Set Up Multinet

  1. Clone this repository:

    $ git clone
    $ cd multinet
  2. Copy the default env file:

    $ cp .env.default .env
  3. Inspect the .env file, which contains a few useful environment variable declarations. The most important one at the moment is FLASK_SERVE_PORT, which controls which local port the server will listen on for incoming connections. This same variable also controls how the client application proxies API requests so they are routed correctly to the server.

    If the port listed in this file is not free on your system, edit the value to an alternative port number.

  4. Set the ARANGO_DATA environment variable, along with any other necessary variables. An example of this would be:

    $ echo ARANGO_DATA=~/.local/multinet/arango >> .env
  5. Start the Arango database using docker-compose:

    $ docker-compose up -d

    NOTE: macOS users may encounter errors in this step regarding filemounts denied to the Docker process; to solve this issue, create a data directory somewhere, e.g.:

    $ mkdir -p ~/.local/multinet/arango

    and then launch the Docker container using:

    $ ARANGO_DATA=~/.local/multinet/arango docker-compose up -d
  6. Use pipenv to create a virtual environment and install the dependencies:

    $ pipenv install
  7. Install the pre-commit hook:

    $ pipenv run pre-commit install

    This hook will run the Black formatter in check mode, as well as linting tests, and abort the commit if there are style errors in the code. You can fix these manually, or run black via pipenv run format to fix them automatically.

  8. Start the Multinet server:

    $ pipenv run serve

A Note on Passwords

When the Arango database is launched for the first time in Step 2 above, if the Arango data directory does not exist it will be created and populated with required startup data, including a password. The default password is letmein, but it can be set to something different through the ARANGO_PASSWORD environment variable.

When the Multinet server is started in Step 7, it will operate using the default password to communicate with Arango. Therefore, if you launched Arango using a custom password, you should launch the server with that same password, also via an ARANGO_PASSWORD environment variable.

To illustrate, if the Step 2 invocation looks like:

$ ARANGO_PASSWORD=hunter2 docker-compose up -d

then the corresponding command to launch the server in Step 5 will look like:

$ ARANGO_PASSWORD=hunter2 yarn start:server

Run Sample Client

  1. From the top-level directory, move into the client code directory:

    $ cd client
  2. Install dependencies:

    $ yarn install
  3. Build and serve the application:

    $ yarn serve
  4. Visit the sample client by opening the displayed URL (the Vue builder will choose an open port and show you).
