We started this tutorial with the aim of learning how to build a backend application using Express, Postgres, Cloudinary, Github and Heroku. In contrast with a website’s frontend, where visitors see and interact with the page, the backend is the part of the website that visitors have no direct interaction with. The backend is where data, like account information, progress in a video game, or items in a shopping cart, are stored in a database. It’s also where code listens for requests from the frontend, and sends back responses when necessary. This code is often referred to as server-side code, and is necessary to have a deeper engagement with users. Here’s a more complete write-up on the best backend programming languages.
It follows a “Convention over Configuration” approach for automatically assigning value without requiring user intervention. Multiple configuration files are utilized by software systems like Java web application frameworks, with each having multiple settings. Convention raises productivity as users are not required to assign time for config file setup. Backend frameworks are server-side frameworks designed to make tasks easier for developers.

So you’ll want to start by cloning this project if you don’t already have it. To achieve all of this, we will be using Express (a Node.js framework), Postgres , Cloudinary , GitHub (for version control/storage) and Heroku . Integrate JavaScript asynchronous actions with Velo to create a backend.
But when you start picking up speed, I recommend that you switch to a cloud provider. This takes away all the nice tools from cPanel that you used to manage files and folders on servers. But at the same time, it will challenge you to level up your skills a lot.

Application data should not be modified here ; it is the job of the classes’ methods of the Domain layer. However, we catch exceptions and use object methods to apply the right business rules. If you’re starting from zero, it will probably take you anywhere from 9 months to 2 years to learn back-end development thoroughly enough that you can land an entry-level position. Of course, it will be different for everyone, but if you can put in a good 10 hours each week, I think that’s a solid estimate. The good news is, that’s faster and cheaper than going back to university for 4 years. This should either have a front-end that contacts it, or documentation that can get users using it with a Postman client, cURL, etc.
- The Docker platform allows development teams to set up lightweight independent environments known as containers and use them instead of virtual machines to deploy applications.
- This article will explore the use of JavaScript for the backend and share some valuable tips for the same.
- In the /web/ directory, create a new file called qr-codes-db.js.
- The framework also provides a bunch of unique features like spring web service, data access framework, etc. that make Spring a great choice for any backend developer to learn.
- ExpressJSis a fast, lightweight, and flexible web application framework based on Node.js.
- It is also relatively simple to learn, making it a good choice for those just getting started in backend development.
Render is a cloud-based platform that simplifies the process of deploying and hosting web applications. It positions itself as a Heroku alternative with easy usage, better pricing, and simple UI. As a backend development tool, it frees your time and mental space by taking care of all your backend stuff and allowing you to spend more time on business and users’ needs.
MongoDB Atlas is a hosted MongoDB service option in the cloud which requires no installation overhead and offers a free…
TheDependency Injectorlibrary is well designed and provides everything you need to define all your services, inject them and even load configurations. Methods of these classes can return Domain objects, states («something went wrong», «no problem here», «only steps 1 and 3 worked»…), or nothing. Follow these steps in order — there are plenty of places you can learn back-end online effectively, some of the resources are paid, and some are free. If you’re looking to get rich quick or take shortcuts, please stay away. We are all about building solid foundations that lead to successful careers. In this article, we will learn all the essentials of Core JavaScript.
Small Business OwnersSmall Business Owners Divi makes it easy for anyone to build their own website. © 2023 WeAreDevelopers – Connecting software developers with top employers worldwide. Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the «When inside of» nested selector system. Spring is a lightweight framework that provides support to various other frameworks like Struts, Hibernate, Tapestry, etc, and is used on millions of computers today. Any fairly complex dynamic website that is packed with features is almost impossible to create without using JavaScript with such ease.

Postman features include converting API to code, various HTTP methods support, and many others. It streamlines collaboration for a backend development team, facilitating building a Continuous Integration/Continuous Delivery (CI/CD) pipeline and test automation. The role of the web server in an application backend is very significant as well.
But we also want to get rid of the record we have in our Postgres database. Back in your project directory, install the node-postgres and make-runnnable (npm i make-runnable) packages. It will be able to store a record of an image in the database, get the image’s record back from the database, update the record, and even delete the record completely as the case may be. In short, maintaining and troubleshooting code is easier when it’s organized. To call the function from the frontend, an import statement is needed. Import allows the multiply() function from the aModule.jsw file to be called.
Python programming language is widely used for machine learning as it is one of the easiest… Node.js is used to build I/O-intensive applications such as video streaming sites and online chatting applications, among many others. Numerous established tech giants and newly formed start-ups use the Node.js framework in their operations. As mentioned, there are many different JavaScript frameworks available which can make backend development simpler and more efficient.
Developed by James Gosling, this ancient language of the web and beyond is a stable choice for many applications and platform development projects. Back-end development tools make sure that the software engine of the website operates as expected, and that all of the bits of code talk to each other properly. Becoming an agile web developer means learning how to operate and function in a variety of web ecosystems that employ both back-end and front-end code.
