Web pages that dynamically update without the need for reloading

Recently, I stumbled upon slack.com and was immediately captivated by its user interface. For those unfamiliar with it, navigating the site is quite simple:

There's a sidebar on the left and a main content area on the right. When you click on an item in the sidebar, the corresponding content loads in the main area without refreshing the entire page. The selected item changes, the content updates accordingly, all seamlessly.

Even if the data changes in real-time, the display magically stays up-to-date.

What would be required to create a similar dynamic experience?

Changing URL without reloading the page
Maintaining constantly updated content

I've been exploring meteorjs lately, but surprisingly, there seems to be no mention of handling URL changes.

Absolutely! Slack is an invaluable tool that my team and I rely on every day. In fact, I find myself using it so frequently that I often prioritize checking Slack over my email.

Now, let's address your query.

Implementing URL changes without reloading the page

This task can be easily accomplished using JavaScript. Here's a quick summary:

window.history.pushState("object or string", "Title", "/new-url");

Maintaining constantly updated content

There are two main approaches to achieve this: i. Using Ajax and JavaScript ii. Utilizing sockets

i. Using Ajax and JavaScript: By setting up a setTimeout function in JavaScript, you can periodically send an Ajax request to fetch the latest data from the backend, ensuring that your content remains current.

ii. Using sockets: If you're working with Node.js, consider utilizing the popular library called socket.io for real-time message updates through websockets.

Best of luck!

To achieve dynamic data updating without refreshing the page, utilizing Ajax is essential. It can be paired with a scripting language such as PHP to continuously monitor the database's state through periodic intervals (known as a "heartbeat"). When there are changes detected, the new data can be seamlessly loaded in. One effective strategy is to include a dedicated column for a datetimestamp to optimize query efficiency and reduce strain on the database, especially when multiple users are accessing the page simultaneously.

To implement the "url changing feature but no reload," another solution could be utilizing the yield templates function of iron-router as suggested by @Kavan Pancholi.

Working with meteor makes it relatively straightforward to accomplish this without delving into Ajax and Sockets complexities.

Although unfamiliar with Slack, my understanding is that they preload/lazy load all data and only update displayed elements. Essentially, keeping all client subscriptions ready or loading them when needed for the yield template.

I will research more about Slack to ensure I grasp your objective correctly and provide any necessary clarifications.

Edit: After experimenting with Slack, incorporating yield templates with iron-router seems essential. Additionally, implementing transition effects can be achieved using _uihooks in conjunction with a loading template.

Furthermore, if you opt to utilize a framework such as angular, you will observe URLs structured like the following:

http://localhost:3000/#/chat/room

You may have noticed a similar pattern with Wikipedia where URLs resemble this format:

https://en.wikipedia.org/wiki/Cat#Cats_and_humans

The addition of that little symbol - the # - does not trigger a page refresh when included in the URL. This can be leveraged for implementing URL routing actions without navigating away from the current page. Accessing it is as simple as using window.location.hash. For instance, on the Wikipedia article, you would retrieve:

> window.location.hash
#Cats_and_humans

When paired with AJAX and event listeners, you are empowered to achieve similar functionalities.

// utilizing jQuery

// specify a callback function for when the hash changes
$(window).on('hashchange', function (e) {
  e.preventDefault();
  var hash = window.location.hash;

  // identify the container where data will be displayed and clear any existing content
  var $container = $('#container');
  $container.html('<ul></ul>');

  if (hash === '#/movies') {
    // retrieve JSON data from an endpoint and append it to the DOM
    $.getJSON('/api/movies', function (data) {
      data.each(function (el) {
        $container.append('<li>' + el.name + '</li>');
      });
    });
  }
});
