Hi,

I have a few feedback on your PR:

1/ Thank you

2/ I see that you made multiple independent changes. To ease the review of those changes, could you isolate them in separate PR? Also, you pushed the package-lock.json Although that is a good practice in general, please don't do it in this PR

Also, you have not pushed any unit test.

Maybe someone familiar with this plugin will want to review your PR "as is"? @hexojs/core ?

[BusinessDuck]

Already use in production that during past six months. Have no issues yet. Too many changes, and too many time is gone sorry can't make a separate pr's. Would be great if someone can review from hexo core team. About units, sure i can cover new features and remove lock json as well.

[bhaskarmelkani]

I will do a review ASAP.

Hey,

Can you remove package-lock.json and add some unit tests, it will make PR easy to read and understand.

I highly appreciate your contribution.

[BusinessDuck]

Added package-lock fix. And i tried to add some units, but i got strange errors in sandbox "ReferenceError: hexo is not defined" when process(ctx) is called (check my todos in css tests)

Hey @BusinessDuck,

I replaced hexo-asset-pipeline with BusinessDuck:master in my setup(that was working fine before) and got following error.

TypeError: Cannot read property 'length' of undefined

To me changes in your PR looks, like breaking changes (which might also have some bugs or miss some corner cases). This will break working setups for users.

Since the change suggested by you is mostly code refactoring, sorry I am afraid that I would not be able to merge these changes.

I hope you understand this. Thanks for your time. If you can provide some small PRs then we can incrementally incorporate them in the plugin.

Thanks :)

no problem, i'll try to make separate pr's later. Whats about my question regarding with hexo sandbox?
