@subsquid/commands v2.3.1

@subsquid/commands

Command launcher for squids.

This tool was created as a replacement for npm scripts and Makefiles to cover the following shortcomings of both.

npm scripts:

• Hard to write complex commands.
• Commands are interpreted via the system shell, meaning the behaviour can be inconsistent across different platforms.
• No comments.
• No command descriptions to list in the overview.

make(1):

• Not cross-platform
• Esoteric and unfamiliar to many modern developers.
• No command descriptions to list in the overview.

Usage

squid-commands(1) is driven by a special commands.json file expected at the project root.

# list defined commands
squid-commands 

# path arguments and flags to the script
squid-commands clean --force

# it is ok to use from any project dir
cd child/
squid-commands build

commands.json

Below is a sample commands.json file demonstrating its features

{ // comments are ok
  "$schema": "https://subsquid.io/schemas/commands.json",
  "commands": {
    "clean": {
      "description": "delete all build artifacts",
      "cmd": ["rm", "-rf", "lib"]
    },
    "build": {
      "description": "build the project",
      "deps": ["clean"], // commands to execute before
      "cmd": ["tsc"]
    },
    "typegen": {
      "hidden": true, // Don't show in the overview listing
      "workdir": "abi", // change working dir
      "command": [
        "squid-evm-typegen", // node_modules/.bin is in the PATH
        "../src/abi",
        {"glob": "*.json"} // cross-platform glob expansion
      ],
      "env": { // additional environment variables
        "DEBUG": "*"
      }
    }
  }
