FYI if you just need to remove the Topbar, an easier way is to change dist\index.html as follows:

  // Build a system
  const ui = SwaggerUIBundle({
    url: "http://petstore.swagger.io/v2/swagger.json",
    dom_id: '#swagger-ui',
    deepLinking: true,
    presets: [
      SwaggerUIBundle.presets.apis
    ]
  })

There's no need to rebuild the code in this case.

Credit goes to @shockey - #3229 (comment).

@hkosova I just tried that modification to the index...
and there is a message that flashes:
<h4 data-reactroot="">No spec provided.</h4>
before we get to see the swagger-ui.

Another option that I've been using it is to just hide it using CSS:
.topbar {display:none}

[hkosova]

@gohelkiran30 did you npm install before npm run build?

[shockey]

@heldersepu, are you providing a url parameter? If you don't provide a url, the UI doesn't have anything to do.

I see what you're describing with the latest if I omit the default url: "http://petstore.swagger.io/v2/swagger.json", in dist/index.html.

[heldersepu]

@shockey Yes I did, I changed the index.html exactly as suggested by @hkosova
I just test it, if there is no URL the message would stay, not just flash like I mentioned

[heldersepu]

@shockey Take a look here: http://nhc-noaa.azurewebsites.net/dist/index.html

@heldersepu, thanks, looking now.

@gohelkiran30, we've seen this error before (in #2845, #3027, #3153) - in all cases, the problem was different, so this particular stack trace is not helpful... thanks, npm 😄

Some questions for you:

• Did you run npm install before running npm run build?
• What OS are you using? You left that Q&A section blank.

As seen in #3027, this can be an OS-specific problem.

[shockey]

@heldersepu, ah, I see what you're saying now, the message flashes. Sorry, I missed that in your original comment!

Let's move this discussion out of this issue - I'll open a new ticket in a moment.

it was npm install issue
thanks all
