Replace deprecated .data property with .body for compatibility with [email protected]

[jamesdesantiago]

Environment details:

OS: Windows 10
Node.js version: v22.12.0
npm version: v10.9.0
gaxios version: v6.7.1

Steps to reproduce

1. Install googleapis or another library that depends on gaxios and uses [email protected]:

   npm install googleapis
   

2. Create a simple script that makes an authenticated request using googleapis:

const { google } = require('googleapis');

async function testGaxios() {
  const auth = new google.auth.GoogleAuth({
    scopes: ['https://www.googleapis.com/auth/cloud-platform'],
  });

  const authClient = await auth.getClient();
  const projectId = await auth.getProjectId();

  const res = await authClient.request({
    url: `https://cloudresourcemanager.googleapis.com/v1/projects/${projectId}`,
  });

  console.log(res.data);
}

testGaxios().catch(console.error);

3. Run the script:

node index.js

4. Observe the deprecation warning in the console:

(node:12345) [https://github.com/node-fetch/node-fetch/issues/1000 (request)] DeprecationWarning: .data is not a valid RequestInit property, use .body instead

Description

The _defaultAdapter method in gaxios passes .data as a property of the opts object to node-fetch. With [email protected], .data is no longer a valid property and should be replaced with .body. This results in the following deprecation warning:

(node:12345) [https://github.com/node-fetch/node-fetch/issues/1000 (request)] DeprecationWarning: .data is not a valid RequestInit property, use .body instead

Suggested Fix

Update _defaultAdapter to translate .data into .body before making the request. Example:

if (opts.data) {
    opts.body = opts.data;
    delete opts.data;
}

This change ensures compatibility with [email protected] and removes the deprecation warning.

Expected Behavior:

gaxios should internally convert .data to .body before passing the options to node-fetch. This ensures compatibility with [email protected] and eliminates the deprecation warning.
