Error handling

[iczn]

When using the fs reading mechanism with pipes, an error is thrown in strict mode if one of the rows does not match the length of the header. However, a try-catch block around the entire chain won't catch the error. Here's an example:

try {
    fs.createReadStream(file_path)
    .pipe(csv({
        separator: ",",
        strict: true
    }))
    .on('headers', function (headers) {
        console.log("headers: ", headers)
    })
    .on('data', function (data) {
        // a row was parsed
        results.push(data)
    })
    .on('end', function () {
        //
        console.log(results);
    });
} catch (err) {
    // error parsing csv - it never gets here
}

The issues here aren't for support. Please read about error handling with streams, which is what you're using when you pipe.
