Elanat’s WFC tutorial describes a server-driven interface in which Phoenix generates commands and WebFormsJS applies them to the browser’s existing HTML DOM. The server sends instructions rather than maintaining a continuously synchronized copy of the page. The article presents this as a stateless, REST-oriented approach, but does not provide independent tests or measurements confirming its scaling or performance claims.
How WFC’s server-driven UI model works
The flow described in the tutorial is Phoenix controller → WFC command generation → response carrying commands → WebFormsJS in the browser → updates to the existing HTML DOM. The browser retains the actual DOM; server code creates instructions for the browser runtime to execute. HTML remains the interface rather than being replaced by a proprietary UI markup language.

In the article’s formulation, “The server orchestrates. The browser executes. HTML remains the interface.” That is an architectural description, not evidence of a particular performance or compatibility result. Read Elanat’s WFC tutorial.
What the Phoenix example does
The tutorial first renders a conventional HTML form from a Phoenix view. In a controller, it uses WebFormsCore.WebForms and InputPlace to create commands targeting that form. The examples include changing the form’s font size and background color, disabling its submit button, adding an h3 element, and setting the heading’s text. The controller then returns WebForms.response(form) as the response body.
#1 Best Overall
This demonstrates the article’s central split: Phoenix generates the commands in response to a form POST, while WebFormsJS executes them against the page in the browser. The sample dependency is {:wfc, "~> 2.1"}, followed by mix deps.get. Those are the versions and commands shown in the tutorial, not a confirmation that this release remains current or compatible with a given Phoenix application. Check the package and framework compatibility information before adopting them.
What “stateless” means in the article
Elanat describes command generation as request-scoped: each request can produce commands without requiring the server to keep a continuously synchronized DOM representation. The tutorial argues that independent requests can therefore be distributed across server instances. This is a design claim; the article does not report a scaling test or establish how a particular application’s other state, such as sessions or database records, should be handled.
Transport choices described by WFC
The article names three possible ways to carry commands. Its comparisons are qualitative, not benchmark results.

|---|---|---|
| HTTP | Ordinary form submission | Request and response |
| Server-Sent Events (SSE) | Continuous server-to-browser events | One-way server to browser |
| WebSocket | Real-time communication | Bidirectional |
The tutorial supplies no comparative figures for latency, reliability, cost, or scaling, so the transport examples should not be read as rankings on those measures. The appropriate choice depends on the interaction pattern an application needs.
Rank #3
What the article establishes—and what it does not
The tutorial presents a concrete Phoenix example and an architectural model for sending server-generated commands to a browser runtime that updates HTML. Its claims about statelessness, horizontal distribution, and transport flexibility remain claims made by the article rather than independently measured outcomes. It also does not establish current package status, framework compatibility, security properties, or the absence of client-side build tooling.
A DEV Community copy of the same article is available, but it is not independent evaluation. Treat the tutorial as an introduction to WFC’s proposed architecture, and verify current project documentation and compatibility before using it in production.
