JavaScript
Handles interactivity in the browser, enhancing the pre-built page at runtime.

What is JAMstack?
Learn how pre-rendered pages and APIs fit together, and where a different rendering approach may be needed.
( the three letters )
JavaScript, APIs, and Markup.
APIs
Supply dynamic data like product catalogs, content, and user features through service calls.
Markup
Static HTML is generated ahead of requests and can be cached on a content delivery network (CDN).
The payoff
Less page-generation work per request, balanced against build times, content freshness and API dependencies.
( where it fits )
Common uses for pre-rendered pages.
Marketing sites
Serve landing pages and published content from a CDN, with crawlable HTML and an update process.
eCommerce storefronts
Pair a fast static front end with commerce APIs for payments and inventory.
Documentation and blogs
Pre-render published articles and documentation, then rebuild or regenerate when content changes.
Modern frameworks
The approach lives on in Next.js static generation and edge-based hosting.

Common questions
What does JAMstack stand for?
It stands for JavaScript, APIs, and Markup. JavaScript handles interaction, APIs provide dynamic data, and Markup is pre-built static content served from a CDN.
Is JAMstack still relevant?
Yes. Pre-rendering and separating content delivery from backend services remain useful approaches. Frameworks such as Next.js can combine static generation with other rendering methods where needed.
What are the benefits of JAMstack?
Cached pages reduce work at the origin and can serve large audiences efficiently. Removing request-time page generation can reduce some server exposure, but APIs, dependencies, credentials and browser code still need security controls.
Is JAMstack good for eCommerce?
It can suit storefront content, with commerce APIs handling carts, checkout and inventory. Prices and stock need an update strategy so cached pages do not mislead shoppers.
Does Udaan build JAMstack or modern front-end sites?
Yes. We build fast, SEO-friendly, and API-driven sites, typically with Next.js and a modern static-generation approach.
When is JAMstack a bad fit?
Avoid it if you need heavy real-time personalization server side or a large amount of constantly changing server-rendered logic on every request.
