(
  • type
)
Class

Returns:

Class:

the node class

getNodeType

(
  • category
)
Array

Defined in ../src/litegraph.js:239

Returns a list of node types matching one category

Parameters:

  • category String

    category name

Returns:

Array:

array with all the node classes

getNodeTypesCategories

() Array

Defined in ../src/litegraph.js:261

Returns a list with all the node type categories

Returns:

Array:

array with all the names of the categories

registerNodeType

(
  • type
  • base_class
)

Defined in ../src/litegraph.js:70

Register a node class so it can be listed when the user wants to create a new one

wrapFunctionAsNode

(
  • name
  • func
  • param_types
  • return_type
)

Defined in ../src/litegraph.js:135

Create a new node type by passing a function, it wraps it with a propper class and generates inputs according to the parameters of the function. Useful to wrap simple methods that do not require properties, and that only process some input to generate an output.

Parameters:

  • name String

    node name with namespace (p.e.: 'math/sum')

  • func Function
  • param_types Array

    [optional] an array containing the type of every parameter, otherwise parameters will accept any type

  • return_type String

    [optional] string with the return type, otherwise it will be generic
