Static Forms Pages Plugin
The Static Forms Pages Plugin intercepts all form submissions made which have the data-static-form-name attribute set. This allows you to take action on these form submissions by, for example, saving the submission to KV.
Installation
$ npm install @cloudflare/pages-plugin-static-forms
Usage
functions/_middleware.tsimport staticFormsPlugin from "@cloudflare/pages-plugin-static-forms";
export const onRequest: PagesFunction = staticFormsPlugin({ respondWith: ({ formData, name }) => { const email = formData.get('email') return new Response(`Hello, ${email}! Thank you for submitting the ${name} form.`) }
});
public/sales-enquiry.html<body> <h1>Sales enquiry</h1> <form data-static-form-name="sales"> <label>Email address <input type="email" name="email" /></label> <label>Message <textarea name="message"></textarea></label> <button type="Submit"> </form>
</body>
The Plugin takes a single argument, an object with a respondWith property. This function takes an object with a formData property (the FormData instance) and name property (the name value of your data-static-form-name attribute). It should return a Response or Promise of a Response. It is in this respondWith function that you can take action such as serializing the formData and saving it to a KV namespace.
The method and action attributes of the HTML form do not need to be set. The Plugin will automatically override them to allow it to intercept the submission.
