eslint-plugin-styled-components-file v1.0.0

eslint-plugin-styled-components-file

Context

In project where React is used in conjunction with styled-component,
it might happen that the component can have the Rendering logic + business logic + style inside a single tsx file.

This might be confusing. Vishal Sharma introduced a nice way to segregate the style part:

The creation of a file with the extension .style.tsx for bounding the styled components.
e.g.

.
└── FooterLinkGroup/
├── FooterLinkGroup.styles.tsx <-----
├── FooterLinkGroup.test.tsx
└── FooterLinkGroup.tsx

That change it’s as simple as beneficial.
In the past file length start to increase - multiple scroll are needed from the top of the file for reaching the render function.
With the extraction of the style in a separate file the code immediately appear to be more manageable and improves the separation of concerns and the readability in the code.

In addition, importing the style with

import * as S from './LinkGroup.styles';

and using inside the JSX

<S.Title>{title}</S.Title>
{.links.map((element) => (
<S.Link
href={`${element.url}`}
>
    {element.text}
</S.Link>
))}

has the benefit that the S. makes very clear what are just normal HTML tag with a styled on it and what are “React component” with logic.

This eslint custom plugin ensure that this patter is followed.
