Typesense Instantsearch Adapter

An adapter to use the awesome Instantsearch.js library with a Typesense Search Server, to build rich search interfaces.

NPM version CircleCI

Background

The good folks over at Algolia have built and open-sourced Instantsearch.js which is a collection of out-of-the-box components that you can use to build interactive search experiences swiftly.

With the adapter in this repository, you'll be able to use Instantsearch (and its React, Vue and Angular cousins) with data indexed in a Typesense search server.

If you haven't used Instantsearch before, we recommend going through their Getting Started guide here. Once you go through the guide, follow the instructions below to plug the Typesense adapter into Instantsearch.

Quick Start

Here's a guide on building a quick search interface with Typesense and InstantSearch.js: https://typesense.org/docs/0.12.0/guide/#search-ui

Here's a demo app that showcases the adapter in action: https://github.com/typesense/typesense-instantsearch-demo

Installation

$ npm install --save typesense-instantsearch-adapter

or

$ yarn add typesense-instantsearch-adapter

Since this is an adapter, it will not install the Instantsearch library automatically for you. You need to install one of the following in your application directly:

You'll find information on how to get started with each of the above libraries in their respective repos.

We'd also recommend checking out create-instantsearch-app to create your Search UI from a starter template.

Usage

With instantsearch.js

import instantsearch from "instantsearch.js";
import { searchBox, hits } from "instantsearch.js/es/widgets";
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
  server: {
    apiKey: "abcd", // Be sure to use the search-only-api-key
    nodes: [
      {
        host: "localhost",
        port: "8108",
        protocol: "http"
      }
    ]
  },
  // The following parameters are directly passed to Typesense's search API endpoint.
  //  So you can pass any parameters supported by the search endpoint below. 
  //  queryBy is required. 
  additionalSearchParameters: {
    queryBy: "name,description,categories"
  }
});
const searchClient = typesenseInstantsearchAdapter.searchClient;


const search = instantsearch({
  searchClient,
  indexName: "products"
});
search.addWidgets([
  searchBox({
    container: "#searchbox"
  }),
  hits({
    container: "#hits",
    templates: {
      item: `
        <div class="hit-name">
          {{#helpers.highlight}}{ "attribute": "name" }{{/helpers.highlight}}
        </div>
      `
    }
  })
]);

search.start();

You can add any of the Instantsearch widgets here that are supported by the adapter.

You'll also find a working example in test/support/testground. To run it, run npm run testground from the project root folder.

With react-instantsearch

import React from 'react';
import ReactDOM from 'react-dom';
import { SearchBox } from 'react-instantsearch-dom';
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
  server: {
    apiKey: "abcd", // Be sure to use the search-only-api-key
    nodes: [
      {
        host: "localhost",
        port: "8108",
        protocol: "http"
      }
    ]
  },
  // The following parameters are directly passed to Typesense's search API endpoint.
  //  So you can pass any parameters supported by the search endpoint below. 
  //  queryBy is required. 
  additionalSearchParameters: {
    queryBy: "name,description,categories"
  }
});
const searchClient = typesenseInstantsearchAdapter.searchClient;

const App = () => (
  <InstantSearch
    indexName="products"
    searchClient={searchClient}
  >
    <SearchBox />
    <Hits />
  </InstantSearch>
);

You can then add any of the Instantsearch-React widgets here that are supported by the adapter.

With vue-instantsearch

App.vue:

<template>
  <ais-instant-search :search-client="searchClient" index-name="products">
    <ais-search-box />
    <ais-hits>
      <div slot="item" slot-scope="{ item }">
        <h2>{{ item.name }}</h2>
      </div>
    </ais-hits>
  </ais-instant-search>
</template>

<script>
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
  server: {
    apiKey: "abcd", // Be sure to use the search-only-api-key
    nodes: [
      {
        host: "localhost",
        port: "8108",
        protocol: "http"
      }
    ]
  },
  // The following parameters are directly passed to Typesense's search API endpoint.
  //  So you can pass any parameters supported by the search endpoint below. 
  //  queryBy is required. 
  additionalSearchParameters: {
    queryBy: "name,description,categories"
  }
});
const searchClient = typesenseInstantsearchAdapter.searchClient;

export default {
  data() {
    return {
      searchClient,
    };
  },
};
</script>

You can then add any of the Instantsearch widgets here that are supported by the adapter.

With angular-instantsearch

// app.component.ts
import { Component } from '@angular/core';
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
  server: {
    apiKey: "abcd", // Be sure to use the search-only-api-key
    nodes: [
      {
        host: "localhost",
        port: "8108",
        protocol: "http"
      }
    ]
  },
  // The following parameters are directly passed to Typesense's search API endpoint.
  //  So you can pass any parameters supported by the search endpoint below. 
  //  queryBy is required. 
  additionalSearchParameters: {
    queryBy: "name,description,categories"
  }
});
const searchClient = typesenseInstantsearchAdapter.searchClient;

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  config = {
    indexName: 'products',
    searchClient
  };
}

You can then add any of the Instantsearch widgets here that are supported by the adapter.

Widget Specific Instructions

hierarchicalMenu

For this widget, you want to create independent fields in the collection's schema with this specific naming convention:

  • field.lvl0
  • field.lvl1
  • field.lvl2

for a nested hierarchy of field.lvl0 > field.lvl1 > field.lvl2

Each of these fields can also hold an array of values. This is useful for handling multiple hierarchies.

sortBy

When instantiating this widget, you want to set the value of the index name to this particular format:

search.addWidgets([
  sortBy({
      container: "#sort-by",
      items: [
        { label: "Default", value: "products" },
        { label: "Price (asc)", value: "products/sort/price:asc" },
        { label: "Price (desc)", value: "products/sort/price:desc" }
      ]
    })
])

The generalized pattern for the value attribute is: <index_name>[/sort/<sort_by>]. The adapter will use the value in <sort_by> as the value for the sort_by search parameter.
