Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install multirun

It will make the multirun command available in your PATH if you"ve allowed the PATH to be modified when installing Rust. cargo uninstall multirun uninstalls.

Readme

Multirun

CLI tool for running multiple commands at once and multiplexing the output

Installation

First install the Rust compiler via https://rustup.rs, then run cargo install multirun

Usage

Create a multirun.json file then run multirun.

Sample multirun.json:

{
    "paths": {
        "DEV_ENV_FILE": "./admin/.dev.env",
    },
    "services": {
        "accounts": {
            "directory": "./accounts",
            "command": "npm run start",
            "environment": {
              "ENV_FILE": "${paths.DEV_ENV_FILE}",
              "FORCE_COLOR": "1"
            }
        },
        "compliance": {
            "directory": "./compliance",
            "command": "npm run start",
            "environment": {
              "ENV_FILE": "${paths.DEV_ENV_FILE}",
              "FORCE_COLOR": "1"
            }
        },
        "hasura": {
            "directory": ".",
            "command": "graphql-engine serve",
            "environment": {
                "HASURA_GRAPHQL_DATABASE_URL": "postgres://cw:cw@localhost/cw",
                "HASURA_GRAPHQL_AUTH_HOOK": "http://localhost:3401/hasura/auth-webhook",
                "HASURA_GRAPHQL_SERVER_PORT": "3399",
                "HASURA_GRAPHQL_ADMIN_SECRET": "amazing",
                "HASURA_GRAPHQL_ENABLE_CONSOLE": "true",
                "HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE": "true"
            }
        }
    }
}

Values of variables in the paths section and the directory field of services are resolved as paths relative to the location of the multirun.json files itself.
