HAVE YOU ALREADY DISCOVERED WEBCONTAINER?

Startup StackBlitz knew what developers were missing and provided it for them by creating WebContainer technology — full-fledged development in the browser. The service is secure and supports JavaScript-related frameworks such as Next.js, Nuxt, Node.js, React, and Angular. The code editor is based on a stripped-down version of Visual Studio Code but will soon run the full and extensible version of Microsoft’s open source editor in the browser. In terms of monetization, the service only allows public projects and syncs with public GitHub repositories for free. Paid tiers starting at $9/month allow private projects.

What can be distinguished from the main advantages:
- From any device, including smartphones, you can open your project from the repository, deploy it, and either continue working or demonstrate your product
- In the browser, you can easily run a web server or database, which usually requires complex settings on your device to fully deploy the entire structure
- VS code is used which gives extensive possibilities to the native editor.

What can be distinguished from the main disadvantages:
- Constant Internet access is required to save all your changes
- Because this is an initial product, there are bugs with the inability to run some libraries or perform an action that requires a real operating system
- There is no protection against the execution of malicious code. Any person who sends a link to their project can embed anything they want there and the platform will automatically execute this when opening the website.

Conclusion
In general, this is similar to Docker with its containers but it does not require a lot of resources to run them in a browser. So the idea is promising and there are no other concerns, except for malicious implementations.
In addition, in the future, the service may greatly simplify the development as a whole because platforms tend to unify and simplify the infrastructure that needs to be deployed. Also, using WebContainer, you can see a bunch of examples of various libraries and projects that work in real time, which makes it easier to understand the documentation of a product.

And what is your attitude to novelties in the market of programming languages?
