Lion is a plugin-oriented Discord bot that utilizes Discord.js and TypeScript. Lion was created originally to satisfy the needs of server automation within the UCF CS Discord.
The simplest way to get started off with developing the Lion codebase is by cloning the project:
git clone https://github.com/cs-discord-at-ucf/lion.git
Install dependencies via NPM:
npm install
Create a Discord Bot in the Discord Developer Portal. Make sure that your bot has the "Server Members Intent" enabled.
Create a .env file within the root directory of the project (reference the .env.sample sample file) with your Discord application token:
DISCORD_TOKEN=your_token_here. Be sure to remove any secrets from the .env that you are not using, ex. MONGO_PASS=x.
Execute the following command to launch Lion:
npm run watch
All subsequent saved changes made within the /src directory will make Lion automatically rebuild while the watch command is running.
Navigate to the /src/app/plugins directory and create a new file following the specific schema:
example.plugin.ts
For ease of use, it's recommended that your plugin name is in all lowercase and in snake_case.
Your plugin must be the default export of the file: e.g. export default class ExamplePlugin
Here's a skeleton for how a basic plugin should look:
import { Plugin } from '../../common/plugin';
import { IContainer, IMessage, ChannelType } from '../../common/types';
export default class ExamplePlugin extends Plugin {
public commandName: string = 'example';
public name: string = 'Example Plugin';
public description: string = 'An example plugin to show how awesome Lion is!';
public usage: string = 'example';
public permission: ChannelType = ChannelType.Bot;
constructor(public container: IContainer) {
super();
}
public async execute(message: IMessage, args?: string[]) {
// Your logic here.
}
}Again, this is a basic skeleton. It is suggested to read the abstract Plugin class to fully know what is possible within a plugin, which is located in /src/common/plugin.ts.
And that's it! You have successfully created your first plugin with Lion!
