JWT security for a Rust REST API: how to
In this article, we will learn how to implement JWT security for a Rust REST API Server. At the end of this article, we will have a web server that has an endpoint for authenticating users, which will return a JWT. Clients are then able to use this JWT to gain access to the protected endpoint of our API. This article deals with similar concepts as two previous tutorials but combines them into one project. Here are the two previous tutorials: How to build a Rust REST API with warp How to use JWT with Rust: learn the basics here…

Kucoin API with Rust how to get symbol ticker data
In this tutorial, we are going to look at how to get cryptocurrency symbol ticker data from the KuCoin WebSocket Futures API with Rust. We will be using the public WebSocket API and we will connect to it using Rust and the Tungstenite crate. The Symbol ticker data stream sends real-time price data for cryptocurrency futures symbols. At the end of this tutorial we will have a program that can: connect to the KuCoin cryptocurrency futures WebSocket API. retrieve all available cryptocurrency futures symbols from the REST API. subscribe to streams for all the cryptocurrency futures symbols. process incoming WebSocket…
Python backend with JavaScript frontend: how to
In this tutorial, we are going to learn how to build a simple backend with Python and a frontend in JavaScript. For the Python backend, we will make use of the Flask library. This will let us set up the backend with only a few lines of code. The main goal of this article is to demonstrate the interaction between a Python backend and a frontend. So the frontend will be as simple as possible. We will use plain JavaScript, without frameworks. Meaning, this will be a very barebones example UI. The full project’s code can be found on my…
