webpack-sandboxed  

Webpack in a sandbox. Run webpack on a in-memory file system, reading from a source string and outputting results as strings again. This is useful when using webpack for compiling bundles on the fly, e.g. on a web server.

---

Usage

import webpackSandboxed from 'webpack-sandboxed';

const options = {
  config: { /* webpack configuration */ },
  packages: [ /* names of modules to load in the sandbox */ ],
  includes: [ /* local file paths to load in the sandbox */ ],
  baseDir: 'base directory to resolve modules'
};

const sandbox = await webpackSandboxed(options);
const [bundle, stats] = sandbox.run("exports = {foo: 'bar'};");
