@ui5/middleware-code-coverage - TypeScript support

[matz3]

Is your feature request related to a problem? Please describe.

The @ui5/middleware-code-coverage currently does not work within TypeScript based projects, e.g. created via easy-ui5 generators ts-app / ts-library.

Describe the solution you'd like

The client-side coverage feature should also be supported for TypeScript based projects.

Describe alternatives you've considered

Coverage for TypeScript sources can currently only be measured within a test-runner setup, e.g. Karma (needs karma-ui5-transpile.

Any chance typescript support is added soon?

[matz3]

It is not expected to be a straight-forward solution, which is why we didn't add it in the initial version.
We are looking into options, but it's not likely to happen in the next months - sorry.

We are in need of similar requirement. When is it planned to support typescript project generated using easyui5-tslib?

[flovogt]

@srinivas-gururao we are currently working on a concept to refactor how server middleware's are designed. See SAP/ui5-tooling#1036 The implementation of this RFC is the foundation to later offer typescript support also in @ui5/middleware-code-coverage.

We won't be able to work on this feature in the next months, but I hope to give an update in the second half of 2025.

SAP internally this feature is tracked in CPOUI5FOUNDATION-865.
