To get began, clone the challenge from GitHub.

Set up dependencies by working the next command into your terminal:

npm set up

Your folder construction ought to appear like this:

Run the next command to spin up a neighborhood server for previewing the applying:

The parts

There are three parts that make up this challenge and they’re:

• SearchBar Element: It is a easy search subject the place you kind in your search key phrase

import React from 'react';
import './SearchBar.css';
import SearchIcon from './SearchIcon';
perform SearchBar({ handleSearch, nextWord, searchValue, selectSug }) {
const handleKeyDown = (e) => {
if (e.key === 'Tab') selectSug(false, nextWord);
}
return (
<>
{ searchValue &&Hit the Tab key to just accept suggestion

}

{ searchValue && nextWord && {nextWord} } alert(searchValue)}>

</> ) } export default SearchBar;

import React from 'react';
import './Suggestion.css';
perform Suggestion({ correctionSugs, searchValue, selectSug }) {
  return (
    <>
    {

      <div className="suggestion">
          <h4 className="suggestion__header">Did you imply?</h4>
          {
            correctionSugs.map(merchandise => {

            })
          }
      </div>
    }
    </>
  )
}
export default Suggestion;

• App: That is the house element that encapsulates different parts. It performs computations and passes props to parts the place crucial

The way it works

If you kind into the enter subject, the applying makes two API calls. The primary name is for predicting the commonest subsequent phrase to your search key phrase. When this information is returned from the API, it’s saved in a state variable nextWordSug and handed as a prop to the SearchBar.js element the place it’s rendered. You’ll be able to hit the Tab button to routinely append the following phrase suggestion to your search key phrase.

attempt {
  const res = await fetch(`https://api.datamuse.com/phrases?lc=${phrase}`);
  const information = await res.json();
  if (information.size > 1) setNextWordSug(information[0].phrase);
} catch (err) {
  alert('Error occured whereas getting susggestions!');
}

attempt {
  const res = await fetch(`https://api.datamuse.com/phrases?sp=${phrase}`);
  const information = await res.json();
  let _data = [];
  for (let i = 0; i < 3; i++) {
    if (information.size >= 3) {
      if (information[0].phrase !== phrase.toLowerCase()) _data.push(information[i].phrase);
    }
    setCorrectionSugs(_data);
  }
} catch (err) {
  alert('Error occured whereas getting susggestions!');
  console.log(err);
}
