TelegramDataStorage 1.0.0

Telegram Data Storage

Store your data (config, session, etc.) in a telegram chat.

Description

This library allows you to store your data in Telegram itself.

It stores the serialized data in a Telegram chat message as a JSON file. The list of the stored files is stored in the channel's description.

When you save data, the library will create a new message with the data in the channel.

When you load data, the library will find the message, download the file, and deserialize the data. To retrieve the data, the library will forward the message to the same channel and delete it after downloading the file.

Usage

using TelegramDataStorage;

class SomeData : IStoredData
{
    public static string Key => "MyBeautifulData";

    public string SomeProperty { get; set; }
}

var serviceCollection = new ServiceCollection();

var config = new TelegramDataStorageConfig(
    BotToken: "1234567890:ABCdefGhIjKlmnOpqrStuVwXyz1234567890",
    ChatId: -1001234567890
);

serviceCollection.AddTelegramDataStorage(config);

var serviceProvider = serviceCollection.BuildServiceProvider();

var storage = serviceProvider.GetRequiredService<ITelegramDataStorage>();

var someData = new SomeData
{
    SomeProperty = "Some value"
};

await storage.SaveAsync(someData);

var loadedData = await storage.LoadAsync<SomeData>();

Console.WriteLine(loadedData.SomeProperty);

Advanced usage

Basically, you only need to implement the IStoredData interface and use the ITelegramDataStorage service. However, all classes are public and can be used directly or replaced with your own implementation.

For example, you can replace IDataConverter with your own implementation to add encryption or compression.

Testing

To run integration tests, you need to create a new Telegram bot and a new channel. Then, you need to set them in the appsettings.json file and run dotnet test.

To run them in docker, you need to pass the BOT_TOKEN and CHAT_ID arguments to docker build.

Limitations:

• The data size of the result JSON string should be less than 20MB.
