Svelte-component source file not found: ${sourceFile}

Error message

Svelte-component source file not found: ${sourceFile}

What it means

Thrown by resolveSourceFile when the path passes the absolute and escape guards but the resolved file does not exist on disk. This is the final existence check before the function returns the absolute path to the caller.

Solutions

  1. Verify the file path spelling and that it exists relative to cwd.
  2. If the component is generated by the adapter, ensure the generation step ran before resolveSourceFile is called.
  3. Update the manifest's sourceFile field to the current file location.

Example fix

// before: file does not exist yet
resolveSourceFile('src/lib/Comp.svelte', cwd);

// after: ensure the file exists first
if (!fs.existsSync(path.join(cwd, 'src/lib/Comp.svelte'))) {
  throw new Error('generate the component before resolving');
}
resolveSourceFile('src/lib/Comp.svelte', cwd);
Defensive patterns

Strategy: validation

Validate before calling

import fs from 'node:fs';
import path from 'node:path';
function sourceFileExists(sourceFile, cwd) {
  return fs.existsSync(path.resolve(cwd, sourceFile));
}

Type guard

function isExistingSource(sourceFile, cwd) {
  return typeof sourceFile === 'string' && !path.isAbsolute(sourceFile) && fs.existsSync(path.resolve(cwd, sourceFile));
}

Try / catch

try {
  resolveSourceFile(sourceFile, cwd);
} catch (err) {
  if (err.message.startsWith('Svelte-component source file not found')) {
    await generateComponent(sourceFile);
    resolveSourceFile(sourceFile, cwd);
  } else throw err;
}

Prevention

When it happens

Trigger: Calling resolveSourceFile('src/lib/Missing.svelte', cwd) where the file has not been created yet, was deleted, or is misspelled.

Common situations: Component not yet generated, a typo in the manifest sourceFile field, or a stale manifest pointing at a renamed/removed file.
