📝 [Proposal]: Make fiber.Ctx implement context.Context

Feature Proposal Description

Having multiple types of contexts in Go can be confusing, especially for developers transitioning from other languages. This proposal aims to simplify the context handling in Fiber by making fiber.Ctx implement the context.Context interface.

Why not just make fiber.Ctx implement context.Context?

In Go, the context.Context interface is a standard way to handle context in various packages. Implementing this interface in fiber.Ctx would allow developers to use the same context handling mechanisms across different packages, making it easier to write and maintain code.

The context.Context interface provides a set of methods for handling context, including:

type context.Context interface {
	Deadline() (deadline time.Time, ok bool)
	Done() <-chan struct{}
	Err() error
	Value(key any)any
}

By implementing this interface in fiber.Ctx, we can leverage the existing context handling mechanisms in Go and provide a more consistent and predictable experience for developers.

Alignment with Express API

Fiber is a popular Go web framework that aims to provide a similar experience to Express.js. However, in this proposal, we are not aligning with the Express API, as the context handling mechanisms in Fiber are different from those in Express.

HTTP RFC Standards Compliance

This proposal does not involve any changes to the HTTP RFC standards compliance of Fiber.

API Stability

Making fiber.Ctx implement context.Context would not be backward compatible with v2, as it would require changes to the existing API.

Feature Examples

// Create a new context
ctx := context.Background()

// Get the deadline from the context
deadline, ok := ctx.Deadline()
if !ok {
    // Handle the case where the deadline is not set
}

// Get the error from the context
err := ctx.Err()
if err != nil {
    // Handle the error
}

// Get the value from the context
value := ctx.Value("key")
if value != nil {
    // Use the value
}

Benefits

Implementing context.Context in fiber.Ctx would provide several benefits, including:

Simplified context handling: By using the same context handling mechanisms across different packages, developers can write and maintain code more easily.
Improved consistency: Implementing context.Context in fiber.Ctx would provide a more consistent and predictable experience for developers.
Better integration with other packages: By using the same context handling mechanisms, Fiber can better integrate with other packages that use context.Context.

Drawbacks

There are no significant drawbacks to implementing context.Context in fiber.Ctx. However, it would require changes to the existing API, which may break backward compatibility with v2.

Alternatives

There are no alternative solutions that would achieve the same benefits as implementing context.Context in fiber.Ctx. However, developers could use the context.Context interface directly in their code, which would require more boilerplate code and may not provide the same level of consistency and predictability.

Conclusion

Implementing context.Context in fiber.Ctx would provide several benefits, including simplified context handling, improved consistency, and better integration with other packages. While it would require changes to the existing API, which may break backward compatibility with v2, the benefits outweigh the drawbacks. Therefore, we propose making fiber.Ctx implement context.Context.
