Ref: #18217
Note that this changes the public API of
CompilerHost#resolveModuleNames
. The Host is expected to returnResolvedModuleFull
, but there is some compatibility code for "older" hosts. That code is still there, but if you compile your "older host" with a new version of TypeScript, you will get a type error if you only returnResolvedModule
.I could revert that particular change if you are not comfortable with it.
