How to define a object type in a function?

I always get this error:

Cannot reference type details_T [1] from a value position.

Here is my code:

type details_T = {
    code: string, desc: string,    
}

export default {
    data: function () {
        return {
            details: details_T =  { code : 'c', desc : 'd'}
        };
    },

    msg : function() {
        var s : string = 'tset'
        s = 100
        console.log('test')
    }

};

How to fix this?

You are mixing object initialization with type annotations. If you want to annotate function's return type you can go with:

data: function (): { details: details_T  } {
    return {
        details: { code : 'c', desc : 'd'}
    };
},
