⚡Via

Pure Go reactive web framework.

Why Via?

Somewhere along the way, the web became tangled in layers of JavaScript, build chains, and frameworks stacked on frameworks. Via takes a radical stance:

• No templates.
• No JavaScript.
• No transpilation.
• No hydration.
• No front-end fatigue.
• Single SSE stream.
• Full reactivity.
• Pure Go.

Example

package main

import (
	"github.com/go-via/via"
	"github.com/go-via/via/h"
)

type CounterState struct{ Count int }

func main() {
	v := via.New()
	v.Page("/", func(c *via.Context) {

		s := CounterState{Count: 0}

		step := c.Signal(1)

		increment := c.Action(func() {
			s.Count += step.Int()
			c.Sync()
		})

		c.View(func() h.H {
			return h.Div(
				h.P(h.Textf("Count: %d", s.Count)),
				h.Label(
					h.Text("Update Step: "),
					h.Input(h.Type("number"), step.Bind()),
				),
				h.Button(h.Text("Increment"), increment.OnClick()),
			)
		})
	})

	v.Start(":3000")
}

🚧 Experimental

Via is still a newborn.

• v0.1 nears.
• Expect chaos.

Contributing

• Via is intentionally minimal — and so is contributing.
• If you love Go, simplicity, and meaningful abstractions — Come along for the ride!
• Fork, branch, build, break things.
• Follow the loop: ⚡Via → Context → Sync → 🧑‍💻 Signals/Actions → ⚡Via → 🗘
• Keep every line purposeful.
• Share feedback: open an issue or start a discussion.

Credits

Via builds upon the work of these amazing projects:

• 🚀 Datastar - The hypermedia powerhouse at the core of Via. It powers browser reactivity through Signals and enables real-time HTML/Signal patches over an always-on SSE event stream.
• 🧩 Gomponents - The awesome project that enables Vias Go-native HTML composition through the via/h package.

Thank you for building something that doesn’t just function — it inspires. 🫶
