Uploading images to ghost Admin-API

Developer help

@Hailst0rm Here’s code I wrote that works for me. I confirmed it returns a successful response and that the file is indeed on the file system after the upload.

Here I don’t send the Content-Type as I advised above.

import * as fs from 'node:fs/promises';

// Construct the token from the key exactly as Ghost would.
import keyToToken from '@tryghost/admin-api/lib/token.js'
const token = keyToToken(key, '/admin');

const key = 'ADMIN-KEY-FROM-GHOST';

const imagePath = '/home/mark/Downloads/face.png';
const filename = 'face.png';
const settings = {
  url: 'http://127.0.0.1:2368',
};
 
const fileContent = await fs.readFile(imagePath);
			const contentType = "image/png"
			const fileBlob = new Blob([fileContent], { type: contentType });
			const formData = new FormData();
			formData.append("file", fileBlob, filename);
			formData.append("purpose", "image");
			formData.append("ref", imagePath);


      let response;
			try {
				response = await fetch(`${settings.url}/ghost/api/admin/images/upload/`, {
					method: "POST",
					headers: {
						// "Content-Type": "multipart/form-data", // Don't include!
						Authorization: `Ghost ${token}`,	
					},
					body: formData
				});
     }
     catch (err) {
        console.error("ERROR",err);
     };

     console.log(await response?.json());

That produces this output for me:

{
  images: [
    {
      url: 'http://localhost:2368/content/images/2023/09/face.png',
      ref: '/home/mark/Downloads/face.png'
    }
  ]
}
