Tips for adding type definitions to an ObjectConstructor in your Typescript code within .tsx files

When I use my custom object constructor for object.keys and .values in .ts files, everything works fine. However, when I try to use them in .tsx files, the compiler interprets it as JSX and I get an error.

const myObject = (<TypedObject>Object).keys()

The usual tricks of adding a comma or extending the type with {} or unknown do not seem to work in this case.

Answer №1

When it comes to tsx, angle bracket type assertions are not allowed. Instead, utilize the as operator.

Answer №2

section, the issue was resolved by developing universal functions that output Object.(keys|values|entries), allowing for their use in various contexts.
<pre>const generateTypedObjectKeys = <T>(obj: T): KeysReturnType<T> =>
  (<TypedObject>Object).keys(obj);

</pre>
