library0.1.0jsnpmunverified

A wrapper around webpack-dev-middleware that adds a lazy LRU cache for webpack entrypoints. When using webpack configurations with many entrypoints, it avoids building unused modules by only building entrypoints on demand. Supports preloading initial entries, mapping requests to entrypoint names, and lifecycle hooks. Current stable version is v0.1.0, released in 2017. It is in maintenance mode with no recent updates. It is intended for development use with Express/Connect-like servers.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default export
✓ const webpackLRU = require('webpack-lru-middleware');
The package is CommonJS only and does not ship TypeScript types.
default export
✓ import webpackLRU from 'webpack-lru-middleware';
✗ import { webpackLRU } from 'webpack-lru-middleware';
This is a default export; named import will not work.

Sets up webpack-lru-middleware with a webpack config, creating a lazy LRU cache for entrypoints.

const webpack = require('webpack'); const webpackDevMiddleware = require('webpack-dev-middleware'); const webpackLRU = require('webpack-lru-middleware'); const path = require('path'); const lru = webpackLRU({ defaultEntry: { __empty__: path.resolve(__dirname, './empty.js') }, initialEntry: [], mapToEntry: req => path.basename(req.path, '.js'), }); const webpackConfig = { entry: {}, // will be overridden by lru output: { filename: '[name].js', path: '/dist' } }; const compiler = webpack(lru.configure(webpackConfig)); const devMiddleware = webpackDevMiddleware(compiler); app.use(lru.createMiddleware(devMiddleware));
