Vite Checker Setup

Install and configure two complementary systems so all errors appear in the terminal during development:

• vite-plugin-checker — TypeScript compile-time errors (types, syntax).
• server.forwardConsole — Browser runtime errors (console.*, unhandled errors) via Vite 8 native support.

When to use

• Setting up a new Vite + TypeScript project
• User wants TS errors in terminal during dev
• User complains about not seeing type errors until build
• User wants browser console output (runtime errors, logs) in the terminal
• Adding dev-time error reporting to an existing Vite project

Pre-flight checks
