I'm able to reproduce this - thanks for reporting!

[shockey]

The problem here is that we're importing the bundle and Standalone preset in the main file for the module.

This is great for people using swagger-ui-dist in a webapp (see #3126), but isn't getting along well with Node.

We can't remove the references, because that would be a breaking change - we'd have to bump the major version for swagger-ui-dist, which is not acceptable because we want to track swagger-ui's version. It would also completely drop a community-contributed feature, which isn't great.

It may be possible to detect at runtime what context we're running in. I'm going to try out some solutions and try to get this fixed by Friday.

To all - comments and PRs around this are welcome.

We are facing this issue with swagger api.
Appreciate the early solution to this issue.

This should be fixed next time the projects are released - I wrapped the require calls for the SwaggerUIBundle and SwaggerUIStandalonePreset in a try/catch in #3336, which should keep the whole module from exploding when that happens in a Node context.

I'll close this issue once the projects are released with a fix - once that's done, I invite everyone that has commented to update whether the issue is resolved from your end.

Releasing now, so this fix should be live shortly.

Hi
I am working on swagger-ui. But I am getting this issue::
swagger-ui-standalone-preset.js:2 Uncaught SyntaxError: Unexpected token <
(index):76 Uncaught ReferenceError: SwaggerUIBundle is not defined
at window.onload ((index):76)

[shockey]

@chaitralisk, are you sure you're loading swagger-ui-bundle.js into your page? I get a similar error if I comment out this line.

[chaitralisk]

Yes, I am loadingswagger-ui-bundle.js into page.I have created nodejs server which will load index.html file.
But I am getting:
swagger-ui-standalone-preset.js:2 Uncaught SyntaxError: Unexpected token <
(index):76 Uncaught ReferenceError: SwaggerUIBundle is not defined
at window.onload ((index):76)

[shockey]

@chaitralisk, can you please open a new ticket so we can help you with this? I want to minimize the noise for the five people getting emails about this thread.
