valid-url.isWebUri is a function that checks whether a given string is a valid web URI or not.

How does valid-url.isWebUri work?

valid-url.isWebUri is a function that can be used to check whether a given string is a valid web URI or not. The function takes one argument, which is the string that you want to check. The function returns true if the string is a valid web URI, and false otherwise. To determine whether a given string is a valid web URI, valid-url.isWebUri uses a regular expression to match against the string. The regular expression is based on the syntax for a web URI as defined in RFC 3986. Here are some examples of how valid-url.isWebUri can be used: javascript Copy code {{{{{{{ const validUrl = require('valid-url'); console.log(validUrl.isWebUri('https://www.google.com')); // Output: true console.log(validUrl.isWebUri('http://example.com/')); // Output: true console.log(validUrl.isWebUri('www.google.com')); // Output: false In this example, we use valid-url.isWebUri to check whether three different strings are valid web URIs. The first two strings are valid web URIs, and so validUrl.isWebUri returns true for each of them. The third string is not a valid web URI, and so validUrl.isWebUri returns false for it. Overall, valid-url.isWebUri is a useful function for validating web URIs in JavaScript, and can be used to ensure that user input is in the correct format before being used in a web application.

const validUrl = require("valid-url");

const url1 = "https://www.google.com";
const url2 = "http://example.com/";
const url3 = "www.google.com";

console.log(validUrl.isWebUri(url1)); // Output: true
console.log(validUrl.isWebUri(url2)); // Output: true
console.log(validUrl.isWebUri(url3)); // Output: false

In this example, we first import the valid-url module using require. We then define three different URLs: url1, url2, and url3. We then use validUrl.isWebUri to check whether each URL is a valid web URI. For url1 and url2, which are valid web URIs, the function returns true. For url3, which is not a valid web URI, the function returns false. Overall, valid-url.isWebUri is a useful function for validating URLs in a Node.js application.
