Package middlewares

This package provides various HTTP middleware functions to enhance the functionality and reliability of an HTTP server application.

Functions

3. RecoveryMiddleware

A middleware function that recovers from panics, logs errors with stack traces, sends an alert if needed, and returns a generic internal server error response.

Parameters:

• next http.Handler: The next handler in the chain to invoke after this middleware.

Returns:

• An http.Handler that wraps around the original handler and adds recovery functionality for panics.

Example Usage:

http.Handle("/", RecoveryMiddleware(http.HandlerFunc(someHandler)))

4. AuthMiddleware

A middleware function used for basic authentication, ensuring that incoming requests have a valid authorization token in their headers.

Parameters:

• next http.Handler: The next handler in the chain to invoke after this middleware.

Returns:

• An http.Handler that wraps around the original handler and adds basic authentication functionality.

Example Usage:

http.Handle("/", AuthMiddleware(http.HandlerFunc(someHandler)))

Notes:

• RecoveryMiddleware: It catches any panics that occur in subsequent middleware or handlers and logs them along with stack traces. It also triggers an alert using github.com/Miskamyasa/utils/alerts package's Send function and returns an internal server error (HTTP status code 500) to the client.

• AuthMiddleware: This middleware checks for a specific authorization token in the request headers (auth-token). If the token does not match the configured AUTH_TOKEN, it logs an unauthorized access attempt and sends back an internal server error response.

Requirements:

• Ensure that you have the necessary environment variables set up, such as the AUTH_TOKEN required by the AuthMiddleware.

• The middleware functions assume the existence of a caching system (github.com/Miskamyasa/utils/cache) and alerting utility (github.com/Miskamyasa/utils/alerts) packages.
