MiddlewareFunction

Middleware functions allow you to run code before your interaction handlers. They are useful for logging, authentication, database setup, and more.

Definition

type MiddlewareFunction<Context extends BaseInteractionContext = BaseInteractionContext> = (
  context: Context,
  next: () => Promise<void>
) => Promise<Response | void> | Response | void;

Example

const myMiddleware: MiddlewareFunction<MyContext> = async (c, next) => {
  console.log(`Received interaction: ${c.req.method} ${c.req.path}`);
  await next();
};

bot.use(myMiddleware);

Notes

• Middleware functions must call await next() to continue execution to the next middleware or handler.
• If a middleware returns a Response (e.g., for error handling), the execution chain stops there.
• Honocord’s use method accepts multiple middleware functions.
