What is the best way to distribute reusable JavaScript modules with dependencies? -


There are several ways to format the JavaScript module: AMD, CommonJS, UMD, ES6, Global Script I saw those projects All the sources that structure their source code and run a build process to create a dist directory with code in all the above formats. The advantage of this is that whatever format the user of the code can choose, is most applicable to his environment.

This method works fine as long as the module does not have any dependencies on other modules. In cases where the modules should import other modules, there are implicit complications. For example, RequireJS uses a config file that looks like this: 

  requirejs.config ({path: {'jquery': 'js / lib / jquery', 'ember': 'Js / lib / amber', 'handlers': 'js / lib / handlar', 'underscores': 'js / lib / underscore'}});

Other loaders have similar mechanisms for mapping the import paths.

If jQuery is a dependency, should it import the module from the 'jquery' path? What if the system on which it is being stored on store 'Libs / Jquery'? In this case, is it the responsibility of the author of the system, in which jQuery can be included to provide the nickname in the configuration of the import path?

This question strongly suggests that in reality the reusable modules should be formatted in all modules, clearly defined formats and documents, which libraries (and its versions) What is the basis and what are the documents on which the existence of those libraries is considered.

For example, I can write a fancy jQuery plugin, which I distribute, AMD, CommonJS, ES6 and global variations I document that this plugin is imported through 'jquery_on_a_path_that_confuses_you' JQuery version depends on version 2.0. The user using this plugin will have to copy the plugin into its project and then configure your module loader or create tools to export jQuery to 'jquery_on_a_path_that_confuses_you'.

As far as I can tell:

  • There is no standard for what to use for import paths.
  • There is no standard way to express the dependencies, versions, and import path requirements for the user of one piece code.
  • There is no standard solution to struggle with import paths or to load multiple versions of the library.

Is there any plan to deal with this weird system? For me this is a module system that does not know the name of its module, am I wrong?

You can check that there is a relatively new package manager and universal module loader

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date (). GetTime (); For (var i = 0; i & lt; 1e7; i ++) {if ((new date). GetTime () - start) & gt; Milliseconds {break; CSS ('font-size', 'parseInt ($ (' game-title '). CSS (' font-size ')) + 1 + "pixels"); } While (parasont ($ ('# text'). Css ('font-size')) & lt; = 100) {sleep (1000); IncreaseSize (); Using CSS: Use of jQuery (sample):
