How Can I Get Console.log To Output The Getter Result Instead Of The String "[getter/setter]"?

In this code: function Cls() { this._id = 0; Object.defineProperty(this, 'id', { get: function() { return this._id; }, set: function(id)

Solution 1:

You can use console.log(Object.assign({}, obj));

Solution 2:

Use console.log(JSON.stringify(obj));

Solution 3:

You can define an inspect method on your object, and export the properties you are interested in. See docs here: https://nodejs.org/api/util.html#util_custom_inspection_functions_on_objects

I guess it would look something like:

functionCls() {
    this._id = 0;
    Object.defineProperty(this, 'id', {
        get: function() {
            returnthis._id;
        },
        set: function(id) {
            this._id = id;
        },
        enumerable: true
    });
};

Cls.prototype.inspect = function(depth, options) {
    return`{ 'id': ${this._id} }`
}

var obj = newCls();
obj.id = 123;
console.log(obj);
console.log(obj.id);

Solution 4:

Since Nodejs v11.5.0 you can set getters: true in the util.inspect options. See here for docs.

getters <boolean> | <string> If set to true, getters are inspected. If set to 'get', only getters without a corresponding setter are inspected. If set to 'set', only getters with a corresponding setter are inspected. This might cause side effects depending on the getter function. Default: false.

Solution 5:

I needed a pretty printed object without the getters and setters yet plain JSON produced garbage. For me as the JSON string was just too long after feeding JSON.stringify() a particularly big and nested object. I wanted it to look like and behave like a plain stringified object in the console. So I just parsed it again:

JSON.parse(JSON.stringify(largeObject))

There. If you have a simpler method, let me know.
