Release v1.27.1

🛠️ Fixes

Fix Google Pubsub Panic

The callback function for the Google client Subscribe function was configured to fetch one message per Subscribe call. Still, at times the message was being sent to a closed channel causing unexpected behaviour. Fixed the issue of receiving messages on a channel that closes only on application shutdown.

Release v1.27.0

✨ Features

1. UseMiddlewareWithContainer for Custom Middleware with Container Access
   Introduced the UseMiddlewareWithContainer method, which allows custom middleware to access the application's container. This provides access to essential services such as logging, configuration, and database instances, enabling middleware to modify request processing dynamically.

   Example Usage:

   import (
       "fmt"
       "net/http"
   
       "gofr.dev/pkg/gofr"
       "gofr.dev/pkg/gofr/container"
   )
   
   func main() {
       // Create a new GoFr application instance
       a := gofr.New()
   
       // Add custom middleware with container access
       a.UseMiddlewareWithContainer(customMiddleware)
   
      ....
   }
   
   // Define middleware with container access
   func customMiddleware(c *container.Container, handler http.Handler) http.Handler {
       return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
           c.Logger.Log("Hey! Welcome to GoFr")
           handler.ServeHTTP(w, r)
       })
   }
   ` 

2. Migrations Support in MongoDB
   GoFr now introduces support for data migrations in MongoDB, enabling seamless modifications to your database schema and data. This includes adding new fields, modifying data types of existing fields, setting or removing indexes, and applying constraints to collections. All changes are meticulously tracked in the GoFr Migrations Table, ensuring a reliable and auditable history of database updates.

🛠️ Fixes

1. Remote Log URL Setup
   Resolved an issue where logs fetched from the remote log URL were missing correlation IDs. Logs now consistently include the correlation ID, ensuring better traceability.

2. Entity DataType Documentation Update
   Enhanced the documentation for the Add-rest-handler feature by specifying supported data types in the entity structure, improving usability and reducing confusion.

3. SQL Logs Level Adjustment
   Fixed the log level for successful SQL connections, which was mistakenly set to debug. It is now appropriately logged at the info level, aligning with logging best practices.

Release v1.26.0

✨ Features

1. Support for NATS as External Pub-Sub

We have added support for NATS as an external pub/sub service in GoFr. Users can now easily set up NATS for message publishing and subscribing by configuring it via app.AddPubSub. Here’s a quick example:

app.AddPubSub(nats.New(&nats.Config{
    Server:    "nats://localhost:4222",
    CredsFile: "",
    Stream: nats.StreamConfig{
        Stream:   "my-stream",
        Subjects: []string{"order-logs", "products"},
    },
    MaxWait:     5 * time.Second,
    MaxPullWait: 500,
    Consumer:    "my-consumer",
}, app.Logger()))

To inject NATS, import it using the following command:

go get gofr.dev/pkg/gofr/datasources/pubsub/nats

Refer to our documentation for detailed setup instructions.

2. New Environment Variable DB_CHARSET

Introduced a new environment variable DB_CHARSET to make the MySQL character set configurable. By default, DB_CHARSET is set to utf8. However, setting it to utf8mb4 is recommended for full Unicode support, including emojis and special characters.

3. Enhanced CLI with TUI Elements (Spinners and Progress Bar)

This release enhances the GoFr command-line experience by introducing Text User Interface (TUI) elements, including spinners and a progress bar for visual feedback during command execution.

Check out an example in examples/sample-cmd to see this in action.

4. New Examples for Remote File Server Interaction

We’ve added new examples in the examples/using-add-filestore directory, demonstrating how to interact with remote file servers using GoFr. This addition provides a convenient reference for developers working with remote file management.

🛠️ Fixes

1. Fix: Invalid ClickHouse Documentation

Updated the ClickHouse package documentation to highlight only the relevant parts, improving readability and maintainability.

Release v1.25.0

Release v1.25.0

✨ Features

BadgerDB Tracing

• Added context support and tracing for BadgerDB datasource operations, enhancing observability and tracking within the BadgerDB storage layer.(Released pkg/gofr/datasource/kv-store/badger - v0.2.0)

Redis Authentication Support

• Users can now connect to Redis instances requiring a username, password, or both. Configure these credentials in the .env file located in the configs folder:

  • REDIS_USER: User credential for connecting to the Redis server. Multiple users with different permissions can be configured within a single Redis instance. For more details, refer to the official Redis documentation.

  • REDIS_PASSWORD: Password credential required only if authentication is enabled on the Redis instance.

Enhanced Authentication Retrieval in Context

• The GetAuthInfo method on the context provides easy access to various authentication methods, allowing developers to retrieve:

  • JWT Claims: Use GetAuthInfo().GetClaims() when OAuth is enabled, returning a jwt.MapClaims response.

  • Username: Use GetAuthInfo().GetUsername() for basic authentication, returning the username or an empty string if basic auth is not enabled.

  • API Key: Use GetAuthInfo().GetAPIKey() for API key-based authentication, returning the API key or an empty string if API key auth is not enabled.

🛠️ Fixes

Static File Route Issue

• Resolved a bug in the AddStaticFiles method where static files could not be accessed via specified routes. Now, running the following code:

  func main() {
      app := gofr.New()
      app.AddStaticFiles("/", "./static")
      app.Run()
  }

  Files within the ./static directory can be accessed properly, e.g., http://localhost:9000/abc.jpeg, without encountering a "route not registered" error.

Controlled Access to OpenAPI Files

• Prevented direct access to the openapi.json file via static routes. The file is now restricted to access through explicitly defined routes such as /.well-known/swagger or /.well-known/openapi.json for secure and controlled API documentation access.

