Hey everyone,

I just noticed that my all lambdas had their zip size increase at least by 10x than what was before on v3. Has anyone ever experience this issue after switching to V4? On v3, I had serverless-esbuild and everything was good without any special configurations. V4 has serverless-esbuild built in and i was expecting it to work the same, but it obviosly is not.

Tried using same config here, but no change in lambda zip size.

Any recommendations for change?

My prev config. Added no additional config for serverless-esbuild

  package: {
    individually: true, // bundle size affects cold starts: package individually
    patterns: ['!package-lock.json'],
    exclude: ['**/node_modules/**'],
  },

Tried to add default config with v4 to see if there any changes but no changes in lambda size.

  build: {
    esbuild: {
      bundle: true,
      minify: true,
      external: ['@aws-sdk/client-s3'],
      exclude: ['@aws-sdk/*'],
      packages: 'external',
      buildConcurrency: 3,
      sourcemap: {
        type: 'linked',
        setNodeOptions: true,
      },
    },
  },
