nodebuilder 1.0.0

Shadcn-style CLI to copy LangGraph nodes and workflows into your project.

NodeBuilder

Beautifully designed, copy and paste LangGraph nodes and workflows into your project.

Installation

pip install nodebuilder

Usage

The easiest way to get started is to add a node to your project.

nodebuilder add summarizer

This will add the summarizer node to your project. You can then import and use it in your code.

from nodes.summarizer.node import SummarizerNode

# Use the node
summarizer = SummarizerNode()
result = summarizer.run("Your text to summarize here")

Add nodes from GitHub

You can also add nodes from any GitHub repository.

nodebuilder add "owner/repo node-name"

For example:

nodebuilder add "aryan/nodebuilder summarizer"
nodebuilder add "langchain-ai/langgraph-nodes translator"

Compose workflows

Create workflows by chaining multiple nodes together.

nodebuilder compose my-workflow summarizer translator

This creates a workflow that first summarizes text, then translates it.

Available nodes

• summarizer - Truncates text to 200 characters (demo summarizer)
• translator - Translates text to target language

Philosophy

• Copy, don't install - Copy the source code into your project
• Own your code - You own and control the code
• Framework ready - Works seamlessly with LangGraph
• AI friendly - Export tools for AI agents
