A library, which is exported declaratively, could be loaded in a few straightforward steps. But what will happen when we import this method like that way in another file? Will it be loaded twice? Basically, ES6 Modules are singletons. So, if a module is imported multiple times, we can be sure it will be evaluated and loaded into the bundle only once.

ES6 Modules are a superb way to use third-party libraries. However, not all the third-party libraries support it, such as jQueryBootstrap and more. Note: We use typings modules for getting the desired autocomplete functionality in the IDE.

As an additional step, we open tsconfig. Then, we should add jQuery and Bootstrap to the types array so the TypeScript compiler will recognize those:. The first step will be to open to the. Now, we should look for the injected scripts array and add the relevant files of jQuery, Popper.

Just like that, the styles are injected as link tags. So far we examined adding of third-party libraries using ES6 Modules and global sources. Our mission now is to add a third-party library that includes some additional resources. Iconic is a perfect choice. Like before, we should navigate to. But, suppose we want to inject all the SVGs which are provided by that third-party - by now, we injected each file specifically.

So, how should we do that?Learn Development at Frontend Masters.

The web is full of third-party scripts. Sites use them for ads, analytics, retargeting, and more. Scripts can track your behavior, your preferences, and other information.

Documentation from GoogleFacebookand Wikipediatells us directly that these scripts can track behavior, sites visited, purchase history, demographics, IP address, location, and more. That part is generally known. That means eavesdroppers can track things like your email, username, full name, home address, purchases, location, history, IP address, and preferences. Just by clicking around the web, you can unknowingly allow someone to build up a huge profile of information about you.

They encrypt each address after receiving it, but it still gets sent as plain text, so the damage is done. This allows attackers to inject any code they want, including code that can steal credit card numbers.

Many of the advertisers have since fixed the vulnerability, but that leaves open the question of what other exploits are still out there. Many tracking scripts in the wild use regular non-secure HTTP. My colleague Brent Kimmel told me about a technique called subresource integritywhich essentially lets you make sure you get what you expect.

Third-party scripts frequently cause pages to load slower. The following screenshot shows the tail end of a long line of third-party scripts numbering in the hundreds:. When a script uses document. A lot of common third-party scripts use document. Third-party scripts often perform operations on the scroll event. Some of the most widely used third-party scripts on the web use unnecessary global variables which can overwrite the variables on your site.

The following screenshot shows a script using two global variables to generate one random number even using an unnecessary type conversion in the process. Interestingly enough, the function is actually called arbitraryJSCode.Last week we've learnt the hard way in production about critical rendering path and its friends in modern web browsers. An external host providing analytics script was very slow to respond.

Unfortunately, the third-party script was blocking the load of all the further resources of the page. Hence it took around 70 seconds to load the login page although our own servers were working fine! If you fail to provide the async flag, the script in synchronous; the browser can't proceed with rendering and any JavaScript execution until the sync script is loaded executed since perhaps the script may want to use document.

Our analytics script was loaded this way. We would display a splash screen without waiting for the script to load, but the actual app load took much more time. This is because If you're a JavaScript-heavy single-page application, the next important thing is the event you use to boot your app. It is usually fired pretty fast in the lifetime of the app. On the other hand, load is only fired when all the resources images, stylesheets etc. This means a single slow image or script can slow down the load event by an order of magnitude.

DOMContentLoaded is not raised in IE8- but you can work around it via a bit more complex readystatechange observation. In a web dev slang, you may hear a script with async flag to be called non-blocking, but they're not blocking only the construction of the DOM tree i.

DOMContentLoaded event. But they're still blocking the load event. Unfortunately we were doing just that: using window. In normal circumstances, the difference was negligible, but today it his us hard. Actually, in our case, we were loading an external script via JS, using script. However, no amount of async can save you if you're waiting for load event! If you're on Windows, you should already know Fiddler.Learn Development at Frontend Masters. At Wufoo, we just switched over to an asynchronous embed snippet.

Users who build forms with Wufoo and want to embed them on their site are now recommended to use it. We did it for exactly those reasons above. This definitely slows down page loads, especially if the script is in the head or above any other visual elements. IE 6 and 7 do this, only allowing one script to be downloaded at a time and nothing else. IE 8 and Safari 4 allow multiple scripts to download in parallel, but block any other resources reference.

Ideally we fight against both of these problems and speed up page loading both actual and perceived speed. There is an async attribute for the script tag in HTML5 spec. The browser support for it is Firefox 3. No Opera support yet. If you are going to load a script directly like that, using this attribute is probably a good idea. It prevents parser blocking. BuySellAds is an advertising network that was one of the first to deliver ads asynchronously. This is their pattern:.

Sometimes you need to load a third-party script, then once that script is loaded, fire off some custom code. That custom code probably calls some function defined in the third-party script with data that is unique to a specific page. Typekit is in this situation. You need to load the Typekit JavaScript, then kick it off.

Typekit is actually taking advantage of the fact that scripts block the parser. There is an awful lot of gnarly code there to handle the onload callback.

Be forewarned, using this pattern actually brings back the problem of FOUT. If you want to go async with Typekit and have just as good an experience as you do normally, read their post on it which covers some clever class name manipulation and font events.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

My company makes a JavaScript widget that e-commerce sites can embed on their pages. Our current instructions to our customers tell them to load our JS on every page of their site and most follow this advice to the letter, even including it on their pages with credit card forms. I have been petitioning for us to change the instructions to "load on every page except the one with the credit card form", but I have not yet been successful. My company's primary concern is that our customers will put us through extra scrutiny or otherwise conclude that our product is insecure and that we will loose business as a result of this.

They also do not believe that there is a significant risk in having our JS on the credit card page. But it was met with the same opposition as before. There were also concerns about what if the url changed or how to handle situations where we can't tell if it's a CC page or not from the URL.

We have at least one customer where this is the case. So my original request still stands. Facts : Are there any examples of business that have been compromised this way? What was the outcome?

Perception : What can we share with our customers to counter the idea that being concerned about security indicates we're less secure? Most ecommerce sites include google analytics code on payment pages. There are also integrations to third-party product subscription engines that rely on JS passing CC data from the cart back to the service's mother ship e.

Ordergroove via https. Many ecommerce platforms make it easy to include a widget on all pages via a templating system, but difficult to exclude just a single page in the conversion funnel. One option might be to wrap your widget in a bit of JS that ends up NOT including your remote code in instances where the URL matches a specific pattern. This would allow your customers to place the code everywhere in all templateswhile easily preventing the execution of your code on specific pages.

This could be delivered as alternate installation instructions. If I understand correctly, you are trying to proactively protect your clients from the perception of potential risks by suggesting that your own code should not be run on certain pages. Your efforts might not be necessary. Let your clients protect themselves by letting them choose for themselves. Alter your documentation to say, "install on every page, but pages with CC process may be safely omitted.

Is there a way to hack your JS Widget in such a way as to pose a threat if the widget and customer credit card data are on the same page?

You'd need to really review the widget, and how it can be compromised - it's more of a design question than a blanket rule. In terms of compromise examples - they are always few and far between - unless they are notorious, most companies don't publicize them.

Your best bet is to check for OWASP guidance and the vulnerability publication sites to see if there's any particular JS alerts connected to anything in your widget.

In terms of rules to live by - common best practice is to keep your implementations and interfaces simple, clear and subject them to careful review. Putting the JS widget in places it's not needed may violate that premise by adding unnecessary complexity.
