This is a custom validator middleware for the Fiber web framework. It provides a flexible and extensible way to define and apply validation rules to incoming request bodies. The middleware allows for easy validation and sanitization of data, enforcement of specific field requirements, and ensures the integrity of the application's input.
The middleware currently supports the following features:
- Validation of request bodies in various formats, including JSON, XML, and other content types
- Customizable error handling based on content type
- Restriction of Unicode characters in specified fields
- Conditional validation skipping based on custom logic
- Restriction of fields to contain only numbers with an optional maximum value
- Restriction of string length for specified fields with a configurable maximum length
- Storing validation results in the request context for advanced use cases
More features and validation capabilities will be added in the future to enhance the middleware's functionality and cater to a wider range of validation scenarios.
Note
This repository will focus on maintaining and adding more features only for Fiber v2 for the following reasons:
- Fiber v2 is already stable
- It's easy to implement middleware features that are missing (since I am familiar with many Fiber 2 signatures) or other.

Based on the benchmark results, the following observations can be made:
- The Sonic JSON encoder/decoder consistently outperforms the standard JSON encoder/decoder in terms of execution time, bytes allocated, and allocations per operation.
- The custom XML encoder/decoder performs slightly slower than the default XML encoder/decoder in most cases, with similar memory usage.
- The JSON benchmarks generally have better performance compared to the XML benchmarks, with lower execution time, bytes allocated, and allocations per operation.
Overall, the benchmarks using the Sonic JSON encoder/decoder demonstrate the best performance among the tested scenarios.