Release v1.24.2

Release v1.24.2

🛠️ Fixes

• Tracing in Solr data source
  Fixed missing tracing for Solr data source. Now, spans for Solr data source will be visible on the trace graph with important attributes to better debug the user application.

• Cassandra logs misaligned
  The logs while running the migrations for the Cassandra database were misaligned and did not contain the exact operation that was being performed. Now logs are aligned with the other logs and also contain which operation is being performed.

• EventHub messages not getting consumed
  The Azure EventHub was not able to subscribe to the messages, fixed the flow to correctly consume the messages, and also added proper shutdown for the subscriber to close on application closure.

• Application Shutdown not working when subscribers are registered
  Now gofr applications will shutdown gracefully without getting stuck because of the forever subscription for topics.

Full Changelog: v1.24.1...v1.24.2

v1.24.1

Release v1.24.1

🛠️ Fixes:

• Google Subscriptions not calling user handlers
  Fixed a bug in the Google subscriber where messages were being consumed in the callback handler but was not calling the SubscribeFunc registered by the user.

v1.24.0

Release v1.24.0

✨ Features:

• Cassandra Tracing & Context Support:
  We’ve added context support and tracing for Cassandra operations, improving flexibility and observability. The following methods are now available:

  Single Operations:

  • QueryWithCtx: Executes queries with context, binding results to the specified destination.
  • ExecWithCtx: Executes non-query operations with context.
  • ExecCASWithCtx: Executes lightweight (CAS) transactions with context.
  • NewBatchWithCtx: Initializes a new batch operation with context.

  Batch Operations:

  • BatchQueryWithCtx: Adds queries to batch operations with context.
  • ExecuteBatchWithCtx: Executes batch operations with context.
  • ExecuteBatchCASWithCtx: Executes batch operations with context and returns the result.

  Note: The following methods in Cassandra have been deprecated:

  type Cassandra interface {
      Query(dest interface{}, stmt string, values ...any) error
      Exec(stmt string, values ...any) error
      ExecCAS(dest any, stmt string, values ...any) (bool, error)
      BatchQuery(stmt string, values ...any) error
      NewBatch(name string, batchType int) error
      CassandraBatch
  }
  
  type CassandraBatch interface {
      BatchQuery(name, stmt string, values ...any)
      ExecuteBatch(name string) error
      ExecuteBatchCAS(name string, dest ...any) (bool, error)
  }

• JWT Claims Retrieval:
  OAuth-enabled applications can now retrieve JWT claims directly within handlers. Here’s an example:

  func HelloHandler(c *gofr.Context) (interface{}, error) {
      // Retrieve the JWT claim from the context
      claimData := c.Context.Value(middleware.JWTClaim)
  
      // Assert that the claimData is of type jwt.MapClaims
      claims, ok := claimData.(jwt.MapClaims)
      if !ok {
          return nil, fmt.Errorf("invalid claim data type")
      }
  
      // Return the claims as a response
      return claims, nil
  }

🛠️ Fixes:

• Redis Panic Handling:
  Resolved an issue where calling Redis.Ping() without an active connection caused the application to panic. This is now handled gracefully.

• Docker Example Enhancement:
  The http-server example has been enhanced to include Prometheus and Grafana containers in its Docker setup, allowing users to fully explore GoFr's observability features.

v1.23.0

Release v1.23.0

• Tracing support added for MongoDB database:
  Added tracing capabilities for MongoDB database interactions, extending built-in tracing support across various MongoDB methods.

• Support for binding encoded forms:
  Added functionality for binding multipart-form data and URL-encoded form data.

  • You can use the Bind method to map form fields to struct fields by tagging them appropriately.
  • For more details, visit the documentation.

🛠️Fixes:

• Resolved nil correlationID due to uninitialized exporter:
  Addressed an issue that emerged from release v1.22.0, where the trace exporter and provider were not initialized when no configurations were specified. The isssue has been fixed. The trace provider is now set to initialize by default, regardless of the provided configuration.

v1.22.1

Release v1.22.1

✨ Fixes

• Fix clickhouse Import
  Importing clickhouse import was failing in version 1.22.0, due to otel tracer package present as indirect dependency.

v1.22.0

Release v1.22.0

✨ Features

• Support for tracing in clickhouse.
  Clickhouse Traces are now added and sent along with the respective request traces.

• Support for sampling traces.
  Traces can now be sampled based on the env config TRACER_RATIO
  It refers to the proportion of traces that are exported through sampling. It ranges between 0 to 1. By default, this ratio is set to 1, meaning all traces are exported.

• Support Azure Eventhub as external pub-sub datasource.
  Eventhub

  • Eventhub can be used similar to how messages are published and subscribed to KAFKA, MQTT and Google Pubsub.
  • To inject Eventhub import it using the following command.

    go get gofr.dev/pkg/gofr/datasources/pubsub/eventhub
    

  • Setup Eventhub by calling the AddPubSub method of gofr.

    app.AddPubSub(eventhub.New(eventhub.Config{  
     ConnectionString: "",  
     ContainerConnectionString: "",  
     StorageServiceURL: "",  
     StorageContainerName: "",  
     EventhubName: "",  
     ConsumerGroup: "",  
     }))
    

  Refer documentation to know how to get these values.

• Support to enable HTTPS in the HTTP server
  You can now secure your servers with SSL/TLS certificates by adding the certificates through following configs - CERT_FILE and KEY_FILE.

✨ Fixes

• Fix SQLite logs.
  Empty strings were coming due to difference in configuration parameters required in SQLite vs other SQL datasource when connecting which has been fixed.
