Our review

Go framework for building server-rendered user interfaces, with components, forms, and real-time updates via WebSocket.

Strengths

Fully server-side architecture simplifies business logic and state management
Modular, reusable Go components
Advanced form handling and server actions
Real-time updates via WebSocket without complex JavaScript

Limitations

Requires solid Go knowledge
Partial documentation (separate MD files)
Likely small community

When to use it

For building Go web applications that need dynamic UI with server interactions and real-time updates.

When not to use it

For highly interactive client-side applications or when React/Vue are already familiar.

Examples

Create a basic page with g-sui

Using g-sui, create a Go web application with a home page that displays a greeting message and a button that increments a counter. The counter state should be managed on the server and updated via a server action.

Set up a form with server action

In g-sui, implement a contact form with fields for name, email, and message. On submission, use a server action to validate and display a success alert. Use the Form component from g-sui.

Create a data table with sorting

Using g-sui's data management features, create a page that displays a table of users with columns for name, email, and role. Enable sorting by name and filtering by role. Use the data collation utilities from the framework.

g-sui Framework

Server-rendered UI framework for Go. All HTML generation, business logic, and state management occur on the server. Interactivity achieved through server actions and WebSocket patches.

Quick Start

package main

import "github.com/michalCapo/g-sui/ui"

func main() {
    app := ui.MakeApp("en")

    app.Page("/", func(ctx *ui.Context) string {
        return app.HTML("Home", "bg-gray-100",
            ui.Div("p-8")(
                ui.Div("text-2xl font-bold")("Hello World"),
            ),
        )
    })

    app.Listen(":8080")
}

Core Philosophy

Server-Centric Rendering - All HTML generated server-side as strings
String-Based Components - Components are Go functions returning HTML strings
Action-Based Interactivity - User interactions trigger server handlers returning HTML
WebSocket-Enhanced - Real-time updates via /__ws endpoint

Key Types

type Callable = func(*ui.Context) string  // All handlers return HTML
type Attr struct { ID, Class, Value, OnClick, OnSubmit, ... }  // HTML attributes

Common Imports

import "github.com/michalCapo/g-sui/ui"

Development Commands

go run examples/main.go      # Run example app
go test ./...                # Run all tests
go test ./ui/...             # Test UI package
go build                     # Build project
./deploy                     # Create and push new version tag

Releases

To create a new version release:

./deploy

The deploy script automatically:

Starts at version v0.100 if no tags exist
Increments the minor version by 1 (e.g., v0.100 → v0.101 → v0.102)
Ensures working tree is clean before tagging
Creates an annotated git tag and pushes to remote

Version numbering: v0.XXX format, auto-incremented from v0.100.
