Do not publish .ts files on npmjs.org

[victornoel]

Hi,

Apparently, angular2-notifications is published on npmjs.org with its ts files.
This is a bad practice according to (at least) angular-cli people (see angular/angular-cli#4675 (comment)).

It would be great if the ts files were removed in future releases and optionally for the latest release too :)

Thanks!

Hi @victornoel

Sorry for responding so late.
I'm not sure about this one, why is this a bad practice?

Initially the src folder was excluded from the library but I got a lot of complaints about it.

#111 explains why it breaks things. Unless something has changed it still holds true.

[flauc]

Yes, but can't you exclude node_modules from your tsconfig and tslint?

[xealot]

node_modules is excluded by default I believe. When you include things from node_modules and typescript sees a ".d.ts" file and a ".ts" file in the same place it will look at the ts file.

Do you know of any other TS libraries that ship ts source code with the NPM module? Perhaps I'm simply mistaken in all things.

[victornoel]

I agree with @flauc that it is not a good enough reason: @xealot node_modules is NOT ignored by default, and you could/should ignore it.

I initially reported this issue because I understood from angular people that it was a bad practice (as you say @xealot, there is almost no npm module shipping their ts files). But I'm not exactly sure WHY it is a bad practice, I asked @filipesilva (angular/angular-cli#4675 (comment)) about it and I'm waiting for an answer.

Personally, I like the fact that ts files are present because I can browse the code of the dependencies I use, but it still seems it is not a practice usually followed…

@victornoel generally it's discouraged to ship TypeScript with third party libraries because it would require the consumer to replicate the complete build environment of the library. Not only typings, but potentially a specific version of ngc as well.

Publishing plain JavaScript with typings and meta data allows the consuming application to remain agnostic of the library's build environment.

[xealot]

The point still remains that if you use the "rootDir" option in your code and it's pointed to something like src this will break projects.

Which means your library isn't compatible with a subset of projects that use this TS feature. Additionally, if I exclude node_modules will that still type-check the things I import from there?

[victornoel]

@xealot you are right that there may be strange behaviour with respect to tslint typechecking if you remove node_modules! I didn't think of that :)

Thanks @filipesilva for the explanation.

[flauc]

I'll remove the src folder from the published repo, with everything you pointed out I think there really isn't any point in having it in there.

Thank you for joining in and helping out 👍
