// Useful to keep lambdas sizes low when vercel/nft isn't able to drop unneeded deps for you.
// This is particularly useful to remove musl binaries when deploying on vercel for example.
// (ie esbuild-musl, swc-musl...). This also also help to keep docker images smaller
//
// Note that yarn 3+/4 is less impacted thanks to supportedArchitectures.
// See https://yarnpkg.com/configuration/yarnrc#supportedArchitectures and
// config example in https://github.com/belgattitude/nextjs-monorepo-example/pull/3582
// NPM/PNPM might adopt https://github.com/npm/rfcs/pull/519 in the future.
//
// Caution: use it with care because you'll have to maintain this over time.
//
// How to debug in vercel: set NEXT_DEBUG_FUNCTION_SIZE=1 in vercel env, then
// check the last lines of vercel build.
//
