This is a template for deploying Discord4J bots on Railway. It is based on the example Maven / Spring project from the example repository

There are, also a few differences:

• Java version 17
• Discord4J version 3.2.3
• Built-in guild command support
• Environment variables supported through .env

In order to add a guild command, you can add a folder to src/main/resources/commands/guild/, which must be named with the ID of the guild you wish to register commands for. Inside that folder, you can put normal command.json files.

It's quite normal to have a .env file in your project with all the environment variables that matter only for this project, so you can test locally. I've done most of the work for you. you can simply create a file (called .env) and place it in the root folder of your project (next to Dockerfile and pom.xml). You can then reference this variable in application.properties like a real environment variable, and reference the application.properties variable inside your code using the @Value-annotiation. You can find an example of this inside the Bot class.

Never commit the .env file to git!
