海外TECH	DEV Community	Single Page Application Routing Using Hash or URL	https://dev.to/thedevdrawer/single-page-application-routing-using-hash-or-url-9jh	Single Page Application Routing Using Hash or URLOne of the most asked code questions during a front end interview is Can you create a single page application with routes without a framework In this tutorial I show you how to create a custom routing system for your single page application using either the hash or URL method without a framework This tutorial shows you how to build a Single Page App using vanilla JavaScript I show you how to implement client side routing both ways hash or URL in an easy to use format that can be replicated for any project View This On YouTube Folder StructureWe are using a basic HTML structure You can set up your files however you like but for the sake of this tutorial you can replicate what I have below index html templates html index html about html contact html js router js Let s Create Our HTMLWe are going to create a basic HTML document to serve as the main page On this page we are going to have a nav section and a content section You can build this out however you want but note the lt nav gt lt nav gt tags are used for URL routing so your nav needs to be present within those tags if you are going the URL method lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta http equiv X UA Compatible content IE edge gt lt meta name viewport content width device width initial scale gt lt title gt lt title gt lt head gt lt body gt lt nav gt lt nav gt lt div id content gt lt div gt lt body gt lt html gt Creating the JS FileBefore the lt body gt closing tag you need to add this reference to the JS file you created above lt script src js router js gt lt script gt Option One URL RoutingFirst we are going to go over how to do this with URL routing This means that your links will look like about This is the typical look of a URL the hash method uses to break up the pages I will go over that further down Use Case WebsitesThis option is better for SEO and is more user friendly NOTE There are some downsides to using this method You need to configure the webserver to serve the index html for SPA Route Paths You can do this at the server level but if you are using something like VS Code LIVE SERVER you cannot This means if you navigate directly to about the server will not render the file as it needs to load the index html scripts first You can modify your htaccess file to accomplish this Add the HTML navigationAdd the following between the lt nav gt lt nav gt tags in your index html file lt a href gt Home lt a gt lt a href about gt About lt a gt lt a href contact gt Contact lt a gt Add the navigation links in HTMLNow let s get started on the JS First we want to make any link in the lt nav gt lt nav gt tags use our routing create document click that watches the nav links onlydocument addEventListener click e gt const target e if target matches nav a return e preventDefault route Create the RoutesEach route will have an object array associated with it This will tell the script what the URL reference is as well as what template title and description are to be used const routes template templates html title description Page not found template templates index html title Home description This is the home page about template templates about html title About Us description This is the about page contact template templates contact html title Contact Us description This is the contact page Create a function that watches the URL and calls the urlLocationHandlerconst route event gt event event window event get window event if event argument not provided event preventDefault window history pushState state unused target link window history pushState event target href locationHandler Create a function that handles the URL locationconst locationHandler async gt const location window location pathname get the url path if the path length is set it to primary page route if location length location get the route object from the urlRoutes object const route routes location routes get the html from the template const html await fetch route template then response gt response text set the content of the content div to the html document getElementById content innerHTML html set the title of the document to the title of the route document title route title set the description of the document to the description of the route document querySelector meta name description setAttribute content route description Finishing The ScriptLastly we need to call the function when the page is first loaded or else the home page will not work unless it is clicked on We also need to add a watcher for the URL changes so the script knows when to show new content add an event listener to the window that watches for url changeswindow onpopstate locationHandler call the urlLocationHandler function to handle the initial urlwindow route route call the urlLocationHandler function to handle the initial urllocationHandler Option Two Hash RoutingPlease replace the content of your router js file with the following code if you are using the hash method Now on to the second option Hash routing is more common if you are using a framework but if you are creating it from scratch the negative SEO benefit may make you shy away This means that your links will look like about instead of the typical URL method above For some this URL type may not be optimal due to it being so different than what your users are used to Otherwise the code is very similar to the URL method even shorter Use Case Apps Landing PagesNOTE There are some downsides to using this method sing hashes may not be the best route for SEO and it may also be unusual for some users which may make them not use the website Add the HTML navigationAdd the following between the lt nav gt lt nav gt tags in your index html file lt a href gt Home lt a gt lt a href about gt About lt a gt lt a href contact gt Contact lt a gt Create the RoutesThe hash routes look very similar to the URL routes above You can reuse this part of the script The difference is mainly how the route link key is defined const routes template templates html title description Page not found template templates index html title Home description This is the home page about template templates about html title About Us description This is the about page contact template templates contact html title Contact Us description This is the contact page Create a function that handles the URL locationconst locationHandler async gt get the url path replace hash with empty string var location window location hash replace if the path length is set it to primary page route if location length location get the route object from the routes object const route routes location routes get the html from the template const html await fetch route template then response gt response text set the content of the content div to the html document getElementById content innerHTML html set the title of the document to the title of the route document title route title set the description of the document to the description of the route document querySelector meta name description setAttribute content route description Finishing The ScriptAgain we need to call the function when the page is first loaded or else the home page will not work unless it is clicked on We also need to add a watcher for the hash changes so the script knows when to show new content create a function that watches the hash and calls the urlLocationHandlerwindow addEventListener hashchange locationHandler call the urlLocationHandler to load the pagelocationHandler ConclusionSo while there are many ways to do this these are the you need to know to make you a better frontend developer Once you know these you can move on to React or Vue frameworks So hopefully these simple yet crucial learning methods helped you pass that dreaded interview question at the beginning of the article good luck	2022-03-26 20:06:59
