Extract src/core in a separate TS project #76785

mshustov · 2020-09-04T15:43:58Z

Summary

This PR moves src/core into a separate TS project. To do so, I had to make a few adjustments:

moved MethodKeysOf to @kbn/utility-types to able to use it in any package
added several hacks to remove core typescript dependency on data plugin & cli. These dependencies still exist in runtime. Dependency on data plugin should be removed in [core.savedObjects] Update esKuery imports to pull from new package instead of data plugin #55485
An issue to remove the dependency on CLI: Remove circular dependencies between CLI & core #76935

I didn't want to include global typings in every package.
It seems there are no reason not to update query-string to the version shipped with type definitions. We had to roll back to the old version due to compatibility issues with IE11 #59633

Can't we have a ts project for /typings and import the reference?

we already have @kbn/utility-types for standard types, I'd rather avoid creating another utility package until it's unavoidable

Unfortunately, I didn't find a way to import MockInstance & Mocked interfaces from jest package. It didn't allow me to move DeeplyMockedKeys & MockedKeys interfaces to @kbn/utility-types, since global defined jest types conflict with mocha types when importing @kbn/utility-types in /test/ folder.

The package file is also considered as an external dependency?

if you import, yes. it should gone when @kbn/utils is merged.
