Cannot read property 'join' of undefined path.posix

[leblancdavid]

I am getting an error when trying to login: (in microsoft-account.ts @116)

export async function getLiveKeys(options: LoadLiveKeysOptions): Promise<LiveKeys> { try { const uri: string = url.resolve(skypeLoginUri, path.posix.join("oauth", "microsoft"));

For some reason path.posix is undefined. I have the latest version of node.js. Any ideas why this would be the case?

@leblancdavid
Are you using the example in the repository or importing the library as a dependency?
If you are importing the lib as a dependency, are you using a transpiler or not? Do you use @std/esm?
What is your operating system?

It may be related to ESM imports. The package exposes both Commonjs and ESM modules.

To give you a bit more context, I'm trying to build an angular UI on top of it. I'm on windows 10. I'm trying to look at the example right now to figure out what I am missing. Here is my package.json

Could it be related to my tsconfig.json?

[demurgos]

Thanks: that's a good idea. I had a UI two years ago but did not have enough time to maintain it. I now focus on the lower-level library.

If you use Typescript, make sure that esModuleInterop and allowSyntheticDefaultImports are enabled. These are recent options required for compatibility with Node's ES modules. Your issue comes probably from the fact that your project is trying to recompile the files in the package. I'll have to check how to prevent it (or remove the TS sources, but it may hurt debugging with source maps).

In your tsconfig.json, set:

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true
  }
}

Please also note that you can theoretically swap the IO layer by your own implementation if you set the io options to an object compatible with this interface. You will most likely have to proxy the the calls if you want to use the lib in the browser or have a server with an API on top of it (so the browser can access it). Browsers also have cross-domain protection so you won't be able to replace the IO with simple XHR but it may work in something like Electron (you may need to configure a few things).
The main issue with this interface is that it's still exposing request's cookies: I haven't really tried to swap the io in a long time, but I'd like to drop this explicit dependency on request to help with the kind of thing you're trying to do.

@leblancdavid
The original issue should be solved soon: I'm on it.

As mentioned previously, this is caused by the presence of the .ts files for source maps but TS prefers .ts over .d.ts so it picks the source files instead of the definitions when compiling your project. I'll move the source files to a different directory.

[leblancdavid]

Great! I'll see if that helps. Part of me thinks that my dev environment is not configured correctly since I'm getting issues with the "esModuleInterop": true flag. In VS Code it recognizes it but when I "ng serve" it doesn't. But I can't seem to find why that is.

[demurgos]

This option was introduced in Typescript 2.7, but I see that you are using latest in your package.json so it is a bit strange. Maybe try a clean reinstall (remove node_modules and lock files).

[leblancdavid]

Yes that was the issue. I was on typescript 2.6. Updating to 2.7 fixed that esModuleInterop issue but I still can't quite compile. Unfortunately I don't think the angular-cli is up to typescript 2.7 yet. I'm getting

ERROR in node_modules/kryo/readers/qs.ts(1,17): error TS7016: Could not find a declaration file for module 'qs'. 'F:/Projects/Epyks/node_modules/qs/lib/index.js' implicitly has an 'any' type.

This may simply be because of the angular-cli since I get this warning:

@angular/compiler-cli@5.2.3 requires typescript@'>=2.4.2 <2.7.0' but 2.7.1 was found instead.
Using this version can result in undefined behaviour and difficult to debug problems.

Please run the following command to install a compatible version of TypeScript.

npm install typescript@'>=2.4.2 <2.7.0'

To disable this warning run "ng set warnings.typescriptMismatch=false".

[demurgos]

Ok, thanks for the info.
I fixed the issue in the build tools, the next release should work fine with TS 2.6: it will probably be released today or tomorrow.

[demurgos]

This issue is fixed by #87.
This ended up as a larger PR so I'll need to re-read it and clean-up some things before merging.

I also did a quick client for myself to test some features: it uses Angular for the frontend. I have custom services for contacts and conversations, but for events I just use a websocket to send them directly. WARNING: this is really messy (I use a single global instance of the Skype API, authentication is a bit brittle) but it may help you start a proper Angular client.
