Define output folder and/or output file for declarations

[NCC1701M]

When using the declaration option the .d.ts files are all generated in the output directory of the .js files. Please provide an option to define the output directory and/or the output file for the declarations.

We would like to limit the complexity of the number of options allowed by the compiler. Can you elaborate on if/why this is a blocking issue, and if using a build tool like grunt or gulp would address the issue.

I develop a web site with node.js. IDE is Visual Studio Code. I build and run the server witth Code.

At the server I have a data model and I like to use the data model classes or rather their definitions at the client side to. But I don't want to have multiple .d.ts files in the server output folder I need them as a single .d.ts file in the client source folder.

I don't want to compile the .ts files twice (once for the server and once for the client) because it would be - in my eyes - an unnecessary step.

so why not use a build system to manage this for you?

Tried several things to compile typescript, for example gulp, but I always had problems with the created js files and their sourcemaps especially when I tried to debug. Only when compiling it with Visual Studio Code and tsc I kan debug correctly

You might want to file a bug on the gulp plugin owner's repo. Was it gulp-typescript?

[NCC1701M]

Yeah, I will file a bug, but my intention was, the change request, so that .d.ts files can be placed in an other directory, at least, they are some kind of "header files" for your .js-lib. So why should one collect those files "manually" (even with thirdparty tools) when it could be done directly when creating them?

[DanielRosenwasser]

Actually, you'll need to amend the sourceMap URL for each produced file, so it might not be a bug on their end unless the tool specifically allows you to move produced .d.ts files.

[NCC1701M]

Well I tried setting up the sourcemap url. Didn't work either

[DanielRosenwasser]

How'd you go about amending the sourcemap url?

looks like a duplicate of #6723
