Hi @icostaykov , Please check the configuration options Both options will fix your issue. You can also take a look into the Best regards, |

In the tutorial you linked, the Did you miss to set it correctly? |

First, I would like to thank you for the really quick reply! Unfortunately, I have followed the underlined part of the tutorial carefully. I had added both |

Maybe you can attach your project to allow me to look into it? |

Yes, @petermuessig, here is the repo I created to illustrate the issue. |

Thanks for sharing your repository - now it is clear to me what's going wrong in your case. In your <script
id="sap-ui-bootstrap"
src="https://sdk.openui5.org/1.117.0/resources/sap-ui-core.js"
data-sap-ui-resourceroots='{
"com.myorg.myapp": "./",
"jspdf": "./resources/jspdf",
"jspdf-6b40b9e7": "resources/jspdf-6b40b9e7"
}'Both The other option is that you consume OpenUI5 via the local development server from HTH and BR, Peter |

One thing to add: I just solved the issue in your project but not recognizing your initial issue statement again now and your ask is different. Unfortunately, when loading UI5 via CDN, there is no real possibility to configure the resourceroots before the application is loaded - except what I do when using the Maybe one short term solution would be to put all chunks into a nested folder. I'll try that. Re-opening the issue for now, as I don't know how much time I'll have before x-mas... |
To simplify the handling of chunks of npm packages, they are now stored
in a folder with the name of the module. With this option a single
`resourceroots` mapping is sufficient to delegate all requests to the
npm package and its chunks to the proper location. This is especially
useful for CDN scenarios when the npm package is not included.
Example: CDN usage + `jspdf`
```html
<html>
<head>
[...]
<script ...
data-sap-ui-resourceroots='{
...
"jspdf": "resources/jspdf"
}'
```
Using this `resourceroots` mapping, all requests to `jspdf` and its
chunks are now resolved to `resources/jspdf*`.
* `jspdf` => `resources/jspdf.js`
* `jspdf/0c1H2u3N4k5` => `resources/jspdf/0c1H2u3N4k5.js`
Fixes #915

Thanks a lot for taking so much of your time to help out! I have an additional question that might eather make the situation better by hinting at an easy solution, or make it worse by complicating everything - importing other 3rd party libraries in some cases works without any hassle - e.g. the html2canvas library - I just have to add "html2canvas": "resources/html2canvas" without a separate entry with the hashed chunk and I am very confused why that happens. I added it to the same repo to show what I mean. |

The packaging of npm packages resolves the browser modules also from the exports section of the package.json. This provides a better coverage to detect the browser modules inside the npm packages. In addition, this fix also allows to add polyfill overrides in the current working directory. Fixes #927 Fixes #915

@icostaykov - the chunks are created when the bundler finds dynamic require/import statements - or in some special cases, when the same modules are shared by 2 or more different modules, then the rollup bundler decides to create chunks for this. With the next upcoming minor version of the ui5-tooling-modules, this may happen more often, since I plan to change the bundling in a way that I pass initially all entry modules and then let rollup decide how to bundle the whole 3rd party more effective. This is necessary to avoid conflicts, e.g. if the same module requires the same other module to avoid multiple packaging of those reused modules in other bundles. HTH... |

I would like to reopen this ticket because I have similar issue. My case is with the following third-party lib: @sap-cloud-sdk/openapi where the problem is not the chunks but somehow the lib is not even bundled and transpilled when running on dev server. More information:
ModuleError: Failed to resolve dependencies of 'ts/ui/controllers/Planner.controller.js' PS: The paths are correct so it does not seem to be the problem there. Can you please check this as well? Thanks, |
|
Let me check - but will take a little bit |
|
Hi @Kalo2412 , is there any example project you can share? THX |
|
Hi @petermuessig , i will attach an example project which is just the ui5 typescript tutorial app with the mentioned lib installed. The error is similar. Thanks in advance. |
|
Thanks @Kalo2412 - I found a few issues here and there - it's really tricky to make the SDK available via tooling-modules. The issue you reported is just the surface but an issue in the https://github.com/ui5-community/babel-plugin-transform-modules-ui5 - I need to fix the names of the imports to not allow dashes and more reserved characters. But then I stumble in bundling issues... I'll continue investigating it to provide a proper solution for you... |

Fix for naming of variables of re-exports: ui5-community/babel-plugin-transform-modules-ui5#122 Will be released with |

I just found the following docu from the Cloud SDK guys which explains the usage in React / Angular: https://sap.github.io/cloud-sdk/docs/js/guides/browser The biggest issue with the Cloud SDK is that is works somehow in the browser but it seams that it wasn't designed from scratch for that use case and therefore using a generic bundling step is cumbersome. In their docu they describe the webpack configuration to bundle it but I wonder if it still works with Angular / React. Anyways, this looks like a challenge. For UI5 they got a ticket beginning of last year but they gave up in looking into supporting UI5: SAP/cloud-sdk-js#704 😢 |
In the previous version the chunks have been sorted into subfolders which are identified as first module importing the chunks. This was done as a follow up of #915 which causes 404s when loading chunks in CDN scenarios. By putting the chunks into the folders with the name of the module requiring the chunk the module could be loaded successfully again when using resourceroots for the module. (implemented in 3.5.x version) With the enhancement to load the chunks with relative path names this feature is not necessary anymore and becomes optional so that it can be re-enabled by providing the config options chunksPath: true. In addition, the chunks are put by default flat into the resources folder. By providing the config option chunksPath: "my/chunk/path" you can provide a subfolder into which the chunks will be clustered into. When using the config option addToNamespace: true the chunksPath will be appended to the %namespace%/thirdparty path so that it is relative to the root where the modules are put into.

Describe the bug
When loading UI5 through the cdn and trying to import a third party library, following the tutorial, the third library cannot be imported. My current issue is with jsPdf, but I have faced it with another library as well. The error I get is the following:
'jspdf-16b990c3.js': failed to load 'jspdf-16b990c3.js' from https://sapui5.hana.ondemand.com/1.117.0/resources/jspdf-16b990c3.js...What seems to circumvent the issue of the missing file is adding to the resourceRoots not only
'jspdf': 'resources/jspdf', but also'jspdf-16b990c3': 'resources/jspdf-16b990c3'. However, this seems like an unreliable way to solve the issue. I am not sure how this hash at the end is being generated and cannot rely on it being the same when deployed to production.It is important to note, that there are no issues when loading UI5 locally, instead of through the CDN.
To Reproduce
Steps to reproduce the behavior:
npm i jspdforyarn add jspdfnpm startoryarn run startExpected behavior
The app should import 3rd-party libraries without any issues, regardless of UI5 being loaded through the cdn or locally.
