ComfyDeploy: How SRL's nodes works in ComfyUI?

What is SRL's nodes?

Nodes: SRL Conditional Interrupt, SRL Format String, SRL Eval, SRL Filter Image List. This is a collection of nodes I find useful. Note that at least one module allows execution of arbitrary code. Do not use any of these nodes on a system that allow untrusted users to control workflows or inputs.[w/WARNING: The custom nodes in this extension are vulnerable to **security risks** because they allow the execution of arbitrary code through the workflow]

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for SRL's nodes and select it
  5. Close the build step dialig and then click on the "Save" button to rebuild the machine

SRL's nodes

This is a collection of nodes I find useful. Note that at least one module allows execution of arbitrary code. Do not use any of these nodes on a system that allow untrusted users to control workflows or inputs.

Nodes

SRL Conditional Interrupt

Screenshot of SrlConditionalInterrupt

Interrupts the currently running prompt if the "interrupt" input is true. Also passes through an item of any type for sequencing purposes.

SRL Format String

Screenshot of SrlFormatString

Format a string using Python's string format syntax. You can use both positional and named argument syntax.

SRL Eval

Screenshot of SrlEval

Evaluate arbitrary Python code as a function. Do not use on a system accessible by untrusted users. Code is evaluated as:

def func({parameters}):
    code\_line1
    code\_line2
    ...

Right now this uses the globals dictionary from the module, so be careful about anything that might mutate globals, such as importing modules. I don't have any intention to try to make it secure because ComfyUI itself isn't remotely secure, but I will probably try to improve isolation at some point in the future to prevent unintended problems. PRs gladly accepted if you have need for this.

SRL Filter Image List

Screenshot of SrlFilterImageList

Takes a list of images and a list of bools as input and outputs a list of the input images where the bool is true.
