Building a Chatbot with Chakra UI + LangChain + Ollama Cloud
A full tutorial to design a Chakra UI chat experience and power it with LangChain and Ollama Cloud gpt-oss:120b-cloud.
Building a Chatbot with Chakra UI + LangChain + Ollama Cloud (Hono + React) You asked for a real build, not a toy. So we are going to wire a proper backend with **Hono**, a clean **React + Chakra UI** frontend, and connect everything to **LangChain + Ollama Cloud** using . This is a full stack walkthrough with actual structure, guardrails, and sensible engineering decisions. This version focuses on: A minimal, production-minded backend A responsive, readable chat UI React best practices: small components, clear state transitions, stable callbacks Practical defaults: history trimming, error handling, and safe prompts Architecture (Short and Clear) Frontend (React + Chakra UI)** Renders messages Collects user input Calls Backend (Hono)** Validates requests Builds the model prompt Calls LangChain ChatOllama Returns structured JSON Model (Ollama Cloud)** runs through local Ollama with cloud offload Step 1: Prepare Ollama Cloud Sign in once, then run the cloud model locally. Ollama will handle auth automatically after sign‑in. If you prefer using the cloud API directly, create an API key and set . Ollama will use it when you call . Step 2: Backend Server with Hono (Node) We will run a tiny Node server with Hono. This gives you a clean API surface and future‑proofs your app for streaming, logging, and analytics. Install server dependencies Server: Why this is solid Schema validation** keeps your API safe. History trimming** keeps tokens under control. System prompt** makes the assistant predictable. Hono’s Node adapter** keeps the API fast and tiny. Step 3: Frontend Setup (React + Chakra UI) Install frontend dependencies If you are on **Chakra v3**, run the CLI snippet...
