Strange React Compiler Behavior: node_modules\reactstrap\src\Alert.js: Unexpected token UPDATED #1334

Closed Tsyklop closed 5 years ago

Tsyklop commented 5 years ago

Issue description

What is happening?

I do the project on ReactJS. Put the reactstrap module for elements from bootstrap4.

I have reactstrap tabs. So it works. I wanted to transfer content for tabs into separate components. And here an error occurred during compilation Why?

What should be happening?

Expecting normal compilation and behavior.

Expected code:

<TabContent activeTab={this.state.activeTab}>
     <SignInTab/>
     <SignUpTab/>
     <TermsTab/>
</TabContent>

Steps to reproduce issue

Error message in console

./node_modules/reactstrap/src/Alert.js

That the error occurs in ./node_modules/reactstrap/src/Alert.js means that a component is imported from reactstrap/src/... instead of reactstrap (the latter points at reactstrap/dist/...).

The problem with importing from reactstrap/src is that it contains code that needs to be transpiled. It shouldn't be imported without a good reason because projects are usually configured to not transpile modules from node_modules, this would result in overhead and potential problems. In an application generated by create-react-app, this cannot be changed without modifying Webpack configuration.

Incorrect imports like reactstrap/src/... are often added by IDE auto-imports.

In case there's

import Alert from 'reactstrap/src/Alert.js';

import, it should be changed to

import { Alert } from 'reactstrap';
