Easily implement fuzzy search using a composable with Fuse.js.

From the Fuse.js website:

What is fuzzy searching?

Generally speaking, fuzzy searching (more formally known as approximate string matching) is the technique of finding strings that are approximately equal to a given pattern (rather than exactly).

Install Fuse.js as a peer dependency

NPM

bash
npm install fuse.js
npm install fuse.js

Yarn

bash
yarn add fuse.js
yarn add fuse.js

Usage

ts
import { ref } from 'vue'
import { useFuse } from '@vueuse/integrations/useFuse'

const data = [
  'John Smith',
  'John Doe',
  'Jane Doe',
  'Phillip Green',
  'Peter Brown',
]

const input = ref('Jhon D')

const { results } = useFuse(input, data)

/*
 * Results:
 *
 * { "item": "John Doe", "index": 1 }
 * { "item": "John Smith", "index": 0 }
 * { "item": "Jane Doe", "index": 2 }
 *
 */
import { ref } from 'vue'
import { useFuse } from '@vueuse/integrations/useFuse'

const data = [
  'John Smith',
  'John Doe',
  'Jane Doe',
  'Phillip Green',
  'Peter Brown',
]

const input = ref('Jhon D')

const { results } = useFuse(input, data)

/*
 * Results:
 *
 * { "item": "John Doe", "index": 1 }
 * { "item": "John Smith", "index": 0 }
 * { "item": "Jane Doe", "index": 2 }
 *
 */
