Is there any limit to how much JavaScript the Function node can support within an Edge Workflow?

I’ve been developing an Edge Workflow that uses a Function node that now has 31,000+ characters and I have more implementation to add. What’s the limit?

@Paul_Muschick,

The limit for the node is 64K. However, there is a feature I want to make you aware of.

On the Edge, you have access to [require](https://nodejs.org/api/modules.html#modules_require_id) within the Function Node. So, you can require NPM modules (that are available. see link below) and you can require files.

You can also extend the Edge Agent entirely:
