TypeScript via tsc command: Output to single file without concatenation

Question

Is there a way of compiling single .ts file to different directory?

The only way from the manual command of compilation to different directory is via --out command, but it also does concatenation of dependent files, which I don't want:

--out FILE|DIRECTORY        Concatenate and emit output to single file | Redirect output structure to the directory

Is there a way of redirecting the output WITHOUT concatenation of input files?

Just FYI, using --outFile limits your module generation choices to only "AMD" and "System" per the doc: typescriptlang.org/docs/handbook/compiler-options.html — Jeff Ward

Unfortunately it's impossible to compile multiple *.ts files into one *.js without concatenation. Because it's impossible on API level of typescript compile options.

See --out option:

DEPRECATED. Use --outFile instead.

Documentation of --outFile option:

Concatenate and emit output to single file. The order of concatenation is determined by the list of files passed to the compiler on the command line along with triple-slash references and imports. See output file order documentation for more details.

It does one or the other. If there's no .js extension on that file name it should assume a directory.

tsc -out output.js filea.ts fileb.ts... <- output to single file output.js

tsc -out output filea.ts fileb.ts... <- output individual files to dir output

tsc -out output/output.js filea.ts fileb.ts... <- output to single file in another directory

I think it's not a correct answer on a question. Question was Output to single file without concatenation. But here just list of --out commands

How do you get tsc to produce a flat build? By flat I mean one that doesn't have a dependancy on systemjs or requirejs? I'm trying to produce a lean build for npm.
