NodeJS: How do I pass arguments to a function using process.nextTick

Question

I'm trying to make a web crawler to fetch products from certain sites to reduce my memory usage (I've got a memory leak somewhere i haven't found). So I'm trying to send arguments to a callback asynchronously in order to terminate the current context.

This is where I'm at:

var big = html.get(url);
callback(big);
big = null; // this isn't going to get erased until after big is done is it?

This is what I've tried:

var big = html.get(url);
process.nextTick(function() {callback(big)}); // this seems wrong to me.
big = null;

Answer 1

process.nextTick() doesn't support passing arguments like setTimeout() does. You will just need to make a function that passes the arguments.

So instead of:

setTimeout(myfunc, 0, 'arg1', 'arg2')

Use this:

process.nextTick(function() { myfunc('arg1', 'arg2') })

You can also use a function to build your function.

Finally, setTimeout doesn't support specifying the object that the function gets called on, so it's limited in its usefulness.
