Go client for the Typesense API: https://github.com/typesense/typesense

Installation

go get github.com/vamshiaruru/typesense-go

Usage

Import the the package into your code :

import "github.com/vamshiaruru/typesense-go/typesense"

Create new client:

client := typesense.NewClient(
	    typesense.WithServer("http://localhost:8108"),
	    typesense.WithAPIKey("<API_KEY>"))

New client with advanced configuration options (see godoc):

client := typesense.NewClient(
		typesense.WithServer("http://localhost:8108"),
		typesense.WithAPIKey("<API_KEY>"),
		typesense.WithConnectionTimeout(5*time.Second),
		typesense.WithCircuitBreakerMaxRequests(50),
		typesense.WithCircuitBreakerInterval(2*time.Minute),
		typesense.WithCircuitBreakerTimeout(1*time.Minute),
	)

You can also find some examples in integration tests.

Create a collection

	schema := &api.CollectionSchema{
		Name: "companies",
		Fields: []api.Field{
			{
				Name: "company_name",
				Type: "string",
			},
			{
				Name: "num_employees",
				Type: "int32",
			},
			{
				Name:  "country",
				Type:  "string",
				Facet: true,
			},
		},
		DefaultSortingField: "num_employees",
	}

	client.Collections().Create(schema)

Index a document

	document := struct {
		ID           string `json:"id"`
		CompanyName  string `json:"company_name"`
		NumEmployees int    `json:"num_employees"`
		Country      string `json:"country"`
	}{
		ID:           "123",
		CompanyName:  "Stark Industries",
		NumEmployees: 5215,
		Country:      "USA",
	}

	client.Collection("companies").Documents().Create(document)

Upserting a document

	document := struct {
		ID           string `json:"id"`
		CompanyName  string `json:"company_name"`
		NumEmployees int    `json:"num_employees"`
		Country      string `json:"country"`
	}{
		ID:           "123",
		CompanyName:  "Stark Industries",
		NumEmployees: 5215,
		Country:      "USA",
	}

	client.Collection("companies").Documents().Upsert(newDocument)

Search a collection

	searchParameters := &api.SearchCollectionParams{
		Q:        "stark",
		QueryBy:  "company_name",
		FilterBy: pointer.String("num_employees:>100"),
		SortBy:   &([]string{"num_employees:desc"}),
	}

	client.Collection("companies").Documents().Search(searchParameters)

for the supporting multiple QueryBy params, you can add , after each field

	searchParameters := &api.SearchCollectionParams{
		Q:        "stark",
		QueryBy:  "company_name, country",
		FilterBy: pointer.String("num_employees:>100"),
		SortBy:   &([]string{"num_employees:desc"}),
	}

	client.Collection("companies").Documents().Search(searchParameters)

Retrieve a document

client.Collection("companies").Document("123").Retrieve()

Update a document

	document := struct {
		CompanyName  string `json:"company_name"`
		NumEmployees int    `json:"num_employees"`
	}{
		CompanyName:  "Stark Industries",
		NumEmployees: 5500,
	}

	client.Collection("companies").Document("123").Update(document)

Delete an individual document

client.Collection("companies").Document("123").Delete()

Delete a bunch of documents

filter := &api.DeleteDocumentsParams{FilterBy: "num_employees:>100", BatchSize: 100}
client.Collection("companies").Documents().Delete(filter)

Retrieve a collection

client.Collection("companies").Retrieve()

Export documents from a collection

client.Collection("companies").Documents().Export()

Import documents into a collection

The documents to be imported can be either an array of document objects or be formatted as a newline delimited JSON string (see JSONL).

Import an array of documents:

	documents := []interface{}{
		struct {
			ID           string `json:"id"`
			CompanyName  string `json:"companyName"`
			NumEmployees int    `json:"numEmployees"`
			Country      string `json:"country"`
		}{
			ID:           "123",
			CompanyName:  "Stark Industries",
			NumEmployees: 5215,
			Country:      "USA",
		},
	}
	params := &api.ImportDocumentsParams{
		Action:    "create",
		BatchSize: 40,
	}

	client.Collection("companies").Documents().Import(documents, params)

Import a JSONL file:

	params := &api.ImportDocumentsParams{
		Action:    "create",
		BatchSize: 40,
	}
	importBody, err := os.Open("documents.jsonl")
	// defer close, error handling ...

	client.Collection("companies").Documents().ImportJsonl(importBody, params)

List all collections

client.Collections().Retrieve()

Drop a collection

client.Collection("companies").Delete()

Create an API Key

	keySchema := &api.ApiKeySchema{
		Description: "Search-only key.",
		Actions:     []string{"documents:search"},
		Collections: []string{"companies"},
		ExpiresAt:   time.Now().AddDate(0, 6, 0).Unix(),
	}

	client.Keys().Create(keySchema)

Retrieve an API Key

client.Key(1).Retrieve()

List all keys

client.Keys().Retrieve()

Delete API Key

client.Key(1).Delete()

Create or update an override

	override := &api.SearchOverrideSchema{
		Rule: api.SearchOverrideRule{
			Query: "apple",
			Match: "exact",
		},
		Includes: []api.SearchOverrideInclude{
			{
				Id:       "422",
				Position: 1,
			},
			{
				Id:       "54",
				Position: 2,
			},
		},
		Excludes: []api.SearchOverrideExclude{
			{
				Id: "287",
			},
		},
	}

	client.Collection("companies").Overrides().Upsert("customize-apple", override)

List all overrides

client.Collection("companies").Overrides().Retrieve()

Delete an override

client.Collection("companies").Override("customize-apple").Delete()

	body := &api.CollectionAliasSchema{CollectionName: "companies_june11"}
	client.Aliases().Upsert("companies", body)

Retrieve an alias

client.Alias("companies").Retrieve()

List all aliases

client.Aliases().Retrieve()

Delete an alias

client.Alias("companies").Delete()

Create or update a multi-way synonym

	synonym := &api.SearchSynonymSchema{
		Synonyms: []string{"blazer", "coat", "jacket"},
	}
	client.Collection("products").Synonyms().Upsert("coat-synonyms", synonym)

Create or update a one-way synonym

	synonym := &api.SearchSynonymSchema{
		Root:     "blazer",
		Synonyms: []string{"blazer", "coat", "jacket"},
	}
	client.Collection("products").Synonyms().Upsert("coat-synonyms", synonym)

Retrieve a synonym

client.Collection("products").Synonym("coat-synonyms").Retrieve()
