Changelog Entry

Description

(Copied from #2583.)

This bug only affect users who "npm install" Web Chat with devDependencies, e.g. playground or any packages that use npm link or lerna to include Web Chat in their build.

When botframework-webchat is installed with devDependencies, it installed React 0.14.9 due to transient dependencies from webpack-visualizer-plugin

botframework-webchat do not include devDependencies of React 16.8.6. This is because of the "Rules of Hooks" to maintain a single instance of React. We do include React 16.8.6 at the root package, so both playground and botframework-webchat-* will share the same instance of React.

Specific Changes

• bundle: Replace webpack-visualizer-plugin plugin with webpack-stats-plugin

• Testing Added
  • No tests are added for playground
