Cannot import certain npm modules with shadow-cljs

0 votes
in ClojureScript by

I am using shadow-cljs for my development workflow, and trying to import various npm librairies.

It works great for some like (loadash, shortid) but I get errors with others such as ecpair or crawlee.

for ecpair:

errors in file: .../node_modules/ecpair/src/ecpair.js
{:js-str-offsets [], :js-esm false, :js-imports [], :js-invalid-requires [], :goog-provides [], :js-language "es8", :goog-module nil, :js-warnings [], :resource-name "node_modules/ecpair/src/ecpair.js", :js-requires [], :js-errors [{:line 68, :column 7, :message "'(' expected"}], :goog-requires [], :tag :shadow.build.npm/errors, :uses-global-buffer false}

I am guessing this has to do with how shadow-cljs interprets those librairies, but I am not sure how to configure the shadow-cljs.edn in order to get there.

When you cross-post, please link the questions together so that different people don't attempt to solve the same issue.
