Buddy\n====\n\nBundle Buddy is a tool to help you find source code duplication across your javascript chunks/splits. This enables you to fine tune code splitting parameters to reduce bundle invalidation rates as well as improve repeat page load performance \\o/.\n\n

Example Bundle Buddy UI

\n\n\nBundle Buddy operates on any source maps, but you *must* include the source content. It will work for any CSS/JS/TEMPLATES etc. that is mapped.\n\nIn webpack this means setting devtool to `source-map`\nhttps://webpack.js.org/guides/development/#source-maps\n\n### webpack users\nIf you are using webpack, you can also try the [bundle-buddy-webpack-plugin](https://github.com/TheLarkInn/bundle-buddy-webpack-plugin). This helps ensure you configure your sourcemaps correctly, and lets you run bundle-buddy directly from a webpack build. You might want to use this if you don't want to use bundle buddy standalone!\n\n-----\n\n## How to use?\n\nBuild your app, then run directly via npx\n\n```bash\nnpx bundle-buddy my-app/public/*.map\n```\n\nOr you can install into your project and run with npm\n\n```bash\nnpm install -g bundle-buddy\n\nbundle-buddy my-app/public/*.map\n```\n\n### Bundle Buddy UI interactions.\n\n\n\nWhen you select a bundle on the left panel, you can then see the bundle breakdown, which shows you the most duplicated source lines across bundles that the currently selected bundle contains.\n\nAfter clicking on a bundle chunk we will then show you the lines of the source file that are repeated as well as what other bundles contain said source lines.\n\n\n### Acting on the results.\n\nThe ideal workflow flow using Bundle Buddy is to first identify what code is most duplicated across the project's bundles, then to utilize a common code bundling techique (https://webpack.js.org/plugins/commons-chunk-plugin/), then to rebuild your site, and then *finally* to measure again to see your impact.\n\n### How does this work?\n\nBundle Buddy builds up a mapping across every source map of every file and each line in each file that is used. This enables Bundle Buddy to detect common source lines between different project chunks.\n\n----\n\n\n### Contributing\n\nWorking on the front end is simple\n\n```bash\ncd viz\nyarn install\nyarn start\n```\n\nWorking on the CLI component is also straight forward, you just need to build the front end once first.\n\n```bash\npushd viz\nyarn install\nyarn build\npopd\nyarn install\nyarn start --demo\n```\n","_attachments":{},"license":"MIT"}
