Corvus.Text.Json

High-performance JSON library for .NET that builds on the patterns of System.Text.Json with:

  • Source-generated types from JSON Schema (draft 4, 6, 7, 2019-09, 2020-12)
  • Pooled-memory parsing via ParsedJsonDocument<T> — just 136B per-document allocation (91% less than JsonNode)
  • Mutable document building via JsonDocumentBuilder<T> and JsonWorkspace
  • Full schema validation with EvaluateSchema() — 10× faster than other .NET validators
  • Extended numeric types — BigNumber (arbitrary precision), BigInteger, Int128, Half
  • NodaTime integration — LocalDate, OffsetDateTime, OffsetTime, Period from JSON Schema formats
  • Pattern matching — type-safe Match() for oneOf/anyOf discriminated unions

Installation

dotnet add package Corvus.Text.Json

Quick Start

using Corvus.Text.Json;

// Parse JSON with pooled memory
using var doc = ParsedJsonDocument<JsonElement>.Parse(
    """{"name":"Alice","age":30}""");
JsonElement root = doc.RootElement;

string name = root.GetProperty("name").GetString();  // "Alice"
int age = root.GetProperty("age").GetInt32();         // 30

With Source-Generated Types

// Generate strongly-typed C# from JSON Schema
[JsonSchemaTypeGenerator("Schemas/person.json")]
public readonly partial struct Person;

// Parse, access, and validate
using var doc = ParsedJsonDocument<Person>.Parse(json);
Person person = doc.RootElement;
string name = (string)person.Name;
bool valid = person.EvaluateSchema();

// Mutate with the builder pattern
using JsonWorkspace workspace = JsonWorkspace.Create();
using var builder = person.CreateBuilder(workspace);
Person.Mutable root = builder.RootElement;
root.SetAge(31);
