This project intends to provide a complete description and re-implementation of the WhatsApp Web API, which will eventually lead to a custom client. WhatsApp Web internally works using WebSockets; this project does as well.
In ES5 your solution is
_.extend(target, [sources]) from Lodash (or any alternative), and ES2015 introduces
Luckily object spread syntax (an ECMASript proposal at stage 3) is a step forward how to manipulate objects, providing a short and easy to follow syntax.
Node.js 8.10 runtime now available in AWS Lambda
The Lambda programming model for Node.js 8.10 now supports defining a function handler using the async/await pattern.
Asynchronous or non-blocking calls are an inherent and important part of applications, as user and human interfaces are asynchronous by nature. If you decide to have a coffee with a friend, you usually order the coffee then start or continue a conversation with your friend while the coffee is getting ready. You don’t wait for the coffee to be ready before you start talking. These activities are asynchronous, because you can start one and then move to the next without waiting for completion. Otherwise, you’d delay (or block) the start of the next activity.
Asynchronous calls used to be handled in Node.js using callbacks. That presented problems when they were nested within other callbacks in multiple levels, making the code difficult to maintain and understand.
Promises were implemented to try to solve issues caused by “callback hell.” They allow asynchronous operations to call their own methods and handle what happens when a call is successful or when it fails. As your requirements become more complicated, even promises become harder to work with and may still end up complicating your code.
Async/await is the new way of handling asynchronous operations in Node.js, and makes for simpler, easier, and cleaner code for non-blocking calls. It still uses promises but a callback is returned directly from the asynchronous function, just as if it were a synchronous blocking function.
Node 8 support for AWS Lambda is here!
If you’re a serverless developer on Lambda, read on for what you need to know about Node 8. Namely: speed, Async/Await, object rest and spread, and NPX.
In this guide I will show you how to use Firebase, React, and Ant Design as building blocks to build functional, high-fidelity web applications. To illustrate this, we’ll go through an example of building a todo list app.
Using the above approach is productive – especially if you have good boilerplate to get you started – but what if you want to build something quickly with nearly zero setup time? Sometimes a mockup doesn’t convey enough information to a client; sometimes you want to build out an MVP super fast for a new product.
