PJAX

This is my own condensed pjax (pushstate + ajax) library for super fast load times, has no dependencies and no additional server requirements

If you want to see a demo, have a look at my github pages site!

Installation

This is available as a package on npm so you can add this to your project by using npm or yarn

npm

npm install z-pjax

yarn

yarn add z-pjax

Usage

In your main JavaScript file, import the class, setup the pjax object and then attach any functions that need to go onload with pjax.onload, which is a wrapper for window.onload and when the pjax request has finished

import PJAX from './src/PJAX';

let pjax = new PJAX();

let x = 0;

pjax.onload(() => {
    x++;
    
    console.log(`Loaded ${x} times with pjax`);
});

pjax.setup();

Selecting data to PJAX

This library is able to replace various different elements on a webpage, it currently replaces the main content (body), the title tag, and then any matching attributes that you want.

Changing the container and links

The main functionality of PJAX is used in the container and links properties, and there are two ways of changing what these are (the defaults are .body and .pjax-link

Constructor

let pjax = new PJAX('main', 'a');
pjax.setup();

After Initialisation

let pjax = new PJAX();

pjax.container = 'main';
pjax.links = 'a';

pjax.setup();

Changing text content outside of the container

Sometimes elements outside of the container will need to change as well, such as the title of the page, or the h1 if it exists outside, in order to change what elements have their textContent property changed, the following is needed (these are also the defaults)

let pjax = new PJAX();

pjax.replace.textContent = [
    'title'
];

pjax.setup();

Changing attributes outside of the container

Sometimes attributes of elements will also need to be changed, particularly ones related to SEO or Social media, this library also covers those, but if you need to change the behaviour, you'll need to do the following (these are also the defaults)

let pjax = new PJAX();

pjax.replace.attribute = [
    {
        selector: 'meta[name$="title"]',
        attribute: 'content'
    },
    {
        selector: 'meta[name$="description"]',
        attribute: 'content'
    },
    {
        selector: 'meta[property^="og:"]',
        attribute: 'content'
    },
    {
        selector: 'meta[property^="article:"]',
        attribute: 'content'
    },
    {
        selector: 'link[rel="canonical"]',
        attribute: 'href'
    }
];

pjax.setup();

Notes

This class uses the forEach method for nodelists, so if you need to support IE11 for some reason, add this polyfill in

if(typeof NodeList.prototype.forEach === 'undefined'){
    /* Polyfill for nodelist foreach for ie11 */		
    NodeList.prototype.forEach = function (callback, scope){
        for(var i = 0; i < this.length; i++){
            callback.call(scope, this[i], i);
        }
    };
}

Building

If for some reason, you want to build the files for this library yourself (instead of using the dist folder), you can run the following commands to work locally with it

Note: Don't forget to install the dev dependencies

**Running gulp

gulp # This command builds the files, then watches for any changes in the src directory
gulp build # This command only builds the files
gulp watch # This command only watches the files
