possibility to pipe output without creating temp files

[koutsenko]

Now compiler writes the output to disk only.
How can I compile .ts in memory?
I searched and found no results.

Thanks.

Are you looking for the compiler API to do this? https://github.com/Microsoft/TypeScript/wiki/Using-the-Compiler-API

Or is there some other scenario you have in mind?

This is currently an issue tracked by #1226.

In addition to @danquirk's response, if you are looking to do intermediate processing, you can use our compiler API, or utilize something like typescript-simple which also uses our API.

Could you describe whether either of these sufficiently answers your question?

It's just for build script written on pure node js script without any grunt, gulp and other trendy odd stuff.
TS->JS compilation result isn't the build process endpoint.
I want optimize result (Google Closure Compiler in advanced mode), then minify it.
So, transient disk writes slowing down the process a bit.

Seems I need to use compiler API and write customized CompilerHost.
Thanks for the answers and sorry for any inconveniences.

In that case, you'd probably be able to get away with creating a default compiler host and overwriting the writeFile function. It actually shouldn't be terribly difficult to set up.
