    Blurhash

    Blurhash

    Library to show colorful blurry placeholders while your content loads

    A library to show colorful blurry placeholders while your content loads. Does your designer cry every time you load their beautifully designed screen, and it is full of empty boxes because all the images have not loaded yet? Does your database engineer cry when you want to solve this by trying to cram little thumbnail images into your data to show as placeholders? Replace boring grey boxes with beautiful blurhash states and the designers will be happy. Blurhash strings are short enough to be added as a field in a JSON object and to be stored in a database. The implementations are small and easy to port to new languages, and the end result is a smooth and interesting experience for your users. In short, BlurHash takes an image and gives you a short string (only 20-30 characters!) that represents the placeholder for this image. You do this on the backend of your service and store the string along with the image.

    Component Jetpack Kotlin MVVM

    Component Jetpack Kotlin MVVM

    Componentized Jetpack Kotlin MVVM project practice

    Componentized Jetpack Kotlin MVVM project practice, involving Jetpack-related components, Kotlin-related technologies, coroutine Retrofit, Paging3 Room, etc. When running the main App, the sub-module belongs to the library, and when running independently, the sub-module belongs to the application. Then we only need to add a flag in gradle.properties in the root directory to distinguish the status of the module, such as singleModule = false. This flag can be used to indicate whether the current Module is an independent module. true means it is an independent module. Run alone, false means it is a library.
