bundler-benchmarking

This project was made to benchmark different bundlers under different constraints.

Current bundlers measured:

• esbuild
• parcel
• rollup
• webpack

These benchmarks use a generated application using yarn generate.

Installation

git clone git@github.com:j0sh77/bundler-benchmarking.git
cd bundler-benchmarking
yarn install

Usage

Generating a site

yarn generate -c $CHILDREN -d $DEPTH -s $STYLES

Generates a sample site where a tree of react components is created. Each node of the tree has c children and the tree is of depth d. If s is true, a stylesheet will be generated for each component.
