Imagine your app faces a sudden surge in users. Thousands log in at once. Can your system handle the pressure, or will it crash?

Mocking APIs is a popular practice in software development. An increasing number of developers are reaping the benefits and no longer using their valuable time to spin up duplicate resources. Many mock services do not require account creation, making them easy to use and privacy-friendly. In the rest of this article, we explain what mock APIs are, when you should think about using them, and what solutions are available within the open-source and proprietary markets.

For the last couple of years, Retrieval-Augmented Generation (RAG) architectures have become a rising trend for AI-based applications. Generally speaking, RAG offers a solution to some of the limitations in traditional generative AI models, such as accuracy and hallucinations, allowing companies to create more contextually relevant AI applications.

Testing is a critical aspect of software development, as it ensures your application works as intended and meets quality standards. In Node.js, testing is essential for the early detection of bugs in public endpoints. However, there are many challenges associated with testing in Node. External dependencies, asynchronous operations, and several possible input scenarios make writing tests a daunting task.

In the last few years, there has been a lot of movement around new and exciting PHP testing tools. While this is great news, stepping back a little and understanding the underlying concepts before jumping in is vital to writing great PHP tests. When we talk about testing tools and methodologies, we're referring to automated testing tools. Writing code that tests your PHP apps is a great way to build confidence that your application will behave as you expect.

As a follow-up to our recent Kong Insomnia v10 release that shipped with an unlimited and free Collection Runner and one week after announcing our official SCIM support for automated user provisioning, we're now excited to announce Insomnia v10.1. This release ships with the general availability of the CLI to use the Collection Runner with CI/CD automation, a new in-app invite wizard that simplifies working with collaborators, and many other improvements.

Lambda functions in Python are a powerful way to create small, anonymous functions on the fly. These functions are typically used for short, simple operations where the overhead of a full function definition would be unnecessary. While traditional functions are defined using the def keyword, Lambda functions are defined using the lambda keyword and are directly integrated into lines of code. In particular, they are often used as arguments for built-in functions.

See the GitHub repository for the source code of this article’s example project. Serverless is a popular framework to build serverless apps using AWS Lambda on the Node.js runtime. Serverless automatically orchestrates necessary resources on AWS and can scaffold a basic project for you that you can build up on. You can solely focus on your application’s core logic, development, and your Lambda functions.
