The issue I had with it is that I had to write the schema definitions and the typescript interfaces. If you are fine with writing everything two times, one for the Schema and one for the Document as Typescript Interface, maybe this is the best way to go!
- NestJS + TypeORM is where you can actually use TypeORM with MongoDB; however, I do not recommend this. If you want to learn more, I would ask you to read this blog post.
- NestJS + Typegoose — basically, it uses your domain objects to get the schema from them. And this is what this post is all about. There is a lot of documentation on how you can achieve that; however, I didn't like most of it; it just looked like too much code. On top of that, ALL tutorials ALWAYS include using a DTO class, and I don't see a reason to use DTO classes at all in 99% of the cases. DTOs are great, don't get me wrong, there are many pros of using DTOs, but none of the tutorials on the internet actually explains why they want DTOs, and in fact, none of them need DTOs so I would like to write the easiest straightforward way with NestJS + MongoDB + and TypeGoose.
So, first of all, we will install NestJS CLI, NestJS is very, very similar to Angular, and even if you don't like Angular, trust me, you will like NestJS since I am actually the same! For a great beginner's tutorial for NestJS, you can read here find. |  Building A Log Analytics Solution 10 Times More Cost-Effective Than Elasticsearch May 19th 2023, 20:36, by Frank Z Logs often take up the majority of a company's data assets. Examples of logs include business logs (such as user activity logs) and Operation and Maintenance logs of servers, databases, and network or IoT devices. Logs are the guardian angel of business. On the one hand, they provide system risk alerts and help engineers quickly locate root causes in troubleshooting. On the other hand, if you zoom them out by time range, you might identify some helpful trends and patterns, not to mention that business logs are the cornerstone of user insights. |  How To Streamline Translation Workflows for Websites and Apps May 19th 2023, 20:25, by Andre Zuber In this fast-paced globalized world, effective communication with everybody is essential.

Information change instruments remove the intricacy of having to physically reformat and change information to have the option to acquire bits of knowledge. Data aggregation, data cleansing, data mapping, and data transformation techniques in combination are essential for all businesses, regardless of size, as we'll see in this section. What Is the Transformation of Data? The process of transforming data from one format to another so that it can be used in several ways is known as data transformation. Information change processes are either basic or complex. Either Python scripts or an extract, transform, load (ETL) tool can be used to complete them. |  Which Is Better for IoT: Azure RTOS or FreeRTOS? May 19th 2023, 19:47, by Carsten Rhod Gregersen Every time an IoT developer starts thinking about choosing an operating system for a new device, there is a myriad of options available to muddy the waters. Many are from well-known providers, like FreeRTOS from Amazon and Azure RTOS from Microsoft, or Zephyr RTOS from Linux, and they each have several features that are aimed at helping IoT developers make the most of their IoT device designs. So how do you know which real-time operating system (RTOS) to choose? Let's start by looking at the roles of RTOS within IoT. Then, we'll discuss how FreeRTOS and Azure RTOS can each fulfill those roles in different ways. |  Connect Snowflake to BigQuery: Two Easy Methods May 19th 2023, 19:35, by Chisom Ndukwu If you've been struggling to find a way to seamlessly connect Snowflake and BigQuery, then this article is a great resource for you.

May 19th 2023, 19:18, by Vipul Gupta As automation testers, many times, we reminisce about what is going on behind the scenes after the URL is passed to the web browser. What happens once the browser requests to load a website, or how does it know whether its request has been accepted and is ready to be fulfilled or not. The answer to these is the HTTP response status codes for the resource APIs executed on the backend for the website. The request goes to the website server, which tells the browser through these numeric codes whether it is successful or not. |  Cypress Test Cases Execution With CI/CD GitHub Action May 19th 2023, 19:01, by Kailash Pathak What Are GitHub Actions? GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that allows you to automate your build, test, and deployment pipeline. You can create workflows that build and test every pull request to your repository or deploy merged pull requests to production. GitHub Actions goes beyond just DevOps and lets you run workflows when other events happen in your repository. For example, you can run a workflow to automatically add the appropriate labels whenever someone creates a new issue in your repository. GitHub provides Linux, Windows, and macOS virtual machines to run your workflows, or you can host your own self-hosted runners in your own data center or cloud infrastructure. |  Best Practices To Create High Available (HA) Applications in Mule 4 May 19th 2023, 18:47, by PRAVEEN SUNDAR In this blog, I would like to share a few best practices for creating High Available (HA) Applications in Mule 4 from an infrastructure perspective ONLY (CloudHub in this article refers to CloudHub 1.0 ONLY).
