QuickSearch Component for Ink 2, demo on repl.it

Forked from @Eximchain with some upgrades to make it Ink v3.x compatible.

This re-write uses modern React, some perf optimizations, typescript, exports type definitions and adds linting/prettier.

Install

$ npm install @fforres/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:

yarn
yarn dev

Usage

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

const Demo = (props) => {
  const [result, setResult] = useState("");
  return (
    <>
      <Text>The user selected {result}.</Text>
      <Newline />
      <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

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.

(Ctrl + u, Ctrl + w)
