Storage

The Storage library provides a unified interface for various storage types, including SQL, NoSQL, and File. The library uses the Abstract Factory design pattern to create different storage objects.

Installation

go get github.com/golang-common-packages/storage

Features

• SQL Relational: Support for SQL databases through Go's database/sql package
• NoSQL Document: Support for MongoDB
• NoSQL Key-Value: Support for Redis, BigCache, and custom implementations
• File: Support for Google Drive and custom implementations

Usage

Import

import "github.com/golang-common-packages/storage"

Working with MongoDB

// Initialize MongoDB client
mongoClient := storage.New(context.Background(), storage.NOSQLDOCUMENT)(storage.MONGODB, &storage.Config{
    MongoDB: storage.MongoDB{
        User:     "USERNAME",
        Password: "PASSWORD",
        Hosts:    []string{"localhost:27017"},
        Options:  []string{},
        DB:       "DATABASE_NAME",
    },
}).(storage.INoSQLDocument)

// Create document
documents := []interface{}{
    map[string]interface{}{
        "name": "John Doe",
        "age":  30,
    },
}
result, err := mongoClient.Create("database", "collection", documents)

// Read document
filter := bson.M{"name": "John Doe"}
result, err := mongoClient.Read("database", "collection", filter, 10, reflect.TypeOf(YourModel{}))

// Update document
filter := bson.M{"name": "John Doe"}
update := bson.M{"$set": bson.M{"age": 31}}
result, err := mongoClient.Update("database", "collection", filter, update)

// Delete document
filter := bson.M{"name": "John Doe"}
result, err := mongoClient.Delete("database", "collection", filter)

Working with Redis

// Initialize Redis client
redisClient := storage.New(context.Background(), storage.NOSQLKEYVALUE)(storage.REDIS, &storage.Config{
    Redis: storage.Redis{
        Host:       "localhost:6379",
        Password:   "PASSWORD",
        DB:         0,
        MaxRetries: 3,
    },
}).(storage.INoSQLKeyValue)

// Store value
err := redisClient.Set("key", "value", 1*time.Hour)

// Get value
value, err := redisClient.Get("key")

// Update value
err := redisClient.Update("key", "new-value", 1*time.Hour)

// Delete value
err := redisClient.Delete("key")

Working with Google Drive

// Initialize Google Drive client
driveClient := storage.New(context.Background(), storage.FILE)(storage.DRIVE, &storage.Config{
    GoogleDrive: storage.GoogleDrive{
        PoolSize:     4,
        ByHTTPClient: false,
        Credential:   "credentials.json",
        Token:        "token.json",
    },
}).(storage.IFILE)

// List files
files, err := driveClient.List(100)

// Create folder
folder, err := driveClient.CreateFolder("folder-name")

// Upload file
file, err := os.Open("file.txt")
result, err := driveClient.Upload("file.txt", file)

// Download file
result, err := driveClient.Download("file-id")

// Move file
result, err := driveClient.Move("file-id", "old-parent-id", "new-parent-id")

// Delete file
err := driveClient.Delete([]string{"file-id"})
