It's that time to share some info on what's happening in the world of UIBUILDER. 
v7.5 will have a number of improvements, so far:
-
Updates to the front-end router library
- A new menu-generator along with new router config options. You will be able to auto-generate navigation route menu's, both horizontal and vertical, anywhere on-page. The menu's will be responsive and accessible.
- Along with the generator, there will be improvements to the layout and styling of the menus.
-
Two new Editor actions are being added to make it super-easy to open a uibuilder web page or open the IDE code editor for the uibuilder instance.
-
In addition to the menu improvements, the default style sheet will have:
- Updated table headers - making table headers sticky automatically - great for long data tables.
- The accent-color has been updated to use the default secondary color instead of the brand color.
summary elements now get the cursor set to pointer.
On the development side, there are the usual tidy-ups of code. A continual gradual renaming of libraries/modules to match whether they are CommonJS/Script or ES Module's. New ESBUILD configurations also being used which improves robustness of the build processes.
Also under way for the uibuilder front-end client library are some experimental features. Specifically a new "reactive" feature that, when complete, will bring some of the reactive data features you are used to with front-end frameworks like VueJS but, of course, not needing a framework as they leverage vanilla HTML/JavaScript. Not quite sure whether that will be ready for v7.5.
Reactive variables mean that you can update a variable in JavaScript (or remotely from Node-RED) and the UI will update automatically.

I've also done some additional work on the styles. Namely to improve the default text contrast slightly and improve form elements:
(Note that for both images, the cursor was hovering over the "Home Summary" menu item).
And yes, I really am working on some theme editor forms.

Some more exciting things beginning to work their way towards the next release now.
Firstly, if you are using uibuilder's custom Express web server (rather than the one defined by Node-RED), you can now specify a .public folder which is mounted as the root URL. So ~/.node-red/uibuilder/.public/index.html would be served up as the / url path. Not needed, of course, if using Node-RED's built-in server since you can specify a public folder in settings.js.
Next, for anyone creating single-page apps using the uibRouter library, a simple auto-menu feature is added. Currently only generates a horizontal, single-level navigation menu but will eventually be expanded for multi-level and vertical menus. No coding required for this. Just an HTML element to act as the parent and an updated route configuration.
Next big thing is an experimental version of the client library. This lets me play with more esoteric and exciting features for he front-end without messing up the actual client. Some interesting experiments under way at the moment. These may or may not make it to v7.5:
-
A new template feature which lets you do something like this in your HTML file:
<template id="greeting-template">
<h3>{{title}}</h3>
<p>Hello {{user.name}}, you have {{user.notifications}} notifications.</p>
<p>Today is {{date}}.</p>
</template>
<div uib-template="#greeting-template" id="template-output">
<!-- Template will be rendered here -->
</div>
-
Some extended attributes not dissimilar to VueJS
usb-bind: <p>Hello, <span uib-bind="userName">World</span>!</p> - binds content to a JavaScript variable.usb-show: <div uib-show="showGreeting" style="display: none;">HELLO</div> - binds to a boolean variable for showing/hiding content.
-
Some nicer popover dialogue boxes - for use with newer browsers.

Now I'm feeling more confident with UIbuilder, creating a SPA layout instead of individual instances is next on my list!
Hope it makes v7.5.0 as I need all the help I can get 
Yes, the basic one will certainly be in v7.5 - the bells and whistles (multi-level menus, vertical menu's and tabbed interfaces) will probably not. So just a single layer.
Here is an example of the output:
<header>
<h1 class="with-subtitle">Home Panel: <uib-var variable="uibrouter_CurrentTitle" id="uib-var-1">Theme Editor</uib-var></h1>
<div role="doc-subtitle">Using the UIBUILDER IIFE & router libraries</div>
<div id="menu1" style="position: relative;">
<nav aria-label="Main Menu" class="horizontal" aria-expanded="false">
<button class="menu-toggle" aria-expanded="false">
<svg viewBox="0 0 0.8 0.8" xmlns="http://www.w3.org/2000/svg">
<path d="M0.1 0.15h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 1 1 0 -0.1m0 0.2h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 1 1 0 -0.1m0 0.2h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 0 1 0 -0.1"></path>
</svg>
</button>
<ul class="routemenu" role="menubar">
<li role="none"><a role="menuitem" href="#theme" data-route="theme" class="currentRoute" aria-current="page">Theme Editor</a></li>
<li role="none"><a role="menuitem" href="#route01" data-route="route01">Home Summary</a></li>
<li role="none"><a role="menuitem" href="#wanted" data-route="wanted">To Do</a></li>
</ul>
</nav>
</div>
</header>
It is everything inside the div - the div itself is the placeholder. So you can easily manually create a menu for now.
This is the JavaScript that configures the routes in the example above:
const routerConfig = {
defaultRoute: 'route01',
hide: true,
routes: [
{ id: 'theme', src: './fe-routes/theme-editor.html', type: 'url',
title: 'Theme Editor', description: 'Theme editor.' },
{ id: 'route01', src: './fe-routes/route01.html', type: 'url',
title: 'Home Summary', description: 'A summary view of the home.' },
{ id: 'wanted', src: './fe-routes/wanted.html', type: 'url',
title: 'To Do', description: 'My to do list for this site.' },
],
routeMenus: [
{
id: 'menu1',
menuType: 'horizontal',
label: 'Main Menu',
},
],
}
const router = new UibRouter(routerConfig)
What is the purpose of the button in the menu?
<button class="menu-toggle" aria-expanded="false">
<svg viewBox="0 0 0.8 0.8" xmlns="http://www.w3.org/2000/svg">
<path d="M0.1 0.15h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 1 1 0 -0.1m0 0.2h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 1 1 0 -0.1m0 0.2h0.6a0.05 0.05 0 0 1 0 0.1H0.1a0.05 0.05 0 0 1 0 -0.1"></path>
</svg>
</button>
As it says - it is a menu toggle button.
Hint: try reducing the width of your display. 
Further updates:
On further reflection, some of the features I was thinking about that mirror front-end frameworks like VueJS do not actually appear to be that useful for UIBUILDER. Specifically the uib-bind and uib-show extended attributes. This is because the uib-topic attribute already means that we can update elements dynamically simply by sending a message with the right topic. This can be done not only from Node-RED but also from front-end code with uibuilder.set('msg', {...}). Showing and hiding can be done with a simple CSS Class change. We don't need to have a uib-on (replicating things like Vue's @ binding) either since we can either use the normal attributes to reference a function or we can use JavaScript event handling. This all fits in better with UIBUILDER's principal of following HTML standards and not inventing a new framework. KISS
So instead of adding complexity, we simply need to make use of what is already there. I will document this better.
What is now in progress is a long-awaited improvement to the main uibuilder node. To enable easier running of build scripts on your front-end code. So if you want to optimise or you really do want/need to use a framework - Svelte for example - you won't have to have a remote terminal session running just to run the build process. A new tab called "Scripts" will be available:
The scripts are defined in the instance's package.json file as normal when using npm. However, install and update are also included as these are built-in npm scripts.
Obviously you can do a lot more than simply run a build script. npm lets you run pretty much anything you put into the command. Output from the command will be available to view directly.
You can change the list of scripts simply by editing the package.json file:
So this feature will let you do anything you like to your uibuilder instance folders and files.
