React Filter Search 🔍

This is a small, unobtrusive React component for filtering client-side application data.

Installation

npm i react-filter-search

yarn add react-filter-search

Usage

React Filter Search is simply a component that requires data in application state (needs to be an array of objects and an input value. In turn, you'll get back...

• filtered data based on user input
• all data in absence of any search input

This data flows back up in the form of renderResults, which is a render prop that returns one of the above. So you'll be responsible for setting up passing in data and an input value.

In this way, React Filter Search is unopinionated about how you store your data and how you handle user input in your application. 🎉

import FilterResults from 'react-filter-search';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      value: ''
    };
  }
  componentWillMount() {
    fetch('https://jsonplaceholder.typicode.com/users')
      .then(response => response.json())
      .then(json => this.setState({ data: json }));
  }
  handleChange = event => {
    const { value } = event.target;
    this.setState({ value });
  };
  render() {
    const { data, value } = this.state;
    return (
      <div>
        <input type="text" value={value} onChange={this.handleChange} />
        <SearchResults
          value={value}
          data={data}
          renderResults={results => (
            <div>
              {results.map(el => (
                <div>
                  <span>{el.name}</span>
                  <span>{el.email}</span>
                </div>
              ))}
            </div>
          )}
        />
      </div>
    );
  }
}

The magic 🧙happens in renderResults, which returns an array of objects. Your data has either been filtered based on user input, or not.

Filtering logic will iterate over any level of nesting in your data structure. Which means a good suggestion for this is something like user data or todo items that aren't heavily nested at many levels.

To render your data, simply use .map() to render to the view--the data retains in the same structure. Return some inline JSX, or feed each element into a stateless React component that renders some UI.
