🧩 Plugins
The bot supports loading external plugins.
Specifying plugins to load
Plugins can be loaded either from local files or NPM. Examples:
# Local file
plugins[] = ./path/to/plugin.js
# NPM package
plugins[] = npm:some-plugin-package
Paths to local files are always relative to the bot's folder. NPM plugins are automatically installed on bot start-up.
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;
}
});
};
