Flowise has 3 different modules in a single mono repository.

  • server: Node backend to serve API logics
  • ui: React frontend
  • components: Langchain components

Prerequisite

Step by step

  1. Fork the official Flowise Github Repository.

  2. Clone your forked repository.

  3. Create a new branch, see guide. Naming conventions:

    • For feature branch: feature/<Your New Feature>
    • For bug fix branch: bugfix/<Your New Bugfix>.

  4. Switch to the newly created branch.

  5. Go into repository folder

    cd Flowise

  6. Install all dependencies of all modules:

    yarn install

  7. Build all the code:

    yarn build

  8. Start the app on http://localhost:3000

    yarn start

  9. For development:

    • Create .env file and specify the PORT (refer to .env.example) in packages/ui
    • Create .env file and specify the PORT (refer to .env.example) in packages/server
    • Run
    yarn dev

    Any changes made in packages/ui or packages/server will be reflected on http://localhost:8080

    For changes made in packages/components, run yarn build again to pickup the changes.

  10. After making all the changes, run

    yarn build

    and

    yarn start

    to make sure everything works fine in production.

  11. Commit code and submit Pull Request from forked branch pointing to Flowise master.
