React MiniSearch

React integration for the MiniSearch client side full-text search library.

Getting Started

Installation:

First, make sure you have a compatible version of React and of MiniSearch installed.

Then, install via NPM or Yarn:

# With NPM:
npm install react-minisearch

# Or with Yarn:
yarn add react-minisearch

Usage:

There are three main ways to use react-minisearch: the useMiniSearch hook, the withMiniSearch higher-order component, or the WithMiniSearch wrapper component.

All three way take the following arguments (or props for the wrapper component):

• The initial collection of documents to add to the index. Note: this is just the initial collection, and mutating this argument won't cause reindexing. To add or remove documents after initialization, use the functions add/addAll/remove/removeAll/discard, etc.
• The MiniSearch configuration options

Using the useMiniSearch hook:

import { useMiniSearch } from 'react-minisearch'

// Documents to search amongst
const documents = [
  { id: 1, name: 'Agata' },
  { id: 2, name: 'Finn' },
  // …etc
]

// See MiniSearch for documentation on options
const miniSearchOptions = { fields: ['name'] }

const MyComponent = () => {
  const { search, searchResults } = useMiniSearch(documents, miniSearchOptions)

  const handleSearchChange = (event) => {
    search(event.target.value)
  }

  return (
    <div>
      <input type='text' onChange={handleSearchChange} placeholder='Search…' />

      <ol>
        <h3>Results:</h3>
        {
          searchResults && searchResults.map((result, i) => {
            return <li key={i}>{ result.name }</li>
          })
        }
      </ol>
    </div>
  )
}

Using the withMiniSearch higher-order component:

import { withMiniSearch } from 'react-minisearch'

const MyComponent = ({ search, searchResults }) => {

  const handleSearchChange = (event) => {
    search(event.target.value)
  }

  return (
    <div>
      <input type='text' onChange={handleSearchChange} placeholder='Search…' />

      <ol>
        <h3>Results:</h3>
        {
          searchResults && searchResults.map((result, i) => {
            return <li key={i}>{ result.name }</li>
          })
        }
      </ol>
    </div>
  )
}

// Documents to search amongst
const documents = [
  { id: 1, name: 'Agata' },
  { id: 2, name: 'Finn' },
  // …etc
]

// See MiniSearch for documentation on options
const miniSearchOptions = { fields: ['name'] }

const MyComponentWithSearch = withMiniSearch(documents, miniSearchOptions, MyComponent)

Using the WithMiniSearch wrapper component:

import { WithMiniSearch } from 'react-minisearch'

// Documents to search amongst
const documents = [
  { id: 1, name: 'Agata' },
  { id: 2, name: 'Finn' },
  // …etc
]

// See MiniSearch for documentation on options
const miniSearchOptions = { fields: ['name'] }

const MyComponent = () => (
  <WithMiniSearch documents={documents} options={miniSearchOptions}>
    {
      ({ search, searchResults }) => {
        const handleSearchChange = (event) => {
          search(event.target.value)
        }

        return (
          <div>
            <input type='text' onChange={handleSearchChange} placeholder='Search…' />

            <ol>
              <h3>Results:</h3>
              {
                searchResults && searchResults.map((result, i) => {
                  return <li key={i}>{ result.name }</li>
                })
              }
            </ol>
          </div>
        )
      }
    }
  </WithMiniSearch>
)

Provided props:

The complete set of props that are provided by react-minisearch is the same for all three ways (useMiniSearch, withMiniSearch, or WithMiniSearch):

• search(query: string, searchOptions?: SearchOptions) => void: function to be called in order to perform the search

• searchResults: T[] | null: array of search results, or null when no search was performed or search was cleared

• rawResults: SearchResult[] | null: array of raw search results from MiniSearch, including scores and match information, or null when no search was performed or search was cleared

• clearSearch() => void: function to be called in order to clear the search (setting searchResults to null)

• autoSuggest(query: string, searchOptions?: SearchOptions) => void: function to be called in order to obtain auto suggestions

• suggestions: Suggestion[] | null: array of auto suggestions, or null when auto suggestions are not used or cleared

• clearSuggestions() => void: function to be called in order to clear the suggestions (setting suggestions to null)

• add(document: T) => void: function to add a new document to the index

• addAll(documents: T[]) => void: function to add several new documents to the index in bulk

• addAllAsync(documents: T[], options?: object) => Promise<void>: same as addAll, but works asynchronously and in batches to avoid blocking the UI

• remove(document: T) => void: function to remove a document from the index

• removeById(id: any) => void: function to remove a document from the index by its ID

• removeAll(documents?: T[]) => void: function to remove several documents, or all documents, from the index

• discard(id: any) => void: discard a document by its ID (same as removeById)

• discardAll(ids: readonly any[]) => void: discard several documents at once, by their ID

• replace(document: T) => void: replace an existing document with a new version of it

• isIndexing: boolean: set to true when indexing via addAllAsync is in progress, false otherwise

• miniSearch: MiniSearch: the MiniSearch instance, for the (rare) cases when it is necessary to use it directly

In this list, the type T is a generic type that refers to the type of the document being indexed.

Many of these props correspond to methods on the MiniSearch class, as documented in the MiniSearch library.
