Bug #4669
closed
SaxonJS object is empty using Webpack
100%
Description
I am upgrading an application from Saxon 1.x to 2.0 and am running into some issues. Previously I had to modify the SaxonJS code to work with webpack, but now that 2.0 is distributed via NPM I had some hope that those customizations would no longer be necessary. However, when invoking SaxonJS.transform, I get an error that the function does not exist (the object is empty i.e. {}).
Entire codebase with WIP branch available here: https://github.com/HiltonRoscoe/CDFConverter/tree/saxonjs-upgrade

Thanks for getting in touch to let us know about the issue. I'm afraid we don't really have experience with Webpack, but I'll investigate. As you suggest, the problem here could be the same as with the use of SaxonJS in Electron (bug #4639).
Does your application run in the browser, or in Node.js? Note that the version of Saxon-JS 2 on NPM is designed for use in Node.js only; there is a separate download for the Browser platform version, because there are internal differences. I'm not sure how this fits in with using Webpack?

Yes, Webpack is designed to package code to be used on the browser side. Many npm packages are designed to work on Node or in the browser, but I take your point.
Electron is similar, there is a "web side" (the UI) that runs in Chrome, and the "node side" that provides Node functionality such as File I/O.

As previously noted, we think this is related to the bug reported in #4639. We think we've fixed that bug:
- I cloned the CDFConverter repository,
- dropped in the updated SaxonJS files,
- ran
npm install - and
npm start.
In the browser, I was able to load the sample and convert it to XML without any errors. Is that sufficient to test that it now works correctly?

I believe that fixing the SaxonJS internals to neither create nor refer to an implicit global named SaxonJS has resolved this issue.

You will need to run npm run build to run the webpack builder which will refresh the built files under /docs.
