Our review

g-sui is a Go framework for server-rendered UI, with reusable components and WebSocket-based interactivity.

Strengths

All HTML rendering happens server-side, simplifying client logic.
Components are Go functions returning HTML strings.
Real-time updates via WebSocket endpoint.
Built-in form handling and server actions.

Limitations

Requires solid Go knowledge and server-side rendering concepts.
No native support for modern front-end frameworks like React or Vue.
Additional documentation spread across multiple files.

When to use it

Use g-sui when building a Go web application that needs minimal JavaScript and centralized server logic.

When not to use it

Avoid g-sui if you require rich client-side interactivity or integration with popular front-end libraries.

Examples

Create a basic g-sui app

Create a g-sui application with a homepage showing 'Hello World' and a second page with a form that submits via server action.

Add a data table

Add a data table to my g-sui project that supports sorting, filtering, and pagination with WebSocket updates.

Implement real-time updates

Implement WebSocket patches in g-sui to push real-time notifications to the UI when new data arrives.

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.
