How to lazy load a js file in React (for a multilingual app)

纵饮孤独 提交于 2019-12-05 18:33:25
I would like to create a multilingual app with React. The way I see it would be to have a js file for each language, for example : en.js: module.exports = { langEnglish: 'English', langFrench: 'French', navHome: 'Home', navUsers: 'Users', ... }; fr.js: module.exports = { langEnglish: 'Anglais', langFrench: 'Français', navHome: 'Accueil', navUsers: 'Utilisateurs', ... }; As each language file will be quite big and there could be dozens of different languages supported, I would prefer to download only the correct file to use depending on the language chosen in order to minimize loading time (and

How to handle error in Primefaces lazy load?

隐身守侯 提交于 2019-12-05 16:40:25
I have problem to let user know about exceptions occurred in PrimeFaces LazyDataModel#load method. I am loading there data from database and when an exception is raised, I have no idea how to inform the user about it. I tried to add FacesMessage to FacesContext , but message is not shown on the Growl component, even if Growl is set to autoUpdate="true" . Using PrimeFaces 3.3 . It doesn't work because load() method is invoked during Render Response phase (you can check this by printing FacesContext.getCurrentInstance().getCurrentPhaseId() ), when all messages have already been processed.

Delay loading expensive fields in Entity Framework v.1

After hunting around the net, and thinking I'd come up with the solution, I seem to have hit another brick wall. I have a table in my database: Photos; containing columns for PhotoID, Caption, Ordering, and four sets of binary data: Original, Large, Medium and Small (yes, it was based on the old ASP.NET starter kit with various fixes, etc). I'm in the process of moving from L2S to Entity Framework for some of the advantages I appear to get with that - so I no longer need to go through a PhotosTags property to get the list of Tags attached to a photo for example, but I'm looking for a way to

Angular - Lazy loading a module inside module with a child route

倖福魔咒の 提交于 2019-12-05 14:33:04
I have an angular application where my main routing module lazy loads modules correctly. I do however now have an additional requirement of displaying another component / module inside one of the lazy loaded modules. When I now navigate to users/id (this part works correctly) I want a tab view in the HTML where I can load additional modules based on what tab is clicked on. For example, I might have 3 buttons: User Albums , User Favourites and User Stats . When I click on one of those, I want a component to display on the same page as a child using the <router-outlet></router-outlet> App

How to produce a lazy sequence by portion in clojure?

折月煮酒 提交于 2019-12-05 12:12:05
I have a database server and I fetch data from it. Sometimes data have millions rows and more so I use laziness for downloading. I use Server Side Cursors from clojure.jdbc library https://funcool.github.io/clojure.jdbc/latest/#cursor-queries to fetch data lazily. Now I have a problem. I need produce initial 500 elements from a lazy-sequence, then the program must wait for 10 minutes to get a signal which report to the program produce next 500 elements and so on until i receive all data from server. But if a report didn`t arrive for 10 minutes, the program must close a connection. I wrote
