remote-form
A function that will enable submitting forms over AJAX.
The function will make a request based on the form using window.fetch with the payload encoded as URL parameters if the form method is a GET and FormData for all the other methods.
The request object is available in the callback function, allowing the headers and body to be modified before the request is sent.
Installation
$ npm install --save @github/remote-form
Usage
import {remoteForm} from '@github/remote-form'
// Make all forms that have the `data-remote` attribute a remote form.
remoteForm('form[data-remote]', async function(form, wants, request) {
// Before we start the request
form.classList.remove('has-error')
form.classList.add('is-loading')
let response
try {
response = await wants.html()
} catch (error) {
// If the request errored, we'll set the error state and return.
form.classList.remove('is-loading')
form.classList.add('has-error')
