Node Cookbook - Third Edition

How it works...

Both fs and path are core modules, so there's no need to install these dependencies.

The path.join method is a useful utility that normalizes paths across platforms, since Windows uses back slashes (\) whilst others use forward slashes (/) to denote path segments.

We use this three times, all with the cwd reference which we obtain by calling process.cwd() to fetch the current working directory.

The fs.readFileSync method will synchronously read the entire file into the process memory.

This means that any queued logic is blocked until the entire file is read, thus ruining any capacity for concurrent operations (such as serving web requests).

That's why synchronous operations are usually explicit in Node Core (for instance, ...
