Added support for You.com's Web search & Web contents

[kevmalek]

Summary

Adds two new You.com tool nodes to Flowise, YouDotComSearch and YouDotComWebContents, along with a shared YouDotComApi credential, enabling real-time web search and URL content extraction within Flowise agent flows.

Motivation

You.com's Search API provides structured, AI-optimized web and news results ideal for RAG and agentic workflows. These nodes make it easy for Flowise users to give their agents live web access without writing custom integrations.

Changes

• packages/components/credentials/YouDotComApi.credential.ts — new credential type for You.com API keys
• packages/components/nodes/tools/YouDotComSearch/YouDotComSearch.ts — new tool node wrapping youSearch from @youdotcom-oss/langchain
• packages/components/nodes/tools/YouDotComSearch/Youcom_logo.jpg — node icon
• packages/components/nodes/tools/YouDotComWebContents/YouDotComWebContents.ts — new tool node for URL content extraction
• packages/components/nodes/tools/YouDotComWebContents/Youcom_logo.jpg — node icon
• packages/components/package.json — added @youdotcom-oss/langchain dependency

Implementation Details

• Both nodes use @youdotcom-oss/langchain (youSearch and youContents) which return DynamicStructuredTool instances compatible with any LangChain agent. Langchain.js is no longer accepting new integrations into its monorepo, hence the additional dependency.
• Search and content config (API key, count, freshness, livecrawl, country etc.) are passed at node initialization as defaults; the query / urls inputs are supplied at runtime by the LLM agent

Code Review

This pull request introduces support for You.com's search and web content extraction tools. The changes include new credential and tool nodes, and a new dependency. The implementation is well-structured. I've provided one suggestion to improve the maintainability of the code by simplifying how input parameters are handled.

[gemini-code-assist]

The logic for building the config object can be made more concise and maintainable. Instead of manually handling each input parameter, you can iterate through the this.inputs array. This will automatically handle any future additions or removals of input parameters, reducing the chance of errors.

Suggested change

	const count = nodeData.inputs?.count as number
	const freshness = nodeData.inputs?.freshness as string
	const country = nodeData.inputs?.country as string
	const safesearch = nodeData.inputs?.safesearch as string
	const livecrawl = nodeData.inputs?.livecrawl as string
	const livecrawl_formats = nodeData.inputs?.livecrawl_formats as string
	if (count) config.count = count
	if (freshness) config.freshness = freshness
	if (country) config.country = country
	if (safesearch) config.safesearch = safesearch
	if (livecrawl) config.livecrawl = livecrawl
	if (livecrawl_formats) config.livecrawl_formats = livecrawl_formats
	const inputs = nodeData.inputs ?? {}
	for (const input of this.inputs) {
	if (inputs[input.name]) {
	config[input.name] = inputs[input.name]
	}
