method-override-middleware

Method override middleware for Remix. It allows HTML forms to simulate PUT, PATCH, and DELETE requests using a hidden form field.

Features

• Form Method Overrides - Translate posted form fields into request methods
• HTML Form Friendly - Supports REST-style routes from standard browser forms
• Configurable Field Name - Choose a custom override field key

Installation

npm i remix

Usage

This middleware runs after the formData middleware and updates the request context's context.method with the value of the method override field. This is useful for simulating RESTful API request methods like PUT and DELETE using HTML forms.

import { createRouter } from 'remix/router'
import { formData } from 'remix/middleware/form-data'
import { methodOverride } from 'remix/middleware/method-override'

let router = createRouter({
  // methodOverride must come AFTER formData middleware
  middleware: [formData(), methodOverride()],
})

router.delete('/users/:id', async (context) => {
  let userId = context.params.id
  // Delete user logic...
  return new Response('User deleted')
})

In your HTML form:

<form method="POST" action="/users/123">
  <input type="hidden" name="_method" value="DELETE" />
  <button type="submit">Delete User</button>
</form>

Custom Field Name

You can customize the name of the method override field by passing a fieldName option to the methodOverride() middleware.

let router = createRouter({
  middleware: [formData(), methodOverride({ fieldName: '__method__' })],
})

<form method="POST" action="/users/123">
  <input type="hidden" name="__method__" value="PUT" />
  <button type="submit">Update User</button>
</form>
