V8: Server side prerendering

Hello there,

Going straight to the point:

• New version with server-side prerendering in order to have app SEO friendly
• Documentation has been updated

See the migration guide for the detailed list of changes

Event Handler scope

A scope can be added to event handler in order to trigger event handler updates.

In a scenario where we want to remove a element from a list, a solution is to create an EventHandler which got the element id set outside.
The event handler returned will always have the same addr, which prevent the package to define that an update should be done on the given element.

To solve this, a scope has been added to the methods that set EventHandler.
Here is the an example:

type issue499Data struct {
	ID    int
	Value string
}

type issue499 struct {
	app.Compo

	data []issue499Data
}

func newIssue499Data() *issue499 {
	return &issue499{}
}

func (c *issue499) OnMount(app.Context) {
	c.data = []issue499Data{
		{11, "one"},
		{22, "two"},
		{33, "three"},
		{44, "four"},
		{55, "five"},
		{66, "six"},
		{77, "sever"},
		{88, "eight"},
		{99, "nine"},
	}
	c.Update()
}

func (c *issue499) Render() app.UI {
	return app.Div().Body(
		app.H1().Text("Issue 499"),
		app.Div().
			Body(
				app.Range(c.data).Slice(func(i int) app.UI {
					d := c.data[i]
					return app.Button().
						ID(fmt.Sprintf("elem-%v", d.ID)).
						OnClick(c.newListener(d.ID), d.ID). // HERE the element ID is added in order to trigger the handler update since the func pointer returned by newListener is always the same.
						Text(d.Value)
				}),
			),
	)
}

func (c *issue499) newListener(id int) app.EventHandler {
	return func(app.Context, app.Event) {
		for i, d := range c.data {
			if id == d.ID {
				c.data = append(c.data[:i], c.data[i+1:]...)
				c.Update()
				return
			}
		}
	}
}

App resize listener

Hello there,

This release brings a way to be notified that that app window size changed within components. It can be done by implementing the Resizer interface:

type myCompo struct{
    app.Compo
}

func (c *myCompo) OnAppResize(ctx app.Context) {
    // Handle app resizing.
}

It can be quite a handful when building layout components. Shell and Flow has been refactored and now uses this mechanism.

Context app update fix

• Context in OnMount now correctly reports whether an app update is available.

Blank navigation fix

Hello,
Small patch today:

• Fixed a bug that prevented _bank navigation for paths within the app host
• Context now have a variable that reports whether the app has been updated in the background

Detect app update

Hello there,

This version introduces the Updater interface.
It allows a component to be notified that the app has been updated.

This will allow notifying your users that the app has been updated and modifications are available by reloading the page.

Check the Lifecycle article in the doc to see how to use it.
