Option to skip packaging externals

[samrith-s]

Hey,

I have these options in my SLS config:

package:
    exclude:
        - 'cache-manager'
        - 'class-transformer'
        - 'class-validator'
        - '@nestjs/microservices'
        - '@nestjs/websockets'
    individually: true
custom:
    esbuild:
        bundle: true
        minify: true
        keepNames: true
        sourcemap: true
        external:
            - 'cache-manager'
            - 'class-transformer'
            - 'class-validator'
            - '@nestjs/microservices'
            - '@nestjs/websockets'
        plugins: 'esbuild.plugins.js'

However, once it bundles, it runs this:

Packing external modules: cache-manager, class-transformer, class-validator, @nestjs/microservices, @nestjs/websockets

I want to completely skip it as these packages are opt-in in NestJS. Is there any way to achieve it? I see from the code that this plugin packages externals. Is there any way to completely skip them?

Hello @samrith-s

You can list modules in the external section to not include them in the final artifact.

The package specified in the exclude option is passed to esbuild as external, but it is not included in the function bundle either. The default value for this option is ['aws-sdk'].

Please let me know if that works for you.

Hey @vamche ,

Thanks for your response. Afaik, I am already doing that. All the packages are listed in custom.esbuild.external and package.exclude, yet it packages them.

@samrith-s I was talking about the serverless-esbuild config. Could you please list them in custom.esbuild.external and try?

   custom:
    esbuild:
        bundle: true
        minify: true
        keepNames: true
        sourcemap: true
        external:
            - 'cache-manager'
            - 'class-transformer'
            - 'class-validator'
            - '@nestjs/microservices'
            - '@nestjs/websockets'
        exclude:
            - 'cache-manager'
            - 'class-transformer'
            - 'class-validator'
            - '@nestjs/microservices'
            - '@nestjs/websockets' 
        plugins: 'esbuild.plugins.js'

@samrith-s Did you get a chance to try with custom.esbuild.external?
