Date type is Object

[DevidCIC]

Using reflect-metadata with TypeScript. On a parameter of Type Date the type a get through the reflect-metadata library is Object.

Is there no possibility to get Date back ?

I have the same problem, I can't get the Date type inside property decorator:

Reflect.getMetadata("design:type", target, propertyKey);

I get only the Object function. It works ok with number, strings, custom classes, etc. Also in sources the emitted looks ok and there's Date, not Object.

However it's weird that when I edit the JS file and add this line in the end, I got proper Date function:

let Rate = class Rate {
};
__decorate([
    Field_1.Field(type => scalars_1.Int),
    __metadata("design:type", Number)
], Rate.prototype, "value", void 0);
__decorate([
    Field_1.Field(),
    __metadata("design:type", Date)
], Rate.prototype, "date", void 0);
__decorate([
    Field_1.Field(),
    __metadata("design:type", User)
], Rate.prototype, "user", void 0);
Rate = __decorate([
    GraphQLType_1.GraphQLType()
], Rate);
exports.Rate = Rate;

console.log("date type", Reflect.getMetadata("design:type", Rate.prototype, "date"));

Looks like ts-node is the problem, when I compile the sources and run JS in node, it works great! 😉

Same problem here, I think is a ts-node issue
