Module bundling
Bundling your Screeps codebase using module bundlers like Webpack or Rollup allows you to improve your Screeps AI development workflow.
For instance, it allows you to easily include third-party libraries, like screeps-profiler and Traveler. Instead of manually copy-pasting these libraries into your code, you can simply install it as an npm module:
npm install screeps-profiler
Then you can import these libraries just like you would any other npm module. When you run the module bundler, it will bundle up all your files and third-party modules into one single JS file.
Some module bundlers even support performing further optimisations like eliminating unused module functions from your final bundled code (aka. tree-shaking), reducing the size of your final bundled JS even further.
Rollup
From version 3.0 onwards, the starter kit uses Rollup as its main module bundler. Some useful features of Rollup include:
- Bundled modules are entirely flat (no weird boilerplate code emitted like in Webpack)
- Advanced tree-shaking (eliminates unused modules from the final bundle)
- Simpler configuration (compared to Webpack)
If you're still comfortable with using Webpack, the old version of the starter kit is available here (TODO: legacy branch link), but moving forward, no new features will be added to the Webpack version.
