The "defaults" npm package empowers JavaScript developers to handle defaults for their options efficiently. This package is distinct and practical because it doesn't overwrite options if they haven't been defined within the options object. Plus, it supports deep merging of objects while providing strong defense against prototype pollution attacks.
To use the defaults package in your JavaScript application, follow these step-by-step instructions. Firstly, install the defaults package using npm with this command:
npm install defaults
Then, import defaults into your JavaScript file. You can apply defaults to your options objects. Here's an example:
import defaults from 'defaults';
const calculate = options => {
options = defaults(options, {
timeout: {
before: 100,
after: 100
}
});
// Use options as per your requirements
// β¦
}
// β¦
calculate({timeout: {before: 200}});
In this example, the calculate function accepts an options object. If no options are provided, or if certain options are missing, the defaults function will ensure that the options return with defined timeout before and after parameters, hence providing reliable default options.
The documentation for the defaults npm package can be found on the package's GitHub page. Here, you can learn more about its API, installation, usage, and additional features. Importantly, the defaults function accepts two arguments, options and defaultOptions. The options object contains user-provided options, while the defaultOptions parameter hosts the default options to be returned when a value isn't provided in the options object.
