I'm trying to update project dependencies and am getting a bit puzzling error:
The required JS dependency "events" is not available, it was required by "node_modules/pouchdb/lib/index-browser.js".
npm install events
So did pouchdb just... not include a dependency? reading the issues it seems like they might be doing something weird expecting the npm package to run on node but I'll try
a long time ago webpack used to do automatic polyfilling for node built-in packages, but they stopped supporting this out of the box since webpack v5 (5+ years ago)
guess that still isn't enough time for npm packages to adopt and adjust accordingly
problem is that for node you don't actually want this dependency, but for the browser you need it
tbh pouchdb isn't that actively developed
since npm packages can't tell what you are going to use this in they kinda don't have a choice
FWIW I also removed the automatic polyfilling in shadow-cljs 3+
guess I underestimated how relevant this still is 😛
okay indeed installing that just fixed the problem
thanks
After upgrading to React 18.3.1 and loading the survey-react-ui library, we get the error failed to load module$node_modules$survey_react_ui$fesm$survey_react_ui_mjs at line var module$node_modules$survey_react_ui$fesm$survey_react_ui_mjs = shadow.js.require("module$node_modules$survey_react_ui$fesm$survey_react_ui_mjs", {});
The extended class that is missing is class SurveyElementBase extends React.Component {
Any directions on how to fix?
looks like the esm variant is used. dunno why that wouldn't work but did you configure it to do that manually? the default shouldn't pick that survey_react_ui$fesm$survey_react_ui_mjs file
which shadow-cljs version do you use?
ah in project.clj still using 2.20.13
maybe just bump that
thanks
alright that was it @thheller 🤦. Thanks for suggestion!
