engine-strict v1.0.0

Introduction

This package allow to treat npm modules as if the user had set engine-strict, it works also on npm version > 3

The package use the semver standard to check the version

// check                 
// exec node version = '1.2.3'
// engines verion specified in package.json: '1.x || >=2.5.0 || 5.0.0 - 7.2.3') 
// it return true

You can use all range types of semver.

Getting started

You need to specify in your package.json the engines you would use, for example:

...
"engines": {
  "node": "7.10.0",
  "npm": "4.2.0"
}
...

Then require the module in your main project file and run check:

// index.js
'use strict';

const engineStrict = require('node-engine-strict')

engineStrict.check()

To find the correct package.json you need to check that process.cwd() point to your project root dir, because if you use pm2 or another process manager that run your project from different folder you need to set cwd with process.chdir('path-to-project-root') command, as in the following example:

// index.js
'use strict';

const engineStrict = require('node-engine-strict')
const config = require('./config/environment')

// Set default node environment to development
process.env.NODE_ENV = process.env.NODE_ENV || 'development';

var env = process.env.NODE_ENV;

if (env === 'development' || env === 'test') {

  if (config.rootDir !== process.cwd()) {
    process.chdir(config.rootDir)
  }

  engineStrict.check()

}

// Export the application
exports = module.exports = require('./app');
