Implementation Notes

  • The ZIP file is streamed directly to the response using Archiver with maximum compression (level 9)
  • Each employee’s documents are generated in parallel using Puppeteer
  • If an individual employee’s contract generation fails, the error is logged but the process continues for other employees
  • The filename uses the current date in DD-MM-YYYY format
  • Folder names in the ZIP are lowercase and spaces are removed from contract types
  • File paths follow the pattern: {contractType}/{filename} for contracts and {contractType}/Tratamiento de datos/{dni}.pdf for data processing documents
  • Preview Contract - Preview a single employee contract before generating a batch
