Documented steps

  1. In any .html file under the project, use %VITE_APP_TITLE% style placeholders, e.g. <h1>Vite is running in %MODE%</h1>.
  2. Any import.meta.env property works, including MODE, BASE_URL, and your VITE_* variables.
  3. They are replaced at transform time by Vite; run npm run dev or vite build to see the substitution.
  4. For complex logic (conditionals) use a custom plugin implementing the transformIndexHtml hook instead of HTML placeholders.
