v2.1.0-beta.23

Breaking Changes:

removed postLoaders and preLoaders

rules enforce: "left" and enforce: "right" can be used instead.

rules should be used instead of loaders, but the old one still work.

Same syntax + additional options. Allows to configure the parser too. Allows matching by issuer.

configuration is validated against a schema

moved parser instancation into NormalModuleFactory

compiler.parser must no longer be used. Use this instead:

compiler.plugin("compilation", function(compilation, params) {
  params.normalModuleFactory.plugin("parser", function(parser, parserOptions) {
    parser.plugin(/* ... */);
  });
});

Features:

  • manifest can be a path to a manifest, which is resolve at compile time.
• Rules
