var wmi = require('wmi-errors')
var err = new wmi.Error(2147749890)

// Errors get a code, errno and message
console.log(err.code, err.errno)

// And have a simple hierarchy
console.log(err instanceof wmi.WbemNotFound)
console.log(err instanceof wmi.Error)
console.log(err instanceof Error)

// Create by errno, code, name or directly
throw new wmi.Error(2147749890)
throw new wmi.Error('2147749890')
throw new wmi.Error('WBEM_NOT_FOUND')
throw new wmi.Error('WbemNotFound')
throw new wmi.WbemNotFound()

// With a custom message
throw new wmi.Error('Thing was not found', 2147749890)
throw new wmi.WbemNotFound('Thing was not found')

// Wrap other error (must have a code, errno or message)
var err = new Error(2147749890)
throw new wmi.Error(err)

// That had a custom message
var inner = new Error('Custom message')
inner.code = 2147749890

// The original error is available as cause property
var outer = new wmi.Error(inner)
console.log(outer.cause === inner)

// Or give it a custom message
var inner = new Error(2147749890)
throw new wmi.Error('Custom message', inner)


With npm do:
