Middleware

The zely is based on the osik aimed at light weight and speed. Reading the osik documentation will help you understand.

#Middleware Usage

Middleware in Zely is a function that has access to the request object (req), the response object (res), and the next middleware function in the application’s request-response cycle. Here's an example of a middleware function:

import { Middleware } from 'zely';
 
export const Message: Middleware = (req, res, next) => {
  (req as any).message = 'Hello World!';
  next();
};

export default [
  GET((ctx) => {
    ctx.send(ctx.request.message);
  }),
];

This middleware function, named Message, adds a property message to the request object and assigns it the value 'Hello World!'. The next() function call is used to pass control to the next middleware function.

Middleware Registration

To use the middleware, you need to add it to the config.middlewares array in your Zely configuration file:

import { Message } from './middlewares/message';
 
export default defineConfig({
  middlewares: [Message],
  // ...
});
