Universal, extensible and improved JS API for Chats, like TawkTo, Jivochat, and others.

import ChatBase from './ChatBase'

export function jsApiMethod() {
  return function(
    target: ChatBase<any>,
    prop: string,
    descriptor: PropertyDescriptor
  ) {
    const originalMethod = descriptor.value

    descriptor.value = function(this: ChatBase<any>, ...args: any[]) {
      if (this.loaded) return originalMethod.apply(this, args)
      if (prop.startsWith('is')) return false
      if (prop == 'state') return ''
      if (prop == 'visitorData') return {}
      return new Promise(resolve => {
        this.on('load', () => resolve(originalMethod.apply(this, args)))
      })
    }

    return descriptor
  }
}
