error TS2304: Cannot find name 'File'. about node-sdk-core HOT 8 CLOSED

ReadableStream and File types will not be imported by default unless the dom library has been included in your TypeScript config.

@AliakseiBychyk, try adding this to your tsconfig.json:

{
  ...
  "compilerOptions": {
    "lib": [
      ...
      "dom"
    ]
  }
}

As a side note, I'm not convinced that using the dom library's ReadableStream was the intention here, since the rest of this package uses the NodeJS.ReadableStream type instead. I'm happy to make a PR to change this to NodeJS.ReadableStream if you agree.

@alexpls I think that's a good idea, feel free to open that PR. Thanks

Glad to hear it's working @AliakseiBychyk!

@dpopp07 I've opened up a PR to use NodeJS.ReadableStream instead of DOM ReadableStream.

I reckon this issue can be closed now, right?

from node-sdk-core.

Resolved with #13

Thanks @alexpls

Interesting, I've not see this problem. What version of TypeScript are you using?

from node-sdk-core.

TypeScript v.3.4.2
I found that someone already described the similar issue on Stackoverflow: https://stackoverflow.com/questions/55340159/receiving-ts2304-cannot-find-name-file-ts2304-cannot-find-name-readablest

Previously I used 'watson-developer-cloud' v.3.18.1 it had build-in lib, but newer version 4.0.1 has dependency on 'ibm-cloud-sdk-core'.

@AliakseiBychyk I tried installing v3.4.2 and creating a sample project depending on v4.0.1. I am not getting any errors. Will you list some specific steps I can follow to reproduce this issue?

from node-sdk-core.

@alexpls Thanks, actually --lib dom in compiler options fixed the problem.
Since my app runs only on server-side, I didn't include 'dom' to the ts compiler options. It seems to me reasonable to change ReadableStream type to NodeJS.ReadableStream.
