Jamstack - deciphered!

Developers came up with the term JAMstack somewhere in 2016 to name a different approach to building static websites. This approach included decoupling the back end from the front end, separating the build stage from the hosting stage, and using modern CDNs' advantages.

The J A M in the Jamstack initially stood for JavaScript, APIs, and Markup. The term outgrew itself and became broader, now including best practices behind it.

Currently, Jamstack refers to a modern web development architecture approach created to provide better performance, more security, cheaper scaling costs, and a smoother developer experience.

The paradigm change in Jamstack lies in taking everything to the client-side and build-time level, and not doing anything at run time on a server-side level, thus making the web environment highly optimized and more secure.

Jamstack separates the frontend and backend; while in a traditional setup, both are combined together. Such a practice makes things complex for scaling and dependencies between front-end and backend programmers. In contrast, Jamstack allows a programmer to think in terms of separation, meaning that the frontend developer does not have to think much about the backend APIs.

In Jamstack, websites pre-render their pages during the time of building, while the conventional method entails pre-rendering of the pages at the time of receiving user requests.

The fact that Jamstack has enhanced security, scalability, as well as hosting choices can be another motivating factor to consider when comparing the two options since using dynamic server resources is not necessary.

Using up-to-date tools and technologies in the construction of websites, including the usage of headless CMS platforms and static site generators, can be seen as an advantage, especially considering that monolithic CMS or any other server-side rendering system can hinder developers in some way.

Traditional approaches may prove beneficial in some cases where there is a need for dynamic websites.

The Jamstack architecture relies on tools such as Gatsby, Next.js, Nuxt.js, Hugo, and Jekyll to generate HTML, CSS, and JavaScript files for each webpage. These are the statically built files that can then be deployed to a host.

Jamstack websites deliver pre-compiled content and assets faster because no database query is needed, and hence the site delivers cached files from a content delivery network (CDN).

When more functionalities are required, APIs are created in a Jamstack application where data is retrieved from the APIs using JavaScript.

The build and deployment process for a Jamstack website is relatively simple. The first step involves writing code, while the second involves providing content.

In case of any changes in the source code and/or content, the static site generator will initiate a new build process to generate updated static files. This can be achieved using version control services such as Git, which usually serve as a trigger for builds.

First, the new version of the website is generated into static files either directly on the hosting provider's server or using an integration service. Then, the files get uploaded to a CDN. In most cases, modern providers such as Netlify do this automatically after any pushes to a selected branch in the repository.

Since all pages have already been prepared in advance, they get delivered to the end-users by the CDN at very high speeds due to the absence of any time-wasting real-time page construction. When a new build gets uploaded to the server, modern CDNs instantly remove their current cache and replace it with newly generated files.

While the result of the Jamstack-built websites is static files, those files are not without dynamic functionalities, functionalities like forms, comments, payment gateways, etc., usually handled by third-party APIs (application programming interfaces). Static, in the case of Jamstack, does not mean still but rather server-free. The browser does not need the help of servers to handle dynamic parts first. This feature comes with quite a few business benefits.

• Security - Jamstack provides built content and also enables read-only hosting, thereby minimizing the window of attacks.
• Scalability - It is easy for Jamstack to handle high traffic volumes. This is because the content provided is provided directly from a CDN without any sophisticated processes, thus ensuring resilience against high traffic and making them scalable.
• Performance - The performance of Jamstack sites can be increased by providing pre-built pages that will have been generated before deployment to make them available for delivery from a CDN to end-users without expensive infrastructures being required.
• Maintainability - The low hosting process involved in Jamstack sites makes them easier to maintain.
• Portability - Since Jamstack sites have already been pre-rendered, they can be easily hosted by different service providers without locking in any particular one.
• Developer experience - Jamstack development can be easily handled by developers who can develop the web application using any of the many common tools and methodologies.
• Efficiency - Jamstack project management can be done very efficiently due to the simple development process using common technologies and tools.

To begin your project, choose a static site generator that matches your project's needs and your development preferences. Take into account factors such as programming language, community support, available plugins, and ease of use.

If your project involves content management, select a headless CMS that provides an API for content delivery. Alternatively, you can use a version control system like Git to manage content.

Create the frontend of your Jamstack project using HTML, CSS, and JavaScript. Use the capabilities of your chosen static site generator to build components, templates, and layouts. Ensure responsive designs and optimize performance.

Identify the APIs required for dynamic functionality, use JavaScript on the client-side to request data from these APIs, and integrate it into your static files.

Choose a hosting provider or content delivery network (CDN) to deploy your Jamstack project. Popular options include Netlify, Vercel, AWS S3, Firebase Hosting, or GitHub Pages. Configure your deployment process to automatically trigger builds and updates when changes are made.

Thoroughly test your Jamstack project to ensure functionality, responsiveness, and cross-browser compatibility. Optimize your static files for performance by employing techniques like minification, code splitting, lazy loading, and caching.

Implement continuous integration and deployment (CI/CD) pipelines to automate the build and deployment process, ensuring that your project is continuously built, tested, and deployed whenever changes are pushed to your repository.

When should you use Jamstack?

