Question

What is the best way to ensure complex types are properly initialized and functioning when declaring data within a vue.js module?

Utilizing a TypeScript class that I created called Budget to initialize data for a module has been proving to be challenging.

When I attempt something like this:

currBudget: {} = { id: 20, name: 'Chris' };

everything functions as expected. However, when I try:

currBudget: Budget;

where the Budget class is imported into the component and contains the same fields declared with default values, the data does not become accessible.

Could there be some unconventional syntax in TypeScript causing this issue? Should I declare Budget as an interface instead?

Answer №1

When you use the syntax:

currBudget: Budget;

You are simply declaring currBudget as of type Budget, without initializing it.

If you want to both define its type and initialize it, you can do:

currBudget: Budget = new Budget();
