Hello world input not working

[delaneyj]

v0.2.0 branch

Per the quickstart

package main

import (
	"context"
	"fmt"
	"log"
	"net/http"

	l "github.com/SamHennessy/hlive"
)

const port = 3000

// Step 1
// func home() *l.Page {
// 	page := l.NewPage()
// 	page.DOM().Body().Add("Hello, world.")

// 	return page
// }

// Step 2
func home() *l.Page {
	var message string

	input := l.NewComponent("input")
	input.Add(l.Attrs{"type": "text"})
	input.Add(l.On("keyup", func(ctx context.Context, e l.Event) {
		message = e.Value
	}))

	page := l.NewPage()
	page.DOM().Body().Add(l.NewTag("div", input))
	page.DOM().Body().Add(l.T("hr"))
	page.DOM().Body().Add("Hello, ", &message)

	return page
}

// Step 2.1
// func home() *l.Page {
// 	var message string
//
// 	input := l.C("input",
// 		l.Attrs{"type": "text"},
// 		l.On("keyup", func(_ context.Context, e l.Event) {
// 			message = e.Value
// 		}),
// 	)
//
// 	page := l.NewPage()
// 	page.DOM().Body().Add(
// 		l.T("div", input),
// 		l.T("hr"),
// 		"Hello, ", &message,
// 	)
//
// 	return page
// }

func main() {
	http.Handle("/", l.NewPageServer(home))
	addr := fmt.Sprintf(":%d", port)

	log.Printf("Listing on %s.", addr)

	if err := http.ListenAndServe(addr, nil); err != nil {
		log.Println("Error: http listen and serve:", err)
	}
}

on first keystroke in the input you receive errors

Appears https://github.com/SamHennessy/hlive/blob/2a1de9ceddaa9e3563c1c97e41ea3bdb9e75de8d/hlive.go#L115 is the culprit as *string isn't valid. Going to fork and try to fix.

just so you know I'm deep into not just fixing this but a host of issues, DM'd on slack
