Overview

Concrete API client function for fetching all available node component definitions from the Flowise server. This function wraps a parameter-less HTTP GET request to the /nodes endpoint. It is called during canvas initialization to populate the drag-and-drop sidebar and provide the component schema registry used throughout the editor.

Code Reference

Source Location

• File: packages/ui/src/api/nodes.js
• Line: L3

Signature

const getAllNodes = () => client.get('/nodes')

Import

import nodesApi from '@/api/nodes'

The client object is an Axios instance configured in packages/ui/src/api/client.js with a base URL of ${baseURL}/api/v1.

Inputs

Parameter	Type	Required	Description
(none)	--	--	This function takes no parameters

Outputs

Field	Type	Description
data	NodeDefinition[]	Array of all available node component definitions

Each NodeDefinition object contains:

Field	Type	Description
name	string	Unique component identifier (e.g., "chatOpenAI")
label	string	Display name (e.g., "ChatOpenAI")
type	string	Node type classification
icon	string	Icon identifier or SVG path
category	string	Sidebar grouping category (e.g., "Chat Models", "Chains", "Tools")
description	string	Human-readable description of the component
baseClasses	string[]	Output type classes for connection compatibility validation
inputs	InputDef[]	Array of input definitions (parameters and anchors)
outputs	OutputDef[]	Array of output anchor definitions
credential	object or undefined	Optional credential input definition for API key binding
version	number	Component version number for outdated-node detection

Usage Examples

Canvas initialization (as used in the Canvas component)

import nodesApi from '@/api/nodes'
import useApi from '@/hooks/useApi'

const Canvas = () => {
    const getNodesApi = useApi(nodesApi.getAllNodes)

    useEffect(() => {
        // Fetch all node definitions on mount
        getNodesApi.request()
    }, [])

    // Pass fetched node data to the sidebar palette
    return (
        <ReactFlow>
            <AddNodes nodesData={getNodesApi.data} />
        </ReactFlow>
    )
}

Direct async call

import nodesApi from '@/api/nodes'

const response = await nodesApi.getAllNodes()
const nodeDefinitions = response.data
// nodeDefinitions is an array of NodeDefinition objects

Fetching a specific node by name

The nodes.js module also exports a function for fetching individual node definitions:

import nodesApi from '@/api/nodes'

// Fetch a single node definition by component name
const response = await nodesApi.getSpecificNode('chatOpenAI')
const nodeDefinition = response.data

Related API Functions

The nodes.js module exports additional functions:

• getSpecificNode(name) -- Fetches a single node definition by name (L5)
• getNodesByCategory(name) -- Fetches nodes filtered by category (L6)
• executeCustomFunctionNode(body) -- Executes a custom function node (L8)
• executeNodeLoadMethod(name, body) -- Triggers a node's dynamic load method for async options (L10)
