Double Click: Web 3 is Coming! But is it Over Hyped?

Oct 5, 2021

2 min read

Welcome to the Double Click! This is the weekly blog series that shines a spotlight on emerging technologies, technological concepts, and community projects that enrich the JavaScript Ecosystem!

This week, we're talking about all of the hype and controversy surrounding Web 3, or the future of the web. If you are just hearing about Web 3 for the first time, it is the concept that the "web" as we know it, will eventually be composed largely of decentralized applications and tokenized systems that allow users to engage in peer-to-peer interactions without the use of enterprise sites and services.

I know this might seem vague, but it might make more sense if we consider that "Web 1" was the period of time when the internet consisted of usenets and message boards, and "Web 2" occured as enterprises began digital products to create an interfaceable internet.

"Web 3" now refers to a potential future where most of our web interactions will be facilitated by machines and decentralized protocols rather than centralized services, such as those owned by banks and payment processors.

I am extremely excited about the potential that blockchain technologies have to revolutionize the web as we know it. If you follow any of my recent blog posts, you will know that I am a huge proponent of decentralized applications, and even offer Solidity development services through This Dot Labs.

That being said, developers who are just getting into the industry do not need to worry that all of their hard work learning JavaScript and frameworks was for naught.

Though blockchain will only continue to grow in popularity and expand in functioning, we're not quite on the doorstep of a web revolution that will fundamentally change the sort of skills and expertise needed on the market. We will still need centralized applications, web sites, mobile applications, and more for quite a while.

However, if you are interested in becoming an early blockchain adopter, there are tons of opportunities to become involved. With all of the Web 3 hype, there are hundeds of new projects and companies popping up with opportunities for developers.

But if you aren't quite ready to make the full leap into this pioneering space, you can contribute to blockchain community projects, such as those offered by various networks and tokens, or building your own decentralized application. After all, JavaScript and Solidity use nearly identical syntax!

But what do you think? Do you believe we're on the precipice of a great new web development revolution, or are you not quite buying the hype yet? Be sure to let me know by tweeting me at @ladyleet.

JSR - The cross-platform package manager for ESM

JSR - The cross-platform package manager for ESM Move over NPM, there’s a new package manager in town. JSR is a new open-source package registry for JavaScript and TypeScript. This particular release has caught my attention, and I’m excited to explore if and where JSR fits into our overflowing ecosystem. Setting the stage The JSR website has a page called Why JSR? I want to explore the _why_ a little bit further. I think that the _why_ points to JSR potentially being the future of the JavaScript ecosystem. NPM and JavaScript modules If you’ve found yourself confused about publishing and consuming packages and modules in the modern ESM era, you’re not alone. When NodeJS was created, there was no standard for JS modules. Node introduced CommonJS modules, and NPM provided a way to publish and consume these modules in our applications. It’s been years now since ES Modules became a standard and we are still in a weird module purgatory with no clear end in sight. JSR represents a fresh start, free from the baggage of the Node and NPM ecosystems. JavaScript runtimes and interoperability New JavaScript runtimes are popping up every year. WinterCG (_Web-interoperable Runtimes Community Group)_ was started to improve interoperability for the various runtimes with some standard APIs. Node has made steps towards this goal, but it might never get all the way there and NPM is coupled pretty tightly to that ecosystem. JSR supports several runtimes (depending on the package). This is a huge opportunity for it to become the package manager for the ecosystem at large. See cross-runtime support section for more details. NPM Compatibility JSR doesn’t end up being a complete departure from NPM since it includes an NPM compatibility layer. The docs highlight some limitations and provide deeper technical details on how this piece works. The simple overview is that you can install and use packages from JSR to a Node/NPM based project. The packages will get added to your package.json and node_modules directory. About the same as any package installed from NPM. JSR Overview At a high level, JSR is very similar to NPM. You can search for packages on the website. You can publish packages to their registry, and you can download packages from it as well. We touched on the two major features that set it apart from NPM: It only supports ESModules, and it has cross-runtime support. In the rest of the article we’ll explore the essentials (package management) and also some other really great features that feel like are bringing the JS package management ecosystem up to speed with our modern workflows. Native TypeScript I have to say I’m not surprised by this feature, considering JSR was developed by the same people behind Deno (a runtime that supports TS natively). It’s a great feature. If you haven’t figured it out yet TypeScript is a big deal and doesn’t seem to be fading away anytime soon. So what exactly does TS support look like in a package manager, though? If your runtime supports TypeScript natively (like Deno) - it can consume the TS files in your package directly. For environments that don’t, it will automatically compile your code to JavaScript and package it with type declaration files (.d.ts). Pretty, stinking, cool. The docs include a page called “about slow types”. It is probably worth a read on its own ,but the TLDR is that JSR will analyze your TS code and penalize you in certain ways if you have some type code that it considers to be slow. On the page, it outlines exactly what these penalties are, as well as what it considers slow types to be. Slow types will also come into play when we get into package scoring later in the article. Packages The docs have a page dedicated to packages. It covers some important stuff like deleting packages, versioning, documentation, and publishing. We’ll touch on some of it with an emphasis on the things that are done differently or better than with NPM. jsr.json file jsr.json is a configuration file that specifies a name, version, and exports of a package. It doesn’t include a list of dependencies like you would have in a package.json file. This is a configuration file for a package to be published to JSR. JSR dependencies are defined in an import map file or a package.json file, depending on the runtime. Adding packages to a project Adding packages to your project will vary depending on your target runtime. Here’s an example of installing it for Deno and NPM using various package managers. For Deno, an import map entry is created. For NPM, it gets installed as an NPM package using the JSR NPM compatibility layer. ` If the runtime has native JSR support, you don’t need to explicitly install packages. You can important them using the jsr: scheme. ` As you can see semantic versioning is supported and works similarly to NPM. Publishing packages If you want to publish a package to JSR, there are many important rules you need to be aware of. I recommend reading “Publishing packages” before moving forward with this. The main things to note are: ESModules only, npm packages are supported, JSR packages are supported, and node APIs are supported. So there aren’t many constraints. You just need to understand how exactly to do these things. IE: how do I use NPM dependencies, how do the imports work, etc? Once you’ve got all that down, you will be ready to publish your first package to JSR 😃 Documentation JSR emphasizes quality package documentation. It’s one of the factors in their package scoring algorithm, which we will discuss shortly. The important parts of a package’s documentation include: * a README.md file * symbol documentation - functions, interfaces, classes, etc * module documentation - docs for each exported module in a package The symbol and module documentation are written using JSDoc. The JSR website generates some nice documentation based on these 3 pieces on your package page. This means you can understand a package's entire public API without ever leaving jsr.io. Browser support The cross-runtime support is amazing, but I was curious where the original JavaScript runtime fit (the browser). According to the documentation: “You can use JSR with any tool that supports ES modules, and either has native support for JSR or supports npm packages using node_modules.” Since modern web browsers support ES modules, I will count this as JSR support. From what I can tell, though, there is one caveat. To include a module on a web page, we need a URL to download it from. Can we publish our package to JSR and use it to load a module via a script tag? According to the JSR usage policy, no. The “Unacceptable use” section states: “It is not acceptable to use JSR as a CDN for serving assets directly to web applications in a browser, except for development purposes.” So, it seems that this is a no-go for now. We will probably need to wait a bit for CDN services like jsdelivr to pull packages from the JSR registry, similar to what they do with NPM currently. Other notable features We’ve covered the most important bits about package management, TS support, NPM compatibility, etc. But there are still a few unique features that add an extra bit of sparkle to JSR. Scoring We mentioned earlier that documentation plays a part in a scoring algorithm. JSR analyzes all of the packages published to its registry and assigns them a score based on certain criteria: documentation, best practices, discoverability, and compatibility. This score is shown with every package listed on the website. You can also add a shiny badge to your README if you’re particularly proud of something. It’s still early on, so it’s likely this will evolve as time goes on. It’s an interesting gimmick, at the very least! Summary I am excited to have a new cross-platform compatible package manager that only supports ESM. As useful as NPM has been all these years, it carries a lot of baggage from “the olden days”. JSR’s native TypeScript support and reliance on modern standards is a breath of fresh air. It feels like I can publish a simple package without much ceremony. I’m excited to release my first package to JSR soon :)...

