Name	Type	Description

mode	string|string[]	See: Runtime Environments and Flavors
instanceName	string|string[]	See: Multi-Instance/Multi-Tenancy
host	string|string[]	Host

• General usage:

import { Aspect } from 'vona-module-a-aspect';

@Aspect.middlewareGlobal('a-core:gate', {
  gate: {
    flavor: 'normal',
    mode: 'dev',
    instanceName: '',
    host: 'localhost:7102',
  },
})

• Shorthand:

import { Core } from 'vona-module-a-core';

@Core.gate({
  gate: {
    flavor: 'normal',
    mode: 'dev',
    instanceName: '',
    host: 'localhost:7102',
  },
})

• Shorthand principle:

@Core.gate still calls @Aspect.middlewareGlobal internally, the code is as follows:

function Gate(
  options?: Partial<TypeUseOnionOmitOptionsGlobal<IMiddlewareOptionsGate>>,
): ClassDecorator & MethodDecorator {
  return Aspect.middlewareGlobal('a-core:gate', options);
}
