GPU Image VS Kingfisher

Lanczos algorithm is around 200 lines . https://github.com/BradLarson/GPUImage/blob/master/framework/Source/GPUImageLanczosResamplingFilter.m

The 3rd party library I use GRDB SwiftyUserDefaults Kingfisher SwiftDate Popovers

Saving URLs definitely the way to go. Would recommend using a library such as Kingfisher to do the image loading/ caching for you.

I also looked into this github library but wanted to first ask if anyone's had any experience using it.

You can checkout Kingfisher library (it downloads image, and caches it). Usage is fairly simple but I would recomment that you create extension for the UIIMageView, somthing in line like this:

In native iOS, most people use Kingfisher, and i'd love to have something as good as that on our RN app. Perhaps just some pure JS library that you could plug on the existing image component, and that would handle the saving-to-disk and fetching of the image?

Kingfisher - Download and cache images

We are using https://github.com/onevcat/Kingfisher for smooth image loading in collection view. If the image data are not in regular text file, how can we integrate CoreData's blob data with Kingfisher?

Make sure the proper target is selected in the Add to target in the dialog as shown above, then click Add Package button. The package should successfully be added to your project. Now following the same process, this time search for the Kingfisher package using the GitHub URL as the following https://github.com/onevcat/Kingfisher.
