What is JamStack, Gatsby and how it can improve your Web Experience?

Are you tired of the constant struggle to improve site performance due to continuously evolving modern standards? Do all the server settings for various events and the security headaches because of your web resource give you nightmares?

And is the constant obsolescence of your technology stack, which causes even the best programmers to give up working on your site, making you lose faith in all the good in this world?

Well, we’ve got great news for you!

A new technique has emerged that can combine all these capabilities in one place and provide you with a fast transition from your existing platform without any significant waste of time or money.

What is JamStack?

The JAM in JamStack stands for: «J» — JavaScript, «A» — API, «M» — markup.  

Based on the decryption of the abbreviation, it becomes clear that to create a static site that won’t be inferior to a dynamic one we need only 3 components:

  • JavaScript, which enables interactivity to the site;
  • API, which is the source of information used by the site;
  • Markup, which is some kind of content generator or, as some people call it, a “template engine” that allows you to create page layout. 

JamStack is not about specific technologies. It is a methodology or approach, offering a variety of tools for the creation of static sites. It’s a new way of building apps and websites that results in better performance, a lower cost of scaling, higher security, and a better developer experience.

Why JamStack? 4 Benefits

Works Better and Faster  

It can generate pages at deploy time instead of building them on the fly. Plus, it minimizes the time to the first byte by pre-building files over a CDN.

Makes Your Site Scalability Easier and Cheaper 

You can swap one technology for another without needing to replace your whole website: no need to kill your APIs, your hosting strategy, all your builds, or the massive amount of content you store in your CMS.  

No Worries About Security

As you delegate your server-side processes and database operations, you reduce the risks and vulnerabilities of your web site.  

Makes Things So Much Easier for Developers 

Developers can now focus on the Frontend part and debugging without needing to maintain architecture. It ensures their work is done faster. 

What Is GatsbyJS?

Gatsby is a free and open-source React-based framework that helps developers build rocket fast sites and apps using JamStack. You can shift from any existing web project built on Drupal, Magento, WordPress, and more to GatsbyJS by simply re-writing all the Frontend based on React. Eventually, you’ll get a blazing fast, scalable, and safe project you can place on any CDN in any part of the world.

6 Main Benefits of Gatsby

Modern web tech, no headaches.

Use the power of the latest web technologies, such as Webpack, React.js, CSS, modern JavaScript, and more

Pull your data to build

Thanks to the rich data plugin ecosystem, you can build sites with the data you want, either from one or many sources. You can take data from APIs, SaaS services, headless CMSs, databases, and file systems, etc. and put it directly into your pages with GraphQL.

Scale it to the moon and back   

Gatsby.js is exceptionally scalable. No more complicated deploys with databases and servers, no more expensive and time-consuming setups. Forget about maintenance and scaling fears. Gatsby.js builds your site as “static” files that can later be easily deployed on dozens of services.

Your website is ready for the future

The future of the web is rapidly changing. It is mobile, rocket fast, and highly scalable. There’s no more division between websites and web apps. Gatsby.js is a universal JavaScript framework that will make your websites future-proof. 

Power up with PWA 

Gatsby.js is a Progressive Web App generator. Every site is an app, and every web app is a site. Users get a top-notch user experience and can save sites right to their home screens. Offline access, extreme speed, user-friendliness. 

Speed past the competition

Gatsby.js builds the fastest possible website. It loads only the essentials – HTML, JavaScript, CSS, and data. It pre-builds pages and puts them into a global cloud of servers, ready to be delivered instantly to your users wherever they are. This makes clicking around the site feel blazing fast. 

Gatsby’s Restrictions

If you are wondering if there are any limitations to the technology, the answer is  yes. Gatsby’s central principle of operation is the generation of static files, so this process can take quite a while, depending on the number of pages. So sites that have fewer than 5,000 pages can easily switch to Gatsby. However, those sites with 10,000 pages may need more time, advanced settings, and some hassling around to transit to Gatsby. To ensure stable operation, larger sites may need to be divided into smaller ones, so that the generation time does not exceed the allowed limits.

If you want to take full advantage of the modern technology stack, but you have a big website exceeding 10,000 pages, check out why you need server-rendered technologies in your project.
