Webpack Clear Require Cache Plugin
A plugin to delete modules from the require.cache. This is especially useful when working on shared modules inside another webpack project.
Why use this?
In larger projects it makes sense to develop parts of your application inside a separate module that has it's own build and release cycle. Npm provides the functionality to link your local module into the node_modules folder via npm link. Having all the fancy webpack hot-reloading stuff set-up, you might notice that changing your linked module triggers a reload on the webpack build but the module doesn't respect the changes. This happens because your module inside the node_modules folder will be loaded from the require.cache.
Usage
npm install --save-dev webpack-clear-require-cache-pluginconst clearRequireCachePlugin = require('./clearRequireCachePlugin');
module.exports = {
plugins: [
clearRequireCachePlugin([
/my-module/,
]),
],
}The plugin accepts an array of regex's that will be tested on each compiler.hooks.afterEmit. It will test for each module inside require.cache and delete the module if the test returns true.
Next.js Example
The plugin is also compatible with next-js. When you have a linked module inside node_modules within a next-js project webpack will recognize the changes and trigger a reload but from now on client and server are out of sync, because the client will reload the changed module and the server will require from require.cache.
In order to achieve that the server reloades the updated module the next.config.js has to look somethign like this:
const clearRequireCachePlugin = require('./clearRequireCachePlugin');
exports.webpack = config =>
Object.assign(config, {
plugins: [
...config.plugins,
clearRequireCachePlugin([
/\.next\/server\/static\/development\/pages/,
/\.next\/server\/ssr-module-cache.js/,
/my-module/, // replace this with your own module name
]),
],
});
