Babel Class Field Parsing

Configure Babel so class field syntax is accepted both via configuration files and inline programmatic transforms.

Capabilities

Parses class fields from config-driven transforms

• parseWithConfig reads a Babel config file at a provided path and transforms a source file that includes public fields, static fields, private fields, and private methods without throwing. The returned code string still contains those class field declarations. @test

Parses class fields from inline transforms

• transformSnippetInline transforms a provided snippet string containing public, static, and private class elements using programmatic Babel options without relying on external config files. The returned code string still contains the inline class field declarations. @test

Leaves syntax untouched

• Neither transform strips or rewrites class field declarations; outputs mirror the original class bodies aside from formatter differences. @test

 * Returns the generated code string, ensuring class field syntax is accepted.
 */
export function transformSnippetInline(snippet);
