Release v0.21.0 · insin/nwb

Breaking Changes

Validation of the configuration object provided by nwb.config.js files has been expanded, so previously valid config files may now be invalid [#136]
- Unexpected properties in top-level configuration or in babel, karma, npm and webpack configuration (i.e. anything that's not documented in the Configuration docs) are now treated as errors [#193]
- Basic type checking is now performed for all documented configuration properties.
- After upgrading, run nwb check-config to check your configuration file.
Updated to UglifyJSPlugin 1.x, which supports ES2015 syntax and adds options to enable filesystem caching and use multiple processes to improve build speed, which nwb enables by default [#412]
- Review any custom webpack.uglify config you have against the new version's options documentation - options for UglifyJS itself must now be passed as an uglifyOptions object and some of UglifyJS' default options have changed.
Node.js 4.8.0 is now the minimum required version, based on the engines config of nwb's dependencies.

Deprecated the webpack.compat.sinon flag for Sinon 1.x compatibility settings, as subsequent major versions since July 2017 support Webpack out of the box.

Fixed testing React component/library and web module projects when using export extensions - the Babel stage preset wasn't being defaulted to preset-stage-1, which includes the export extensions plugin [#364]

Added an --open flag to open the app in your default browser or in a named browser (e.g. --open="Google Chrome") after starting a Webpack dev server [#334]
You can now provide a babel.config() function which will be given the generated Babel config to do whatever it wants with.
You can now provide a karma.config() function which will be given the generated Karma config to do whatever it wants with [#408]

Added missing docs for webpack.copy config
Added more headings to the Commands docs to make them easier to browse, and to make feature flags such as --copy-files for component builds more visible [#407]
