Node.js - console.log does not show items in array but instead shows [Object]

Question

I have a problem with logging out the contents of an array inside an object. The actual object looks like this

   var stuff = { accepted: [ \'item1\', \'ite         


        

Answer 1

This is the default way for some browser and implementations of showing too complex or deep objects/arrays with console.log. An alternative is to use JSON.stringify with console.log:

var stuff = {
  accepted: ['item1', 'item2'],
  rejected: [],
  response: 'Foo',
  envelope: {
    from: 'The sender',
    to: ['new item1', 'new item2']
  },
  messageId: 'xxxxxxxxxxxxx'
}


console.log(JSON.stringify(stuff, null, 4));

EDIT:

Another alternative is to use console.dir in case you have a too complex or recursive object, see https://stackoverflow.com/a/27534731/6051261

Answer 2

It looks like this is an old topic, anyway

I've faced the same issue, embedded array printed as [Array].

It is because of console.log in the node.js uses util.inspect for print, the default depth is 2. So, to print something which is deeper than 2 followings can be used:

const util = require('util')
console.log(util.inspect(errors, true, 10))

Answer 3

Try it with: console.log(JSON.stringify(variable))

Answer 4

If you like Chrome devtools, that folds your json objects and let you observe a lot of things, you can use the --inspect flag:

node --inspect index.js

The console will then give you an URL and you just have to copy paste in Google Chrome to enjoy Google Chrome console.
