✈️ Jet

Note

Jet is still very much WIP, Jet should NOT be used for normal servers (yet!)

A brand new Minecraft server software made from scratch that aims to be multithreaded, user-friendly and to have a modern API.

Jet does not have any vanilla features reimplemented, such as combat or fluids, making it good for simple minigame servers.

Background

What does Jet do over other servers?

(Craft-)Bukkit based software (Spigot/Paper)

Minecraft minigame servers are popular for a long time. The oldest ones started from simple minigame servers and ended up with a large server networks.

Since Minecraft release, a lot features were added, affecting server performance. However, minigame servers don't need all of those features. Some servers may also want to have a multi-threaded solution, which Minecraft doesn't have. That's why server software like Jet and Minestom came up.

Jet doesn't have any vanilla features re-implemented by default, allowing for developers to implement their own mechanics and vanilla mechanics, but only these, which they need.

Our server software isn't ideal however. We recommend it for people, for which it's faster to add vanilla mechanics that they need than removing existing mechanics from (Craft-)Bukkit bassed software.

Minestom

• Simplicity Unlike Minestom, Jet uses an approach more similar to that of Spigot and Paper, the server is just a .jar that you download and run like a normal application, and after which add plugins to. One downside of this is that it can often lead to clashes between plugins and generally make it harder to develop for, Jet aims to solve this with multiple approaches that you will see below.
• Customizability As mentioned Jet will use multiple ways to better integrate your plugin with the server:
  • Everything is an event In Jet everything is an event, as you may know from other APIs, events have priorities like FIRST, NORMAL and LATE, unlike others Jet has an extra priority named SERVER, this priority will ONLY be used by Jet, and allows the developer to change multiple things about the event either before or after it is handled by Jet. Some features utilizing events are: ALL packets, both outgoing and ingoing, world loading and simple features like inventories, commands etc.
• Quality of Life Jet includes many QoL features that you may or may not have seen in other servers, some of which include: setting a block only for a specific player, automatic resourcepack creation, any many more!

Install

To install Jet you need to download a server jar file from Github, which you run like a normal java application.

Usage

Using Jet is not very different than Craftbukkit based software, except for not having vanilla features and their properties.

You have a basic configuration file, which contains the most important settings for the server.

If you want to implement features on your server, you need to make plugins using our API, which you put into a plugins subdirectory.

Contributing

You can contribute to Jet easily by creating pull requests, without any other needs.

To not waste your time, make sure to join our Discord server and ask if your contribution would be merged or not. You can also make that via an issue, however it may take longer to get a response.

License

All Jet components (except of API) are licensed under an AGPL 3.0 license.

License of the API however is a MIT license, allowing plugins freedom of licensing or even being close-sourced.
