Basic usage

You pass the base string as a first argument, and a string to match it with as a second argument. The function will return an object containing the match, what comes before the match, and what comes after the match in the base string.

Hide code
() => {
  const [baseString, setBaseString] = React.useState('Seven Green Apples');
  const [stringToMatch, setStringToMatch] = React.useState('green');
  const [{ before, match, after }, updateResult] = React.useState(() =>
    getStringMatch(baseString, stringToMatch),
  );

  const matchString = () => {
    const { before, match, after } = getStringMatch(baseString, stringToMatch);
    updateResult({ before, match, after });
  };

  return (
    <Stack flexDirection="column">
      <Flex>
        <FormControl>
          <FormControl.Label>Base string</FormControl.Label>

          <TextInput
            value={baseString}
            onChange={(e) => setBaseString(e.target.value)}
          />
        </FormControl>
        <FormControl>
          <FormControl.Label>
            A string to match the base string
          </FormControl.Label>
          <TextInput
            value={stringToMatch}
            onChange={(e) => setStringToMatch(e.target.value)}
          />
        </FormControl>
      </Flex>
      <Button onClick={matchString}>Match strings</Button>
      <Heading as="h4">Results</Heading>
