The output of the entire array: console.log and console.dir "... NUM more items]" are displayed

Question

I am trying to register a long array to copy it in my terminal. However, if I try and register an array, it looks like this:

['item', 'item', >>more items<<< ... 399 more items ] 

How can I register an entire array to copy it very quickly?

Answer 1

Setting maxArrayLength

There are several methods, each of which requires setting maxArrayLength which defaults to maxArrayLength 100.

1. Provide an override as an option for console.log or console.dir

    console.log( myArry, {'maxArrayLength': null} ); 

2. Set util.inspect.defaultOptions.maxArrayLength = null; which will affect all calls to console.log and util.format

3. Call util.inspect yourself with options .

    const util = require('util') console.log(util.inspect(array, { maxArrayLength: null })) 

Answer 2

What happened to myArray.forEach(item => console.log(item)) ?

Answer 3

Using console.table

Available in Node v10 + and in all modern web browsers , you can instead use console.table() , which will display a beautiful utf8 table, where each row represents an array element.

 > console.table([{ a: 1, b: 'Y' }, { a: 'Z', b: 2 }], ['a']); ┌─────────┬─────┐ │ (index) │ a │ ├─────────┼─────┤ │ 0 │ 1 │ │ 1 │ 'Z' │ └─────────┴─────┘ 

Answer 4

Just found that the maxArrayLength option maxArrayLength well with console.dir :

console.dir(array, {depth: null, colors: true, maxArrayLength: null});

Answer 5

If you only need elements:

 for(i = 0; i < array.length; i++) console.log(array[i]); 

If you want to also copy brackets and commas:

 console.log("["); var i; // inportant to be outside for(i = 0; i < array.length - 1; i++) console.log(array[i] + ","); console.log(array[i] + "]"); 

Answer 6

Here is the solution I tested in Chrome and Firefox:

 var a = Array(400).fill("'item'"); console.log('[' + a + ']'); 

Answer 7

Michael Hellain’s answer didn’t work for me, but the close version worked

 console.dir(myArray, {'maxArrayLength': null}) 

This was the only solution that worked for me, since JSON.stringify() was too ugly for my needs, and I didn't need to write code to print it one at a time.

Answer 8

Terrible, but this will work:

 function createFullArrayString(array){ let string = '['; for(const item of array){ string += `'${item}',\n` } string = string.substring(0, string.length - 2); string += ']'; return string } console.log(createFullArrayString(array)) 

The desire was to do this in the native node.
