    Boot

    Boot

    Build tooling for Clojure

    Boot is a Clojure build framework and ad-hoc Clojure script evaluator. Boot provides a runtime environment that includes all of the tools needed to build Clojure projects from scripts written in Clojure that run in the context of the project. Build processes for applications always end up being complex things. A simple web application, for instance, may require many integrations–asset pipelines, deployment to different environments, the compilation of multiple artifacts with different compilers, packaging, etc. The more complex the build process becomes, the more flexible the build tool needs to be. Static build specifications become less and less useful as the project moves toward completion. Being Lispers we know what to do: Lambda is the ultimate declarative. Instead of building the project based on a global configuration map, boot provides a runtime environment in which a build script written in Clojure can be evaluated. It is this script.

    Cyclops

    Cyclops

    An advanced platform for writing functional applications in Java 8

    Fast purely functional datastructures (Vector, Seq / List, LazySeq / LazyList, NonEmptyList, HashSet, TreeSet, TrieSet, HashMap, LinkedMap, MultiMap, TreeMap, BankersQueue, LazyString, Discrete Interval Encoded Tree, Zipper, Range, Tree, DifferenceList, HList, Dependent Map). Structural Pattern Matching API (deconstruct algebraic product and sum types). Improved type safety via the removal of unsafe APIs -- E.g. Unlike Optional, Option has no get method (which could throw a null pointer) -- New data structures do not support operations that would throw exceptions (you can't call head on an empty list for example). Eager and Lazy alternatives for most datastructures (Option is eager, Maybe is lazy + reactive). Improved naming of types (Function1-8 rather than Fn1-8, Either not Xor). Group id is changed to com.oath.cyclops. Versioning between cyclops-react and cyclops is merged on cyclops versioning scheme (version 10 = Cyclops X).

    Dagger

    Dagger

    Fast dependency injector for Android and Java

    Dagger is a fully static, compile-time dependency injection framework for Java, Kotlin, and Android. It is an adaptation of an earlier version created by Square and now maintained by Google. The latest Dagger release is: Dagger 2.33. Dagger aims to address many of the development and performance issues that have plagued reflection-based solutions. Dagger is a replacement for the FactoryFactory classes that implements the dependency injection design pattern without the burden of writing the boilerplate. It allows you to focus on the interesting classes. Declare dependencies, specify how to satisfy them, and ship your app. Dependency injection frameworks have existed for years with a whole variety of APIs for configuring and injecting. So, why reinvent the wheel? Dagger 2 is the first to implement the full stack with generated code. The guiding principle is to generate code that mimics the code that a user might have hand-written to ensure that dependency injection is simple.

    Jib

    Jib

    Containerize your Java application

    Containerize your Java application with Jib! Jib builds optimized Docker and OCI images for your Java applications-- no Docker daemon or deep mastery of Docker best-practices required. Jib builds by separating the traditionally single image layer Java application into multiple layers for more granular incremental builds. This results in only changes to your code being rebuilt, not your entire application. Jib deploys your changes fast and allows you to rebuild your container image exactly the same without triggering unnecessary updates. All this done completely daemonless, reducing your CLI dependencies.

    GraphQL SPQR

    GraphQL SPQR

    Build a GraphQL service in seconds

    GraphQL SPQR (GraphQL Schema Publisher & Query Resolver, pronounced like speaker) is a simple-to-use library for rapid development of GraphQL APIs in Java. GraphQL SPQR aims to make it dead simple to add a GraphQL API to any Java project. It works by dynamically generating a GraphQL schema from Java code. When developing GraphQL-enabled applications it is common to define the schema first and hook up the business logic later. This is known as the schema-first style. While it has its advantages, in strongly and statically typed languages, like Java, it leads to a lot of duplication. Both of these blocks contain the exact same information. Worse yet, changing one requires an immediate change to the other. This makes refactoring risky and cumbersome, and the compiler can not help. On the other hand, if you’re trying to introduce a GraphQL API into an existing project, writing the schema practically means re-describing the entire existing model.

    Litho

    Litho

    A declarative framework for building efficient UIs on Android

    Litho uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, Litho can perform optimisations for your UI under the hood, while keeping your code simple and easy to maintain. Litho can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from the traditional Android View system, Litho can drop the UI thread constraint imposed by Android. Litho uses Yoga for layout and automatically reduces the number of ViewGroups that your UI contains. This, in addition to Litho's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance.

    MVPArms

    MVPArms

    A common architecture for Android applications developing based on MVP

    A common Architecture for Android Applications developing based on MVP, integrates many Open Source Projects (like Dagger2, RxJava, Retrofit, etc.), to make your developing process quicker and easier. This framework combines them and uses them all. Dagger2 is managed and provided to developers. Using this framework to develop your project means that you already have an MVP + Dagger2 + Retrofit + RxJava project. MVPArt is a new MVP architecture, suitable for small and medium-sized projects. It aims to solve the problems of too many traditional MVP classes and interfaces. One-click template generation, development artifact, no regrets! General framework, suitable for all types of projects, supports the development of large projects, compatible with component development, and can be used as a componentized Base library. The original builder mode Module (GlobalConfigModule) can be used to inject custom parameters into any position of the framework using Dagger2.
