Super super super slow to create Zip files

I have 20+ small functions.

esbuild: {
  packager: 'npm',
  bundle: true,
  minify: false,
  sourcemap: false,
  treeShaking: true,
  nativeZip: true, // 👈 this helps a little but still very slow - in fact without it it mostly fails but with no meaningful error
  concurrency: 10, // 👈 makes no difference
  external: ['migrate-mongo', 'pdfkit', 'pdf-lib', 'jsonwebtoken'],
}

Running on a Mac:

Any ideas?

I’ve also noticed that the generated Zip files are all the same size - this seems weird but it looks like it’s putting everything in the Zip. Am I missing something here?

Good find! That might be related to how we find the entry points since we have to grab the function by splitting

eg. function1.handler means we need to grab the function1 file. So I think we may need to adjust how we find that to allow for the ./ operator.

@samchungy I’ve found the issue. I haven’t drilled in to the exact reason, but understand why.

My handler paths are defined with ./ at the start - this caused all the files to be bundled. Removing that solves the issue and only the required file is bundled in the Zip.
