C–ATTS CLI

This CLI tool is a wrapper around the CATTS SDK. It allows you to develop, test and run C–ATTS recipes locally. The tool fetches query results, runs processor scripts, and validates schema items against the recipe's schema.

For some examples of recipes, see the catts-recipes repository.

What is C–ATTS?

C–ATTS, or Composite Attestations, is a new type of attestation that combines data from multiple sources to form a unified and verifiable credential.

To learn more, see the C–ATTS website.

Installation

Install the package globally to be able to use the catts command-line tool.

npm install -g catts-cli

CLI Usage

Querying

To fetch query results from a recipe, use the query command:

catts query <recipeFolder>

The query command will fetch the query results from the specified recipe and print them to the console. You can optionally specify the index of the query to run:

catts query <recipeFolder> -i <index>

To get more detailed output, including verbose logging, use the -v or --verbose option:

catts query <recipeFolder> -v

Running

To run a recipe, use the run command:

catts run <recipeFolder>

The run command will fetch the query results from the specified recipe, run the processor script, validate the schema items against the recipe's schema, and print the results to the console.

To get more detailed output, including verbose logging, use the -v or --verbose option:

catts run <recipeFolder> -v

Customizing the user address

The CLI needs to know a user address to fetch query results. By default, the SDK uses the USER_ETH_ADDRESS environment variable to fetch query results. If you want to use a different address, you can pass the -e or --eth-address option to the query or run commands. Alternatively, you can create a .env file in the root of your project with the USER_ETH_ADDRESS variable set to the desired address.

catts query <recipeFolder> -e <address>
catts run <recipeFolder> -e <address>
