How can I implement error handling with logging in my application?

You can implement error handling by using try-catch blocks in your code. Logging can be done using libraries like Log4j or Winston.

What are the best practices for logging errors?

Best practices include logging at different levels (info, warning, error), including timestamps, and avoiding sensitive data.

Can you show me a code example?

Sure! Here's a simple example in JavaScript:

try {
    // code that may throw an error
} catch (error) {
    console.error('Error occurred:', error);
    // log the error to a file or monitoring system
}

How do I log errors to a file?

You can use the 'fs' module in Node.js to write errors to a file. Here's an example:

const fs = require('fs');

fs.appendFile('error.log', error + '\n', (err) => {
    if (err) throw err;
});
