    Skript

    Skript

    Skript is a Bukkit plugin which allows server admins

    Skript is (surprise, surprise) a scripting plugin for the Bukkit platform. It is easy to use for simple tasks, but you can also create really complex things with it. The syntax of Skript is close to English, but it is still not magic. While you might succeed with experimentation for simple tasks, for anything more complex you will need some guidance. You will find all supported features of the plugin here, along with some useful examples. We don't have tutorials yet, but you can find good ones using whatever search engine you prefer. Skript requires Spigot to work. You heard it right, CraftBukkit does not work. Paper, which is a fork of Spigot, is recommended; it is required for some parts of Skript to be available. Skript supports only the latest patch versions of Minecraft 1.9+. For example, this means that 1.16.5 is supported, but 1.16.4 is not. Testing with all old patch versions is not feasible for us.

    Spring Cloud Config Server

    Spring Cloud Config Server

    External configuration (server and client) for Spring Cloud

    Spring Cloud Config provides server-side and client-side support for externalized configuration in a distributed system. With the Config Server, you have a central place to manage external properties for applications across all environments. The concepts on both client and server map identically to the Spring Environment and PropertySource abstractions, so they fit very well with Spring applications but can be used with any application running in any language. As an application moves through the deployment pipeline from dev to test and into production, you can manage the configuration between those environments and be certain that applications have everything they need to run when they migrate. The default implementation of the server storage backend uses git, so it easily supports labelled versions of configuration environments as well as being accessible to a wide range of tooling for managing the content. It is easy to add alternative implementations.

    lixa

    lixa

    LIXA, LIbre XA, is a free and open source XA transaction manager

    LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.

    RocketMiX

    RocketMiX

    RocketMix API Platform

    Go to project's home page here (in french only) : https://rocketmix.github.io Go to source code and technical documentation here : https://github.com/rocketmix/rocketmix.source RocketMiX is an open source API platform build on "classic" Spring and Netflix components. It contains : * a routing server * a management server (which embeds a directory of your APIs and a monitoring UI) * a Spring Boot Starter module (hosted on Maven central) RocketMiX aims to be a simplified API Plateform. To perform that, we simplified everything and just offered Linux executables instead of complex Java packages: one for the routing server and one for the management server. APIs you would build using our Spring Boot Starter module would automatically register themselves t make calls automatically routed to them. RocketMiX also offers some documentation features (with Swagger UI and OpenAPI specs), security, load-balancing and many more.
