If you want to load your entire javascript source for every page, sure, compile it into one file. You might not see any difference at all, if the compile time is outweighed by the number of HTTP requests you make.īut for overall applications which are tens (or hundreds) of thousands of lines long, where only a fraction of that functionality is needed on any one page, there can be big savings in terms of perceived time between when the page loads, and when the app is 'ready' for basic interaction by the user. then there's nothing at all wrong with doing what you're doing. The overall moral is, if you've got a system where all of your files are small, the overall weight of JS on the page is very small, you only needed a few hundred lines to do everything you wanted on the us, you know where all of your dependencies are, you have a system on the server to make sure they're in the right order, et cetera (plus you've got great documentation, or you're the only one who touches this code, and you live inside of it, day to day). If you just want it loaded and order isn't important, then you don't need to give it dependencies. If those dependencies have any dependencies, then they won't be initialized until their dependencies are loaded.

It allows you to declare dependencies up front, and hand in the code (as a callback) to be implemented, after all of its dependencies are handled. RequireJS uses a promise system, basically. Then extra functionality can be streamed in, either after the load and initialization, or just-in-time, as-requested by the user, and in both cases, as long as the code you've streamed in is focused on doing that one thing, and isn't calling for a half-dozen other dependencies, the time between the request and the addition of the functionality is going to be minimal.

The time required to add base-functionality to the page is lower. The overall number of HTTP connections used is higher.īut the time required to make the page visible to the user is lower. The overall time spent downloading is higher. If you've got a 20,000 line file, and you only need 600 of those lines to get everything up and running (assuming that everything is written to be modular and asynchronous, using any pattern at all for managing the resources), then you're going to save yourself what might be half a second or more, if you serve the core program and extend as-needed (or on a delayed timer, serving large chunks of functionality which are closely related to one another). Part of the issue with just concatenating the file isn't the time spent downloading, it's the time spent compiling on every page. (What exactly does require.js do? I cannot for the life of me read between the lines on their website.) Is there a way to make AMD and CJS play nicely, so that client JS files can be loaded asynchronously but still have CJS syntax? Thus, the only reason to use CJS in the client is to share code with the server.

AMD seems to be a better fit for the client. CJS is required for server-side loading (that's how Node.js works, if I'm not mistaken). The report was published by security research firm ZeroPeril.Why do I need to asynchrously load my JavaScript files in a web page? I can see the rationale for it on the server side, but if I know all the files I need to load in the client, why shouldn't I concatenate all my source files into 1 file and load that on page load? Is the first initial page load so important that future operations may be slowed down due to latency in retrieving every JS file?Īssuming the answer to question 1 is that I need to load JS files separately:ĪMD loads each JS file asynchrously, CommonJS loads synchronously. It's only supposed to be accessible to administrators, but the recently published report found that non-privileged users could leverage an exploit in the driver to gain access to the information. The PSP is an important part of the computer that works in conjunction with the OS to store sensitive data using secured memory sections. The vulnerability is in the Platform Security Processor (PSP) chipset driver and is tracked under CVE-2021-26333. The vulnerability impacts all Ryzen processors and several previous generations of AMD hardware. If attackers exploited the vulnerability, they could steal sensitive information from Ryzen computers, including passwords.

However, a recent report published by security researchers disclosed a significant vulnerability in the driver.

Last month, AMD launched a driver to patch a critical security flaw without mentioning which vulnerability the patch was meant to address. Anyone using a computer that runs AMD Ryzen hardware needs to apply the latest driver updates to secure their computer systems.
