how to remove empty line using jscodeshift?

[sibelius]

I want to transform this

const obj = {
  a: 'a',

  b: 'b',

  c: 'c',
  d: 'd',
}

into this

const obj = {
  a: 'a',
  b: 'b',
  c: 'c',
  d: 'd',
}

this is my first approach

import type { API, FileInfo, Options } from 'jscodeshift';

import { getPrintOptions } from '../getPrintOptions';

function transform(file: FileInfo, api: API, options: Options) {
  const j = api.jscodeshift; // alias the jscodeshift API

  const root = j(file.source); // parse JS code into an AST

  const printOptions = getPrintOptions(options);

  let linesToRemove = [];

  root
    .find(j.ObjectExpression)
    .forEach((path) => {
      // Find properties in the object
      const properties = path.node.properties;

      // // Sort properties by their starting line number
      const sortedProperties = properties.sort((a, b) => a.loc.start.line - b.loc.start.line);

      // Remove any blank lines between properties
      for (let i = 0; i < sortedProperties.length - 1; i++) {
        const endLine = sortedProperties[i].loc.end.line;
        const nextStartLine = sortedProperties[i + 1].loc.start.line;

        // Remove empty lines between properties
        if (nextStartLine - endLine >= 1) {
          for (let line = endLine + 1; line < nextStartLine; line++) {
            linesToRemove = [
              ...linesToRemove,
              line,
            ];

            console.log({
              line,
            });
          }
        }
      }

      return path.node;
    });

  // linesToRemove.sort((a, b) => b - a).map((line) => {
  //   root.find(j.Literal).at(line).remove();
    // root.find(j.Identifier).at(line).remove();

    // root.find(j.Literal, { loc: { start: { line } } }).remove();
  // });

  return root.toSource(printOptions);
}

module.exports = transform;
module.exports.parser = 'tsx';

I believe that anything involving spacing is going to be taking place at the recast layer as opposed to the jscodeshift layer, so it's kind of out of our hands.

You'd probably get the most mileage out of creating lint/prettier rules for your codebase and running the transformed code through that, which is what I understand what Meta does when they use jscodeshift.
