react-rss

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.
