Description

Since repl.builtinModules is deprecated in Node.js v24.2.0, we should provide a codemod to replace it.

• The codemod should replace all instances of repl.builtinModules with module.builtinModules.
• The codemod should also replace const repl = require('node:repl'); with const module = require('node:module'); (also ESM import statement) if it exists in the file. And if repl is used for something else, don't replace it.
• if the node:repl import is destructured, it should be replaced with node:module destructured import. And it's should not replace the whole import if there are other imports from node:repl that are not builtinModules.

Additional Information

Note that repl.builtinModules is deprecated in favor of module.builtinModules. But module.builtinModules have more api listed than repl.builtinModules, so we need to document that so if the user is using repl.builtinModules to get the list of builtin modules, they should be aware that the list will be different.

Examples

Case 1:

Before:

const { builtinModules } = require('node:repl');

console.log(builtinModules);

After:

const { builtinModules } = require('node:module');

console.log(builtinModules);

Case 2:

Before:

const repl = require('node:repl');

console.log(repl.builtinModules);

After:

const module = require('node:module');

console.log(module.builtinModules);

Case 3:

Before:

const { builtinModules, foo } = require('node:repl');

console.log(builtinModules);

foo(); // does something else

After:

const { foo } = require('node:repl');
const { builtinModules } = require('node:module');

console.log(builtinModules);

foo(); // does something else
