How to contribute?
👋 Hello there! We welcome contributions from developers of all levels to our open-source project on GitHub. If you'd like to contribute, please check our contributing guidelines and help make Langflow more accessible.
As an open-source project in a rapidly developing field, we are extremely open to contributions, whether in the form of a new feature, improved infra, or better documentation.
To contribute to this project, please follow a "fork and pull request" workflow.
Please do not try to push directly to this repo unless you are a maintainer.
Local development
You can develop Langflow using docker compose, or locally.
We provide a .vscode/launch.json file for debugging the backend in VSCode, which is a lot faster than using docker compose.
Setting up hooks:
make init
This will install the pre-commit hooks, which will run make format on every commit.
It is advised to run make lint before pushing to the repository.
Run locally
Langflow can run locally by cloning the repository and installing the dependencies. We recommend using a virtual environment to isolate the dependencies from your system.
Before you start, make sure you have the following installed:
- Poetry (>=1.4)
- Node.js
Then install the dependencies and start the development server for the backend:
make install_backend
make backend
And the frontend:
make frontend
Docker compose
The following snippet will run the backend and frontend in separate containers. The frontend will be available at localhost:3000 and the backend at localhost:7860.
docker compose up --build
# or
make dev build=1
