It also explains the archive and manifest infrastructure used to serve files efficiently and outlines work to make crates.io usernames independent of GitHub accounts, enabling future support for other identity providers. ### Source excerpt Another six months have passed since our last development update, and the crates.io team has been busy. Here's a summary of the most notable changes and improvements made to crates.io since then. Source Code Viewer Crate pages now have a "Code" tab that lets you browse the contents of published crate versions directly on crates.io. This shows you the exact files that cargo downloads when you add a crate as a dependency, which might differ from the linked repository. This makes it much easier to audit your dependencies, including files that never appear in the repository, like the normalized Cargo.toml files that cargo generates. The viewer comes with a file tree sidebar with search functionality, syntax highlighting, and GitHub-style line selection, where clicking or dragging line numbers produces shareable #L10-L20 URLs. Under the hood, the server now builds a zip file for every published version. Since the .crate files that cargo consumes are gzipped tarballs without random access support, a background job re-packs each of them into a seekable zip archive plus a JSON manifest describing the contained files. Both are served from our static CDN. The frontend then fetches only the manifest and loads each file on demand with an HTTP range request. Because of this architecture, browsing crate sources essentially adds no load on the crates.io API servers. Existing crate versions have been backfilled, so this works for old releases too. The rendering library behind the code viewer is a diff renderer at heart, and that's no accident: a version-to-version diff viewer built on the same infrastructure is currently in the works. This will allow you to review exactly what changed between two published versions, right on crates.io. Stay tuned! Untangling crates.io Accounts from GitHub At the end of May, the crates.io team accepted RFC #3946. Crates.io accounts always have been tightly coupled to GitHub: signing in means "Log in with GitHub", and your crates.io identity is your ## Coding Challenge #125 - Online Diff Viewer DevFeed: [Coding Challenge #125 - Online Diff Viewer]() Original publisher: [Read original article]() Author: John Crickett Published: 2026-07-04T08:01:27Z Content type: tutorial Language: en Sources: [Coding Challenges]() Topics: [Code Challenge](), [coding](), [web applications](), [Algorithm](), [Accessibility](), [Syntax Highlighting](), [navigation](), [CSS](), [HTML](), [JavaScript]() Tags: [accessibility](), [algorithm](), [browser](), [build](), [code](), [coding](), [css](), [html](), [javascript](), [navigation](), [syntax-highlighting]() ### AI overview Coding Challenge #125 asks readers to build an online diff viewer in the browser.

The site supports interactive JavaScript code blocks, syntax highlighting, DOM output, rendering functions, and KaTeX mathematics, motivated partly by the author's AI studies. ### Source excerpt I just pushed a new backend for this site. I love having a quick direct connection to my site: being able to write content and publish it with a quick press of a key. Previously, I was using logseq for this but while writing my latest post I got frustrated with how slow it is. I use this site not just for writing content, but also quick sketches of interactive code. I can easily make a code block interactive by tagging it to run inline in the page, making it easy to develop quick ideas. For this to work, publishing needs to be instant and the editing experience is vital. In logseq, it took 3-4 seconds to publish content (some of this is due to how I wired up the process) but worse is the editing experience in large posts with lots of code was very slow and frustrating. My new setup uses obsidian to write content which I've found extremely polished and fast. A big difference is logseq is an "outliner" and obsidian treats content as a simple file of text. I'll miss certain features of outliners but overall the UX improvement is very much worth it. New site allows code with syntax highlighting (just as before): function calc(x) { return x + 6 * 10000; } ^659b71 I can make code blocks easily run by adding the run tag to a codeblock. It looks like this: ```js run function calc(x) { return x + 5 * 10; } return calc(10); ``` ^4536cf If I want to show something from the code I can just return the value and it appears in the DOM: (note: skipping interactive content block) ^ef4d56 Alternatively I could use a render function within the code block to do the same thing: render(calc(10)). It's a little more verbose, but the benefit with this is I can render multiple things and at different places in the call stack. I also took the time to support math which is rendered with katex. For example $g(\\sqrt{a^2 + b^2})$ renders as this: $g(\sqrt{a^2 + b^2})$. This new workflow will be instrumental in my AI studies, which was the primary motivation for this rehaul.
