This page provides a list of codemods to help you migrate your code from Node.js v16 to v18.

## `dns-lookup-options-coercion`

In Node.js v18, the [DEP0153](https://nodejs.org/api/deprecations.html#dep0153-dnslookup-and-dnspromiseslookup-options-type-coercion) deprecation reached end-of-life, which means that the `dns.lookup()` and `dnsPromises.lookup()` functions will no longer coerce option values to their proper types. This codemod will help you convert any literal option values to their proper types.

You can find this codemod in the [Codemod Registry](https://app.codemod.com/registry/@nodejs/dns-lookup-options-coercion).

```bash
npx codemod run @nodejs/dns-lookup-options-coercion
```

### Examples:

```diff
const dns = require("node:dns");

- dns.lookup("example.com", { family: "4", all: 1 }, callback);
+ dns.lookup("example.com", { family: 4, all: true }, callback);
```

```diff
import { lookup } from "node:dns/promises";

- await lookup("example.com", { family: "6", verbatim: 0 });
+ await lookup("example.com", { family: 6, verbatim: false });
```

## `err-invalid-callback`

In Node.js v18, the [DEP0159](https://nodejs.org/api/deprecations.html#DEP0159) deprecation was introduced, which deprecated the `ERR_INVALID_CALLBACK` error code in favor of `ERR_INVALID_ARG_TYPE`. This codemod will help you replace any references to the old error code with the new one.

### `crypto-rsa-pss-update`

In [DEP0154](https://nodejs.org/docs/latest/api/deprecations.html#DEP0154), the `generateKeyPair` and `generateKeyPairSync` methods in the `crypto` module deprecated the `hash`, `mgf1Hash`, and `saltLength` options for the `'rsa-pss'` key type in favor of `hashAlgorithm`, `mgf1HashAlgorithm`, and `saltLength` respectively.
