How to use the @codemod/parser.parse function in @codemod/parser

export default function js(code: string): t.File {
  return stripExtras(parse(code));
}

export function program(
  template: string
): (replacements?: R) => t.File {
  const ast = parse(template);

  return (replacements = {} as R) => {
    const unusedReplacements = new Set(Object.keys(replacements));

    traverse(ast, {
      Placeholder(path: NodePath): void {
        const name = path.node.name.name;
        const replacement = replacements[name];

        if (!replacement) {
          throw new Error(
            `no replacement found for placeholder with name: ${name}`
          );
        }

        if (Array.isArray(replacement)) {

static run(content: string): StageResult {
    const log = logger(this.name);
    log(content);

    const editor = new MagicString(content);
    const ast = parse(content, {
      tokens: true
    });

    const { insertions, removals } = asi(content, ast);

    insertions.forEach(({ index, content }) => editor.appendLeft(index, content));
    removals.forEach(({ start, end }) => editor.remove(start, end));

    return {
      code: editor.toString(),
      suggestions: []
    };
  }
}
