Question 1

Should I use query-string or URLSearchParams for my project?

Accepted Answer

Use URLSearchParams for simple, standard query string operations as it's native, lightweight, and built into browsers. Choose query-string if you need advanced features like custom array formats, explicit type conversion, or URL utilities like pick and exclude.

Question 2

How to parse arrays in query strings with query-string?

Accepted Answer

Use the parse method with the arrayFormat option—for example, set it to 'bracket' for foo[]=1&foo[]=2, 'comma' for foo=1,2,3, or 'separator' with a custom character. Refer to the README for detailed examples with each format.

Question 3

Can query-string handle nested objects in query strings?

Accepted Answer

No, query-string intentionally does not support nested objects to avoid spec inconsistencies and edge cases. For nested data, you must serialize the object to a JSON string and pass it as a value, then parse it separately.

Question 4

How to automatically convert query string values to numbers or booleans?

Accepted Answer

Enable the parseNumbers and parseBooleans options in the parse method, or use the types schema for explicit typing—like defining age as 'number' or flagged as 'boolean'—to ensure values are parsed correctly based on your needs.

Question 5

Is query-string compatible with Node.js?

Accepted Answer

Yes, query-string works in both Node.js and browser environments, providing consistent query string manipulation. It's installable via npm and handles encoding and decoding uniformly across platforms.

Question 6

How to remove specific query parameters from a URL using query-string?

Accepted Answer

Use the exclude method, which allows you to filter out parameters by providing an array of keys or a custom function, returning a new URL string without those parameters while preserving other URL components.
