Search-filterer NPM

search-filterer

A fuzzy search library using a slightly tweaked Damerau–Levenshtein distance algorithm. To see it in action before downloading, feel free to visit the example page

Installation

To install, use your package manager of choice:

yarn add search-filterer

npm install --save search-filterer

Exports

All functions listed here are curried and are named exports. They will return a new list consisting of items in the list that passed the checks. To use, simply

import { search, objectSearch } from "search-filterer";

const myList = ["foo", "bar", "baz"];

const results = search("bar", myList); // ["bar", "baz"]

const myListOfObjects = [
  { foo: "dog", bar: { baz: "cat" } },
  { foo: "mouse", bar: { baz: "hamster" } }
];

const objectResults = objectSearch(
  "hamster",
  ["foo", "bar.baz"],
  myListOfObjects
); // [{foo: "mouse", bar: {baz: "hamster"}}]

type search = (query: string, list: [string]) => [string];

Just a standard search. Takes a string query and a list of strings and returns a list strings, filtered down to strings that are one mutation or less away from containing the query.

type vagueSearch = (query: string, list: [string]) => [string];

Just like the search() function but a bit looser on what is accepted

type objectSearch<T> = (query: string, keys: [string], list: [T]) => [T];

Searches the list of objects using the arrays of keys, matching the, with the query. You can supply a key like "foo" to look for the value of list[0]?.foo, or supply a path using dot syntax like "foo.bar.baz" to search list[0]?.foo?.bar?.baz.

type vagueObjectSearch<T> = (query: string, keys: [string], list: [T]) => [T];

Exactly the same as objectSearch() except looser on what is accepted

type searchWithGetters<T> = (
  query: string,
  getters: [(item: T) => string],
  list: [T]
) => [T];

Searches the list of objects using the arrays of getters, matching the, with the query. This is similar to the object search, but you can use your own function to get the values out of the item. This allows for custom data structures to be used in the list.

type searchWithGetters<T> = (
  query: string,
  getters: [(item: T) => string],
  list: [T]
) => [T];

Exactly the same as searchWithGetters() except looser on what is accepted

searchPreservingOrder(), vagueSearchPreservingOrder(), objectSearchPreservingOrder(), vagueObjectSearchPreservingOrder(), searchWithGettersPreservingOrder(), searchWithGettersPreservingOrder() are all the same as their base functions, but the list returned preserves the same order as the list argument that was passed in.
