| # script for comparing how the build results have changed. | |
| # useful for checking if the build is still working as expected, especially when you're playing around with babel or webpack config | |
| # How to use: | |
| # 1. Open a baseline branch, and run `npm run build` | |
| # 2. Copy paste all output folders into `build-baseline`: es6 lib types umd | |
| # 3. Run `./scripts/check-build-diff.sh` | |
| # 4. The script will print all differences between current build and baseline build. | |
| # empty output means no differences. | |
| # 'build' folder is excluded because that's typescript output only and is not released. | |
| pushd .. | |
| set -o pipefail | |
| set -o errexit | |
| set -o nounset | |
| echo "Starting build" | |
| # the build will fail if it produces different file names, so no need to check for that | |
| npm run build > /dev/null | |
| echo "Build complete, running diff" | |
| # compares all files except UMD files, and prints differences | |
| find es6 lib types -type f -exec sh -c 'diff --color=always --unified=0 "build-baseline/$1" "$1"' _ {} \; | |
| # the UMD build is one large minified file so let's break it down to shorter lines before comparing | |
| diff --color='always' <(cat build-baseline/umd/Recharts.js | tr ';' '\n') <(cat umd/Recharts.js | tr ';' '\n') | |
| echo "Diff complete" | |
