typescript outDir setting in tsconfig.json not working
Solution 1:
When you pass in files for compilation with tsc src/index.ts, your tsconfig.json is ignored.
From the documentation:
When input files are specified on the command line, tsconfig.json files are ignored.
Your npm build script should just be tsc without passing any files.
Solution 2:
If you are using the incremental compiler option, you may not be getting output if you have deleted / modified files in your outDir but have not removed the .tsbuildinfo file.
My issue was a bit different, but Google brought me here - so figured others may also.
