It is therefore advisable to use require for loading static JSON files such as configuration files that do not change often. Do not use require if the JSON file you load keeps changing, because it will cache the loaded file and use the cached version if you require the same file again. Additionally, CSS is crucial in creating responsive websites that adapt to different screen sizes and devices. It also allows for consistent and uniform styles across different pages on a website and helps in making websites accessible to users with disabilities.
Step 1: Create a file that ends with a .js extension
- I assume the application does this via one of above-mentioned methods.
- Placing scripts at the bottom of the element improves the display speed, because script interpretation slows down the display.
- The difference between the two is that writeFile is asynchronous while writeFileSync is synchronous.
- Important here is to realize that these modules are being cached, so if you require() a certain module twice it will return the already created module.
Component-driven development is an excellent strategy to accelerate the development of frontends and user interfaces. We cannot stress enough the importance of multimedia such as images, infographics, and videos in development. However, the size of images affects the overall performance of an application and its usability.
The difference between the two is that readFile reads the file asynchronously while readFileSync reads the file synchronously. Therefore, readFileSync blocks the event loop and execution of the remaining code until all the data has been read. This article is a comprehensive guide on how to use the built-in fs module to read and write data in JSON format. We’ll also look at some third-party npm packages that simplify working with data in the JSON format.
