QuickSearch Component for Ink 2

Forked from @aicioara's original ink-quicksearch component to upgrade it to Ink 2. Big thanks to him for laying out the original logic in v1! If you are looking for a component that works with Ink v1, that's where to go. This re-write uses modern React (e.g. function components and hooks), and it is also in Typescript, improving the developer experience. The only behavioral difference is that this component always filters out items which do not match the query.

Install

$ npm install ink-quicksearch-input

Quickstart

If you'd like to get a feel for how the component works, you can see the examples in action by running:

npm install
npm start

Usage

import React, { useState } from 'react';
import { render, Text } from 'ink';
import { QuickSearchInput } from 'ink-quicksearch-input';

const Demo = (props) => {
    const [result, setResult] = useState('');
    return (
        <>
        <Text>The user selected {result}.</Text>
        {'\n'}
        <QuickSearchInput 
            items={[
                {value: 1, label: 'Animal'},
                {value: 3, label: 'Antilope'},
                {value: 2, label: 'Animation'},
                {value: 0, label: 'Animate'},
                {value: 4, label: 'Arizona'},
                {value: 5, label: 'Aria'},
                {value: 6, label: 'Arid'},
                // ...
            ]}
            onSelect={(item) => setResult(item.label)} />
        </>
    )
}

render(<Demo/>);

Props

Parameter	Type	Default	Description
items	Array(object)	[]	Items to display in a list. Each item must be an object and have at least a label prop.
onSelect	function		Function to call when user selects an item. Item object is passed to that function as an argument.
focus	boolean	true	Listen to user's input. Useful in case there are multiple input components at the same time and input must be "routed" to a specific component.
caseSensitive	boolean	false	Whether or not quicksearch matching will be case sensitive.
limit	int	0	Limit the number of rows to display. 0 is unlimited Use in conjunction with https://www.npmjs.com/package/term-size.
forceMatchingQuery	bool	false	If set to true, queries that return no results are not allowed. In particular, if previous query X returns at least one result and X + new_character would not, query will not update to X + new_character.
clearQueryChars	Array(char)	['\u0015', '\u0017'] (Ctrl + u, Ctrl + w)	Key Combinations that will clear the query. ch follows the keypress API process.stdin.on('keypress', (ch, key) => {}).
initialSelectionIndex	int	0	Selection index when the component is initially rendered or when props.items changes. Can be set together with new props.items to automatically select an option.
label	string		Optionally provide a label which will appear before the current query.
indicatorComponent	Component		Custom component to override the default indicator component (default - arrow).
itemComponent	Component		Custom component to override the default item style (default - selection coloring).
highlightComponent	Component		Custom component to override the default highlight style (default - background highlight).
statusComponent	Component		Custom component to override the status component (default - current query, optional value label).
