Did you install VS2017, it installs .NET Core 1.1 with it, I believe this is part of the problem. Since the projects are still on 1.0.1, since 1.1 was released so recently.

Duplicate of #440 ?

[ManuelDeLeon]

I'll try removing .NET Core 1.1 SDK and installing v1.0.1

Duplicate of #440 ?
Probably

[ManuelDeLeon]

Yep, removing .NET Core 1.1 SDK and installing v1.0.1 fixed it (didn't uninstall VS2017)

[MarkPieszak]

The other fix is adding a global.json that tells the project to use your local 1.0.1 copy.
https://github.com/MarkPieszak/aspnetcore-angular2-universal/blob/master/global.json#L3

Glad you got it fixed! @ManuelDeLeon

I get the same error when I try to deploy to Azure App Services:

     1>Project "D:\home\site\repository\Jsservicesviewmodel.xproj" on node 1 (Publish target(s)).
     1>D:\home\site\repository\Jsservicesviewmodel.xproj(8,3): error MSB4019: The imported project "D:\Program Files (x86)\dotnet\sdk\1.0.0-preview3-004056\Extensions\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Props" was not found.

     1>Done Building Project "D:\home\site\repository\Jsservicesviewmodel.xproj" (Publish target(s)) -- FAILED.

Build FAILED.

What can I do to deploy it on Azure App Services since it doesn't like the default .xproj?

Edit: Just to be clear, that error is in the Azure logs.

[MarkPieszak]

The error came up even after adding a global.json file?

[ManuelDeLeon]

@SteveSandersonMS Any ideas what could be causing this one, we figured out the 1.1 Core issue, but now he's getting path too long etc when deploying to Azure.

It almost looks like some things didn't get installed properly through npm?

[SteveSandersonMS]

Did you remember to specify a Node version for Azure to use via WEBSITE_NODE_DEFAULT_VERSION on the Azure management portal? If you don't, it will use NPM 2.x which fails with path-too-long errors. See deployment steps at http://blog.stevensanderson.com/2016/10/04/angular2-template-for-visual-studio/#now-lets-deploy.

[ManuelDeLeon]

It has the default: WEBSITE_NODE_DEFAULT_VERSION: 4.4.7

(trying with 6.7.0)

[SteveSandersonMS]

4.4.7 is too old. It includes NPM version 2.15.8. You need NPM >=3.0 for it to work properly on Windows.

Let us know how you go with Node 6.7.0.

[ManuelDeLeon]

Different log but it still ends up with "path too long" plus there's ERROR in Cannot find module 'core-js/library/fn/symbol/iterator' in the middle.

[SteveSandersonMS]

I'm afraid I don't know why you'd still be getting the path-too-long issue if it's now actually using NPM v3.x during deployment. It makes me suspicious that maybe it's actually still using NPM 2.x. Is there any other evidence in the log to confirm what NPM version it's using?

One bit of good news is that pretty soon, issues like this will no longer be a concern. The templates are changing so that you will no longer need to deploy package.json or node_modules to production at all. The server-side prerendering feature will be able to run from completely self-contained bundles that never invoke require at runtime. So, deployments will be much faster, and won't involve NPM at all. This feature should be ready next week.

I know that doesn't fix your immediate issue right now (since the new feature hasn't shipped yet). If you're able to repro the deployment issue in a simpler way (e.g., try just deploying a completely empty site that has nothing except your package.json, and see if Kudu still fails to restore the dependencies even after confirming you're using NPM 3.x), then you might want to report that to the Azure/Kudu teams.

[MarkPieszak]

Is this a new upcoming feature to azure you're talking about, or to .NET Core and somehow caching node modules you want?

Sounds exciting either way!

[ManuelDeLeon]

Can't wait for it. What's the time frame we're talking about here? If it's a few weeks then I'll probably just wait. More than that and I'll probably keep banging my head against the wall.

About my issue, it's definitely using a new node/npm (confirmed via Azure's command line):

  "engines": {
    "node": "7.1.0",
    "npm": "3.10.9"
  },

But I'm still getting these two errors:

ERROR in ./ClientApp/boot-client.js
Module build failed: Error: Couldn't find preset "es2015" relative to directory "D:\\home\\site\\repository"

and further down:

Error: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

Are either of these due to JS Services configuration? If not, how can I contact the Azure or Kudu people?

Thanks for all the help.

[ManuelDeLeon]

Interesting, the babel-preset-es2015 folder is empty:

Maybe it's a problem with the es2015 preset version. I'll keep looking.

[ManuelDeLeon]

I'm very sorry for the trouble. As it turns out updating the node version in Azure still leaves all the deeply nested files in node_modules. It works correctly if you use a new app service and create the global.json file + set the node version from the get go. In my case I didn't know how to reset it so I had to delete the app and create it again.

Thank you for your patience.

[MarkPieszak]

Oh great so, just for clarity if anyone else runs into it:

• Deleted the app from Azure.
• Set the Azure Node version to 7 (since we require npm3+)
• Added the global.json file to pinpoint the version of .NET Core we need (1.0.1 at the moment)
• Git push the app back onto Azure

Glad you got it working!

[SteveSandersonMS]

@MarkPieszak:

Is this a new upcoming feature to azure you're talking about, or to .NET Core and somehow caching node modules you want?

It's just a change to the default Webpack config that prepares a completely standalone server-side prerendering bundle (like how the client-side bundle is completely self-contained). This means that at runtime, it never calls Node's require to load anything from node_modules, so you don't even have to deploy that dir to production.

We need this because (1) people continue to struggle with deploying node_modules correctly, especially because of NPM 2.x issues on Windows, and (2) publishing from VS is epically slow if you include 20,000+ files from node_modules. This change will mean you only have 1 or 2 (large) .js files that contain everything needed for server-side prerendering, so publishing/deployment will be just as quick and risk-free as with any other ASP.NET site.

[MarkPieszak]

I love it, that's a great idea. Yeah it seems to be a reoccurring issue :)

[SteveSandersonMS]

That feature is published now (get the latest generator-aspnetcore-spa version 0.6.1 to see it - notice that dotnet publish won't emit a node_modules dir any more, yet it still works). Let me know if you can think of any issues with this!

[MarkPieszak]

Will do, thanks again Steve!
