👋🏼Hey!

Next.js and Vercel offer support for multi zones that merge different deployments in a single project. Assigning custom domains to all zone in Vercel is crucial to encourage search engines to index each deployment.

There are two widespread ways of opening an URL with a SwiftUI app, namely custom URL schemes and universal links. Since the latter are not applicable for third-party URLs, I utilize a share extension combined with a custom URL scheme to open third-party URLs in a SwiftUI app.

Creating a list in SwiftUI is pretty simple. To populate lists, we usually refer to other data sources, e.g., an API. This way, the items in the list can easily exceed the available vertical display space which automatically makes the list scrollable. However, the API used as the list’s data source may not return all items that satisfy the corresponding request. Rather, the returned results are paginated where only one of the pages is returned at a time. To enable the user to scroll through the list of all items seamlessly, we refer to the paradigm of infinite scrolling.

In SwiftUI, AttributeGraph precondition failure is a common error that often hints at an underlying issue. In this article, we look at an instance of this error occurring when using Realm's @ObservedResults property wrapper.

Some apps store sensitive user information that requires authorized access. For example, an app may store a user’s first and last name which should not be accessed by any other user. As such, these apps need to integrate with authorized data storage. On iOS, two commonly employed technologies for authentication and authorized data storage are Sign-in with Apple and Realm, respectively.

Realm offers a development mode to conveniently design your app’s data models from its source code. Once the app enters the production environment, updating the app’s data models becomes more involved. This article shows you how to perform such a schema update in a synchronized Realm and iOS.

With GitLab 14.3, the DevOps platform fixed a security vulnerability that enabled an attacker to impersonate a victim while sending arbitrary HTTP requests. Exploiting this vulnerability would allow an attacker to gain maintainer access to a third-party project, for example. This exploit was possible due to a stored XSS vulnerability in the rich representation of Jupyter notebooks. Combining the lack of HTML sanitization with an npm package used by GitLab triggered an arbitrary HTTP request on behalf of the victim, impersonating them.

The data models in a database evolve with the development of a codebase. Hence, applying changes to these data models is a common task of developers. While tools like SQLAlchemy and Alembic come in handy to accomplish these tasks, using Docker for the development process adds another layer of challenges on top. In this article, I showcase the migration of a dockerized MySQL database in Python with the aforementioned tools.

Serving static files like images is an essential ingredient for front-end development. With bundlers such as webpack and Parcel, this task has become as easy as developers could wish for. While this holds for the production environment of a front-end, matters are a little more complicated during development. parcel serve does not copy static files to the output directory during development, leaving developers on the outlook for a custom solution.
