Parsing and Stringifying Query Parameters
- whatwg-url:
whatwg-urlprovides a detailed and standards-compliant way to parse URLs, including their query components. It follows the URL specification closely, ensuring accurate parsing and manipulation of query parameters, but it is more complex and lower-level compared toquery-string. - uri-js:
uri-jsfocuses on URI parsing and manipulation rather than query parameters specifically. It provides detailed parsing of URIs, including the query component, but does not offer specialized functions for query string manipulation. It is more comprehensive in terms of URI handling but less focused on query parameters. - url-parse:
url-parseoffers basic parsing of query parameters as part of its URL parsing functionality. It allows access to the query string and provides a simple way to manipulate it, but it is not as feature-rich asquery-stringfor dedicated query parameter handling. - query-string:
query-stringprovides simple functions for parsing and stringifying query parameters. It handles nested objects and arrays, making it easy to work with complex query strings. The API is straightforward, allowing for quick manipulation of query data. - uri-template:
uri-templatedoes not parse or stringify query parameters directly. Instead, it works with URI templates that can include query parameters as part of the template. You would need to combine it with another library for full query parameter manipulation.
URI Validation
- whatwg-url:
whatwg-urlprovides thorough validation of URLs based on the WHATWG URL standard. It ensures that URLs are parsed and manipulated in a standards-compliant manner, making it reliable for applications that require accurate URL handling. - uri-js:
uri-jsincludes robust URI validation as part of its parsing and manipulation features. It checks for compliance with URI standards and can validate different components of a URI, making it suitable for applications that require strict validation. - url-parse:
url-parsedoes not perform comprehensive URI validation. It parses URLs and provides access to their components, but it does not validate the structure or compliance of the URL with any standards. - query-string:
query-stringdoes not perform URI validation. It focuses on parsing and stringifying query parameters without validating the overall structure of the URI or its components. - uri-template:
uri-templatedoes not validate URIs. It works with URI templates but does not provide any validation features for the URIs or templates themselves.
Handling Special Characters
- whatwg-url:
whatwg-urlhandles special characters in URLs according to the WHATWG URL specification. It provides detailed encoding and decoding of characters, ensuring that URLs are processed correctly in compliance with web standards. - uri-js:
uri-jshandles special characters as part of its comprehensive URI parsing and manipulation. It follows URI standards for encoding and decoding characters, but it does not provide specialized functions for handling special characters in query parameters. - url-parse:
url-parsehandles special characters in URLs during parsing and serialization. It follows standard encoding practices, but likeurl-parse, it does not provide extensive features for managing special characters beyond basic parsing and manipulation. - query-string:
query-stringhandles special characters in query parameters by encoding and decoding them as needed. It follows standard URL encoding practices to ensure that characters like spaces, &, =, and others are properly handled when parsing and stringifying query strings. - uri-template:
uri-templatehandles special characters within the context of URI templates. It allows for the encoding and decoding of characters as part of the template processing, but it does not specifically address special characters outside of that context.
Code Examples
- whatwg-url:
Parsing a URL with
whatwg-urlimport { URL } from 'whatwg-url'; // Creating a URL object const url = new URL('https://example.com:8080/path?query=1#fragment'); // Accessing URL components console.log(url.protocol); // 'https:' console.log(url.hostname); // 'example.com' console.log(url.port); // '8080' console.log(url.pathname); // '/path' console.log(url.search); // '?query=1' console.log(url.hash); // '#fragment' - uri-js:
Parsing and Validating a URI with
uri-jsimport { URI } from 'uri-js'; // Parsing a URI const uri = URI.parse('https://example.com:8080/path?query=1#fragment'); console.log(uri); // Validating a URI const isValid = URI.validate('https://example.com'); console.log(isValid); // true - url-parse:
Parsing a URL with
url-parseimport Url from 'url-parse'; // Parsing a URL const url = new Url('https://example.com:8080/path?query=1#fragment'); console.log(url); // Accessing URL components console.log(url.protocol); // 'https:' console.log(url.host); // 'example.com:8080' console.log(url.query); // '?query=1' console.log(url.hash); // '#fragment' - query-string:
Parsing and Stringifying Query Parameters with
query-stringimport { parse, stringify } from 'query-string'; // Parsing a query string const parsed = parse('?name=John&age=30&hobbies[]=reading&hobbies[]=coding'); console.log(parsed); // Output: { name: 'John', age: '30', hobbies: ['reading', 'coding'] } // Stringifying an object to a query string const queryString = stringify({ name: 'Jane', age: 25, hobbies: ['music', 'art'] }); console.log(queryString); // Output: 'name=Jane&age=25&hobbies[]=music&hobbies[]=art' - uri-template:
Using
uri-templateto Create a URI from a Templateimport { parse, expand } from 'uri-template'; // Defining a URI template const template = parse('https://api.example.com/users/{id}/posts{?sort,page}'); // Expanding the template with variables const uri = expand(template, { id: 42, sort: 'date', page: 1 }); console.log(uri); // Output: 'https://api.example.com/users/42/posts?sort=date&page=1'
