Dumping whole array: console.log and console.dir output "... NUM more items]"
Arraysnode.jsV8Dumpconsole.logArrays Problem Overview
I am trying to log a long array so I can copy it quickly in my terminal. However, if I try and log the array it looks like:
['item', 'item', >>more items<<< ... 399 more items ]
How can I log the entire array so I can copy it really quickly?

Solution 1 - Arrays
maxArrayLength
Setting There are a few methods all of which require setting maxArrayLength
which otherwise defaults to 100.
-
Provide the override as an option to
console.dir
console.dir(myArry, {'maxArrayLength': null});
-
Set
util.inspect.defaultOptions.maxArrayLength = null;
which will impact all calls toconsole.log
andutil.format
-
Call
util.inspect
yourself with options.const util = require('util') console.log(util.inspect(array, { maxArrayLength: null }))
Solution 2 - Arrays
Michael Hellein's answer didn't work for me, but a close version did:
console.dir(myArray, {'maxArrayLength': null})
This was the only solution that worked for me as JSON.stringify()
was too ugly for my needs and I didn't need to write the code to print it out one at a time.
Solution 3 - Arrays
Using console.table
Available in Node v10+, and all modern web-browsers, you can use console.table()
instead, which will output a beautiful utf8 table where each row represents an element of the array.
> console.table([{ a: 1, b: 'Y' }, { a: 'Z', b: 2 }], ['a']);
┌─────────┬─────┐
│ (index) │ a │
├─────────┼─────┤
│ 0 │ 1 │
│ 1 │ 'Z' │
└─────────┴─────┘
Solution 4 - Arrays
Just found that option maxArrayLength
works well with console.dir
too:
console.dir(array, {depth: null, colors: true, maxArrayLength: null});
Solution 5 - Arrays
What's wrong with myArray.forEach(item => console.log(item))
?
