simple-image-server
Command line utility which starts a web server that you can save and query images from. Only supports png images.
So install with
npm install -g simple-image-serverand then you can override the port and place where the files go (default to ~/simple-image-server) for example
simple-image-server -p 3000 -d /some/path/herePhoto route is at /photos/. So for example, you send a POST with a base64 encoded png image to /photos/hello and you can then view it by sending a GET to /photos/hello.png (or just navigate in a browser to it)
Valid photo names are limited to what is considered valid by https://www.npmjs.com/package/sanitize-filename
If you want something to handle more case names and you want to use this just send me an email at [email protected] and we can improve this. The goal here is just to have a simple generic photo upload/download tool. Nothing fancy.
Example html if you're trying to get it to work with this (this server was made to rip webcam images an upload them to this server).
