Castle Windsor lazy load services

阅读更多关于 Castle Windsor lazy load services

问题 Occasionally I find myself in a situation where I need to resolve a service only if a certain condition is met. For example, a user might select to send an email or an sms notification. I would like to lazy load the email or sms service depending on what the user chooses so that I don't have to load both of them and waste resources (what if there were, for example, 10 options for the user...?). The problem I have is with using the container outside of my bootstrap code (I dont want my code

问题 I'm using require.ensure to create split points at react-router paths. However, my build directory still only has app.js in addition to the vendor.js . I was expecting a separate js file for each path I used require.ensure . I used require.ensure at each path like this: <Route path= 'auth' getComponent={(nextState, callback) => { require.ensure([], (require) => { callback(null, require('containers/Authenticate/AuthenticateContainer.js').default) }, 'auth') }}/> my web pack config output for

I'm trying to create a default route using the wildcard '**' from Angular's router. That default route will load a lazy module and then it will have to solve its own routes. The problem is that when I have the following configuration it does not resolve as expected: export const routes = [ { path: '', component: 'DashboardComponent' }, { path: '**', loadChildren: './lazy/lazy.module#LazyModule' } ]; @NgModule({ imports: [ BrowserModule, RouterModule.forRoot(routes) ], declarations: [AppComponent] bootstrap: [AppComponent] }) export class AppModule {} const routes = [ { path: '', component:

IRepository Aggregates and Lazy Loading

阅读更多关于 IRepository Aggregates and Lazy Loading

问题 I've been trawling stackoverflow and the internet in general all day about the IRepository pattern trying to better understand it before I try and use it in anger. From what I've read (and please do correct me if I'm mistaken) a repoistory encapsulates access to its aggregate root and child objects exposing a common interface that can then be injected or mocked. So in the instance where you have your aggregate root object: class Employee { string FirstName; string LastName; IEnumerable

问题 Scenario: I have some angular modules like: angular.module('app', ['app.core', 'app.views']); // not lazy load Each module under app.views uses a RouterUtil to register their own route, like: $stateProvider.state('state name', {/* some configs here */}); This RouterUtil also have a method to access all registered states (used to create a dynamic menu). And I'm using the ocLazyLoad, just to load an external module. When the page is loading, ocLazyLoad will perform a request to other js with

Jquery LazyLoad.js Issue with Loading after Window Resize

阅读更多关于 Jquery LazyLoad.js Issue with Loading after Window Resize

问题 Im running the LazyLoad script for my website and having an issue with one small aspect of it. Im using Lazy Load on a Horizontal scroll (left to right) with fairly wide images. The script works perfectly and fades in within 200px (or whatever the default is). However I noticed if the window is opened to a smaller size, then opened to full window, the placeholder, Lazy Load has only the image loaded that was "In View" during the smaller window size. It loads once the scroll bar is moved, but

问题 The design I've been given to work with is 960px wide by around 7000px tall, cut into five vertically-stacked segments at arbitrary points. There's a fixed-placed sidebar that scrolls to each segment, depending on which navigation link is clicked. Atop this are a bunch of sliders, transparent PNGs, headlines and paragraphs, predominantly positioned in a relative fashion. I need to ultimately do two things: Hide the corresponding quick-nav links in the sidebar until its related segment's
