Description
TypeScript Version: 2.6.0-rc
Code
# Where tsconfig.json includes hundreds of .ts files (~400 on my smallest repro project)
tsc -w tsconfig.json{
"compilerOptions": {
"declaration": true,
"experimentalDecorators": true,
"jsx": "react",
"noImplicitAny": true,
"noImplicitReturns": true,
"noImplicitThis": true,
"noResolve": true,
"pretty": true,
"sourceMap": true,
"target": "es5"
},
"include": [...]
}
Expected behavior:
After adding an unused public method to a class, it should eventually finish compilation.
Actual behavior:
After >10 minutes of waiting a few times, I've terminated the process. I've also tried reinstalling 2.6.0-rc.
Side note: on a smaller project of 28 items, with identical tsconfig settings (except that strictNullChecks is on), recompilation from adding an unused public method to a class went from ~1000ms average over 5 runs to 1500ms average (measured from the time TS outputs the File_change_detected_Starting_incremental_compilation diagnostic to the time it outputs the Compilation_complete_Watching_for_file_changes diagnostic).
The code isn't open source so I can't post it here, but I have emailed a few TypeScript team members instructions on how to get to it before (Office Sway).
