errorcore
Middleware

Koa

Koa integration is best handled in the outer middleware layer. That gives errorcore one async boundary around the request and one consistent place to attach request metadata.

koa middleware
app.use(async (ctx, next) => {
  return errorcore.withRequestContext(
    {
      method: ctx.method,
      route: ctx.path,
      requestId: ctx.get("x-request-id"),
    },
    async () => {
      try {
        await next();
      } catch (error) {
        errorcore.captureError(error);
        throw error;
      }
    },
  );
});

Keep the wrapper near the top of the stack so downstream middleware inherits the same request scope.

Fastify

Use Fastify hooks to attach request context and capture failures without duplicating reports.

Hapi

Attach request metadata through lifecycle extensions and capture failures in the shared request path.
