Inefficient recompilation #113
Description
Activity
When creating a Program, you are supposed to pass in an old Program, and SourceFiles etc that can be reused and didn't change can be reused.
Yeah, but the devil is in the detail. One cannot simply pass
ts.createCompilerHost(...)tots.createProgram(..), you should construct proper instance ofCompilerHostobject which is a large part ofLanguageService::getProgram()Anyway, I agree that we need to act at some point
Right now,
ProjectConfiguration.reset()unsets everything including theProgramandTypeScriptService. Then the next call toinit()will initialize everything from scratch. This is called byrefreshFileTree(), which is called for example after dependency installation.Afaik, this is not the intended usage. When creating a
Program, you are supposed to pass in an oldProgram, and SourceFiles etc that can be reused and didn't change can be reused. I don't think the LanguageService should be destroyed.
