v0.22.0

Breaking Changes

• Node.js 4 is no longer supported; Node.js 6.11.5 is now the minimum required version, as per Webpack 4 [#400]
• Updated to Webpack 4 - if you were customising your build with nwb.config.js, some of the nwb config you depended on may have changed, and the options Webpack accepts may have changed [#409]
  • Webpack's new mode option is now set to activate Webpack 4's new defaults, which removes the need for a bunch of manual configuration nwb was doing:
    • ModuleConcatenationPlugin is now automatically enabled in production mode instead of being explicitly configured, so nwb's webpack.hoisting config has been removed.
    • NamedModulesPlugin is now automatically used in development mode instead of being explicitly configured.
    • Development UMD builds for modules now use production mode with minimization disabled, as the new development mode defaults are unsuitable for code which will be published to npm.
  • Webpack's optimization options are now used for certain pieces of configuration:
    • optimization.noEmitOnErrors is used instead of NoEmitOnErrorsPlugin to prevent emission of assets when using Hot Module Replacement.
    • UglifyJS is now configured via optimization.minimize/optimization.minimizer instead of just adding UglifyJsPlugin directly to plugins.
    • CommonsChunkPlugin has been removed in Webpack 4 - optimization.runtimeChunk is now configured to create a runtime chunk (which replaces the old manifest chunk) and optimization.splitChunks is configured to create a vendor bundle.
  • Replaced used of ExtractTextPlugin with MiniCssExtractPlugin:
    • Separate CSS files are now created and loaded on-demand for code splits.
    • Replaced webpack.extractText config with webpack.extractCSS config - this is not backwards-compatible, as plugin options differ.
  • Webpack's default performance option size warnings have been disabled (for now).
• Updated Inferno config for Inferno v4 - see the Inferno v4 migration guide for breaking changes [#429]
  • nwb new inferno-app now asks if you want to install inferno-compat as it's no longer a single dependency, defaulting to not installing it.
• nwb new preact-app now asks if you want to install preact-compat, defaulting to not installing it.
• Updated to Mocha 5, which dropped support for IE9 and IE10 and fixed some false positives.
• Removed support for deprecated webpack.compat.enzyme, webpack.compat.sinon and webpack.style = 'old' config.

Known Issues

• Inferno is currently publishing .mjs files to npm, which is breaking inferno-* packages with Webpack 4, so e.g. inferno-compat won't work if you want to reuse React components.

Added

• Added an -f/--force flag to nwb new to accept defaults and skip questions.

Changed

• The dev server's fallback index.html serving can now be configured with dot arguments - e.g. pass --fallback.disableDotRule if you need to use dots in your path when using the HTML5 History API.
• --no-polyfill can now be used to disable default polyfills for app projects as well as quick commands.
