Our original goal for this hackathon this year was to speed up the web builds. But, as you will see, this year is special, and we have not tackled one, but two subjects in the same hackathon! Speed up web builds using esbuild Before the hackathon, our web build system was basically composed of webpack , with ts-loader to transpile TypeScript into JavaScript, fork-ts-checker-webpack-plugin to enable TypeScript type checking, and eslint for additional static analysis.
