Question on "require" about art-of-node HOT 3 CLOSED

@yolapop Hi, thanks for the great question.

Isn't it needed to add ./ in require to find local modules?

Yes, you are absolutely correct here. Now that you point that out, I think I should probably update that section as it is currently inaccurate.

Node.js will perform a hierarchical directory search for "node_modules" and "utils" in the following ways:

./node_modules/utils.js
./node_modules/utils/index.js
./node_modules/utils/package.json

I don't think this is technically accurate either... the directory search would look like this instead:

• node would check for existence of ./node_modules/utils/package.json
• if it does not exist, it will try ../node_modules/utils/package.json
• if that does not exist, it will try .../node_modules/utils/package.json etc until it reaches /
• when it finds some folder called utils with a package.json in it inside of a node_modules it will read the package.json and check and see if a main property is set. for example, you could set your main to be called utils.js. otherwise if main is not specified it will default to looking for index.js
• finally, now that it knows the folder of the utils module and the name of the main entry file, it will require the main entry file

hope this helps!
