What I'm trying to do here is simple : I have and filter method called "search()" that is called on different action on my page.
I'd like to "spy" this method and then check if it was called with : cy.get('method').should('be.called')
But really, I don't understand how to reach the method, that is written in one of my component as vue method and spy on it. I've read the docs, but still can't understand how to do this.
Thanks in advance.
This did the trick for me:
mount(Component, opts)
cy.spy(Component.methods, 'method').as('method')
cy.get('#method').should('have.been.calledOnce')
Keystone remove method executeQuery what to use instead when I work with query?
you have to use keystone.executeGraphQL or when inside the access control or hooks you can do context.executeGraphQL
I have some method to generate random hexademical color. It will be used in very few (3 or 5) parts of the project. So I want to separate it from main code into some kind of Helper or smth else, and include it when needed (not globally).
I have 2 working ways to do this:
Using mixins. What I don't like is that when you read the code, you can't separate your own methods from methods of mixin.
Using plugins. What I don't like with that is that you have to write import Vue from 'vue' + Vue.use(MyPlugin) every time in all files where you want to use it. After that, you can call it like this.$ColorHelper.getRandomHEX().
So, the question is about aesthetics visualization.
What is the best practices to do such things?
PS: project was created from template with webpack.
Our team decide use function import from files-helpers
For example:
import { getRandomColor, getBackgroundColor } from 'Global/helpers/colorHelper';
// .....
let color = getRandomColor();
What good:
Don't need use excess import + use as in plugins
Method visually stands out, what it not from this
What bad:
Cant see visually what the helper have method. But possible can fixed with aliases. We dont think yet
Vue plugins are global, you only have to call the Vue.use method once. Then they should work wherever you use that particular Vue instance.
In a default project setup you normally don't have multiple Vue instance so it should work globally.
From the docs:
Plugins usually add global-level functionality to Vue.
And:
Use plugins by calling the Vue.use() global method:
Vue.use(MyPlugin)

Is there a way how to run my own function before a dojo method is spawned?
Specifically I need to refresh data in dojo.store.Memory before query() function is spawned. My idea is to put there a callback (that will be spawned before query()), fetch new data from server and then set the data to Memory instance. Then just call
this.inherited(arguments)
I've tried override query method with declare, but I'm still getting some unrelated errors. 4 hours but no luck...
Is there a another way?
Thanks
Yes, you can fire callbacks before, after or around any method. Just use dojo/aspect
Something like this should work :
require(["dojo/store/Memory", "dojo/aspect"], function(Memory, aspect){
aspect.before(Memory, "query", function(){
// do something
});
});
However, for your specific use case, if I understood correctly, what you want is to have a store linked to a server-side controller. In that case, you should use dojo/store/JsonRest rather than dojo/store/Memory. No need to fire any methods before the query...
I want to implement a listener/observer for my XPCOM component, so my javascript code can register to be notified of some events. Is it possible?
If I understand you correctly https://developer.mozilla.org/en/Creating_JavaScript_callbacks_in_components might be just the thing you are looking for.
