On our 3 main application repos still have some obsolete dependencies (mostly gulp related), that delay the build. It also has some dependencies that are only need locally.

Tasks

• Clean up obsolete gulp dependencies. Make sure all gulp tasks are covered by webpack (eg. svg icons sprite generation).
• Investigate if splitting up dependencies to production and development makes sense (eg. master-theme has a backstop dependency).
• Add a --production flag to planet4-builder on npm ci.
