@cypress/webpack-batteries-included-preprocessor doesn't include types

[karlhorky]

Current behavior

1. ✅ The webpack preprocessor @cypress/webpack-preprocessor includes TypeScript types
2. ❌ The webpack preprocessor @cypress/webpack-batteries-included-preprocessor does not include TypeScript types

This means that imports of @cypress/webpack-batteries-included-preprocessor fail type checking:

cypress.config.ts

import webpackPreprocessor from '@cypress/webpack-batteries-included-preprocessor'; // ❌ Could not find a declaration file for module '@cypress/webpack-batteries-included-preprocessor'

Full error message:

Could not find a declaration file for module '@cypress/webpack-batteries-included-preprocessor'. '/Users/k/p/project/node_modules/@cypress/webpack-batteries-included-preprocessor/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/cypress__webpack-batteries-included-preprocessor` if it exists or add a new declaration (.d.ts) file containing `declare module '@cypress/webpack-batteries-included-preprocessor';`ts(7016)

The package @types/cypress__webpack-batteries-included-preprocessor also does not exist in DefinitelyTyped.

Desired behavior

@cypress/webpack-batteries-included-preprocessor should have types

Test code to reproduce

cypress.config.ts

import webpackPreprocessor from '@cypress/webpack-batteries-included-preprocessor'; // ❌ Could not find a declaration file for module '@cypress/webpack-batteries-included-preprocessor'

Oh I guess even a bigger problem: it is still on webpack 4 😱
