Anda dapat menggunakan perpustakaan ini untuk meningkatkan kecepatan memuat halaman dan membuat transisi halaman yang indah. Ini memiliki beberapa fitur berikut:
Perpustakaan lain dengan tujuan serupa adalah barba.js, turbolinks atau highway. Tujuan utama pemuat halaman adalah menjadi lebih ringan dan tidak terlalu ajaib, agar lebih fleksibel dan dapat disesuaikan.

import Navigator from "./vendors/@oom/page-loader/src/navigator.js" ;
const nav = new Navigator ( async ( load , event ) => {
//Load the page
const page = await load ( ) ;
await page . replaceStyles ( ) ; //Load the new css styles defined in <head> not present currently
await page . replaceScripts ( ) ; //Load the new js files defined in <head> not present currently
await page . replaceContent ( "main" ) ; //Replace the <main> element
await page . updateState ( ) ; //Update the page status (change url, title etc)
await page . resetScroll ( ) ; //Reset the scroll position
} ) ;
//Init the navigation, capturing all clicks in links and form submits
nav . init ( ) ;
//Optionally, you can filter links and forms to disable this behaviour
nav . addFilter ( ( el ) => ! el . classList . contains ( "no-loader" ) ) ;
//For example, to disable forms:
nav . addFilter ( ( el ) => el . tagName !== "FORM" ) ;
//Subscribe to events
nav . on ( "error" , ( err ) => console . error ( err ) ) ;
//You can go manually to other url when you want
nav . go ( "https//example.com/page2.html" ) ;
//Or submit a form via ajax
const form = document . getElementById ( "my-form" ) ;
nav . submit ( form ) ;
//And handle downloads (links with download attribute)
nav . download ( async ( download , event , link ) => {
link . classList . add ( "downloading" ) ;
await download ( ) ;
link . classList . remove ( "downloading" ) ;
} ) ;Sebuah instance halaman berisi informasi tentang halaman yang dimuat. Ia memiliki metode dan properti berikut:
const nav = new Navigator ( async ( load , event , target , submitter ) => {
//By clicking a link, the target is the A element
//By submitting a form, the target is the form but you can get the submitter element (the button being pressed)
const trigger = submitter || target ;
trigger . classList . add ( "loading" ) ;
const page = await load ( ) ;
//Replace an element in the document with the same element in the page
await page . replaceContent ( "#content" ) ;
//Append the children of the loaded page to the same element in the document
await page . appendContent ( "#content" ) ;
//Remove content from the document
await page . removeContent ( "#content > .unwanted" ) ;
//Change the css styles used in the new page (<link rel="stylesheet"> in <head>).
await page . replaceStyles ( ) ;
//Change the js styles used in the new page (<script src="..."> in <head>).
await page . replaceScripts ( ) ;
//Performs a document.querySelector in the page. Throws an exception on empty result
await page . querySelector ( "p" ) ;
//Performs a document.querySelectorAll in the page. Throws an exception on empty result
await page . querySelectorAll ( "p" ) ;
//Runs a history.pushState changing the url and title.
await page . updateState ( ) ;
//Reset the page scroll to top (or to the #target element)
await page . resetScroll ( ) ;
page . dom ; //HTMLDocument with the content of the page
page . url ; //The url of the loaded page
page . status ; //The http status code of the ajax response
trigger . classList . remove ( "loading" ) ;
