1. What is Static Site Generation (SSG)?

Static Site Generation, aka Static Rendering (SR), is the process of delivering a pre-rendered, or static, HTML to the client that was built ahead of time instead of in response to a request.

2. How does Static Site Generation (SSG) work?

How does Static Site Generation (SSG) work?
  1. we start with the server, which fetches any needed data from external datastores
  2. combines the data with HTML templates, to generate a static HTML page for each route
  3. when a client sends a GET request
  4. the server responds with a pre-generated HTML page
  5. which the client then renders

3. What are the Pros and Cons of Static Site Generation (SSG)?


  • fast load
  • cheap to host and cache
  • server load scales with content change, not user requests
  • secure
  • easy distribution via CDNs


  • every content change requires entire site be rebuilt
  • limited user management
  • real-time data needs to be added separately
  • same content for all users

4. When should you use Static Site Generation (SSG)?

  • when you need fast load times
  • when your content is mostly the same for all users
  • when your content does not change very often

Perfect for static content websites, such as blogs, magazines, projects and maybe also e-commerce websites
