Description

Description

The querystring module has been officially deprecated by Node.js for some time. The replacement recommended is URLSearchParams.

An autofix to convert common operations with the querystring module (ex. querystring.stringify) to their URLSearchParams equivalent would be useful as well.

Fail

import ... from 'querystring';

require('querystring');

Pass

// anything else

Research direction
Examine existing rules in eslint plugin unicorn for patterns. The rule should detect imports of 'querystring' and suggest replacement with URLSearchParams. The autofix will require AST transformations. Look at similar rules like 'prefer node protocol' for reference.
