JSON Schema code generation and ultra-fast validation, for .NET and eight more languages.
Strongly-typed C# from every feature of JSON Schema, draft 4 to 2020-12 and OpenAPI, plus one evaluator with the same results in .NET, JavaScript and TypeScript, Rust, Python, C, C++, Swift, Ruby and PHP.
ECMA-262 regular expressions for .NET and fourteen more languages: the answers of ECMAScript, over UTF-8 and UTF-16.
The grammar and semantics of ECMAScript 2025 with every flag, held to V8's answers on the ECMA-262 test data with none wrong: in the shape of System.Text.RegularExpressions with a source generator for .NET, and for C, C++, Fortran, Go, Java, Julia, Object Pascal, OCaml, PHP, Python, R, Ruby, Rust and Swift.
Every Corvus ECMA-262 regex engine on one page, beside each platform's own regex engines and V8.
The Industry workloads of dotnet/performance, run nightly by each engine's repository and gathered daily into one page, with each engine's result on the ECMA-262 test data beside its name.
Low-allocation URI Template parsing and resolution, supporting the Tavis.UriTemplates API
This is a netstandard2.0 and net8.0+ implementation of the URI Template Spec RFC6570. The library implements Level 4 compliance and is tested against test cases from UriTemplate test suite.
A zero allocation globbing library.
We built this to provide a zero-allocation globbing library with performance comparable to (or better than) https://github.com/dazinator/DotNet.Glob and raw Regular Expressions, when running under net6.0.
A library of Python utility functions and classes
Many components have been designed to help streamline local development of cloud-based solutions.
This provides a library of useful testing extensions, primarily focussed on SpecFlow operations.
It is built for .NET 6.0, and we support use on both .NET 6.0 and .NET 8.0. (If you require .NET Standard 2.0, use Corvus.Testing v1.)
