How to create an exhaust script

The IF framework outputs data in yaml format. Any other output formats require a separate script that takes the yaml output data and processes it. We provide if-csv for outputting data in csv format bundled with IF. For any other format, you need to write an exhaust script. This guide will help you create your own exhaust script.

In this example, we'll create a script that executes the manifest and outputs the data in json format.

const IfJson = async () => {
  const { manifest, output, params } = await parseIfCsvArgs();

  if (manifest) {
    const manifestData = await getManifestData(manifest!);
    const options: CsvOptions = {
      tree: manifestData.tree,
      context: manifestData,
      outputPath: output,
      params,
    };
    const result = await generateCsv(options);

    if (!output && result) {
      console.log(result);
    }
  }

  process.exit(0);
};

IfJson().catch(handleError);

To add this script to your package.json, include the following entry in the scripts section:

"scripts": {
  "if-json": "npx ts-node if-json.ts"
}

This setup ensures that your script will execute the manifest and output the data in JSON format.
