03:34 - Server-rendered

  • Both do server rendered
  • Gatsby is gone at build time
  • Next is done at build and on deploy

05:26 - Static generation

  • getStaticProps()
  • getServerSideProps()

08:25 - Re-rendering pages

  • Gatsby can be re-rendered and re-deployed - any CMS lets you do this on only the pages that changed.
  • Gatsby-cloud
  • Next.js has the revalidate flag that will re-render when stale

18:54 - Data management

  • Gatsby has a built in GraphQL API feature with
  • Next.js has nothing - it’s not their problem. Use Apollo, or SWR, React Query, or redux, or whatever you want.

23:16 - Client-side data

  • Neither do anything, next.

26:33 - Dynamic Pages

  • List of 100 shoes, each one gets a page
  • List of four types of shoes: basketball, runners, casual, bowling, etc.
  • List of 10 colors: each color gets its own page.
  • List of 12 sizes, each size gets its own page.
  • Now it gets complicated when you do this:

    • What about size 6+7?

  • Gatsby will get “Hosted GraphQL”: https://twitter.com/kylemathews/status/1252803849775009794

  • Anywhere

35:54 - Images

  • Compression/resize
  • Lazy loading
  • SVG
  • Blur up
  • Next 10 released first revision of Next.js image
    • It’s not as good as Gatbsy-image
    • Must specify width and height, whereas gatsby has fixed and fluid
    • Compression
    • No blur up
    • Yes lazy loading
    • both don’t support gifs
    • Gatbsy requires annoying GraphQL query OR another plugin like MDX to do it
