[英]How to declare javascript object with constructor in clojurescript
My code works with realm library and at some point it calls realm constructor: 我的代码与领域库一起使用,并在某些时候调用领域构造器:
(dependencies/realm. (clj->js options))
Realm was declared like this: Realm的声明如下:
(def realm (js/require "realm"))
Right now I want to temporarily mock realm object to not make calls to library. 现在,我想临时模拟领域对象,以不调用库。 I tried this approach:
我尝试了这种方法:
(def realm #js {:schemaVersion (fn [])
:close (fn [])})
It worked well for mocking close() and schemaVersion() functions but I'm getting error dependencies.realm is not a constructor
. 它对于模拟close()和schemaVersion()函数效果很好,但是我遇到了错误
dependencies.realm is not a constructor
。realm dependencies.realm is not a constructor
。
How can I add constructor declaration to realm object placeholder? 如何将构造函数声明添加到领域对象占位符?
Thanks. 谢谢。
In javascript a constructor is a function. 在javascript中,构造函数是一个函数。 Instead, you should have a function that returns an object:
相反,您应该具有一个返回对象的函数:
(def realm (fn [] #js {}))
I assume schemaVersion
and close
are static methods. 我假设
schemaVersion
和close
是静态方法。 You can add them later with: 您可以稍后添加它们:
(goog.object/extend realm #js {:schemaVersion (fn [])
:close (fn [])})
