I found a temporary workaround that helped me with this issue.
I modified this file: C:\Users\<your_username>\AppData\Local\Programs\Microsoft VS Code\resources\app\extensions\node_modules\typescript\lib\typescript.js
, and searched for WriteArrayAsGenericType
. Here's the segment I found:
if (context.flags & 2 /* WriteArrayAsGenericType */) {
const typeArgumentNode = typeToTypeNodeHelper(typeArguments[0], context);
return factory.createTypeReferenceNode(type2.target === globalArrayType ? "Array" : "ReadonlyArray", [typeArgumentNode]);
}
I changed the condition context.flags & 2
to true
. After restarting VSCode, it worked for me.
I believe this will stop working after a VSCode update, so it's just a temporary solution.
@lsby can we collaborate to have a permanent solution for this?

I believe the permanent solution would be for the TypeScript team to add the configuration option we want, but there hasn't been a response so far. Perhaps we could consider using a VSCode plugin to address this issue. Do you have any other ideas?

⭐ Suggestion
In TypeScript, when hovering over a variable, the inferred type is displayed in a specific format. For instance, an array of numbers is shown as number[]. However, some developers, including myself, prefer the alternative format
Array<number>
for readability and consistency with other generic types.📃 Motivating Example
I have noticed that there is an
WriteArrayAsGenericType
flag in the Abstract Syntax Tree (AST) that can convertT[]
toArray<T>
.I would like to request the addition of a configuration option in tsconfig.json to enable this flag, allowing developers to choose their preferred format for array types in hover tooltips.
For example:
💻 Use Cases
Complex Type Readability: I frequently write functional code that can lead to complex types like
Task<Maybe<Task<Maybe<T[]>>[]>>[]
. The shorthand[]
notation can make it difficult to understand the nested generic relationships. Displaying these types asArray<T>
would significantly improve readability and comprehension.Consistency: Most other generic types use angle brackets (e.g.,
Promise<T>
,Map<K, V>
), and only array types use the special shorthand (number[]
). Aligning array types with this convention would ensure consistency across all types and improve clarity.
