FR: Load drivers on demand

[micalevisk]

Is your feature request related to a problem? Please describe.

I want to use the fs driver and another cloud driver. I might not need S3 thus I won't need the aws-sdk dependency as well

nest-storage/package.json

Lines 42 to 47 in add9803

	"dependencies": {
	"aws-sdk": "^2.1058.0",
	"file-type": "^17.1.1",
	"fs-extra": "^10.0.0",
	"rxjs": "^7.5.2"
	},

That dep is quite huge. Having that installed doesn't make much sense in my use case

Describe the solution you'd like

Moving hard dependencies that are driver-specific (like fs-extra and aws-sdk) to optional peer dependencies list

Describe alternatives you've considered

I can use overrides from NPM v8+ or resolutions from Yarn to override those deps to some "noop" one like this one. But this sounds a bit hacky and not reliable to me as those drivers are not lazily loaded.

With this approach, using Yarn, my node_modules size becomes 5x smaller.

Additional context

Having such feature will problably require a major release because now users will need to install those deps beforehand.

At same time, this feature will we could to make the package size smaller regardless of how many drivers are supported.

Hello @micalevisk, I agree with your feedback and the drivers should be made available on demand. Due to office work, I have not been able to focus on this much lately. If you would like to contribute to this package, and raise a PR. Otherwise I will pick this up on coming weekends and do it!

Cheers! 💯

can we use this loadPackage helper approach from NestJS

https://github.com/nestjs/nest/blob/89124ad6d33cbeb55d1f11d6dd69f9e7a95b0f47/packages/common/utils/load-package.util.ts

or do you have another ideia?

I've been pretty busy too but I would like to use nest-storage with GCS thus this feat will be good for me

Sounds like a good solution to me. I will pick it up, you make sure that you don't miss the deadlines :p

Happy Coding! Cheers 💯
