The Fauna CLI lets you access Fauna from your terminal. You can use the CLI to:

• Log in to your Fauna account.
• Create and manage Fauna databases and keys.
• Manage database schema as .fsl files on your local machine.
• Run FQL queries from files or in an interactive shell.

Node.js v18.x or later.

Install the Fauna CLI globally using npm:

npm install -g fauna-shell

To upgrade the CLI, run:

npm update -g fauna-shell

For usage instructions and a full list of commands, see the Fauna docs.

You can also access help directly in the CLI by running:

# For general help:
fauna --help

# For a specific command:
fauna <COMMAND> --help
# For example:
fauna eval --help

To test changes during development, follow these steps:

1. Install the required packages:

   yarn install

2. You can run commands in dev in one of two ways:

   • Option 1: Run against the just-in-time built project with development settings:

     # Run `fauna cloud-login` in dev:
     ./bin/dev cloud-login
     
     # Run `fauna eval` in dev:
     ./bin/dev eval

   • Option 2: Run against built assets. Use yarn link to place them in your $PATH as if globally installed:

     # Build the package and place it in your $PATH:
     yarn build && yarn link
     # Run CLI commands using `fauna ...`:
     fauna eval
