Last time I work with Node and Vue.js. It’s very nice and allows to simplify many, many things. And it’s a lot better – for me – than React and its code mess… One of very nice features from Vue is components. We can separate code into small modules and then import and use them in another as blocks. We can also send some data to them, but direct data binding is only in one way – from parents to childs. According to official documentation, we should use events to notify parents about changes in childs and then make changes. But what about nested childs?
