`$env/static/public` is deprecated, use `$app/env/public` in

Error message

`$env/static/public` is deprecated, use `$app/env/public` instead

What it means

In development mode, importing from the deprecated `$env/static/public` module triggers a console warning. SvelteKit renamed/relocated the environment variable modules and keeps `$env/static/public` as a re-export shim of `$app/env/public` for backwards compatibility. The warning tells you to update imports before the alias is removed in a future major release.

Solutions

Replace the import with `import ... from '$app/env/public'` in the offending file(s).
Search the repo for `$env/static/public` and update all occurrences (including in libraries you control).
Pin/update dependencies that internally import `$env/static/public` to versions using the new module path.

Example fix

// before
import { PUBLIC_API_URL } from '$env/static/public';
// after
import { PUBLIC_API_URL } from '$app/env/public';

Defensive patterns

Strategy: validation

Validate before calling

// grep-style preflight check (e.g. in a lint script)
const offenders = await glob('src/**/*.{js,ts,svelte}')
  .filter((f) => read(f).includes('$env/static/public'));
if (offenders.length) throw new Error('Update to $app/env/public: ' + offenders.join(', '));

Prevention

Use the new `$app/env/public` module path in all new code.
Add a lint rule or grep CI step banning `$env/static/public`.
Check dependency changelogs when upgrading SvelteKit for renamed module paths.

When it happens

Trigger: Any dev-mode import of `$env/static/public` (e.g. `import { PUBLIC_API_URL } from '$env/static/public'`) executed in a module that is loaded while DEV is true; the shim re-exports and then warns.

Common situations: Upgrading an older SvelteKit project whose code or dependencies still reference the legacy `$env/static/*` paths; copy-pasted tutorials predating the module reorganization.
