Description

Bumps the Node.js prerequisite in the quick-start install tutorial and the deploy-applications tutorial from Node 16+/18+ to 22.19+, ahead of cdk-terrain#306 (chore(cli)!: replace node-fetch with undici), which raises the cdktn-cli / @cdktn/cli-core engines floor to Node >=22.19.0 (undici 8's requirement).

This is the release this repo's own upgrade-guide-v0-23.mdx already flagged as coming: "Node.js 20.x is end-of-life. Node.js 22.x will become the minimum supported version in an upcoming release."

Changes

  • content/tutorials/install.mdx — Prerequisites: Node.js 16+ and npm 16+Node.js 22.19+ and npm 10+; TypeScript toolchain line Node.js 16.13Node.js 22.19+.
  • content/tutorials/deploy-applications.mdx — Prerequisites: Node.js (v18+) and npm (v8.19+)Node.js (v22.19+) and npm (v10+).

Linked to

  • cdk-terrain#306 — this PR satisfies that PR's "corresponding changes to the documentation" checklist item.

Left out of scope (tracked separately, not needed for #306): a full upgrade-guide-v0-24.mdx entry, since that depends on the actual next cdktn/cdktn-cli version tag once #306 ships in a release.

cdk-terrain#306 (undici migration) raises the cdktn-cli / @cdktn/cli-core
engines floor to Node >=22.19.0, fulfilling the "upcoming breaking
change" flagged in upgrade-guide-v0-23. Update the quick-start and
deploy-applications tutorial prerequisites ahead of that release.
