Utilizing Deno's Standard Library for Parsing and Caching
Dynamic Content Rendering with Markdown and Styling
Implementing Client-Side Interactivity with Islands
Deploying Deno Applications and Managing Locales
In the realm of full-stack development, leveraging modern tools and technologies can significantly enhance productivity and code quality. Understanding how to efficiently manage data loading and error handling is crucial. When loading data, such as blog posts, it's important to handle potential errors gracefully. Introducing mechanisms to return null when a post doesn't exist can prevent application crashes and improve user experience.
Deno, a modern JavaScript runtime, provides a standard library that simplifies many common tasks. For instance, parsing front matter from content files is straightforward with Deno's standard library. This library includes various utility functions that are maintained to the same standards as Deno itself, ensuring reliability and security. By caching remote modules, developers can reduce redundant operations and improve application performance.
Rendering dynamic content often involves working with markdown. Converting markdown to HTML can be achieved using libraries like Deno's GitHub flavored markdown (GFM). Rendering markdown content with proper HTML elements allows for a more polished presentation. Applying styles to markdown elements, such as tables and headers, can enhance the overall aesthetic of a web page, making it more user-friendly.
Client-side interactivity is a key component of modern web applications. Fresh, a full-stack web framework built for Deno, introduces the concept of islands to manage client-side interactivity. Islands are sections of a web page that require interactive features. By isolating interactivity to specific components, Fresh minimizes the amount of JavaScript required on the client-side, enhancing performance while maintaining user experience.
Deploying applications efficiently is another crucial aspect of development. Deno Deploy offers a seamless way to deploy Deno applications, allowing developers to run code globally with minimal latency. Understanding how to manage locales and user preferences is essential, especially for applications with a global user base. Using middleware to parse accept language headers and cookies ensures that content is displayed according to user preferences, enhancing accessibility and user satisfaction.
The process of building a full-stack application involves several interconnected components that must work harmoniously. By mastering tools like Deno and Fresh, developers can create scalable and efficient applications with ease. These insights into error handling, data loading, dynamic rendering, client interactivity, and deployment strategies provide a solid foundation for any developer looking to enhance their skill set in modern web development.

FAQ
Deno is a modern JavaScript runtime similar to Node.js, but it supports TypeScript out of the box. It is designed to provide a secure environment for executing JavaScript and TypeScript code, with built-in utilities like a formatter, linter, and testing framework. Deno emphasizes security and supports Web APIs for operations like fetching resources, mirroring the functionality available in modern browsers.
Deno and Node.js are both JavaScript runtimes, but Deno provides several enhancements and differences. Notably, Deno includes built-in support for TypeScript, offers a more secure sandbox environment by default, and does not use the npm package manager. Instead, Deno imports modules using URLs, similar to importing scripts in a web browser. Deno also includes built-in tools like a formatter and linter, which are not built into Node.js.
Deno Deploy is a distributed system designed to run JavaScript, TypeScript, and WebAssembly at the edge, close to users. It aims to minimize latency by running code in global data centers closer to the end user. Deno Deploy integrates directly with the Deno runtime, providing a seamless experience for developers to run their applications across the globe efficiently.
To create a new Deno project, start by creating a new directory and a main TypeScript file. Deno does not require a package.json file or node_modules directory. You can run your script using 'deno run' followed by your script name. For structured projects, Deno offers utilities like a project initializer which helps in setting up projects with recommended configurations.
Fresh is a full stack web framework specifically designed for Deno. It leverages the capabilities of Deno and is optimized for building fast, efficient, and scalable web applications. Fresh follows the islands architecture, allowing parts of your application to be interactive, minimizing the amount of JavaScript shipped to the client, and improving load times and performance.
Yes, Deno has a built-in testing framework that allows you to write and run tests for your applications. You can create test files with '_test.ts' suffix and use 'deno test' to execute them. Deno's testing framework supports features like test isolation and real-time feedback, making it a powerful tool for developing robust applications.
Today's workshop is about building a full stack application using Deno and Deno deploy. We will create a blog with personalized blog entry pages and explore Deno's features such as TypeScript support and integrated tool chain. Deno deploy allows for easy deployment of Deno applications, and Fresh is a full stack web framework optimized for fast and scalable applications. The workshop covers topics such as setting up Deno, creating projects with Fresh, handling static pages and blog posts, testing, client interactivity, and deployment using Deno Deploy and GitHub Actions.

Deno 1.9 introduced a new web server API that takes advantage of Hyper, a fast and correct HTTP implementation for Rust. Using this API instead of the std/http implementation increases performance and provides support for HTTP2. In this workshop, learn how to create a web server utilizing Hyper under the hood and boost the performance for your web apps.
In this workshop we will build and deploy a full stack GraphQL application using Next.js, Neo4j, and Vercel. Using a knowledge graph of news articles we will first build a GraphQL API using Next.js API routes and the Neo4j GraphQL Library. Next, we focus on the front-end, exploring how to use GraphQL for data fetching with a Next.js application. Lastly, we explore how to add personalization and content recommendation in our GraphQL API to serve relevant articles to our users, then deploy our application to the cloud using Vercel and Neo4j Aura.

Deno aims to provide Node.js compatibility to make migration smoother and easier. While Deno can run apps and libraries offered for Node.js, not all are supported yet. There are trade-offs to consider, such as incompatible APIs and a less ideal developer experience. Deno is working on improving compatibility and the transition process. Efforts include porting Node.js modules, exploring a superset approach, and transparent package installation from npm.
JavaScript Should Come With Batteries: Deno is a next-generation JavaScript runtime that addresses the lack of built-in tooling in JavaScript. It provides a secure and simple way to develop applications with built-in testing, linting, formatting, and a language server for VS Code. Deno is compatible with Node.js and NPM, supports web standard APIs, and allows code portability between frontend and server. It also offers features like a built-in database, a key-value store, and transparent monetization with Deno Deploy.
The Talk discusses forced optimization with Node and Deno, with Deno aiming to pursue the same goals in a more expansive and modern way. Deno has built-in support for NPM and enforces security constraints. It also has a key-value database called Deno KV, which will be a core part of the Deno 2 API. Deno Deploy is a serverless Edge Functions platform powered by FoundationDB, optimized for fast reading and ideal for building eCommerce sites or application servers at the edge. Deno 2.0 is coming soon with more features under development.
This Talk introduces the Remix architecture patterns for web applications, with over 50% of participants using Remix professionally. The migration from single page applications to Remix involves step-by-step refactoring and offers flexibility in deployment options.
