I waited for this day too long. Today, I've tried out GitPod, and made it work for a project based on Osm Admin.

Today, I reiterated on what's left in this iteration, and finished the side menu view, and created a trivial home page for the admin area.

After getting the main branch all-green (tests pass, CLI and UI works as expected), I decided that from now on, I'll keep it always green, and use feature branches for all major development.

Then, I started implementing the main menu of the admin area.

Yesterday, I created a template for new projects powered by Osm Admin.

This way, you can create and publish a project in minutes, just follow the README. Yay!

I came with an idea of much cleaner Osm Admin data class "markup", and more straightforward architecture, and I decided to give it a go in a separate experimental branch v0.2, and to see if it's viable.

After three weeks of implementation effort, I can say that it is viable, and it's so much better! And it's not a completely new effort, I mostly copy code from v0.1 and some parts of osmphp/framework:old_v4, and adapt it.

You can already define data classes using new markup, generate the database tables, and query it using new formula syntax. I really wanted to come with some UI working, but there wasn't enough time for that. It stays my priority for the next iteration.

My current goal is to get some minimum Osm Admin user interface and API working - just for one property, one data type, one UI control type, and then improve.

And there is a lot of space for improvement. The main areas are listed in this document.

I'd really appreciate a helping hand, so if you are into this sort of things, DM me on Twitter.

I feel that both attributes decorating data classes, and object model parsed from it are too complex.

Let's have a fresh look at Osm Admin. If I had to start from scratch, how would it be?

Last two weeks were about implementing initial version of an Osm Admin grid, integrating it seamlessly with the editing form, and enabling mass-editing of multiple objects.

After finishing it, I realized that Osm Admin had become bigger than Osm Framework! To keep up, I started writing docs for it.

And now, you have a step-by-step guide for creating a project, adding Osm Admin to it and a practical example of an admin area that you can copy to your project and try it out locally.

Recently, I implemented mass-editing in Osm Admin. It allows you to view and edit multiple objects in a single operation.

This article describes mass-editing of products in a typical e-commerce application.

The last 4 weeks were mostly a vacation. It's been a time for reflection, but still, I delivered some new features.

In Osm Admin, forms already allow creating new objects and saving them to the database, and editing one or several existing objects.

I've also implemented URL query filters that are applied to the underlying database query and that can be displayed in the user interface.

From now on, Osm Framework and all projects built with it - can be installed and developed under Apache and on Windows.

In the user interface, you can narrow displayed data using grid column filters, or filters displayed in the sidebar. To enable that, apply #[Filter\*] attributes to class properties.

Applied filters appear in the URL query parameters, for example, .../edit?id=5+16+19, and on the page.

You can apply filters not only to a grid page, but also to a form page - to mass edit all matching objects, or to an action URL (edit, delete, or custom) - to perform the action on all matching objects.

In the same way, you can apply filters to the API URLs in order to retrieve or modify matching objects in a script.

In Osm Admin, I've finished indexing. It means that whenever you modify an object in the database, the changes are automatically propagated to all dependent indexed properties in the database.

I've also introduced a grid/form pair as the main user interface concept that is optimized for performing operations on multiple objects. There is also a programming interface (API) that will internally work in the same way, but without visuals. I implemented a part of this interface - an object creation form.

Osm Framework and all projects built with it - including this website and Osm Admin - are upgraded to TailwindCSS 3.0.

Today, I finished implementing an object creation form.

It works according to the specs on Interfaces and Forms. Currently, it only supports string and integer input fields; later, there will be a lot more.

Let's review how it works.

In Osm Admin, a form is an integral part of the class user interface. It's a very specific kind of HTML form.

In this article, I'll review what's in a class form, and how it's reflected from the application code.

Yesterday, I described a user interface pattern for managing data of a certain data class using a grid/form pair. Let's call this grid/form pair class interface in the admin area.

In this article, I'll examine what moving parts are inside a class interface.

So far, I've been concerned about how application data is modeled, stored and handled internally.

Yet, the final objective a user interface for viewing and editing it visually.

Let's dream a bit about how it might look like.

Yay, indexing works!

It's changed quite a bit, so let's review how it works from the very beginning.

For the last two weeks, I figured out two core features that will allow Osm Admin to stand out from other CRUD applications:

1. It will allow mass editing of data objects.
2. It will automatically propagate data changes throughout the database.

The foundation for the mass editing feature is data queries. Data propagation will be ensured via indexing.

I've been working on the Osm Admin indexing engine, and it's still in progress. While working on it, I reworked the inner working of data queries. Finally, I've achieved a very clear separation of various Osm Admin concerns, and documented it.

In Osm Core, I added reflection over class methods.

I'm still working on indexing, and it seems to get one more refactoring. But more on that later.

Meanwhile, let's review Osm Admin modules, their responsibilities and dependencies.

After you got a project up and running, let's have a look what's inside. Every directory has its purpose. Learn where to put your creative efforts!

This website got a completely new look. There are new blog posts diving into core Osm Framework features. Osm Framework itself offers more convenient page layout, website-wide header, footer and <head>, customizable error pages. The themes support theme-specific CSS styles and JS scripts not bound to any module. New projects come with a handy bin/install.sh script that simplifies installation on Linux. From now on, run osmh without any parameters.

In Osm Framework, an application is a set of modules that you run as a whole. There are several applications defined in the project, each having its own PHP class. Mostly, deal with the main one, Osm\App\App. Beside the class name, every application also has a name, the main one is named Osm_App.

Access the current application object, and the main parts of Osm Framework, via the global $osm_app object and its properties. Add your own long-living objects there. Run an application using its HTTP or console entry point, or using Apps::run().

Modular software development is a well-known practice of dividing your application into several modules, each doing one thing, and doing it well. It increases readability and simplifies maintenance, as application concerns are fully separated from one another, easier to reason about, and to debug.

Modular development also encourages reuse. It's like a puzzle. Using one set of modules, you'll get an e-commerce application, using another set of modules - you'll get a blog application.

Using dynamic traits, customize anything. Inject your code in the beginning, in the end, or instead of any standard method. Even more, add new properties and methods to the existing standard classes.

Computed properties are one of Osm Framework pillars. They help to execute code only once, and only if it's actually needed. Computed properties control object serialization and caching. They provide meaningful insights into class interdependencies. Finally, computed properties are easy to test.

From now on, this website is deployed on push, and by the way, you can easily play with the website copy locally. In the Osm framework, new Osm_Project application allows reflecting over modules and classes regardless to which application they belong. New experimental project is aimed at quick creation of the Admin UI.

Osm Framework uses Monolog library for logging. Use standard loggers defined in the $osm_app->logs object, or add your own. Control logging in the settings.{app_name}.php and .env.{app_name} files.

After pushing changes to GitHub, osm.software website is updated without any additional manual action. On push, GitHub executes the deployment script on the production server. Most changes are done to content only, and in this case, the deployment script only updates the search index. Otherwise, with the website being on maintenance, it additionally updates Composer and Node dependencies, builds JS and CSS assets, and runs the database migrations.

This article describes our package release process before v1.0.0. In short, every change is released as soon as it's ready, and all dependent packages are updated at the same time.

This article provides a practical example of contributing changes to Osm Framework and other osmphp/* GitHub repositories. It's based on the Osm_Project application pull request.

Today, osm.software reached an important milestone - 100% Lighthouse score.

This article explains how to manage and assign blog categories.

Osm Framework introduced production mode and maintenance mode. osm.software website went live.

Osm Framework introduced JS controllers, and JS unit tests. osmcommerce.com website project was renamed to osm.software, it finalized the post rendering, and introduced a tool for checking broken links.
