Typesense API

Overview

This package provides an API for managing and searching Typesense collections. It offers functionalities for initializing, indexing, searching, and maintaining Typesense collections and aliases.

Features

Initialization: Ensures that all aliases point to the latest revision-based collections.
Health Check: Verifies if the Typesense client is operational.
Index Management: Lists, creates, and updates index collections.
Document Upsertion: Bulk upsert support for indexing documents.
Search Operations: Provides simple and advanced search capabilities.
Revision Management: Supports committing and reverting indexing revisions.

Installation

To use this package, add it as a dependency in your Go project:

 go get github.com/foomo/typesense

Usage example

import (
	"context"
	"time"

	"github.com/foomo/contentserver/client"
	"github.com/foomo/keel/config"
	"github.com/foomo/keel/log"
	typesenseapi "github.com/foomo/typesense/pkg/api"
	typesenseindexing "github.com/foomo/typesense/pkg/indexing"

	"github.com/typesense/typesense-go/v3/typesense"
)

func main() {
	ctx := context.Background()
	l := log.Logger()

	// contentserver client
	csClient, errClient := client.NewHTTPClient("contentserver_url")
	log.Must(l, errClient, "could not get contentserver client")

	// contentful client
	// provide list of content types
	cfClients := contentful.NewDefaultContentfulClients(ctx, l, contentful_types, true)
	cfClients.UpdateCache()
	cfClients.Client.ClientStats()

	// create typesense client
	typesenseClient := typesense.NewClient(
		typesense.WithConnectionTimeout(2*time.Minute),
		typesense.WithServer("typesense_server"),
		typesense.WithAPIKey("typesense_api_key"),
	)

	// configure document provider
	documentProvider := typesenseindexing.NewContentServer(
		l, csClient,
		GetDocumentProviderFunctions(...),  // retrieve document provider functions
		supportedMimeTypes,                 // provide supported mime types
	)

	// create typesense api
	// create indexDocument and returnType
	api := typesenseapi.NewBaseAPI[indexDocument, returnType](
		l,
		typesenseClient,
		collectionSchemas,  //map[IndexID]*api.CollectionSchema
		presetUpsertSchema, //*api.PresetUpsertSchema
	)

	// create typesense indexer
	indexer := typesenseindexing.NewBaseIndexer(
		l,
		api,
		documentProvider,
	)

	// run indexer
	err := indexer.Run(ctx)
	log.Must(l, err, "could not run indexer")
}

Health Check

err := apiInstance.Healthz(context.Background())
if err != nil {
	log.Fatalf("Health check failed: %v", err)
}

Searching Documents

Simple Search

results, scores, total, err := apiInstance.SimpleSearch(context.Background(), "products", "laptop", nil, 1, 10, "price:desc")
if err != nil {
	log.Fatalf("Search failed: %v", err)
}
log.Printf("Found %d results", total)

Advanced Search

searchParams := &api.SearchCollectionParams{
	Q:       pointer.String("laptop"),
	SortBy:  pointer.String("price:desc"),
}

results, scores, total, err = apiInstance.ExpertSearch(context.Background(), "products", searchParams)
if err != nil {
	log.Fatalf("Advanced search failed: %v", err)
}
log.Printf("Found %d results", total)
