injectEndpoints does not have tags? [edited]

[samislam]

I have the following code:

const roomSlice = mainApi.injectEndpoints({
  tags: ['rooms'],
  endpoints: (builder) => ({
    getMany: builder.query({
      query: () => ({
        url: `/rooms`,
        providesTags: ['rooms'],
      }),
    }),
    createOne: builder.mutation({
      query: (payload) => ({
        url: '/rooms',
        method: 'POST',
        body: payload,
        invalidatesTags: ['rooms'],
      }),
    }),
  }),
})

I noticed that the tags aren't doing anything, I create a room and then I look at the table of the rooms on my webpage, and it shows out nothing is updated until I refresh the page.

Is it allowed to have tags inside injectEndpoints? if not, what are the alternatives? I have a big back-end API, and I need to split the code into multiple files somehow.

I found another question similar to this one, but it doesn't talk about
invalidatesTags: ['rooms'],
and
providesTags: ['rooms'],
and it does not give a fulfilling answer

you got the nesting wrong and there is no plain "tags" option

const roomSlice = mainApi
+.enhanceEndpoints({
+  addTagTypes: ['rooms'],
+})
.injectEndpoints({
-  tags: ['rooms'],
  endpoints: (builder) => ({
    getMany: builder.query({
      query: () => ({
        url: `/rooms`,
-       providesTags: ['rooms'],
      }),
+    providesTags: ['rooms'],
    }),
    createOne: builder.mutation({
      query: (payload) => ({
        url: '/rooms',
        method: 'POST',
        body: payload,
-      invalidatesTags: ['rooms'],
      }),
+    invalidatesTags: ['rooms'],
    }),
  }),
})

[samislam]

so it means that it's actually allowed, right? just the addTagTypes, this one must be defined inside enhanceEndpoints

[samislam]

OK, is it allowed to have the addTagTypes defined inside the mainApi slice?

[phryneas]

it could also be in mainApi. The main problem is that you got the nesting all wrong and sent it as an option to your baseQuery instead of it being an option to builder.query

@phryneas Thank you
