An implementation of esmac for Webpack to control access between modules. See that project for more details.

The plugin has a familiar Webpack interface for filtering the files it runs against, similar to what you would do with a loader. rules is the only required argument, which is the set of rules to provide to esmac.

// file: webpack.config.js
const ESMACPlugin = require('webpack-esmac-plugin')

module.exports = {
  plugins: [
    new ESMACPlugin({
      rules: [ ... ]
    })
  ]
}

The plugin can generate 2 types of errors that are added to the compilation's list of errors after the modules have been built:

• AccessViolationError when no rule was found to cover the dependency
• SpecifierMismatchError when a rule was found but the specifier check failed

You can choose to format the errors into something meaningful to your users by implementing the formatter function, described in Options.

See ./types.d.ts for the available options.
