There’s no doubt that front-end development will be one of the hottest disciplines in tech in 2020

2. Static Site Generators

Static site generators combine both the power of server-side rendering (very important for SEO but also initial load time) and single-page applications.
Many projects these days choose a SSG even if they don’t need server-side rendering because solutions like Next or Nuxt come with handy features, such as markdown support, module bundlers, integrated test runners, etc.
If you’re serious about front-end development, you should take a close look into the following projects, and try to get some hands-on experience on them:

• 
  Next (React-based)
  
• 
  Nuxt (Vue-based)
  
• 
  Gatsby (React-based)
  
• 
  Gridsome (Vue-based)
  

These will probably be the hottest ones in 2020, though there are more out there. Check out these resources if you want to learn more about them:

• 
  Next.js
  
• 
  Nuxt.js
  
• 
  Gatsby
  
• 
  Gridsome
  

3. JAMstack

The term JAMstack stands for JavaScript (running on the client — for example, React, Vue, or VanillaJS), API (server-side processes are abstracted and accessed over HTTPS via JavaScript), and markup (templated markup that’s prebuilt at deploy time).
It’s a way of building websites and apps for better performance — lower scaling costs, providing higher security, and offering a better developer experience.
While these terms are nothing new on their own, they all have the same thing in common — they don’t depend on a web server. So a monolithic app that relies on a Ruby or Node.js back end or a site built with a server-side CMS like Drupal or WordPress isn’t built with the JAMstack.
There are some best practices if you want to work with the JAMstack:
