Tigris Go Client Library

Tigris provides an easy-to-use and intuitive interface for Go. Setting up the database is instantaneous, as well - no need for tedious configuration. You define the data model as part of the application code, which then drives the database infrastructure without you having to configure and provision database resources.

Installation

go get -u github.com/tigrisdata/tigris-client-go@latest

Usage

package main

import (
	"context"
	"time"

	"github.com/tigrisdata/tigris-client-go/fields"
	"github.com/tigrisdata/tigris-client-go/filter"
	"github.com/tigrisdata/tigris-client-go/tigris"
)

type User struct {
	Id      int `tigris:"primary_key"`
	Name    string
	Balance float64
}

func main() {
	ctx, cancel := context.WithTimeout(context.Background(), 1*time.Second)
	defer cancel()
	
	// Connect to the Tigris server
	client, err := tigris.NewClient(ctx, &tigris.Config{URL: "localhost:8081"})
	if err != nil {
		panic(err)
	}
	defer client.Close()

	// Create the database and collection if they don't exist,
	// otherwise update the schema of the collection if it already exists
	db, err := client.OpenDatabase(ctx, "hello_db", &User{})
	if err != nil {
		panic(err)
	}

	// Get the collection object, all the CRUD operations on the collection will be performed
	// through this collection object
	users := tigris.GetCollection[User](db)

	// Insert or replace user
	users.InsertOrReplace(ctx,
		&User{Id: 1, Name: "Jania McGrory", Balance: 6045.7},
		&User{Id: 2, Name: "Bunny Instone", Balance: 2948.87})

	// Read
	var user *User
	user, err = users.ReadOne(ctx, filter.Eq("Id", 1)) // find user with Id 1
	if err != nil {
		panic(err)
	}

	// Update - update user's name
	users.Update(ctx, filter.Eq("Id", 1), fields.Set("Name", "Jania McGrover"))

	// Delete - delete users with Id 1 or 2
	users.Delete(ctx, filter.Or(filter.Eq("Id", 1), filter.Eq("Id", 2)))
}

Developing

The following scripts will set up and install the dependencies needed for building and testing the client.

sh scripts/install_build_deps.sh
sh scripts/install_test_deps.sh

Once the dependencies have been installed, the tests can be run simply by

make test
