A web application often needs to communicate with web servers to get various resources. You might need to fetch data from or post data to an external web server or API.
Using client-side JavaScript, this can be achieved using the fetch API and the window.fetch() function. In NodeJS,
NoSQL brought flexibility to the tabular world of databases. MongoDB in particular became an excellent option to store unstructured JSON documents. Data starts as JSON in the UI and undergoes very few transformations to be stored, so we get benefits from increased performance and decreased processing time.
But NoSQL
Working with files is a common task with any programming language. File manipulation requires us to know their location. One of the most fundamental ways to interact with files is to list files in a directory.
In this article, we'll be using Node.js and the built-in fs module
A common development task is reading data from files. A common file format is the .csv format.
While you can read CSV files using the fs module that comes with Node and get the content of the file, in most cases, parsing and further conversion is much easier with
JavaScript is a dynamically typed language, meaning that the interpreter determines the type of the variable at runtime. In practice, this allows us to use the same variable to store different types of data in the same code. It also means that without documentation and consistency, we do not
H2 is a lightweight database server written in Java. It can be embedded in Java applications, or run as a standalone server.
In this tutorial, we'll review why H2 can be a good option for your projects. We'll also learn how to integrate H2 with Node.js by building
In this article, we are going to take a look at what CORS is, how you can configure CORS with Express, and how to customize the CORS middleware to your needs.
CORS is shorthand for Cross-Origin Resource Sharing. It is a mechanism to allow or restrict
Async Hooks are a core module in Node.js that provides an API to track the lifetime of asynchronous resources in a Node application. An asynchronous resource can be thought of as an object that has an associated callback.
Examples include, but are not limited to: Promises, Timeouts, TCPWrap,
