SweetMeSoft.GCP

Library with tools to interact with Google Cloud Platform (GCP) services.

Description

SweetMeSoft.GCP is a library for .NET Standard 2.1 that simplifies interaction with Google Cloud services, specifically with BigQuery and Cloud Storage. It provides two main classes, BigQueryRepo and GCPStorage, which act as repositories to facilitate common operations.

Main Components

BigQueryRepo

BigQueryRepo is a generic repository for performing CRUD (Create, Read, Update, Delete) operations on Google BigQuery.

Initialization

To use BigQueryRepo, you must first configure the credentials and project ID. You can do this in three ways:

1. By credentials file (JSON):

   BigQueryRepo.CredentialsFileName = "path/to/your/credentials-file.json";
   BigQueryRepo.ProjectId = "your-gcp-project-id";
   

2. By JSON content of credentials:

   BigQueryRepo.CredentialsJson = "{ \"type\": \"service_account\", ... }";
   BigQueryRepo.ProjectId = "your-gcp-project-id";
   

3. By Access Token:

   BigQueryRepo.CredentialsToken = "your-access-token";
   BigQueryRepo.ProjectId = "your-gcp-project-id";
   

Once configured, you can get the repository instance:

var repo = BigQueryRepo.Instance;

Usage

The repository uses a generic class T that must be decorated with the BigQueryTable attribute.

[BigQueryTable("my_dataset")]
public class MyEntity
{
 public Guid Id { get; set; }
 public string Name { get; set; }
 public int Age { get; set; }
}

• Insert an item:

  await repo.InsertItem(new MyEntity { ... });
  

• Get all items:

  var all = await repo.GetAll<MyEntity>();
  

• Query with conditions (LINQ):

  var result = await repo.GetByField<MyEntity>(e => e.Age > 18);
  

• Update:

  await repo.Update(myEditedEntity, e => e.Id == myEditedEntity.Id);
  

• Delete:

  await repo.Delete<MyEntity>(e => e.Name == "John");
  

GCPStorage

GCPStorage is a class for managing files in Google Cloud Storage.

Initialization

To use GCPStorage, you must provide the path to the credentials file:

GCPStorage.CredentialsFileName = "path/to/your/credentials-file.json";
var storage = GCPStorage.Instance;

Usage

• Upload a file:

  var streamFile = new StreamFile("myfile.txt", memoryStream, ContentType.txt);
  await storage.UploadFile("my-bucket", "path/inside/bucket", streamFile);
  

• Download a file:

  var downloadedFile = await storage.DownloadFile("my-bucket", "path/inside/bucket", "myfile.txt");
  

• Delete a file:

  await storage.DeleteFile("my-bucket", "path/inside/bucket", "myfile.txt");
  

• Move a file:

  await storage.MoveFile("source-bucket", "source/path", "destination-bucket", "destination/path", streamFile);
