Delete Documents, Drop Collection in MongoDB

Delete Documents, Drop Collection in MongoDB

To delete documents in MongoDB, you can use the deleteOne() or deleteMany() methods. These methods allow you to remove one or multiple documents, respectively. Here’s an example of using the deleteOne() method to remove a single document: db.collection.deleteOne({ _id: ObjectId("your_document_id_here") }); Enter fullscreen mode Exit fullscreen mode If you want to delete all documents, you can use the deleteMany() method: db.collection.deleteMany({}); Enter fullscreen mode Exit fullscreen mode Additionally, you can delete all documents that match a specific condition: db.collection.deleteMany({ your_query_here }); Enter fullscreen mode Exit fullscreen mode To delete an entire collection, use the drop() method: db.collection.drop(); Enter fullscreen mode…

Angular CDK Tutorial: Accordion Module

Angular CDK Tutorial: Accordion Module

An accordion component is a component that has one or more expandable sections within it. It’s pretty common to have the need for this type of thing when building apps in Angular. And, it’s not the most difficult thing to do even if you’re creating your own from scratch but the CDK makes it really simple. In this example I’ll show you just how easy it is. And after we create the accordion using the CDK, we’ll even make it accessible with some ARIA. Alright, let’s get to it! The Demo Application For the example we’ll be working with in…

Pseudocode/Python Project

Pseudocode/Python Project

Hey All. I am writing a program that uses conditionals as well as a while loop. I am running into problems with the while loop. The loop is set to run if the user doesn't enter 'yes' or 'no' when asked whether they would like to make a payment. No matter where I try to place the loop it seems to get stuck if I enter anything other than 'yes' or 'no' then enter either 'yes' or 'no' after the loop. It seems that if I try to catch someone not entering either of the two acceptable entries the program…

GIF to JPG: Transitioning Between Image Formats

GIF to JPG: Transitioning Between Image Formats

What Are the Differences Between GIF and JPG? GIF (Graphics Interchange Format) and JPG (or JPEG - Joint Photographic Experts Group) are two of the most widely used image formats, each serving different purposes and possessing distinct characteristics. GIF - Compression: GIF uses lossless compression, which means no image data is lost, preserving the quality. However, it is limited to a palette of 256 colors, which can restrict its use for detailed images.- Animation: GIF supports animations, allowing multiple frames within a single file, making it ideal for simple animated graphics.- Transparency: GIF supports binary transparency, meaning a pixel can…

Todo App in 3 hours

Todo App in 3 hours

Creating a Todo app with Refine and Supabase This article will cover the technical aspects of how I made a Todo app in a few hours using Refine and Supabase. I tried to take a few detours from the official way of doing things to showcase a few possible ways one can achieve the same result. All the code is available at https://github.com/TheEmi/TodoRefineYou can see an instance of the app running at https://todo-app-rosy-pi-29.vercel.app/ Getting started To begin, we will head to refine.new which is a quick tool for creating the Refine project with the standard integrations already written.

Seamless State Management using Async Iterators

Seamless State Management using Async Iterators

In my recent post about AI-UI, I touched on why I developed the library. I wanted declarative markup I wanted type-safe component encapsulation, with composition & inheritance I wanted a small, fast client-side solution with no complex build process (or any build process!) ...but most importantly... I didn't want to learn a whole new API just to manipulate data I already have in my app In my single page apps, I've got remote APIs and endpoints that supply data. Sure, I might want to do a bit of arithmetic, sorting, formatting, but basically, I want to say to the UI:…

The Importance of Continuous Code Review and Early Security Integration

The Importance of Continuous Code Review and Early Security Integration

In today's fast-paced digital landscape, software development is at the heart of innovation and progress. As businesses and organizations rely more heavily on software solutions, the need for robust, secure, and efficient code has never been greater. This is where continuous code review and early security integration come into play, serving as crucial pillars in the modern software development lifecycle. Continuous code review is the practice of systematically examining code changes throughout the development process, rather than waiting until the end of a project. Early security integration, on the other hand, involves incorporating security measures and best practices from the…

Flashback in GBase 8c for Data Consistency

Flashback in GBase 8c for Data Consistency

Flashback technology in GBase 8c is a crucial method for ensuring global data consistency. It allows for the selective and efficient rollback of a committed transaction's effects, facilitating recovery from human errors. Prior to the introduction of flashback technology, recovery from committed database changes was only possible through methods such as backups and PITR, which could take minutes or even hours. With flashback technology, restoring data to its state before the committed changes takes only seconds, and this recovery time is independent of the database size. Flashback supports two recovery modes: MVCC-based multi-version data recovery: This mode is suitable for…
