Is there a way to lazy load components, not modules, in Angular?

由 孤街醉人 提交于 2019-12-09 14:29:29
问题 Lazy loading is a commonly used technique. However, in Angular it seems that the granularity level of this technique stops at the module level. That means that you can have module main that loads in the browser, and then on special occasion module B and C and D can be loaded lazily. Almost all tutorials on web explain that. However, is there a way to load components lazily? Consider this simple example that user goes inside the application, and when clicks "invoices" link, URL changes to the

How to get the current MavenSession or MavenExecutionRequest from a Plexus Component

由 佐手、 提交于 2019-12-09 07:23:08
问题 I created a Plexus component to house common logic for several Mojos I want to create. I have been able to pass information like localRepository and project from the Mojo (and test cases). I was wondering if there is a way to get the MavenSession or MavenExecutionRequest from within the component without having to pass them as parameters from a Mojo. I know my component will be running from a Maven Mojo. I'm using Maven 2 in this instance. 回答1: I don't believe there is, nor would I think it's

问题 Can someone explain in what's the difference between elements marked in diagram? I think it only depends on how many interfaces we want to connect. Am I right? http://i.imgur.com/ZnW02Ar.png 回答1: You are not right and the diagram is syntactically incorrect. Let me first explain the concepts and their meaning: Dependency between components exist on the definition level (top part of the diagram). They can be drawn between the required and provided interface, between a component and interface or

Load NgModule entryComponents dynamically using service

问题 Hi I am new to angular2 and typescript. I am loading components dynamically and I was wondering if there is a way to declare my components using a service in the module's "declarations" and "entryComponents". Using typescript, I am able to achieve it by doing the following: import { ComponentLoaderService } from './../../services/component-loader.service'; let componentsToLoad = ComponentLoaderService.getComponents(); @NgModule({ declarations: [ componentsToLoad ], entryComponents: [

问题 I want to create a simple form builder with Vue where users click on buttons from a menu to add different form fields to a form.

React, get bound parent dom element name within component

由 点点圈 提交于 2019-12-09 04:13:16
问题 Within my component, how can I access the name of the parent component it is nested inside? So if my render is thus: ReactDOM.render( <RadialsDisplay data={imagedata}/>, document.getElementById('radials-1') ); How can I retrieve the id name #radials-1 from within the component itself? 回答1: It probably makes the most sense to pass it as a property, but if you really need to get it programmatically, and from inside the component, you can wait for the component to mount, find its DOM node, and

Windows System Tray icons - controlling position

由 落花浮王杯 提交于 2019-12-09 01:38:18
问题 I have a few old apps I've written (in Delphi) which for various reasons use a system tray icon. Most are using AppControls TacTrayIcon or some other similar component. Here's my question: How does one control the position of a tray icon? (i.e. where it is, say, relative to the system time -- 1st position/"slot", 2nd position/"slot", etc). I recall seeing a demo (C#, if memory serves) that allowed the user to "shift icon to the left" and "shift icon to the right", but don't recall how it was
