    Inferno

    Inferno

    React-like JavaScript library for building modern user interfaces

    ...Inferno has a partially synthetic event system, instead opting to only delegate certain events (such as `onClick`). Inferno doesn't support React Native.

Inferno provides lifecycle events on functional components. This is a major win for people who prefer lightweight components rather than ES2015 classes.

    BedrockConnect

    Join any Minecraft Bedrock Edition server IP on Xbox One

    On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily.
