    LWJGL

    LWJGL

    Java library that enables cross-platform access to popular native APIs

    LWJGL is a Java library that enables cross-platform access to popular native APIs useful in the development of graphics (OpenGL, Vulkan), audio (OpenAL) and parallel computing (OpenCL) applications. This access is direct and high-performance, yet also wrapped in a type-safe and user-friendly layer, appropriate for the Java ecosystem. LWJGL is an enabling technology and provides low-level access. It is not a framework and does not provide higher-level utilities than what the native libraries...

    ZXingLite

    ZXingLite

    Simplified version of ZXing, optimized to scan codes to generate QR

    ...(Applicable to most scenarios, and you don’t need to care about the code scanning related logic, you need to override the getLayoutId method when customizing the layout) Implementation examples: CustomCaptureActivity and QRCodeActivity. Instantiate a CameraScan in the Activity or Fragment of your project. (Applicable to use when you want to write interactive logic on the code scanning interface, and cannot directly or indirectly inherit CaptureActivity or CaptureFragment due to project architecture or other reasons)

    J2CL

    J2CL

    Java to Closure JavaScript transpiler

    J2CL is a lightweight transpiler developed by Google that converts Java source code into highly optimized JavaScript designed to work seamlessly with the Closure Compiler. It allows developers to write applications in Java while targeting web environments, enabling strong type safety and code reuse across platforms. Unlike monolithic frameworks, J2CL focuses purely on transpilation, leaving optimization, bundling, and runtime concerns to the broader toolchain, which provides flexibility in modern development workflows. The generated JavaScript is fully type-safe and can be aggressively optimized by the Closure Compiler to reduce code size and improve performance. ...

    RxJava

    RxJava

    Reactive Extensions for the JVM

    RxJava is a lightweight Java VM implementation of ReactiveX (Reactive Extensions). This is a library for the composition of asynchronous and event-based programs through observable sequences. It helps you write cleaner and simpler code by providing methods for solving problems quickly, and is easy to maintain and understand. RxJava works by extending the observer pattern in order to support sequences of data/events. It also allows you to compose sequences together declaratively through added operators, all while abstracting away concerns like low-level threading, thread-safety, concurrent data structures and synchronization. ...

    Caffeine

    Caffeine

    A high performance caching library for Java

    Caffeine is a high performance Java caching library providing a near optimal hit rate. A Cache is similar to ConcurrentMap, but not quite the same. The most fundamental difference is that a ConcurrentMap persists all elements that are added to it until they are explicitly removed. A Cache on the other hand is generally configured to evict entries automatically, in order to constrain its memory footprint. In some cases a LoadingCache or AsyncLoadingCache can be useful even if it doesn't evict...

    A small redis java client

    ...The features supported are sorting, connection handling, commands operating on any kind of values, commands operating on string values, commands operating on hashes, commands operating on lists, commands operating on sets, commands operating on sorted sets, commands operating on streams, transactions, pipelining, publish/subscribe, persistence control commands, remote server control commands, connection pooling, sharding (MD5, MurmurHash), key-tags for sharding, sharding with pipelining, scripting with pipelining, and Redis Cluster. Redis is primarily built for master/slave distribution. This means that write requests have to be explicitly addressed to the master (a redis server), which replicates changes to slaves (which are also redis servers).

    MMKV for Android

    MMKV for Android

    An efficient, small mobile key-value storage framework

    A configuration as code language with rich validation and tooling

    pkl is a purpose-built configuration-as-code language developed by Apple that combines declarative structure, validation, and tooling to improve over traditional configuration formats like JSON, YAML, or Plists. Its goal is to let you write configuration logic (modules, imports, conditions, defaults) while still producing static outputs suitable for tools that expect JSON, YAML, or other formats. Configurations in Pkl are type-safe and support validation constraints (e.g. bounds, relations) so many errors can be caught before deployment. The language is embeddable, meaning it can run inside applications (Java, Swift, Go, etc.) to load configuration dynamically with the same safety guarantees. ...

While Spring Boot speeds up the development process, developers still require extensive knowledge, must ensure adherence to best practices, and often write repetitive code for each project. First, the name Sakura Boot is named to reflect its foundation on Spring Boot, while "Sakura" symbolizing the brief cherry blossoms season in Japan, this highlights the framework’s focus on rapid and efficient backend development.
