cross-env-test v0.1.1

cross-env-test

This command line tool works on *NIX (including OS X) and Windows. This tool checks to see if an environment variable is set to a given value:

cross-env-test NODE_ENV=testing

if NODE_ENV is set to testing the program will exit with 0 otherwise it will exit with a non-zero value

The logic is very close to:

if (process.env.NODE_ENV === 'testing') {
  process.exit(0);
} else {
  process.exit(1);
}

Usage I use this in my npm scripts:

{
  "scripts": {
    "postinstall": "cross-env-test NODE_ENV=testing || npm run build"
  }
}

Why?

Sometimes it's advantages to only run certain npm scripts sometimes. For example when running an install in an automated test environment.

Limitations

• only supports '=' and '!=' operators
• environment variable must be on the left hand side of the operator
• arguments not in the form of lh=rh or lh!=rh will cause the program to exit with an error code
• chained arguments are implicitly &&ed together
• if there is interest we can add a --or modifier
