Get Search Suggestions While Typing in React

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we're going to see how to get search suggestions while typing in React with simple steps. Using simple search field and put some search query then it shows the related or suggested query to us. Just show a view beneath the TextInput that will contain a list of matching words with the input text, and you can control that views visibility when user selects a word from the list. To implement this task, use the ready-made code snippet below by just copying the code and paste it in your IDE with React library. Explore more top trending libraries and code snippet on kandi.

const GithubSearcher = () => {
  const [repos, setRepos] = React.useState();

  const getGithubRepo = q => {
    fetch("https://api.github.com/search/repositories?q=" + q)
      .then(res => {
        return res.json();
      })
      .then(json => {
        let formattedJson = json.items.map(itm => {
          return itm.name;
        })
        setRepos(formattedJson);
      });
  }

  const handleOnChange = event => {
    let qry = event.target.value;
    if(qry) { 
      setTimeout(() => {
        getGithubRepo(qry);
      }, 500);
    } else {
      setRepos("");
    }
  };

  return (
    <div>
      <p>Search Github</p>
      <input onChange={event => handleOnChange(event)} type="text" />
      <pre>
        {repos ? "Repo Names:" + JSON.stringify(repos, null, 2) : ""}
      </pre>
    </div>
  );
};

ReactDOM.render(<GithubSearcher />, document.body);
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.6/umd/react.production.min.js"></script>

Instructions

Follow the steps carefully to get the output easily.

Install the Node.js and React on your IDE(preferable Visual Studio Code).
Create React Application using npx create-react-app foldername.
cd foldername.
Open the folder in IDE.
Copy the code using "copy" button above and paste it in index.js file(remove the earlier code from index.js) then paste the script tag in index.html file.
Import React and ReactDOM in index.js file.
Add export default statement at end of the code(like 'export default GithubSearcher;').
Open the terminal from IDE.
npm start to run the file.
