Create a middleware

• fastro init command will generate folders and files like this.

  webapp
  ├── Dockerfile
  ├── middleware
  │   └── support.ts
  ├── public
  │   ├── favicon.ico
  │   ├── index.html
  │   └── logo.svg
  └── services
      ├── hello.controller.ts
      └── hello.template.html
  
  3 directories, 7 files
  
  

• You can access and add additional property to the request object before the controllers process it.

• Open middleware file, middleware/support.ts:

  import type { Callback, Request } from "https://raw.fastro.dev/master/mod.ts";
  export const options = {
    methods: ["GET, POST"],
  }
  export const handler = (request: Request, next: Callback) => {
    request.hello = "with middleware";
    next();
  };

What's next:

• Create static files
• Template rendering
• Data validation
• Publishing and Deployment
• Fastro API
