If you define scripts to be run in your package.json you will find that Windows will choke if you rely on a Node.js shebang. Let’s say you have the following executable script npm-postinstall in the bin folder of your project. This will also normalize the result for you. If you need to join paths together use path.join. var filePath = path.normalize('/home/george/./folder/code') Īs we saw before with the string concatenation example kittens can die if you use string concatenation. This will present you with the correct path on whatever platform you are using. If you find yourself doing things like this var filePath = '/home/george/./folder/code' Use path.normalize to create reliable paths

Using path.resolve lets you move around the file system but maintain cross platform compatibility. Use path.resolve to traverse the filesystem The path module gives you all of the tools you need to handle cross-platform paths. Whilst forward slashes will work ok on Windows if you do string concatenation you miss out on the protection that the path module in Node.js gives you.
