webpack-chunk-renamer-plugin/WebpackChunkRenamerPlugin.js

Adds the template option [lc-name] and allows for chunk renaming

/**
 * Simple Webpack plugin that renames chunks.
 *
 * Adds the template option [lc-name] that will
 * substitute in a lower-case version of a name.
 *
 * This allows exporting a module like Console, while leaving the name of
 * the generate .js file as console.js.
 *
 * Also can allow some chunks to have a different naming
 * convention than others. For example, you can turn off
 * [chunkhash] on vendor.js if required.
