Vite Plugin Breaks Debugging #322

The vite plugin breaks debugging as it appears babel is forcing sourceMaps to not generate and breaking everything in dev. As a proof of concept I hard edited ./node_modules/@suid/vite-plugin/index.mjs in my project to replace the transform method with this:

function transform(code, options, id) {
  const ast = parse(code, options.parserOptions);
  traverse(ast, {
    enter(path) {
      const { node } = path;
      const optimize = types.isImportDeclaration(node) && options.optimizeImports.paths.some((v) => v === node.source.value);
      if (!optimize) return;
      const imports = node.specifiers.map((spec) => {
        if (types.isImportSpecifier(spec) && types.isIdentifier(spec.imported) && types.isIdentifier(spec.local)) {
          return getOptimizedImportPath(
            node.source.value,
            spec.imported.name,
            spec.local.name
          );
        }
      }).filter((v) => !!v);
      path.replaceWithMultiple(
        imports.map(
          (item) => types.importDeclaration(
            typeof item.specifier === "string" ? [types.importDefaultSpecifier(types.identifier(item.specifier))] : [
              ...Object.entries(item.specifier).map(
                ([alias, specifier]) => types.importSpecifier(
                  types.identifier(specifier),
                  types.identifier(alias)
                )
              )
            ],
            types.stringLiteral(item.path)
          )
        )
      );
    }
  });
  return generate(ast, {
	sourceMaps: true,
	sourceFileName: id
  });
}

The changes being to add id to the transform method's parameters for later and then passing the id to sourceFileName to the generate call at the end along with sourceMaps: true

and then updated the call to transform in the suidPlugin return:

  return {
    // everything else
    transform(code, id) {
      const transformIconImportsOptions = options.optimizeImports || {};
      if (transformIconImportsOptions.enabled && transformIconImportsOptions.paths?.some((p) => code.includes(p))) {
        return transform(code, options, id);
      }
    }
  };

and just like that my step debugging was fixed.
