OS independent access to variables in package.json

Question

To access a variable in npm scripts you would do something like this in your package.json:

\"scripts\": {
    \"preinstall\": \"echo ${npm_packa         


        

Answer 1

There's no known way to do this that's OS independent.

A good workaround is to execute the command within a node script:

First, change the preinstall command to execute a node script:

"scripts": {
    "preinstall": "node nameEcho.js"
}

Then you define the command in the nameEcho.js file:

// require the package.json file
var pjson = require('./package.json');

// echo the package's name
console.log(pjson.name);
