Package Exports

webpack-dev-middleware

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (webpack-dev-middleware) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

webpack-dev-middleware

THIS MIDDLEWARE SHOULD ONLY USED FOR DEVELOPMENT!

DO NOT USE IT IN PRODUCTION!

What is it?

It's a simple wrapper middleware for webpack. It serves the files emitted from webpack over a connect server.

It has a few advantages over bundling it as files:

No files are written to disk, it handle the files in memory
If files changed in watch mode, the middleware no longer serves the old bundle, but delays requests until the compiling has finished. You don't have to wait before refreshing the page after a file modification.
I may add some specifiy optimation in future releases.

Usage

var webpackMiddleware = require("webpack-dev-middleware");
app.use(webpackMiddleware(...));

Use the webpackMiddleware function like the webpack function, but without callback. Example usage:

app.use(webpackMiddleware(__dirname, "./lib/file", {
    watch: true,
    debug: true,
    publicPrefix: "http://localhost:8080/assets/",
    output: "bundle.js",
    outputPostfix: ".bundle.js",
    // ... more webpack config options
}));

options.watch = true

This is not required, but recommendated to get the best out of the middleware.

options.publicPrefix

The prefix for request that should be handled.

options.output, options.outputPostfix

The filename for the bundle.

options.verbose

Verbose output of the statistics.
