Node.js uses a small number of threads to handle many clients. In Node.js there are two types of threads: one Event Loop (aka the main loop, main thread, event thread, etc.), and a pool of k Workers in a Worker Pool (aka the threadpool). If a thread is taking a long time to execute a callback (Event Loop) or a task (Worker), we call it "blocked".

Web Crypto API functions are generally more generic. How To Calculate Hashes with Crypto. Crypto has a method called createHash which allows you to calculate a hash.

Instead of callbacks it relies on async iteration (for await of) enabling composability features like seamless switching between real-time data streaming and historical data The API reference documentation provides detailed information about a function or object in Node.js. This documentation indicates what arguments a method accepts, the return value of that method, and what errors may be related to that method. It also indicates which methods are available for different versions of Node.js. A: I guess that your point is that if we can or cannot create REST services without using pure Node.JS code, avoiding any extra libraries. If that is the point, I would say that since we are using a node.js library (express.js) that is build with node.js and for node.js, then it is still true that we can build REST services with just Node. The units build on each other, so check out Learn Node.js, Unit 1: Overview of Node.js Learning Path to start at the beginning.

Feb 16, 2015 · How to Encrypt in Node.js and Decrypt in C# Are you trying to send messages to a .NET application from node.js and you want to encrypt them? You can find here a simple example to accomplish it. The Web Crypto API is defined entirely around asynchronous APIs that return promises, while the existing Node.js crypto module uses a combination of synchronous primitives, callbacks and stream APIs. Adopting Web Crypto into Node.js provides an additional promise-based approach that appeals to many developers. WebCrypto Prototype for Node.js This is a partial and experimental WebCrypto implementation for the Node.js platform. Since WebCrypto API is already widely adopted by browsers, there is zero chance of going in the opposite direction and pushing Node's native crypto interface into that world.

Finally, we’re getting to the heart of the matter: creating and calling a new API endpoint that goes out on the Internet to get the current crypto prices. API Key.
