eslint-plugin-tanstack-query-cache

ESLint rules that catch TanStack Query cache bugs when list keys are built with spreads (queryKey: [...LIST_KEY, filter]) but mutations still call setQueryData(LIST_KEY, …) — which only updates one cache entry.

Rules

| Rule | Description | | ---------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | prefix-query-key-must-use-set-queries-data | Prefer setQueriesData({ queryKey: prefix }, …) and matcher-style cancelQueries when hooks extend the key after a spread. |

Usage (flat config)

import tanstackQueryCache from "@boring-stack-pkg/eslint-plugin-tanstack-query-cache";

export default [
  {
    files: ["**/*.queries.ts"],
    plugins: { "tanstack-query-cache": tanstackQueryCache },
    rules: {
      "tanstack-query-cache/prefix-query-key-must-use-set-queries-data":
        "error",
    },
  },
];
