Perhaps the response should not return raw HTML:

# curl https://simplekv.com/path/to/key2

<html><body><h1>Well, this seems safe...</h1></body></html>

Thanks for your feedback! I see input sanitation as a double-edged sword: it could potentially prevent some misuse of the service (since it's 100% anonymous), but then ultimately you're the "owner" of your keys (though they're in reality public) and you should be able to write whatever you want in them.

I guess this argument could also be applied to Pastebin? Should it be returning raw HTML if asked to?

The "Content-Type" HTTP header is "text/html; charset=utf-8", you could make it "text/plain; charset=utf-8" to prevent HTML from being parsed.

Have you looked up cloudflare kv store? It might just be what you want https://developers.cloudflare.com/workers/runtime-apis/kv/

I was looking for something like this numerous times when working on network automation. Is it open source?

re6tor 4 years ago | |

I'll open source it in the coming weeks. Feel free to e-mail me: simplekv at protonmail dot com

Interesting to see how you implemented this. I've created a similar service like this for internal use at a startup I'm working on. The basic idea is the same but I also implemented key deletion (HTTP DELETE) on top of read and write.

I read in one of the comments you're using Flask on the backend, are you storing the key/values in a SQL database? My backend is written in Go and data is serialized to disk in a binary format.

edit: I just saw that you also implemented a delete feature, my bad for not reading all the examples carefully ;-)

Are you planning to accept donations to keep this sustainable? This is actually really exciting, nobody has done anything like this in a long time, the last similar project seems to have gone down.

I'm using Jami's OpenDHT which provides a web gateway API to get and set things, maybe something like that could serve as a backend?

Thank you for your feedback! For now, I wanted to gauge interest and/or traction in such a service. I will definitely add a Donate button in it once the backend starts to max out the VPS where it lives.

As for the backend, it's a Flask-based API. I'll look into your suggestion though!

Would it be possible to require a key within a different url parameter? That way, one would need to know both the name and the api key of the field to edit/delete it? A key would be generated and returned in response to the initial creation request.

I'll see how to integrate such a feature in SimpleKV so that it keeps being simple. I like the idea a lot, thanks!

Good MVP. I wonder where this will lead.

re6tor 4 years ago | |

Thanks! My use case was very specific, but the concept is so simple I was wondering what people would do with it.

Be careful. These things tend to morph, mutate and become turing-complete. If it grows an emacs step back quietly and slowly. Just remember to feed it plenty of parentheses and you'll be fine.

Nice concept, very useful for some test cases
