## What it is
Edge.js is an interop library that lets Node.js and .NET (CLR, .NET Core, Mono) code call each other in-process, on Windows, macOS, and Linux. It supports scripting C# (and other .NET languages) from JavaScript and vice versa via an async calling convention. Note: this original repo is superseded by the actively maintained agracio/edge-js fork.

## Use cases
- call C# code from a Node.js application
- run Node.js scripts from a .NET application
- reuse existing .NET libraries in a JavaScript project
- combine Node.js I/O handling with CPU-bound .NET processing in one process
- bridge JavaScript and .NET ecosystems without separate services

## When to choose
- you need tight in-process interop between Node.js and .NET rather than an HTTP or IPC bridge
- you want to call legacy .NET libraries from Node.js or vice versa
- you need cross-platform (Windows/macOS/Linux) CLR-Node interop

## When to avoid
- you want an actively maintained project - use the agracio/edge-js fork instead
- a lightweight out-of-process bridge (REST, gRPC, message queue) fits your architecture better
- you are not mixing Node.js and .NET ecosystems
