configuration

You've installed Superglue and now you're ready to configure your app.

application_visit.js

!!! tip If you want a progress bar, this is the first thing you'll want to configure after installation.

This file contains the factory that builds the remote and visit function that will be passed to your page components and used by the data-sg-visit and data-sg-remote UJS attributes.

This file is meant for you to customize. For example, you'll likely want to add a progress bar, control how visits work, or flash when the internet is down.

page_to_page_mapping.js

!!! info Stop by the tutorial to learn how to work with this file.

**Vite Users** This step can be entirely optional if you're using Vite. See
the [recipe](recipe/vite.md) for more information.

This file exports a mapping between a componentIdentifier to an imported page component. This gets used in your application.js so that superglue knows which component to render with which identifier.

For example:

const pageIdentifierToPageComponent = {
  'posts/edit': PostsEdit,
  'posts/new': PostsNew,
  'posts/show': PostsShow,
  'posts/index': PostsIndex,
}

application.js

This is the entry point of your application and uses Superglue's [Application] component. There's nothing to do here, but if you need finer control of how redux is setup, you can build your own Application using the source as inspiration.

flash.js

The installation generator will add a flash.js slice to app/javascript/slices and will work with the Rails flash. You can modify this however you like, out of the box:

• When using data-sg-visit, all data in the flash slice will be cleared before the request.

• When using data-sg-visit or data-sg-remote, the recieved flash will be merged with the current flash. You can change this behavior by modifying the flash slice.

!!! hint If you're curious how this works, in your layout, application.json.props, the flash is serialized using flash.to_h

To use in your page components, simply use a selector.

import { useSelector } from 'react-redux'

...

const flash = useSelector((state) => state.flash)

then use the flash as you would normally in a controller

def create
  flash[:success] = "Post was saved!"
end
