GitBook V2

This package contains the code for an experiment new version of the GitBook renderer.

The goals of this new version are:

• Optimize rendering to leverage Next.js ISR and static rendering
• Leverage Node.js runtime and bigger instances to render bigger content
• Evaluate Vercel and Cloudflare deployment options

Deployment

Vercel

The new version is deployed automatically to Vercel using a Github Action on every push.

Cloudflare with Opennext-js

The new version is deployed automatically to Cloudflare using a Github Action on every push.

Potential issues

• We can't use dynamicIO because our root layout needs to fetch the params (vercel/next.js#71927)
• How to do nonce for static resources when we can't use headers() (dynamic API) (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy)

Structure

Middleware:

Goals:

• Route between dynamic and static routes
  • If a token is in the cookies => dynamic route
  • If a token is in the url => dynamic route
  • Else => static route
• High performances:
  • It should not rely on data fetching

URLs to support:

Content URLs:

• docs.company.com/page
  • Middleware: rewrite to /static/url/docs.company.com/page
  • Page component renders the page
• docs.company2.com/section/page
  • Middleware: rewrite to /static/url/docs.company2.com/section/page
  • Page component renders the page
• docs.company3.com/section/sitespace/page
  • Middleware: rewrite to /static/url/docs.company3.com/section/sitespace/page
  • Page component renders the page

Content URLs (adaptive content or visitor authentication):

• docs.company.com/page
  • Middleware:
    • If a token is in the cookies or url => dynamic route
    • Else => rewrite to /dynamic/url/docs.company.com/page
  • Page component renders the page
    • Read the token from the url query params or cookies

PDF export URLs:

• docs.company.com/page/~gitbook/pdf
  • Middleware: rewrite to /dynamic/pdf/docs.company.com/page
  • Page component renders the page

Images resizing:

• docs.company.com/~gitbook/image
  • Middleware: rewrite to /dynamic/image/docs.company.com
  • Route handlers process the request

Preview URLs:

• open.gitbook.com/sites/site_abc/page (or open.gitbook.com/~site/site_abc/page to stay compatible?)
  • Middleware: no rewrite
  • Page component renders the page (dynamic?)
    • Read the token from the url query params
    • Read customizations override from the url query params

Space PDF URLs:

• open.gitbook.com/spaces/space_abc/pdf
  • Middleware: no rewrite
  • Page component renders the page (dynamic?)
    • Read the token from the url query params
    • Read customizations override from the url query params

Development:

• localhost:3000/sites/site_abc/page

Routes:

• Content
  • /static/url/[[...url]]/page.tsx
  • /dynamic/url/[[...url]]/page.tsx
• Images resizing
  • /dynamic/image/[hostname]/route.ts
• PDF export
  • /dynamic/pdf/[[...url]]/page.tsx
  • /spaces/[space]/pdf/page.tsx
