cross-params v1.0.4

Cross-params

This is an (over-)simplified solution for interpolating comand-line args for NPM scripts

Installation

npm:

npm install --save-dev cross-params

yarn:

yarn add -D cross-params

Usage

cross-params accepts command template as first argument, followed by actual command-line arguments. For example:

npx cross-params "yarn \${1}" --version

will result in calling

yarn --version

The syntax for template strings is following:

• ${n} where n is the argument index starting from 1

• ${key} where key is the argument key in key-value pair.

--key=value or -k=value are consiedered as key-value arguments:

npx cross-params "yarn --\${command}" --command=version

NPM scripts

Note that you should wrap command template in quotes and escape the $ symbols:

// package.json
{
    "scripts": {
    	"cross": "cross-params \"yarn \\${1}\""
    }
}

In this example you can run npm run cross --version, which will lead to calling yarn --version

Happy hacking!
