Overview

univar lets you use one script syntax for environment variables that works on macOS/Linux (bash) and Windows (cmd). It replaces $VAR and %VAR% placeholders in your commands before execution.

Without univar, these scripts behave differently:

``jsonc
{
"scripts": {
"bash-only": "echo Hello $USER",
"win-only": "echo Hello %USERNAME%"
}
}
`

With univar, they can be unified:

`jsonc
{
"scripts": {
"greet": "univar echo Hello $USER %USERNAME%"
}
}
`

On any platform:
`bash
npm run greet


→ Hello JaneDoe JaneDoe


`

Install

`bash
npm install univar --save-dev
`

Usage

`jsonc
{
"scripts": {
"prebuild": "univar rimraf public/$npm_package_version",
"build": "univar echo Building v$npm_package_version for %USERNAME%"
}
}
`

Dev


`bash
npm test
