StartSanityChecks();

AddSanityCheck("memory", () => {
  const formatMemoryUsage = (data) =>
    `${Math.round((data / 1024 / 1024) * 100) / 100}`;

  const memoryUsage = process.memoryUsage();

  // Check if memory usage is over 100MB
  if (parseFloat(formatMemoryUsage(memoryUsage.heapUsed)) > 100) {
    return [
      false,
      `Exceeded memory limit. Current usage: ${formatMemoryUsage(
        memoryUsage.heapUsed
      )}MB`,
    ];
  }

  return [true, null];
