When creating plugins, you should avoid using Deno or Node specific features to make your plugin compatible with both the JSR and NPM package.

​
CLI Command

Terminal
blitz plugin
You will then be asked questions to help Blitz create the config file for you.

​
Questions

​
Name
string
required
The name of your plugin
​

​

​
Files

​
Structure

Your plugin should have a similar structure to this.
File Structure
├── /commands
├── /events
└── blitz.config.yaml

​
Uses

​
/commands
Holds the commands for your plugin.
​
/events
Holds the events for your plugin.
​
blitz.config.yaml
required
Holds the manifest data and config for your plugin.

​
blitz.config.yaml

The blitz.config.yaml file contains all the metadata for your plugin. You can also add config valuese to this to allow users to customize your plugin.

​
Example blitz.config.yaml

blitz.config.yaml
name: my_plugin
description: My totally cool plugin
version: 1.0.0

​
Manifest Values

​

required
The name of your plugin
​
description

​
version

​
Adding Config

You can add config values inside of your plugins blitz.config.yaml file which will be passed into your plugins commands and events.
blitz.config.yaml
name: my_plugin
description: My totally cool plugin
version: 1.0.0

config:
    cool_message: "This is a cool message"
This basic example of a blitz.config.yaml file contains a config key called cool_message. In any of the plugins commands or events you can access this.
Event.ts
console.log(config.cool_message)
This would log This is a cool message.

​
Commands

All commands for a plugin must go inside of the /commands folder in the root of the plugin.
Commands are built using the discord.js SlashCommandBuilder class.

​
Example Command

ping.ts
import { SlashCommandBuilder } from "npm:discord.js";

export default {
  data: new SlashCommandBuilder()
    .setName("ping")
    .setDescription("Pong!"),
  action: async (client, interaction) => {
    await interaction.reply({ content: `Pong!` });
  },
};
Notice the import from npm:discord.js? This is a specific deno import which allows us to use discord.js within deno.

​
Example Command (Config)

greet.ts
import { SlashCommandBuilder } from "npm:discord.js";

export default {
  data: new SlashCommandBuilder()
    .setName("greet")
    .setDescription("Greet someone"),
  action: async (client, interaction, config) => {
    await interaction.reply({ content: `${config.greetMsg}` });
  },
};
For this command to work you would have to add greetMsg to your blitz.config.yaml file.
blitz.config.yaml
name: my_plugin
description: My totally cool plugin
version: 1.0.0

config:
    greetMsg: "Welcome to the server!"

​
Events

All events for a plugin must go inside of the /events folder in the root of the plugin.

​
Example Event

ready.ts
export default {
  event: "ready",
  once: true,
  action: async (client) => {
    console.log(`${client.user.username} is online!`);
  },
};

​
Example Event (Config)

message.ts
export default {
  event: "messageCreate",
  once: true,
  action: async (client, config, message) => {
    message.reply(`${config.message}`);
  },
};
For this event to work you would have to add message to your blitz.config.yaml file.
blitz.config.yaml
name: my_plugin
description: My totally cool plugin
version: 1.0.0

config:
    message: "I replied to a message!"
