Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
window.fetch polyfill
The global fetch function is an easier way to make web requests and handle
responses than using an XMLHttpRequest. This polyfill is written as closely as
possible to the standard Fetch specification at https://fetch.spec.whatwg.org.
Installation
Available on Bower as fetch.
$ bower install fetch
You'll also need a Promise polyfill for older browsers.
$ bower install es6-promise
Usage
The fetch function supports any HTTP method. We'll focus on GET and POST
example requests.
HTML
fetch('/users.html')
.then(function(response) {
return response.text()
}).then(function(body) {
document.body.innerHTML = body
})JSON
fetch('/users.json')
.then(function(response) {
return response.json()
}).then(function(json) {
console.log('parsed json', json)
}).catch(function(ex) {
console.log('parsing failed', ex)
})Response metadata
fetch('/users.json').then(function(response) {
console.log(response.headers.get('Content-Type'))
console.log(response.headers.get('Date'))
console.log(response.status)
console.log(response.statusText)
})Post form
var form = document.querySelector('form')
fetch('/query', {
method: 'post',
body: new FormData(form)
})Post form fields
fetch('/query', {
method: 'post',
body: {
name: 'Hubot',
login: 'hubot'
}
})Post JSON
fetch('/users', {
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({
name: 'Hubot',
login: 'hubot',
})
})File upload
var input = document.querySelector('input[type="file"]')
var form = new FormData()
form.append('file', input.files[0])
form.append('user', 'hubot')
