 ### 2. Type your Pages Plugin
 
 To create a good developer experience, you should consider adding TypeScript typings to your Plugin. This allows developers to use their IDE features for autocompletion, and also ensure that they include all the parameters you are expecting.

 In this guide, you will learn how to refactor a Worker made to intake form submissions to a Pages Function that can be hosted on your Cloudflare Pages application. [Pages Functions](/pages/functions/) is a serverless function that lives within the same project directory as your application and is deployed with Cloudflare Pages. It enables you to run server-side code that adds dynamic functionality without running a dedicated server. You may want to refactor a Worker to a Pages Function for one of these reasons:
 
 1. If you manage a serverless function that your Pages application depends on and wish to ship the logic without managing a Worker as a separate service.

 ### Refactor your Worker
 
 To refactor the above Worker, go to your Pages project directory and create a `/functions` folder. In `/functions`, create a `form.js` file. This file will handle form submissions.

 However, if you want to reply with a JSON object instead of the key-value pairs (an Array of Arrays), then you must do so manually. Recently, JavaScript added the [`Object.fromEntries`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/fromEntries) utility. This works well in some cases; however, the example `<form>` includes a `movies` checklist that allows for multiple values. If using `Object.fromEntries`, the generated object would only keep one of the `movies` values, discarding the rest. To avoid this, you must write your own `FormData` to `Object` utility instead:

-The body of a [Request](https://developer.mozilla.org/en-US/docs/Web/API/Request) can only be accessed once. If you previously used `request.formData()` in the same request, you may encounter a TypeError when attempting to access `request.body`.<br/><br/>
-To avoid errors, create a clone of the Request object with `request.clone()` for each subsequent attempt to access a Request's body.
-Keep in mind that Workers have a [memory limit of 128MB per Worker](https://developers.cloudflare.com/workers/platform/limits#worker-limits) and loading particularly large files into a Worker's memory multiple times may reach this limit. To ensure memory usage does not reach this limit, consider using [Streams](https://developers.cloudflare.com/workers/runtime-apis/streams/).

 Choosing the appropriate rendering method for Turnstile is important and effectively helps you to add it to your website while ensuring optimal performance and user experience. Both implicit and explicit rendering have their own advantages and are suited to different types of web applications.
