The example does not have heavy use of typescript. so there are only a few occurrences you need to check.

  • remove typescript specific packages: npm uninstall typescript @types/node @types/react
  • remove typescript configuration and types folder: rm -rf types tsconfig.json
  • rename index page: mv pages/index.tsx pages/index.jsx
    • then remove :InferGetServerSidePropsType<typeof getServerSideProps> from Home component function.
  • rename db file: mv lib/mongodb.ts lib/mongodb.js
    • then remove :Promise<MongoClient> from clientPromise decleration

an alternative is to crawl old examples in old versions in the github repository and use that link as the example.

this following will install example in next-11 from a year ago:

npx create-next-app --example https://github.com/vercel/next.js/tree/next-11/examples/with-mongodb nextmongo

This got me the example code, but failed to install dependencies due to version changes to React. You will need to fix those dependencies by yourself.

PS: even though the size is small, this will be a bit slower to read files from GitHub.
