In general, to fix an “unused variable” issue you either remove the unused declaration or start using it meaningfully. Here, since the path module is not used anywhere, the safest, non‑functional‑changing fix is simply to remove the const path = require('path'); line.

Concretely, in rspack-webpack-interop/app-04/webpack.config.js, delete line 4 where path is required. No other lines need to change, and no new imports or definitions are required, because all existing usages (e.g., __dirname + '/public') are independent of path.

---

In general, to fix an unused import, you should either remove the import or start using the imported symbol where appropriate. To avoid changing existing behavior, the best option here is to remove only the unused Enhanced binding, not the entire module import, unless the module is only imported for that binding.

In this file, the line import { default as Enhanced } from '@module-federation/enhanced/webpack'; is the only reference to that module and to Enhanced, and Enhanced is never used later in the config. The minimal, behavior-preserving fix is to delete that line entirely, leaving all other imports and code unchanged.

Only one region needs modification: line 10 in remix/app2/webpack.server.js, where we will remove the unused import line.

To fix the problem, we should remove the unused Enhanced binding while preserving any potential side effects of importing @module-federation/enhanced/webpack. The general approach is either to delete the import entirely (if the module truly isn’t needed) or convert it to a side‑effect‑only import if its initialization has runtime effects.

The minimal, behavior‑preserving change here is to turn import { default as Enhanced } from '@module-federation/enhanced/webpack'; into import '@module-federation/enhanced/webpack';. This keeps the module load (and any side effects) but removes the unused variable, satisfying CodeQL’s complaint without altering any other part of the configuration. No other files or regions need modification, and no additional imports or definitions are required.

To fix this, the unused import should be removed so that the code only imports what it actually uses. This improves readability and avoids misleading future maintainers into thinking Enhanced is involved in the configuration.

Concretely, in remix/app1/webpack.server.js, delete the line importing Enhanced:

• Remove line 6: import { default as Enhanced } from '@module-federation/enhanced/webpack';

No additional methods, imports, or definitions are needed, since nothing in the shown code references Enhanced. This change does not alter existing functionality because the identifier was never used.

In general, unused imports should be removed so that the code reflects only what is actually needed, avoiding confusion and unnecessary module loading. Here, the best fix is to delete the unused Enhanced import line.

Concretely, in remix/app1/webpack.browser.js, remove line 5:

import { default as Enhanced } from '@module-federation/enhanced/webpack';

No other changes are needed: nothing else in the snippet refers to Enhanced, and we are not changing any existing functionality because the imported symbol was never used. If the project actually relies on side effects from this package, it can be reintroduced later as a side-effect-only import, but that is not evidenced in the provided code, so we will not add it.
