How to Build Simple Search Component in React

import React from 'react';
import './SearchBar.scss';
class SearchBar extends React.Component {
  constructor(props) {
    super(props);
    this.state = { term: '' };
  }
  onInputChange(term) {
    const name = this.props.searchBoxName || undefined;
    this.setState({ term });
    if (this.props.onSearchTermChange) {
      this.props.onSearchTermChange({ name, term });
    }
  }
  render() {
    const name = this.props.searchBoxName || undefined;
    return (
      <div className="search-box">
        <div className="search-icon">
          <img src="http://share.ashiknesin.com/search-icon.png"></img>
        </div>
        <input
          name={name}
          className="search-input"
          id="search"
          type="text"
          placeholder="Search"
          value={this.state.term}
          onChange={event => this.onInputChange(event.target.value)}
          onKeyPress={this.props.onKeyPress || null}
        />
      </div>
    );
  }
}
