JSZip VS webpack

You can use a lib named JSZip : https://stuk.github.io/jszip/ You can add binary data (your audio slice) inside a zip like that

The ZIP file functionality was implemented using jszip - I'd originally wanted to download the files directly to a folder on the user's filesystem (coming from a scripting background) but turns out unrestricted filesystem access like that isn't something that browsers can do (at least from my limited research).

So to summarize, you need to use a NPM module that handles writing ZIP files, like jszip, but you also should learn about how the Node.js event loop works, and how asynchronous I/O routines run in the background, while your program continues its own execution without waiting.

I use JSZip (https://stuk.github.io/jszip/) to parse EPUB files

Your site went down for maintenance in the middle of my exploring, but here's some feedback so far. 1) The exports (CSV, PDF, etc) should probably include my username and Banano address. Right now there doesn't appear to be any indication of who a downloaded report is tied to. 2) Why do you let me download the database, including column names? If I was an attacker, I could use this to understand your DB layout and possibly do a SQL injection attack. I'd recommend masking the names somehow. 3) I did a quick review of the Github: a) jQuery 3.6.0 has a more recent version, 3.6.1 - https://blog.jquery.com/2022/08/26/jquery-3-6-1-maintenance-release/ b) In /history, you use JSZip 3.1.3, which has a known denial-of-service vulnerability that could take your site offline. This should be upgraded to 3.10.1 - https://stuk.github.io/jszip/

It uses other utility libraries like Lodash, JSZip and SortableJS. JSZip is used to package the user interface markup into HTML files and other required JavaScript files for a Marketplace App boilerplate in a compressed format and download them from the browser.

JSZip - JSZip is a javascript library for creating, reading and editing .zip files, with a lovely and simple API.

Another operation that is sometimes desired is to take several files and give the user a compressed file. There are actually a surprisingly large amount (jszip, pako) of client side options here, but my favorite so far when it comes to speed, size and working with .zip has been fflate. But if you'd like to work with other formats, there are also libraries to decompress 7-Zip, RAR & TAR.

There are various tools available that manage the size of bundled assets. We are going to use the example of a popular and widely used bundler named Webpack, and practically look at many of the optimization techniques it offers.

Click "Start Test." WebPageTest generates a comprehensive report with details about the loading process, including time to first byte (TTFB), page load time, and visual progress. ### Setting Benchmarks with Lighthouse Start with Lighthouse audits to maximize the performance of your React application. Evaluate Lighthouse's scores and suggestions with careful consideration. Next, set benchmarks that are in line with industry norms or customized to meet your unique performance goals. Lastly, pay close attention to the places in your application where it needs work. You can improve your React application's effectiveness by carefully following these procedures, which will guarantee that it satisfies the required performance requirements. ### Analyzing Performance Results with WebPageTest In order to fully evaluate your webpage's performance, launch WebPageTest with a variety of systems, simulating a variety of user scenarios. Examine the waterfall chart carefully to identify loading patterns and bottlenecks, which are essential for improving the user experience. To see the page's rendering process over time and do a thorough examination, use filmstrip views. To effectively assess performance, pay special attention to measures such as time to first byte (TTFB), start render time, and fully loaded time. Also, a better understanding of performance variances is made possible by comparing findings across various test designs, which helps make well-informed recommendations for improving webpage responsiveness and efficiency. ## Impact of third-party libraries on React app performance Third-party library integration can speed up development while improving functionality in our React application. It's crucial to consider the possible effects on performance, though. Because heavy or poorly optimized libraries might negatively impact the speed and usability of our application. ### Bundle Size Look at the distribution file sizes related to the library, and use tools such as Bundlephobia or Webpack Bundle Analyzer to fully evaluate their impact on your bundle size. This thorough analysis enables you to make well-informed decisions about whether to include the library, making sure that its contribution minimizes superfluous bulk in your application's codebase and is in line with your optimization goals. ### Network Requests Analyze how the third-party library affects network requests to maximize performance. Reduce the number of requests made overall by minimizing external dependencies. This will enhance the user experience and loading speeds. Select appropriate libraries, maximize asset delivery, and leverage code splitting to load components asynchronously. You may improve the effectiveness and responsiveness of your application and provide users with a better experience by cutting down on pointless network queries. ### Execution Time Examine the library's code for any possible performance problems or bottlenecks in order to analyze the runtime performance of the library. Look for places where the code may execute slowly or inefficiently. You may ensure smoother operation inside your application by identifying and addressing any areas of the library's implementation that may be impeding ideal performance by doing a comprehensive assessment. ### Code Splitting for Third-Party Libraries Implementing code splitting is an effective strategy to load third-party libraries only when they are required, reducing the initial page load time. Use dynamic imports to load the library lazily:

Thanks for the thorough answer!

I confess I wasn't thinking about a particular build tool. My recent experience has been with Vite, where I took a similar approach to what you describe, but haven't had to dig deep into bundle performance because that's not a bottleneck for our application. The last time I did deeper work on the subject was years ago with Webpack.

I thought Webpack at least did dead-code elimination before splitting things into chunks. If I'm reading this random GitHub issue[1] right (and the asker is also right), Webpack does partially behave as I expected, but the pre-chunking optimization pass occurs before things like constant expression evaluation.

Webpack is a powerful and widely-used module bundler for JavaScript applications. It’s known for its flexibility and extensive plugin system, making it a popular tool in complex web development projects.

Thats all about Webpack Basic, there are lots of feature of webpack, You can check here: https://webpack.js.org/

Many web pages use CSS and JavaScript files to handle various features and styles. Each file, however, requires a separate HTTP request, which can slow down page loading. Concatenation comes into play here. It involves combining multiple CSS or JavaScript files into a single file. As a result, pages load faster, reducing the time spent requesting individual files. Gulp, Grunt, and Webpack are some of the tools that can assist you in speeding up the concatenation process. They enable seamless merging of many files during development, ensuring deployment readiness.

Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.

Webpack is a module bundler, the main purpose of which is to bundle JavaScript files to make them usable in a browser.