This is the Worst Thing a DevRel Team Could Do

At its core, a successful Developer Relations (DevRel) program focuses on forming strong connections within its target audience to ensure that developers can easily connect with the company or organization behind the product they’re using. Great teams in DevRel build genuine relationships, earn trust, and actively engage with developers. DevRel takes a different approach from traditional marketing strategies. Instead of just chasing numbers and leads for sales, it puts emphasis on making developers happy and retention. This creates a cycle of feedback between users and a company, helping to better understand their needs and fostering a sense of community among users. There have been organizations that consider DevRel a revenue-driving function, but this is where challenges arise, since DevRel teams cannot consistently show value in this area and meet the expectations of stakeholders expecting this based on where their focus and the profession lies. When DevRel professionals are forced to be revenue drivers, the breakdown between developers and that company is inevitable. Developers can smell hidden agendas from a mile away. They realize when their needs are being overlooked in favor of sales initiatives. *“Companies fail at DevRel when they try to turn them into sales teams. This hurts customer trust.” - Michael Liendo, Senior Developer Advocate at AWS. * Developers care about education, resources, opportunities, and the overall experience of a product or platform. When they are a target for sales pitches, they leave or shut down. Their focus is getting the job done, and they talk to companies to solve problems in their development lifecycle, not to be on the receiving end of a pitch. Furthermore, since all successful DevRel teams are focused on building authentic relationships with developers, strategic partnerships with other organizations will be hard to come by or have dismal retention numbers since no one wants to be associated with trying to sell to developers. Good DevRel teams are focused on helping developers and understand that being helpful goes a long way to help the sales cycle. Many DevRel efforts also focus on providing value to a community before asking for something in return. The trust and authenticity of brand building in this area and those initiatives - the loyalty a DevRel team is trying to generate - many times does not make direct corollary sense from a monetary perspective, and sales organizations often overlook the non-monetary value and impact these efforts generate and how they correlate to long-term growth for an organization. In DevRel, genuine connections matter more than immediate revenue. When teams prioritize developers' needs over sales, trust grows, fostering lasting relationships that drive long-term success. Treating DevRel as solely a sales function erodes trust and misses the true value of building authentic partnerships and community loyalty. Interested in learning more about launching your own DevRel program, feel free to reach out!...
