I also show examples using the OpenSSL commandline tools and ursa in node.js.

Today we add the ability to upload images as binary data via NodeJS and Express to our MongoDB database. We will use Mongoose models and to represent one to many relationships and using the populate function to expose the children models. We will be using the Multer package to handle the multi-part file data which holds the image data and finally we will expose the public/uploads folder outside of corse protection so these images can be served via our nodejs server. If you would like to vote on what I cover next, do so here! https://reactu.io/polls/newest The code for this episode is on github: https://github.com/react-u/026-uploading-binary-files-and-images-express-nodejs-cors ❤ Help keep ReactU free by donating to the project: ----------------------------------------------------------------------------------- ▶ Bitcoin: 1LxbzzxogbJrxT8d7e2CpnxQRezpzSJejq ▶ Patreon: https://www.patreon.com/reactu ▶ Live Mentorship: https://codementor.io/marktellez Patreon supporters can earn up to a 30% discount on my live mentoring services at https://codementor.io/marktellez ! ❤ Screencast info ----------------- ▶ Length: 38:34 minutes ▶ Skill level: Intermediate ❤ What you will learn --------------------- ▶ * Exposing a public folder outside of CORS to serve images ▶ * Using Multer to allow multi-part form data into our json api ▶ * Setting up our Mongoose models to have a one to many relationship ▶ * Using Postman to test our json API endpoints
