• The frontend folder contains the source code for the frontend pages. The frontend is built using Next.js and Shadcn UI.
• The core folder is the core of the entire project, including a series of core logic and functionalities, such as the web server and backend APIs.
• Folders starting with fabric- are Fabric implementations for different Minecraft versions.
• Folders starting with forge- are Forge implementations for different Minecraft versions.
• Folders starting with neoforge- are Neoforge implementations for different Minecraft versions.
• Folders starting with spigot- are Bukkit implementations for different versions of Minecraft.
• Folders starting with folia- are Folia implementations for different versions of Minecraft.

After the plugin / mod is initialized, the program will start a web server on the specified port (default is 3000), which includes both the frontend and backend APIs.

In the development environment, the frontend page is served on port 3001, and it will directly connect to a hard-coded backend API URL http://localhost:3000 (see frontend/lib/api.ts). Therefore, when developing and debugging the frontend page, your backend web server, that is, the port configured by the plugin / mod, should be set to 3000.

Preparations

Before getting started, you need to install VSCode and IntelliJ IDEA. The following guide will assume that you are using these two code editors.

Then, you also need to install Node.js and jdk.

After preparing the development environment, you can create a fork of this repository on GitHub.

Next, clone the repository using the following command:

git clone https://github.com/<your-username>/opanel.git

Install dependencies

After cloning the repository, you need to download all the dependencies to run the source code.

Gradle Dependencies

1. Open the project with IntelliJ IDEA, and IDEA will automatically start a sync task to download dependencies.

2. After the task is completed, you can open the Gradle icon in the right sidebar to view the executable Gradle tasks. If you can find tasks like fabric/runServer in the menu, it means your Gradle dependencies have been correctly installed.

Node.js Dependencies

1. Enter the frontend folder.

cd frontend

2. Run the following command to install the dependencies.

npm install

Development

Server-side functionality / Backend API

Fabric

Execute the Fabric task fabric/runServer for the corresponding Minecraft version in the Gradle menu. After the server has fully started, the backend API and the frontend pages in the production environment will be deployed on port 3000.

INFO

Execute the Fabric task fabric/runServer for the corresponding Minecraft version in the

Forge / Neoforge / Bukkit

Prepare a Forge / Neoforge / Bukkit server in advance for testing, then follow the guide below to build a jar file. Next, place the jar file you want to debug into the corresponding mods or plugins folder. After restarting the server (Forge / Neoforge server) or executing the /reload command (Bukkit-based server), the latest changes will be applied to your test server.

Adapt the new version

See Adaptation Guide。

Frontend

Execute the command in the frontend folder

npm run dev

Then the frontend pages in the production environment will be deployed to port 3001, and you can open http://localhost:3001 with your browser to debug the frontend.

Build source code

1. Build the frontend page

Execute the command in the frontend folder

npm run build

This step will automatically copy the bundled frontend pages to the path /core/src/main/resources/web for the build of plugins / mods.

2. Build server-side plugins / mods

Run the command in the project's root directory

.\gradlew clean build

The final built jar file will appear in the /build/libs folder.

Commit your code

git add .
git commit -m "<your-commit-message>"
git push

If you want to merge your code into the official OPanel repository, you can submit it through a Pull Request.
