Unable to import type for `SidebarItemConfig` in a typescript Docusaurus project. about docusaurus

[slorber]

Hey

This is more a question than a bug to me.

import type { SidebarItemConfig } from '@docusaurus/plugin-content-docs/lib/sidebars/types'

As far as I know, we never documented anywhere to add such import. Even if it worked, it is importing internal code and might break anytime if we refactor types.

Note that in any case, you could use TypeScript type system to "extract" the types you need. Adding an extra type export does not this ability: it only makes it more convenient.

import {SidebarsConfig} from '@docusaurus/plugin-content-docs';

type SidebarConfig = SidebarsConfig[string];
type OnlyArray<Type> = Type extends unknown[] ? Type : never;
type SidebarItemConfigArray = OnlyArray<SidebarConfig>;
type SidebarItemConfig = SidebarItemConfigArray[number];

I still don't understand why you need to import that type exactly. Please provide a repro showing the problem with the TS error you encounter, and we might eventually decide to export it to make it more convenient.

I assigned this category to a new const and dropped it into both sidebar slices, but then got an error is not assignable to type 'SidebarItemConfig'. (full error not posted, it's a big ugly TS error)

I'm not able to understand what you mean here without seeing a repro, or at least a full sidebar file example including the error messages you encounter. We'll eventually reopen if you provide enough info to understand better the problem and judge whether it's worth improving something.

My intuition is that as const could also do the trick in your case, but I can't be sure without seeing the code.
