JAMstack 技术要点

1.  简要说明

Modern web development architecture based on client-side JavaScript, reusable APIs,and 
prebuilt Markup.
When we talk about “The Stack,” we no longer talk about operating systems, specific web
servers, backend  programming languages, or databases.
The JAMstack is not about specific technologies. It’s a new way of building websites and 
apps that delivers better performance, higher security, lower cost of scaling, and a better
developer experience.

2.  3个关键特征

a. JavaScript
         Any dynamic programming during the request/response cycle is handled by
         JavaScript, running entirely on the client. This could be any frontend 
         framework, library, or even vanilla JavaScript.
b.  APIs
         All server-side processes or database actions are abstracted into reusable 
         APIs, accessed over HTTP with JavaScript. These can be custom-built or leverage 
         third-party services.
c.  Markup
         Templated markup should be prebuilt at deploy time, usually using a site 
         generator for content sites, or a build  tool for web apps.

3. 什么不是 jamstack

 a. A site built with a server-side CMS like WordPress, Drupal, Joomla, or Squarespace.
 b. A monolithic server-run web app that relies on Ruby, Node, or another backend language.
 c. A single page app that uses isomorphic rendering to build views on the server at runtime.

 

4. 为什么使用jamstack 

Better Performance
Why wait for pages to build on the fly when you can generate them at deploy time? 
When it comes to minimizing the time to first byte, nothing beats pre-built files
served over a CDN.

Cheaper, Easier Scaling
When your deployment amounts to a stack of files that can be served anywhere, scaling
is a matter of serving those files in more places. CDNs are perfect for this, and often
include scaling in all of their plans.

Higher Security
With server-side processes abstracted into microservice APIs, surface areas for attacks
are reduced. You can also leverage the domain expertise of specialist third-party services.

Better Developer Experience
Loose coupling and separation of controls allow for more targeted development and debugging,
and the expanding selection of CMS options for site generators remove the need to maintain
a separate stack for content and marketing.
