I'm trying to build a standardized react button component for our enterprise library. I want to be able to use @emotion/styled to generate the styled react component. We are using rollup as our package builder, which is transpiling from typescript to esm and commonjs. When I run the build, I'm getting the following error:
Error: 'default' is not exported by node_modules\@emotion\memoize\dist\memoize.cjs.js
node_modules\@emotion\is-prop-valid\dist\is-prop-valid.esm.js (1:7)
1: import memoize from '@emotion/memoize';
I'm still learning the ins and outs of building with rollup and typescript, so I can't tell if I'm just doing something wrong, or if there's an actual issue with the @emotion libraries.
I've tried setting :
commonjs({
include: ['/node_modules/**', '../../../node_modules/**'],
namedExports: {
'node_modules/@emotion/memoize/dist/memoize.cjs.js': ['memoize']
}
})
and
commonjs({
include: ['/node_modules/**', '../../../node_modules/**'],
namedExports: {
'node_modules/@emotion/memoize/dist/memoize.cjs.js': ['default']
}
})
But neither work. I've tried installing different versions of @emotions, from 10.0.0 to 10.0.10, and it happens with all versions. I've also tried installing @emotion/memoize directly, but it also didn't work.
Here are my build settings and code:
custom-button.tsx
import React from 'react';
import CustomButtonProps from './custom-button-props';
import styled, { StyledComponent } from '@emotion/styled';
import { StyleConstants } from '@enterprise-api/constants';
export class CustomButton extends React.PureComponent<CustomButtonProps> {
public constructor(props: CustomButtonProps) {
super(props);
}
private DefaultButton: StyledComponent<any, any, any> = styled.button`
height: 2rem;
padding-left: 0.75rem;
padding-right: 0.75rem;
${StyleConstants.defaultButton}
`;
public render(): React.ReactNode {
if (this.props.style) {
return (
<button style={this.props.style} onClick={this.props.onClick}>
{this.props.text}
</button>
);
}
return <this.DefaultButton onClick={this.props.onClick}>{this.props.text}</this.DefaultButton>;
}
}
export default CustomButton;
custom-button-props.tsx
import { MouseEvent, KeyboardEvent, CSSProperties } from 'react';
export interface CustomButtonProps {
text: string;
onClick: (event: MouseEvent | KeyboardEvent) => void;
style?: CSSProperties;
}
export default CustomButtonProps;

I should be able to build this component without any issue, but instead I get the error above.
Thanks!
