From 16ce5217f588870ecb731f8480ac0312e7474007 Mon Sep 17 00:00:00 2001 From: Thibault Jaigu Date: Mon, 13 Jul 2026 10:08:30 +0100 Subject: [PATCH] feat(components): add Requesty chat model node Add a Requesty chat model node mirroring the existing OpenRouter node. Requesty is an OpenAI-compatible LLM gateway, so the node reuses the LangChain ChatOpenAI wrapper with a fixed base URL of https://router.requesty.ai/v1 and a dedicated requestyApi credential. - packages/components/nodes/chatmodels/ChatRequesty/ChatRequesty.ts - packages/components/nodes/chatmodels/ChatRequesty/FlowiseChatRequesty.ts - packages/components/nodes/chatmodels/ChatRequesty/requesty.svg - packages/components/credentials/RequestyApi.credential.ts Signed-off-by: Thibault Jaigu --- .../credentials/RequestyApi.credential.ts | 25 +++ .../chatmodels/ChatRequesty/ChatRequesty.ts | 194 ++++++++++++++++++ .../ChatRequesty/FlowiseChatRequesty.ts | 20 ++ .../chatmodels/ChatRequesty/requesty.svg | 1 + 4 files changed, 240 insertions(+) create mode 100644 packages/components/credentials/RequestyApi.credential.ts create mode 100644 packages/components/nodes/chatmodels/ChatRequesty/ChatRequesty.ts create mode 100644 packages/components/nodes/chatmodels/ChatRequesty/FlowiseChatRequesty.ts create mode 100644 packages/components/nodes/chatmodels/ChatRequesty/requesty.svg diff --git a/packages/components/credentials/RequestyApi.credential.ts b/packages/components/credentials/RequestyApi.credential.ts new file mode 100644 index 00000000000..32669a5aa07 --- /dev/null +++ b/packages/components/credentials/RequestyApi.credential.ts @@ -0,0 +1,25 @@ +import { INodeParams, INodeCredential } from '../src/Interface' + +class RequestyAPIAuth implements INodeCredential { + label: string + name: string + version: number + description: string + inputs: INodeParams[] + + constructor() { + this.label = 'Requesty API Key' + this.name = 'requestyApi' + this.version = 1.0 + this.inputs = [ + { + label: 'Requesty API Key', + name: 'requestyApiKey', + type: 'password', + description: 'API Key' + } + ] + } +} + +module.exports = { credClass: RequestyAPIAuth } diff --git a/packages/components/nodes/chatmodels/ChatRequesty/ChatRequesty.ts b/packages/components/nodes/chatmodels/ChatRequesty/ChatRequesty.ts new file mode 100644 index 00000000000..760d4c872c9 --- /dev/null +++ b/packages/components/nodes/chatmodels/ChatRequesty/ChatRequesty.ts @@ -0,0 +1,194 @@ +import { ChatOpenAI as LangchainChatOpenAI, ChatOpenAIFields } from '@langchain/openai' +import { BaseCache } from '@langchain/core/caches' +import { ICommonObject, IMultiModalOption, INode, INodeData, INodeParams } from '../../../src/Interface' +import { getBaseClasses, getCredentialData, getCredentialParam } from '../../../src/utils' +import { ChatRequesty } from './FlowiseChatRequesty' + +class ChatRequesty_ChatModels implements INode { + label: string + name: string + version: number + type: string + icon: string + category: string + description: string + baseClasses: string[] + credential: INodeParams + inputs: INodeParams[] + + constructor() { + this.label = 'Requesty' + this.name = 'chatRequesty' + this.version = 1.0 + this.type = 'ChatRequesty' + this.icon = 'requesty.svg' + this.category = 'Chat Models' + this.description = 'Wrapper around Requesty Inference API' + this.baseClasses = [this.type, ...getBaseClasses(LangchainChatOpenAI)] + this.credential = { + label: 'Connect Credential', + name: 'credential', + type: 'credential', + credentialNames: ['requestyApi'], + optional: true + } + this.inputs = [ + { + label: 'Cache', + name: 'cache', + type: 'BaseCache', + optional: true + }, + { + label: 'Model Name', + name: 'modelName', + type: 'string', + placeholder: 'openai/gpt-4o-mini' + }, + { + label: 'Temperature', + name: 'temperature', + type: 'number', + step: 0.1, + default: 0.9, + optional: true + }, + { + label: 'Streaming', + name: 'streaming', + type: 'boolean', + default: true, + optional: true, + additionalParams: true + }, + { + label: 'Allow Image Uploads', + name: 'allowImageUploads', + type: 'boolean', + description: + 'Allow image input.
