A simple express server that allows images to be uploaded with Multer and resizes the based on url scheme, resizing is done with the node-steam library.
Http-bearer is used fo validating requests so only registered clients can upload images.
npm i

THROTTLE_CC_PREFETCHER= 20
THROTTLE_CC_REQUESTS= 100

For throttle see options in node-steam.
The app url is used to return a full url after upload.
Images directory defaults to images, if doesn't get created, create it manually.
This will create a database and the first client
npm run init
Run npm (or pm2, or whatever runner you use).
npm run start
For every site create a row in the MySQL clients table. Generate a random token that's safe. Currently there is no interface for creating so create it command line or through an mysql interface like sequelpro or phpmyadmin.
Example with node.js, using node-fetch & form-data. Notice dotenv is used for API values. Pass the access_token that you've generated for the client. (For security make sure it's over HTTPS)
const FormData = require('form-data');
const fetch = require('node-fetch');
exports.upload = function (token, buffer, fileName) {
const form = new FormData();
form.append('image', buffer, fileName);
form.append('field', 'files');
return fetch(process.env.IMAGE_API_URL+ '/image?access_token=' + process.env.IMAGE_API_ACCESS_TOKEN, {
method: 'POST',
body: form,
})
.then(function(res) {
return res.json();
})
.then(function(json) {
//json.url
})
.catch(function(err) {
// handle error
})
}
Example for creating a thumbnail resize and crop:
http://imageserver.com/image/path.png/:/rs=w:350,h:250;cp=w:350,h:250
For all options (resizing, cropping, filter, etc) check node-steam.
