• Understand the issue: Need to improve error messages with file, line, source code, and stack trace
• Analyze current implementation in script.rs and lib.rs
• Identify V8 Message API available through TryCatch
• Create helper function to format errors with V8 Message API
• Update script.rs to use V8 Message for better error formatting
• Update module.rs error handling for compilation errors
• Update lib.rs error handling in import and run_script
• Test with syntax errors to verify file/line/source display
• Test with runtime errors to verify stack trace display
• Update test expectations in test_api.rs
• Run all tests to ensure no regressions
• Fix formatting and clippy warnings
• Fix code formatting issue in lib.rs that was causing CI to fail

Changes Made

Enhanced Error Formatting

• Added format_exception() function in error.rs that extracts detailed information from V8's Message API
• Error messages now include:
  • File path and line number (e.g., /tmp/test_error.js:2)
  • Source code line with the error
  • Caret indicator (^^^) pointing to the error location
  • Original error message
  • Full stack trace for runtime errors

Updated Error Handling

• script.rs: Modified to return formatted error strings instead of V8 values
• module.rs: Enhanced resolve() to catch and format compilation errors
• lib.rs: Updated import() to properly handle and format both compilation and runtime errors

Test Updates

• Updated test_api.rs expectations to match new error format
• All existing tests pass with the new error format

Build Fix

• Fixed code formatting in lib.rs to comply with rustfmt requirements

Example Output

Syntax Error:

/tmp/test_error.js:2
results['dynamic import'] = typeof import === 'function';
                                          ^^^

SyntaxError: Unexpected token '==='

Runtime Error with Stack Trace:

Error: Something went wrong
    at baz (/tmp/test_stack.js:10:11)
    at bar (/tmp/test_stack.js:6:5)
    at foo (/tmp/test_stack.js:2:5)
    at /tmp/test_stack.js:13:1