• If your website primarily consists of read-only content like blogs, company pages, portfolios, or documentation, Jamstack is an excellent choice, as it efficiently serves static content.
• When performance is a critical factor, and you need your website to load fast across the globe, use Jamstack to leverage CDNs and pre-rendered content for quick delivery.
• For sites that require enhanced security, Jamstack minimizes the surface for attacks by reducing server-side processing and databases that can be exploited.
• Jamstack is suited for projects expected to scale because the static nature of the site allows for easy duplication across servers without taxing backend resources.
• Projects that benefit from modern development workflows, such as using headless CMSs, static site generators, and microservices, are a good fit.
• If you have separate teams working on the frontend and backend, Jamstack's decoupled architecture allows both teams to work independently and integrate through APIs.

Best practice for Jamstack application development can go a long way in allowing you to take full advantage of this architecture and avoid any difficulties that might come with it.

• Automation and Continuous Deployment

Develop and implement an automatic build system for your applications, utilizing CI/CD pipeline automation technologies such as those provided by GitHub, GitLab, and Bitbucket Pipelines. They allow your static website to be built and deployed automatically upon detecting code modifications.

• Incremental builds

Implement incremental builds into your application development process to shorten build times. Many static website builders offer this functionality, including Gatsby and Next.js applications hosted on their own respective clouds.

• Git-powered workflow for managing content

Make sure that the process of managing the content is powered by Git. Such an approach will give you an ability to version your content, ensure backup and rollbacks, and also allow collaboration between team members.

• Work with headless CMS

This type of CMS provides an opportunity to separate content management and site rendering. Using a headless CMS allows one to update their content dynamically and avoid rebuilding the whole site in order to deliver content across multiple platforms.

Among many options of headless CMS, Payload is worth mentioning for its flexibility and the availability of third-party integrations.

• Pick the best SSG for your needs

The choice of SSG should be made based on particular project needs like the language used or availability of plugins among other things. Some popular examples include Hugo, Gatsby, Next.js, and Jekyll.

• Make use of CDNs and edge computing

Put your website on a Content Delivery Network (CDN) so that it loads instantly regardless of where your users are geographically located. Think of using edge computing when necessary for functionalities or dynamic rendering.

• Use serverless functions for backend processing

Whenever there’s a need for any type of backend processing, such as form submission, authentication, and dynamic data fetching, make sure that you do so via serverless functions to uphold the serverless architecture.

• Practice proper security measures

Even if the Jamstack technology is considered to be inherently secure, taking additional steps towards security, such as implementing HTTPS, CORS management, serverless function security, and protecting third-party service credentials, are highly advised.

• Develop locally and deploy globally

Ensure that you develop in a local environment that mimics the production environment as much as possible. Once it’s time for deployment, consider global CDN hosting.

• SEO and accessibility planning

Make sure that your website is created with SEO in mind by incorporating metadata, semantic HTML elements, and structured data. Don’t forget about accessibility – your website needs to be accessible to everyone!

• Keep your website backed up

While using the Git-based approach will give you access to the history of changes to your project’s code, don’t neglect to back up your website’s content regularly!

The main problems associated with Jamstack can include dynamic content, SEO, build time, and complex development. But don't panic: the proper choice of tools, the use of third-party services, and effective optimization of the development process will help solve many of these problems.

Optimization for SEO

If Jamstack sites (for example, SPA applications) do not undergo special optimization for SEO, their search engine optimization capabilities can be limited due to problems with indexing content loaded via JavaScript. Server-side rendering and static site generation should be used to ensure that all site content is rendered before being indexed. Semantic markup according to HTML5 standards and schema.org will also help optimize your site for SEO.

Dynamic functionality

When it comes to incorporating various types of dynamic functionality on Jamstack sites, there may be difficulties since everything needs to work client-side. Therefore, you need to employ third-party services and APIs for some tasks.

Builds and deployment

With an increase in content and complexity, a Jamstack website might require more time during builds. In order to minimize delays caused by slow builds, employ incremental builds, parallel building, and building only modified pages. Pick SSGs and hosts that accommodate such solutions.

Content management

Since Jamstack websites usually involve headless CMSs, writers will not be used to managing content outside of their content editors. Therefore, choose a headless CMS with a simple interface for authors to edit their content easily. Design an intuitive editing environment for the content creator or opt for static site CMS.

Complexity

A large number of services and APIs could increase the level of difficulty in managing and developing the website. Solution to this problem: Ensure thorough documentation of all services employed and limit service integration. Develop standard practice within your team regarding API management.

Database integration

Since Jamstack sites do not traditionally connect to databases, this may pose a challenge to those who have websites that rely extensively on database connectivity. This can be solved by employing serverless functions or services whose operation involves some form of abstraction from the actual database interaction.

Form submissions

Forms can present a bit of difficulty when trying to handle them within the Jamstack framework. Since there is no way of processing the forms due to the absence of the backend, you may wish to incorporate the use of external form handler applications or serverless functions.

It is worth noting that these approaches can vary based on specific requirements for the project in question.

The Jamstack approach to creating applications on the internet is an effective and efficient process with plenty of advantages and minimal disadvantages, helping to make a website a much better experience for yourself and your visitors.

The really exciting thing about it is the evolving ecosystem and community. Though great as these technologies currently are, the development teams behind these Jamstack-based websites will not stop at anything but the sky, making the world wide web a much better place for everybody.
