SharpConnector

SharpConnector is a .NET library designed to streamline integration with NoSQL databases. It provides a unified interface that simplifies database operations, eliminating the need to develop custom logic for each specific database connector. Since each NoSQL database has its own unique characteristics, such as being document-oriented or key-value-based, SharpConnector abstracts these differences, providing a consistent and simplified access layer to accelerate development.

✅ Now targeting .NET 9.

Features

• A single, generic client API for CRUD across multiple NoSQL engines
• Supported stores:
  • Key–value: Redis, EnyimMemcached, DynamoDb
  • Document: MongoDB, LiteDB, RavenDB, Couchbase
  • Multi-model: ArangoDB
• Simple configuration via appsettings.json and DI-friendly
• Sync and async operations (with CancellationToken support)
• Easy to extend: implement IOperations<T> for new connectors

Installation

You can install the library via the NuGet package manager with the following command:

dotnet add package SharpConnector

How it works

SharpConnector offers a unified interface for performing CRUD operations on various types of NoSQL databases. While NoSQL databases often differ in their internal structures (e.g., key-value stores, document databases), this library abstracts these distinctions, enabling streamlined key-value-based CRUD operations. Through SharpConnector, you can use a consistent interface to perform Insert, Get, Delete, and Update operations across multiple NoSQL systems, currently supporting:

• Redis (key-value)
• MongoDB (key-value or document-oriented)
• LiteDB (embedded document database)
• EnyimMemcached (key-value)
• RavenDB (document-oriented)
• Couchbase (document-oriented)
• DynamoDb (key-value or document-oriented)
• ArangoDB (multi-model)

SharpConnector thus simplifies the development process, providing flexibility and compatibility across diverse NoSQL paradigms without the need to handle specific database implementations.

How to use it

To get started with SharpConnector, configure the connector instance type. Then, add the specif ConnectorConfig node within your appsettings.json file:

• Redis

   {
     "ConnectorConfig": {
   	"Instance": "Redis",
   	"DatabaseNumber": 0,
   	"ConnectionString": "redisServer:6380,password=password,ssl=True,abortConnect=False"
     }
   }

• MongoDb

   {
     "ConnectorConfig": {
   	"Instance": "MongoDb",
   	"DatabaseName": "test",
   	"CollectionName": "test",
   	"ConnectionString": "mongodb_connectionstring_here"
     }
   }

• LiteDB

   {
     "ConnectorConfig": {
   	"Instance": "LiteDb",
   	"CollectionName": "test",
   	"ConnectionString": "LiteDbTest.db"
     }
   }

• Memcached

   {
     "ConnectorConfig": {
   	"Instance": "Memcached",
   	"ConnectionString": "127.0.0.1:11211"
     }
   }

• RavenDB

   {
     "ConnectorConfig": {
   	"Instance": "RavenDb",
   	"DatabaseName": "test",
   	"ConnectionString": "http://live-test.ravendb.net"
     }
   }

• Couchbase

   {
     "ConnectorConfig": {
   	"Instance": "Couchbase",
   	"ConnectionString": "couchbase://localhost",
   	"Username": "Administrator",
   	"Password": "password",
   	"BucketName": "example_bucket",
     }
   }

• DynamoDb

   {
     "ConnectorConfig": {
   	"Instance": "DynamoDb",
   	"AccessKey": "your-access-key-here",
   	"SecretKey": "your-secret-key-here",
   	"Region": "us-west-2",
   	"ServiceUrl": "https://dynamodb.us-west-2.amazonaws.com",
   	"UseHttp": false,
   	"TableName": "MyTableName"
     }
   }

• ArangoDB

   {
   	"ConnectorConfig": {
   		"Instance": "ArangoDb",
   		"ConnectionString": "http://localhost:8529",
   		"Username": "username",
   		"Password": "password",
   		"CollectionName": "test"
   	}
   }

Once configured, create a new SharpConnector client, specifying the payload type (e.g., string):

SharpConnectorClient<string> client = new SharpConnectorClient<string>()

Alternatively, you can integrate SharpConnector client using dependency injection. Here how to register the SharpConnector service with a simple string payload type:

// Register the SharpConnector services with string payload type.
builder.Services.AddSharpConnectorServices<string>();

This setup provides flexibility in working with different payload types and makes SharpConnector easy to use within dependency injection configurations.

API Overview

The main entry point is the generic ISharpConnectorClient<T>:

• T Get(string key)
• Task<T> GetAsync(string key, CancellationToken ct = default)
• IEnumerable<T> GetAll()
• Task<IEnumerable<T>> GetAllAsync(CancellationToken ct = default)
• bool Insert(string key, T value)
• bool Insert(string key, T value, TimeSpan expiration)
• Task<bool> InsertAsync(string key, T value, CancellationToken ct = default)
• Task<bool> InsertAsync(string key, T value, TimeSpan expiration, CancellationToken ct = default)
• bool InsertMany(Dictionary<string,T> values)
• bool InsertMany(Dictionary<string,T> values, TimeSpan expiration)
• Task<bool> InsertManyAsync(IEnumerable<T> values, CancellationToken ct = default)
• bool Update(string key, T value)
• Task<bool> UpdateAsync(string key, T value, CancellationToken ct = default)
• bool Delete(string key)
• Task<bool> DeleteAsync(string key, CancellationToken ct = default)
• bool Exists(string key)
• Task<bool> ExistsAsync(string key, CancellationToken ct = default)
• IEnumerable<T> Query(Func<T,bool> filter)
• Task<IEnumerable<T>> QueryAsync(Func<T,bool> filter, CancellationToken ct = default)
