webpack-bundle-analyzer VS rollup-plugin-visualizer

I used to use webpack-bundle-analyzer but we have switched the builder to browser-esbuild now.

First start by running a webpack bundle analysis to see what exactly is bundled. You might be surprised about things being included that you didn't expect which can help with where to look.

Firstly I recommend taking a look at the structure of the webpack output with something like webpack-bundle-analyzer for any obvious over bundling issues.

See: https://github.com/webpack-contrib/webpack-bundle-analyzer

Webpack Bundle Analyzer

npm run analyse - analyse bundle with webpack-bundle-analyzer

This was my question as well. The article does answer the question, but off the bat I'd assumed the author was talking about output/dist. The web treemap cli is a great tip. If you are using webpack, webpack-bundle-analyzer is a helpful tool for quickly finding bloated packages. It's definitely helped me cut down my build times: https://github.com/webpack-contrib/webpack-bundle-analyzer

Here are a few tipps where you could save some time: 1)check angular.json (configurations -> "your ci config") - look for buildOptimizer / optimization 2)If you run npm ci during your pipeline it might make sense to create the node modules folder beforehand, it seems to save time (https://github.com/npm/cli/issues/2011) 3)Use ng build --stats-json to analyze your build 4)Use https://github.com/webpack-contrib/webpack-bundle-analyzer (also works together with 3. ) 5)Check your package.json for unused dependencies 6)Check your imports, import only what is needed Hope this helps

- `npm run start` - Start the app - `npm run lint` - Lint the project - `npm run test` - Run unit tests - `npm run build` - Build the project - `npm run build:prod` - Build the project in production mode - `npm run build:prod:stats` - Build the project in product mode with stats - `npm run analyse` - Analyse bundle with [webpack-bundle-analyzer](https://github.com/webpack-contrib/webpack-bundle-analyzer) - `npm run compodoc` - Generate [compodoc](https://github.com/compodoc/compodoc) documentation - `npm run version` - Generate changelog - `npm run prettier` - Format the whole project - `npm run audit` - Audit this application using Sonatype OSS Index

I think https://github.com/btd/rollup-plugin-visualizer can help with checking which packages are the largest.

In our "old" build system - I configured webpack-bundle-analyze to inspect bundle chunks and understand what it made of. I added rollup-bundle-visualyzer instead (although there is an issue that the reported size is not correct).
