import { Hash } from "https://unpkg.com/better-hash-router@latest";see HTML example on Github here
or if you're using npm
Install npm i better-hash-router
// ES6
import { Hash } from "better-hash-router";
// CommonJS
const { Hash } = require("better-hash-router");Note: The
<body> </body>must be empty. all the content on each route will be parsed and injected to the<body></body>at runtime.
- First you have to initialize the library, else it'll remind you to doing so by throwing an error.
Hash.initialize();- Now you have to create a new instance of
Hash
const myRouter = new Hash("router-name");-
Now you can add new Routes to your Router instance.
route()method accepts 2 parameters.
path: a String representing the hashed path without the#. eg. if path is"#about"then remove the#. which is"about"data:String | HTMLElement | Object | Functiondata can be passed in as multiple formats. see the examples below.route()method returns the router instance. therefore the method is chainable.
Both Arguments are Mandatory.
"/"path determines the root path, which is your default path. so the contents assigned to the"/"route will be displayed when you open your page.
data: string
Hash.initialize();
const myRouter = new Hash("router-name");
myRouter.route("/", "this will be displayed on your root");data: HTMLElement
Hash.initialize();
const myRouter = new Hash("router-name");
const aboutDiv = document.createElement("div");
aboutDiv.innerHTML = "Hey this is about me";
myRouter.route("about", aboutDiv);data: { template, selector }
{
template: "absolute path to file",
selector: "css selector"
}assuming that you have an html file on
/pages/contact.htmland there is an element with idcontact-form
NOTE: Here the selector is optional.
if selector is not provided, then all the contents of the contact.html's body will be copied to the route.
Hash.initialize();
const myRouter = new Hash("router-name");
myRouter.route("contact", {
template: "/pages/contact.html",
selector: "#contact-form"
});data: Function
Hash.initialize();
const myRouter = new Hash("router-name");
myRouter.route("/", () => {
return "this data comes from a function";
});instance.route() can be chained since it returns the instance itself.
Hash.initialize();
const myRouter = new Hash("router-name");
myRouter
.route("/", "this page shows info about me")
.route("contact", "my contact info")
.route("any_other_route", "some interesting stuff");
// goto yourdomain:port/#any_other_route to see the contentinstance.open() can be used to open a path manually.
- accepts an argument
Pathas a String
const button = document.getElementById("contact-button");
button.addEventListener("click", event => {
myRouter.open("contact");
});Hash.EVENTS // all supported events can be accessed via this static property.open- fires when you open a page using instance.open(path).doneparsing- fires when a intance.route(path, data) parse a template.close- fires when theclose()method is called.error- fires when a parsing error occures on a route.
addEventListener(event, callback)
myRouter.addEventListener("open",function (event){
// your code goes here..
});onPageLoad(path, callback)
myRouter.onPageLoad("/", function (event) {
// your code goes here..
});onReady(path, callback)
myRouter.onReady("/", function (event) {
// your code goes here..
});onError(callback)
myRouter.onError(function(){
// your code goes here..
});1. route(path, data)
2. open(path)
3. fetchTemplate({template, selector})
4. onPageLoad(path, callback)
5. onReady(path, callback)
6. onError(callback)
7. addEventListener(event, callback)1. availableRoutes (getter)1. initialize()
2. isRouteDefined(path)
3. close()
4. router(name)1. availableRouters
2. isInitialized
3. availableTemplates
4. EVENTS- using a
functionas thedataargument.
function must have a
returnstatement of aStringor anHTMLElement
Hash.initialize();
const navigationRouter = new Hash("navigation");
navigationRouter.route("/", () => {
const tiles = ["skills", "projects", "about", "resume", "contact"];
const wrapper = document.createElement("div");
tiles.forEach(tile => {
const link = document.createElement("a");
a.innerHTML = tile;
wrapper.append(link)
});
return wrapper;
});- using templates from a single html file.
assuming that you have a
template.htmlfile in your root directory. and they have elements with appropriate id
Hash.initialize();
const myRouter = Hash.router("my router");
myRouter
.route("/", {template: "/template.html", selector: "#home"})
.route("about", {template: "/template.html", selector: "#about"})
.route("contact", {template: "/template.html", selector: "#contact"});If you want to manipulate the content of your routes, please note that they don't exist at the
window.onloadevent. because the routes and their contents are fetched and rendered after theonloadevent of window. so, instead of usingwindow.onload, you should use theonPageLoadeventListener on your router instance.
assuming that you already have a contact route defined on your router
myRouter.onPageLoad("contact", (event) => {
console.log("contact page has loaded");
// now you can Manipulate your DOM elements her...
