How to use the eslint-config-fbjs.rules function in eslint-config-fbjs

// Can't be ESModules as this is not compiled
const fbjsConfig = require('eslint-config-fbjs');

const variableNamePattern = String.raw`\s*[a-zA-Z_$][a-zA-Z_$\d]*\s*`;
const importPattern =
  String.raw`^(?:var|let|const|import type)\s+` +
  '{?' +
  variableNamePattern +
  '(?:,' +
  variableNamePattern +
  ')*}?' +
  String.raw`\s*(?:=\s*require\(|from)[a-zA-Z_+./''\s\d\-]+\)?[^;\n]*[;\n]`;
const maxLenIgnorePattern = String.raw`(^\s*(it|test)\(|${importPattern})`;

delete fbjsConfig.rules['babel/flow-object-type'];

module.exports = Object.assign({}, fbjsConfig, {
