Measuring performance provides an important metric to help you assess the success of your app, site, or web service. For example, you can use performance metrics to determine how your app performs in comparison to a competitor or you can compare your app's performance across releases. The metrics you choose to measure should be relevant to your users, site, and business goals. They should be collected and measured in a consistent manner and analyzed in a format that can be consumed and understood by non-technical stakeholders.
Load testing is a great way to grab insights about how your application runs under heavy load, how all services interact, and to plan production capacity accordingly.
Bottlenecks can slow down an application significantly.
There are many third-party tools available for profiling Node.js applications but, in many cases, the easiest option is to use the Node.js built-in profiler.
NodeJs single-threaded nature is by default using a single core of a processor. Therefore NodeJs introduced a cluster module to spawn processes. “Cluster” was introduced to scale an application execution on multiple processor cores by creating worker processes. Worker processes share a single port, therefore, requests are routed through a single port.
DRY and KISS are software design principles, they are about clean code.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
