Upload Ghost local storage images to Cloudinary

Ghost content update

  1. Export your Ghost content (aka backup)
  2. Open in an editor that support Regex find/replace
  3. Search for:
/content/images/\d{4}/(\w{3}|\d{2})/
  1. Replace by:
http://res.cloudinary.com/{cloud-name}/image/upload/{transformations}/{folder}/

It is adived to create a named tranformation in Cloudinary and use it in the URL so if you want to change what the transformation does, you can simply update the named transformation in Cloudinary instead of updating all your Cloudinary URL in your blog.

// Usage:
// $ npm i --no-package-lock --loglevel=error cloudinary glob
// $ CLOUDINARY_URL=cloudinary://xxxx node ghost-image-to-cloudinary.js
const cloudinary = require('cloudinary').v2,
path = require('path'),
glob = require('glob'),
basedir = 'content/images/',
dups = [],
gopts = {
use_filename: true,
unique_filename: false,
overwrite: false
},
getTags = (name) => {
const dpr = name.match(/@(\d)x(?!.*@\dx)/);
return dpr ? ['blog', `dpr${dpr[1]}`] : ['blog', 'dpr1'];
},
findDups = (f, cb) => {
f = path.parse(f);
if (dups.indexOf(f.name) >= 0) {
console.error(new Error(`Found dup with ${f.name}`));
return;
}
dups.push(f.name);
cb(f);
},
upload = (f, cb) => {
const fopt = Object.assign({}, gopts, {
public_id: path.join('blog', f.name),
tags: getTags(f.name)
});
// console.log(fopt); cb(); return;
cloudinary.uploader.upload(path.join(f.dir, f.base), fopt, (err, res) => {
if (err) { throw err; }
console.log(res.url);
cb();
});
};
glob(path.join(basedir, '**/*.jpg'), (err, files) => {
if (err) { throw err; }
let i = 0;
const run = (files) => {
return findDups(files[i], (f) => {
return upload(f, () => {
i++;
if (i < files.length) {
run(files);
}
});
});

});
