Checks if the given TypeScript code has valid syntax.

This function attempts to parse the code using SWC’s TypeScript parser without performing any macro expansion.

Arguments

• code - The TypeScript source code to check
• filepath - The file path (used to determine if it’s TSX based on extension)

Returns

A SyntaxCheckResult indicating success or containing the parse error.

Example

const result = check_syntax("const x: number = 42;", "test.ts");
if (!result.ok) {
    console.error("Syntax error:", result.error);
}
