Package Exports
- react-rss
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-rss) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
react-rss
Higher order component capable of injecting RSS feed from any url into props.
So far this feed only supports standart RSS params defined in: https://validator.w3.org/feed/docs/rss2.html.
Example of usage
Display component enhanced with react-rss
import React, { FunctionComponent } from 'react';
import rssEnhancer, { InjectionRSSProps } from 'react-rss';
const DefaultRSSComponent: FunctionComponent<{ label: string } & InjectionRSSProps> = props => (
<div>
<h2>{props.label}</h2>
<a href={props.rss.header.link}>
{props.rss.header.title}
</a>
<ul>
{props.rss.items.map(item => (
<li>
{item.description}
</li>
))}
</ul>
</div>
);
export default rssEnhancer(
DefaultRSSComponent,
'https://techbeacon.com/rss.xml',
);
Component enhanced with react-rss
class SourcedRSSComponent extends Component<{ label: string } & InjectionRSSProps> {
public render() {
const { props } = this;
return (
<div>
<h2>{props.label}</h2>
<a href={props.rss.header.link}>
{props.rss.header.title}
</a>
<ul>
{props.rss.items.map(item => (
<li>
{item.description}
</li>
))}
</ul>
</div>
);
}
};
export default rssEnhancer(
SourcedRSSComponent
);
Resulting use
import React from "react";
import ReactDOM from "react-dom";
import DefaultRSSComponent from "./DefaultRSSComponent";
import SourcedRSSComponent from "./SourcedRSSComponent";
interface State {
value: string;
rssUrl: string;
}
class TestRSS extends React.Component<{}, State> {
state: State = {
value: '',
rssUrl: '',
}
public render() {
const { state } = this;
return (
<div>
<input value={state.value} onInput={e => this.setState({ value: (e.target as HTMLInputElement).value })} />
<button onClick={() => this.setState(prevState => ({ rssUrl: prevState.value }))}>Test component</button>
{state.rssUrl && (
<SourcedRSSComponent
url={state.rssUrl}
subscribe={true}
label="Sourced"
loadingComponent={() => <div>Loading sourced</div>}
errorComponent={e => {
console.error(e);
return <div>Failed to load this resource!</div>;
}}
/>
)}
<DefaultRSSComponent
label="Default"
loadingComponent={() => <div>Loading default..</div>}
errorComponent={() => <div>Sadly, no default rss :(</div>}
/>
</div>
);
}
}
ReactDOM.render(
<TestRSS />,
document.getElementById("root"),
);
Addendum
You can either setup an URL in the enhancer, or in the resulting component. However, the url has to be set. You can rewrite default url with the one on component.
