  fuzzysort






  Fast, Tiny, & Good fuzzy search for JavaScript.






  Fast: <1ms to search 13,000 files.

  


  Tiny: 1 file, 0 dependencies, 5kb.

  


  Good: clean api + sorts results well.

## Installation Node / Bun / Deno



```sh

npm i fuzzysort

```

```js

import fuzzysort from 'fuzzysort'

```

```js

const fuzzysort = require('fuzzysort')

```



## Installation Browser



```html



```



## Usage



### `fuzzysort.go(search, targets, options=null)`



```js

const mystuff = [{file: 'Apple.cpp'}, {file: 'Banana.cpp'}]

const results = fuzzysort.go('a', mystuff, {key: 'file'})

// [{score: 0.81, obj: {file: 'Apple.cpp'}}, {score: 0.59, obj: {file: 'Banana.cpp'}}]

```



### Options



```js

fuzzysort.go(search, targets, {

  threshold: 0,    // Don't return matches worse than this

  limit: 0,        // Don't return more results than this

  all: false,      // If true, returns all results for an empty search



  key: null,       // For when targets are objects (see its example usage)

  keys: null,      // For when targets are objects (see its example usage)

  scoreFn: null,   // For use with `keys` (see its example usage)

})

```



## What's a `result`



```js

const result = fuzzysort.single('query', 'some string that contains my query.')

result.score       // .80 (1 is a perfect match. 0.5 is a good match. 0 is no match.)

result.target      // 'some string that contains my query.'

result.obj         // reference to your original obj when using options.key

result.indexes     // [29, 30, 31, 32, 33]



result.highlight('', '')

// 'some string that contains my query.'



result.highlight((m, i) => {m})

// ['some string that contains my ', query, '.']

```



### Advanced Usage



Search a list of objects, by multiple complex keys, with custom weights.



```js

let objects = [{

  title: 'Liechi Berry',

  meta: {desc: 'Raises Attack when HP is low.'},

  tags: ['berries', 'items'],

  bookmarked: true,

}, {

  title: 'Petaya Berry',

  meta: {desc: 'Raises Special Attack when HP is low.'},

}]



let results = fuzzysort.go('attack berry', objects, {

  keys: ['title', 'meta.desc', obj => obj.tags?.join()],

  scoreFn: r => r.score * r.obj.bookmarked ? 2 : 1, // if the item is bookmarked, boost its score

})



var keysResult = results[0]

// When using multiple `keys`, results are different. They're indexable to get each normal result

keysResult[0].highlight() // 'Liechi Berry'

keysResult[1].highlight() // 'Raises Attack when HP is low.'

keysResult.score          // .84

keysResult.obj.title      // 'Liechi Berry'

```



## How To Go Fast · Performance Tips



```js

let targets = [{file: 'Monitor.cpp'}, {file: 'MeshRenderer.cpp'}]



// filter out targets that you don't need to search! especially long ones!

targets = targets.filter(t => t.file.length < 1000)



// if your targets don't change often, provide prepared targets instead of raw strings!

targets.forEach(t => t.filePrepared = fuzzysort.prepare(t.file))



// don't use options.key if you don't need a reference to your original obj

targets = targets.map(t => t.filePrepared)



const options = {

  limit: 100,    // don't return more results than you need!

  threshold: .5, // don't return bad results

}

fuzzysort.go('gotta', targets, options)

fuzzysort.go('go',    targets, options)

fuzzysort.go('fast',  targets, options)

```



### Gotcha

`result.score` is implemented as a getter/setter and stored different internally

`r.score = .3; // r.score == 0.30000000000000004`

- Removed `fuzzysort.indexes` & Added `result.indexes` (as a getter/setter for GC perf)

- Removed `fuzzysort.highlight()` & Added `result.highlight()`

- Changed scoring: score is now a number from 0 to 1 instead of from -Infinity to 0

- Changed scoring: substring matches are even more relevant

- Changed scoring: `straw berry` now matches great against `strawberry`

- Changed scoring: tweaked the scoring quite a bit

- `result.score` is behind a getter/setter for performance reasons

- Fixed minor issues



#### v2.0.0

- Added new behavior when your search contains spaces!
