express-clr

express-clr is the runtime implementation for Express-style APIs on ASP.NET Core.

It is the source of truth for behavior and parity decisions. The express repo publishes the generated TypeScript package that targets this runtime.

Scope

  • Express 5.x-oriented API surface.
  • ASP.NET Core primitives for server/request/response internals.
  • Pragmatic parity: maximize behavioral compatibility while documenting remaining deviations.

Quick Start

using express;

var app = express.create();

app.get("/", (Request _, Response res) =>
{
    res.send("hello");
});

app.listen(3000);

Build

dotnet build src/express/express.csproj -c Release

NativeAOT Validation

express-clr is designed for NativeAOT-first usage on ASP.NET Core primitives.

Validation command:

dotnet publish src/express/express.csproj -c Release -r linux-x64 -p:PublishAot=true -warnaserror

Current runtime avoids DynamicInvoke and reflection-based System.Text.Json serialization/deserialization paths.

Test

dotnet test tests/express.Tests/express.Tests.csproj -c Release

Coverage Gate

npm run test:coverage

The coverage gate enforces line, branch, and method coverage at 100% for the express assembly.

Documentation Map

  • Runtime architecture: docs/architecture.md
  • Known compatibility deviations: docs/deviations.md
  • API test/coverage matrix: docs/test-matrix.md

Naming Notes

Some HTTP verbs require C#-safe identifiers:

  • lock_() maps to LOCK
  • m_search() maps to M-SEARCH

For exact-string verbs, use method("...").
