination within the output directory.

new CopyPlugin({ patterns: [{ from: 'source', to: 'dest' }] })

Ignoring files

This feature allows you to exclude specific files or patterns from being copied. In the provided code sample, all JavaScript files are ignored and will not be copied to the destination.

new CopyPlugin({ patterns: [{ from: 'source', to: 'dest', globOptions: { ignore: ['**/*.js'] } }] })

Adding context to file paths

This feature allows you to specify a context for the file paths. The 'context' option sets a base path for the 'from' property. In the code sample, the actual path that will be copied is 'app/source'.

new CopyPlugin({ patterns: [{ from: 'source', to: 'dest', context: 'app' }] })

Transforming file content

This feature allows you to modify the content of files before they are copied. The 'transform' function receives the content of the file and its path, and it should return the new content. This can be used to minify files, add banners, or perform other transformations.

new CopyPlugin({ patterns: [{ from: 'source', to: 'dest', transform: (content, path) => { return modifyContent(content); } }] })
