This is a significant development as it opens up new possibilities for code demos and distributed computing. During the discussion, the names of various platforms such as Stackblitz, CodeSandbox, Nodebox, and web containers were compared. While opinions on the coolness of the names varied, there was agreement that the ability to run Node.js in the browser is a game-changer. This shift towards browser-based computing is likely to become more prevalent in the future, with platforms like Stackblitz and Replit leading the way. These platforms enable users to share demos and save them, making learning and collaboration more efficient. The benefits of running Node.js in the browser include eliminating the need for setting up complex environments and allowing for quick and easy sharing of code. Additionally, the discussion touched on the potential future of coding entirely in the browser. Overall, the ability to run Node.js in the browser represents a major advancement in web development and is a trend worth keeping an eye on.
Interactive code playgrounds for easier learning: Code playgrounds in browsers simplify learning by allowing users to write and run code directly, eliminating complex setup processes and external servers, while providing a secure and sandboxed environment.
The future of educational courses, especially those focused on coding, may involve more interactive environments, such as code playgrounds, to make learning easier for beginners. These code playgrounds allow users to write and run code directly in their browser, eliminating the need for complex setup processes and external servers. This not only simplifies the learning experience but also addresses security concerns and costs associated with remote development environments. Additionally, the use of code playgrounds in the browser provides a more secure and sandboxed environment for users to learn and experiment with code.
Developing Node.js apps in the browser using WebAssembly: WebAssembly allows developers to write, build, and run Node.js apps directly in the browser for a faster and more convenient development experience.
Modern web development platforms like Stackblitz and CodeSandbox allow developers to write, build, and run Node.js applications directly in the browser using WebAssembly (Wasm). This is accomplished by creating a pseudo Linux VM environment that can run most Node.js APIs. Developers create files as objects, write their code in package.json and index.js files, and can use tools like NPM install and nodemon for faster development. The applications are run inside iframes, and the output is streamed directly to the user. The platforms are likely mocking or stubbing out some Node.js APIs to make it work in the browser, but the specifics of how they achieve this are not clear. The result is a faster and more convenient development experience, as the code runs in the browser instead of requiring a local Node.js installation. This technology is fascinating and opens up new possibilities for web development.
CodeSandbox and Stackblitz: Running Node.js in the Browser: These platforms enable running Node.js apps directly in the browser using their own CDNs and iframes, but their implementations are not open source.
CodeSandbox and Stackblitz are platforms that enable running Node.js applications directly in the browser through proxying NPM dependencies. They use their own CDNs (Sandpack CDN for CodeSandbox and unknown for Stackblitz) to manage these dependencies. The implementations of these technologies are not open source, despite the libraries being open. They use iframes for handling node modules and messaging between the browser and their servers. The exact workings of what runs on their servers and why messaging needs to go through them remains unclear. These platforms may represent the future of improved developer experience, but their creators are not yet ready to open source them due to investment and development costs.
New Tools for Developers: Web Containers and Notebox: Web Containers and Notebox provide free resources for developers for heavy rendering tasks and note-taking respectively, with Web Containers utilizing Shared Array Buffer and Notebox using APIs, each having unique strengths and limitations.
There are two new tools, Web Containers and Notebox, which offer free usage of their resources for developers, similar to APIs like Stripe. Web Containers utilize a new browser technology called Shared Array Buffer and are best for heavy rendering tasks, while Notebox uses a different set of APIs and works in all browsers. Although Web Containers have limitations like not being entirely offline, they can still be useful for most developers. The speaker shares a personal experience of being frustrated with using Figma due to its online-only nature, but now finds joy in using Figma after overcoming his offline requirements. Meanwhile, the speaker is considering moving on to Penpod due to his personal Adobe policy. Overall, these tools offer significant potential for developers and designers, with each having its unique strengths and limitations.
Discovering limitations in PenPod: While PenPod is a great alternative to Figma, it has limitations when accessing external data due to its browser-based server.
While PenPod is an impressive open-source Figma alternative, it does have limitations. The speaker was initially drawn to PenPod due to its ease of use and its ability to add features that were lacking in his previous design tool, Sketch. However, he discovered that there are limitations to PenPod, particularly when it comes to fetching data from external sources. The browser-based server has course limitations, which can make it difficult to access certain types of data or run certain APIs. This was a surprising discovery for the speaker, as he had assumed that all the features and capabilities of a server-side application would be available in the browser-based version. Despite these limitations, the speaker was overall impressed with PenPod and plans to continue using it for simpler projects. He also expressed disappointment with his previous experience with Sketch, feeling let down by the lack of support and promotion for his course.
Innovations in running VMs and containers in the browser: Companies like Stackblitz and CodeSandbox are leading the way in running VMs and containers in the browser, potentially offering lighter-weight alternatives for simple tasks and enabling Node.js in the browser for interactive full-stack learning.
There's ongoing innovation in the realm of running Virtual Machines (VMs) and containers like Docker in the browser, with companies like Stackblitz and CodeSandbox leading the charge. Although there are limitations, such as these solutions not being open source, the speakers believe these limitations will likely disappear as competition increases. This development is exciting as it could lead to lighter-weight alternatives to running entire Linux containers for simple tasks. Additionally, there's the potential for running Node.js in the browser, which could be a game changer for learning full-stack frameworks through interactive tutorials. Another related topic is Docker Wasm, which may not be as groundbreaking as initially thought, as it seems to be more about using WASM in Docker containers rather than the other way around. Overall, these advancements might not be critical but are still significant and could make learning complex technologies more accessible. So, stay tuned for further developments in this area!
