Single Page Applications (SPA) is a website design approach popular for faster loading and attractive user interfaces.

When a user interacts with website, it dynamically rewrites the current page instead entire page reloading. This makes it faster than websites and web apps.

After one or two similar implementations in 2002, SPA was introduced in the same year in one US patent by Lucas Birdeau, Kevin Hakman, Michael Peachey and Clifford Yeh.

Popular SPAs: Gmail, Facebook, Google Maps, Twitter, Google Drive

You can build SPAs using frameworks like AngularJS, Ember.js, Knockout.js, Meteor.js, React, and Vue.js.

They’re heavily based on JavaScript for everything like displaying data, communicating with a server, and app logic. SPA also uses AJAX and Websockets to load and update data.

SPA

Benefits:

  • Fast as HTML, CSS, JavaScript is only loaded once
  • Easy-to-develop
  • Storage optimization
  • Easier to debug
  • Better client-side rendering
  • Limited server access
  • Faster interaction and reloading

Drawbacks:

  • JavaScript must be enabled
  • SPAs are not SEO compatible
  • Navigational complexity
  • Performance monitoring issues
  • Less secure
  • Lack of maintainability

Avoid SPA for:

  • Purely static content websites

SPAs are a good option for responsive websites and data streaming requirements.
