# Delay action

Customers with a Bot Management and a [Workers](https://edgetunnel-b2h.pages.dev/workers/) subscription can use the template below to introduce a delay to requests that are likely from bots.

The template sets a minimum and maximum delay, and delays requests where the bot score is less than 30 and the URI path starts with `/exampleURI`.

* [  JavaScript ](#tab-panel-7507)
* [  TypeScript ](#tab-panel-7508)

**JavaScript**

```js
// Configurable Variables
const PATH_START = "/exampleURI";
const DELAY_FROM = 5; // in seconds
const DELAY_TO = 10; // in seconds


export default {
  async fetch(request, env, ctx) {
    const url = new URL(request.url);
    const botScore = request.cf.botManagement.score;


    if (url.pathname.startsWith(PATH_START) && botScore < 30) {
      // Random delay between DELAY_FROM and DELAY_TO seconds
      const delay =
        Math.floor(Math.random() * (DELAY_TO - DELAY_FROM + 1)) + DELAY_FROM;
      await new Promise((resolve) => setTimeout(resolve, delay * 1000));


      // Fetch the original request
      return fetch(request);
    }


    // Fetch the original request without delay
    return fetch(request);
  },
};
```

**TypeScript**

```ts
// Configurable Variables
const PATH_START = '/exampleURI';
const DELAY_FROM = 5; // in seconds
const DELAY_TO = 10; // in seconds


export default {
  async fetch(request, env, ctx): Promise<Response> {
    const url = new URL(request.url);
    const botScore = request.cf.botManagement.score


    if (url.pathname.startsWith(PATH_START) && botScore < 30) {
      // Random delay between DELAY_FROM and DELAY_TO seconds
      const delay = Math.floor(Math.random() * (DELAY_TO - DELAY_FROM + 1)) + DELAY_FROM;
      await new Promise(resolve => setTimeout(resolve, delay * 1000));


      // Fetch the original request
      return fetch(request);
    }


    // Fetch the original request without delay
    return fetch(request);
  },
} satisfies ExportedHandler<Env>;
