Examples don't load #240

bsyouness · 2021-09-27T19:08:35Z

Description

None of the examples load as expected. Instead I get the following error in the inspector:

Blocked script execution in 'blob:http://localhost:8889/a42cb406-c95b-4137-9e18-631aae09a43b' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.
blob:http://localhost:8889/a42cb406-c95b-4137-9e18-631aae09a43b:3 GET http://localhost:8889/files/examples/example-datastore/build/bundle.example.js net::ERR_ABORTED 404 (Not Found)
Not allowed to load local resource: blob:http://localhost:8889/a3ee0a47-7c4f-4a63-bb96-3911ae656bd9

It looks like a security issue that occurs when one tries to load a local file on Chrome, which is what happens in index.html: <script type="text/javascript" src="build/bundle.example.js"></script>. I changed the code in index.html to <script sandbox="allow-scripts" type="text/javascript" src="build/bundle.example.js"></script> but then I run into:

Cross-Origin Read Blocking (CORB) blocked cross-origin response http://localhost:8889/login?next=%2Ffiles%2Fexamples%2Fexample-datastore%2Fbuild%2Fbundle.example.js with MIME type text/html. See https://www.chromestatus.com/feature/5629709824032768 for more details.

Reproduce

Open any of the example folders and open index.html.

@bsyouness you should be able to test the example after clicking on the Trust HTML button in the widget toolbar. See screencast example in the README.

blink1073 · 2021-09-30T09:21:18Z

I had noticed the same even after trusting the html, which is why we switched from binder to static html on ReadTheDocs in #241

bsyouness · 2021-09-30T13:52:00Z

blink1073 · 2021-09-30T14:38:37Z

Right, binder isn't compatible with hosting our examples

fcollonval · 2021-09-30T14:48:16Z

You need to build the example (in your screencast there is no build folder).

To do so, in the root lumino folder, you need to execute:

yarn
yarn run build:examples

Then you should be able to see the examples:

bsyouness · 2021-09-30T16:07:11Z

Thanks! That added the build folder (after I ran a lerna run build). But I'm still running into the same issue (new gif):
