Most examples I see to do something like this are for S3. Although the APIs are the same it can still be a confusing difference. This is a basic example that includes both a client and a server.
The server uses Node.js and Express and the client is built with React (specifically using create-react-app).
I've also written a companion article for this repo.
Install dependencies in both server/ and client/ using npm:
$ npm install
In the server repo you'll need to update config.js
to include your own Digital Ocean Spaces details. You can generate tokens at https://cloud.digitalocean.com/account/api/tokens
You'll need a DO account and a Space (which costs $5 a month).
You'll also need to have CORS configured for your space. You can find this under the settings for your space. A quick and dirty setup would be:
Origin: *
Allowed Methods: PUT
Allowed Headers: *
This will allow PUT requests from anywhere with any headers so long as the request includes a valid access token.
From the server directory run:
$ npm start
The server runs by default on port http://localhost:4000
From the client directory run:
$ npm start
The client runs by default at http://localhost:3000
