Compiler error "ReferenceError: require is not defined in ES module scope, you can use import instead" about swagger

[marklai1998]

I'm having this issue as well in my ESM output service.

The issue is with non-literal types like objects and enum, those are translated to a dynamic import by the plugin
then the replaceImportPath function explicitly replace import("somepath") to require("somepath")

swagger/lib/plugin/utils/plugin-utils.ts

Line 160 in 29f59e9

typeReference = typeReference.replace('import', 'require');

swagger/lib/plugin/utils/plugin-utils.ts

Line 207 in 29f59e9

typeReference: typeReference.replace('import', 'require'),

I tried to remove those two lines and it runs perfectly fine. So technically it is not blocked by the "ESM support" issue, just making it not do the string replace if the target is ESM

I found this package to do monkey patch on the build, not sure how to integrate it to the cli with watch mode capability

It references microsoft/TypeScript#43329 when mentioning this "require" import issue
I guess at some point TS only emit require for both ESM and CJS build, but now it is fixed, import/require is chosen based on the config
I guess for some reason the maintainer wanna keep existing behaviour and blindly replace it back to require

Maybe the original author can help @kamilmysliwiec
