🧩 Plugins

The bot supports loading external plugins.

Specifying plugins to load

For each plugin file you'd like to load, add the file path to the plugins option. The path is relative to the bot's folder. Plugins are automatically loaded on bot startup.

Creating a plugin

Plugins are simply .js files that export a function that gets called when the plugin is loaded.

For details about the function arguments, see Plugin API below.

Example plugin

This example adds a command !mycommand that replies with "Reply from my custom plugin!" when the command is used inside a modmail inbox thread channel.

module.exports = function({ bot, knex, config, commands }) {
  commands.addInboxThreadCommand('mycommand', [], (msg, args, thread) => {
    thread.replyToUser(msg.member, 'Reply from my custom plugin!');
  });
}

(Note the use of object destructuring in the function parameters)

Example of a custom attachment storage type

This example adds a custom type for the attachmentStorage option called "original" that simply returns the original attachment URL without rehosting it in any way.

module.exports = function({ attachments }) {
  attachments.addStorageType('original', attachment => {
    return { url: attachment.url };
  });
};

To use this custom attachment storage type, you would set the attachmentStorage config option to "original".

Example of a custom log storage type

This example adds a custom type for the logStorage option called "pastebin" that uploads logs to Pastebin.

module.exports = function({ logs, formatters }) {
  logs.addStorageType('pastebin', {
    async save(thread, threadMessages) {
      const formatLogResult = await formatters.formatLog(thread, threadMessages);
      const pastebinUrl = await saveToPastebin(formatLogResult); // saveToPastebin is an example function that returns the pastebin URL for the saved log
      return { url: pastebinUrl };
    },

    getUrl(thread) {
      return thread.log_storage_data.url;
    }
  });
};

Plugin API

The first and only argument to the plugin function is an object with the following properties:

Property Description
bot Eris Client instance
knex Knex database object
config The loaded config
commands An object with functions to add and manage commands
attachments An object with functions to save attachments and manage attachment storage types
logs An object with functions to get attachment URLs/files and manage log storage types
hooks An object with functions to add hooks that are called at specific times, e.g. before a new thread is created
formats An object with functions that allow you to replace the default functions used for formatting messages and logs

See the auto-generated Plugin API page for details.

Plugin API stability

Bot releases may contain changes to the plugin API. Make sure to check the CHANGELOG before upgrading!
