We are currently utilizing Storybook 5 alongside Angular 9, with Jest 26 for some of the testing procedures.
The issue we're facing arises when using Typescript version below 3.8.0 - a requirement for Angular 9's ng build --prod. This results in multiple errors related to Jest types like the following:
node_modules/@types/jest/node_modules/pretty-format/build/index.d.ts:7:36 - error TS1005: ';' expected.
Upon switching to Typescript 3.8.3, the Jest types function correctly; however, Angular is unable to build for production due to the need for a lower Typescript version.
If anyone has any solutions or suggestions on how to resolve this dilemma, please share them!
