bail

Error handling in asynchronous functions

This feature demonstrates how `bail` can be used in asynchronous functions to handle errors. If an error occurs during the `someAsyncOperation` call, `bail` is called with the error, effectively throwing the error and allowing it to be caught by higher-level error handlers or causing the process to exit if uncaught.

const bail = require('bail');

async function fetchData() {
  try {
    const data = await someAsyncOperation();
    return data;
  } catch (err) {
    bail(err);
  }
}

fetchData();

Error handling in synchronous functions

This feature shows how `bail` can be used in synchronous functions to handle errors. If an error occurs while reading or parsing the config file, `bail` is invoked with the error, which then either gets caught by a higher-level error handler or causes the process to exit if it remains uncaught.

const bail = require('bail');

function readConfigFile() {
  try {
    const config = fs.readFileSync('/path/to/config.json', 'utf8');
    return JSON.parse(config);
  } catch (err) {
    bail(err);
  }
}

readConfigFile();
