Example Usage:

import ReportService from "jasper_nodejs";

const reportService = new ReportService();

const outputDir = app.makePath("tmp/reports"); // specify the directory where the generated report files will be saved (app.makepath is adonisjs)

const fileName = `${cuid()}`;
const formatType = "pdf";
// output filename
const pdfPath = path.join(outputDir, fileName);

// Ensure the directory exists
if (!fs.existsSync(outputDir)) fs.mkdirSync(outputDir, { recursive: true });

try {
  const outputFile = await reportService
    .export({
      // you may use the .jrxml extension; the .jasper file is generated by compiling the .jrxml template
      reportFile: app.makePath("resources/reports/jadwal.jasper"),
      // If you want to use a custom output filename, do NOT pass the path of the
      // directory you created.
      // Instead, append an additional path segment.
      // The last path segment (which does NOT exist as a directory)
      // will be treated by Jasper as the output filename.
      outputDir: pdfPath,
      // e.g view, print, pdf, rtf,  xls,  xlsMeta, xlsx, docx, odt, ods, pptx,  csv,  csvMeta,  html, xhtml, xml, jrprint
      format: "pdf",
      // Parameters defined here will be forwarded to Jasper reports and can be accessed using $P{idproduct}. if you need jsonb parameter you can use like this
      params: {
        idproduct: 3,
        details: {
          price: 5000,
          expired: "2025-12-31",
        },
      },
      db: {
        // e.g. postgres
        dbname: "your_database_name",
        // e.g. localhost
        host: "your_database_host",
        // e.g postgres, mysql
        driver: "postgres",
        // e.g default PostgreSQL port 5433
        port: "your_database_port",
        // e.g. postgres
        username: "your_database_user",
        // e.g. akd1QDF
        password: "your_database_password",
      },
    })
    .run();

  // The run() method can be replaced with command().
  // If you use command(), it will return the generated CLI command
  // and store it in the outputFile variable instead of executing it.
  // You can then copy and paste the command into the terminal
  // to debug or generate the PDF manually.
} catch (error) {
  console.log(error);
