Provide possibility to use only specific operators

Hello,

You are working on the awesome project 😃 And I’d like to use it inside my library. The only issue is bundle size.

So, I want to request possibility to use only specific query operators. For example, I want to use only query operators and simple operators. I don’t need projection, agregation, etc.

Do you think you can extract that in some core bundle and deliver it separetely (at least its ES6 version)?

Hey @stalniy, thanks for creating this issue.

I agree with you that this should perhaps be split across different modules.

That has been my plan from the start which gave birth to mingo-geo and mingo-stream packages even though they haven’t seem much development since.

I think why I didn’t pursue this fully was that the operators weren’t that many at the time and the convenience of hosting everything in one package.

I will explore how best this can be split up by functionality into separate packages and while keeping them amalgamated in this one by taking dependencies (e.g. mingo-core, mingo-aggregate etc). It could be more challenging than I anticipate given I that I have implemented some operators by depending on others which might end up being separated.

You are welcome to share any ideas about this.

Thanks.

The coming 3.0.0 loads only query and projection operators by default. All other operators must be explicitly required and registered. This effectively supports tree shaking to reduce bundle size.
