Dumping whole array: console.log and console.dir output "... NUM more items]"
提问by Anthony
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:
我正在尝试记录一个长数组，以便我可以在终端中快速复制它。但是，如果我尝试记录数组，它看起来像：
['item',
'item',
>>more items<<<
... 399 more items ]
How can I log the entire array so I can copy it really quickly?
如何记录整个阵列，以便我可以快速复制它？

Setting maxArrayLength
环境 maxArrayLength
There are a few methods all of which require setting maxArrayLengthwhich otherwise defaults to 100.
有几种方法都需要设置maxArrayLength，否则默认为 100。
Provide the override as an option to
console.dirconsole.dir(myArry, {'maxArrayLength': null});Set
util.inspect.defaultOptions.maxArrayLength = null;which will impact all calls toconsole.logandutil.formatCall
util.inspectyourself with options.const util = require('util') console.log(util.inspect(array, { maxArrayLength: null }))
提供覆盖作为选项
console.dirconsole.dir(myArry, {'maxArrayLength': null});设置
util.inspect.defaultOptions.maxArrayLength = null;将影响对console.log和的所有调用util.format呼叫
util.inspect自己与选项。const util = require('util') console.log(util.inspect(array, { maxArrayLength: null }))

Michael Hellein's answer didn't work for me, but a close version did:
Michael Hellein 的回答对我不起作用，但一个接近的版本确实如此：
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.
这是唯一对我JSON.stringify()有用的解决方案，因为它对我的需求来说太难看了，而且我不需要编写代码来一次打印一个。

Using console.table
使用 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.
在 Node v10+和所有现代 web-browsers 中可用，您可以改用console.table()它，它将输出一个漂亮的 utf8 表，其中每一行代表数组的一个元素。
> console.table([{ a: 1, b: 'Y' }, { a: 'Z', b: 2 }], ['a']);
┌─────────┬─────┐
│ (index) │ a │
├─────────┼─────┤
│ 0 │ 1 │
│ 1 │ 'Z' │
└─────────┴─────┘

Just found that option maxArrayLengthworks well with console.dirtoo:
刚刚发现该选项也maxArrayLength适用于console.dir：
console.dir(array, {depth: null, colors: true, maxArrayLength: null});
console.dir(array, {depth: null, colors: true, maxArrayLength: null});

What's wrong with myArray.forEach(item => console.log(item))?
怎么了myArray.forEach(item => console.log(item))？
