TechRadar: Node.js Can Help Small Businesses Save Time and Money

Node.js is an open-source runtime environment that lets developers run JavaScript outside a web browser. Its official documentation describes it as an asynchronous event-driven JavaScript runtime. In practice, Node.js does not sit idle while waiting for a database, payment gateway or file to respond; it moves to the next request and returns to earlier tasks when answers arrive. According to the Node.js docs, almost no function in Node directly pauses execution for a response, so the process never stalls.

The bigger advantage for small businesses is the language itself, TechRadar reported. JavaScript was used by 66% of respondents to the 2025 Stack Overflow Developer Survey, while Node.js was used by 48.7%. That gives employers a large hiring pool and allows one language to cover both the storefront customers see and the back end that keeps the business running. The report also said Node.js is easy for smaller teams to maintain because long-term support releases typically receive critical bug fixes for 30 months, and the project advises running only LTS versions in production.

The report outlines seven ways small businesses can use Node.js. It says most small businesses do not need a sprawling tech stack; they need a handful of reliable systems that talk to each other, stay online and do not require a full-time engineer to maintain. Node.js fits because it is strongest at moving data between people, apps and services, according to the report.

One approach is to run the whole web stack on one language. When a website's front end and back end share a language, one developer can work on both, avoiding separate specialists or handoffs between teams. Code for tasks such as form validation can be written once and reused on both sides. TechRadar cites PayPal's move to Node.js, where engineers reported building an app almost twice as fast with fewer people and using 33% fewer lines of code than the Java equivalent. The report says the lesson scales down: fewer moving parts mean fewer billable hours.

Another use is automating repetitive admin work with scripts. Renaming files, compiling sales reports, sending invoice reminders and cleaning up exported CSVs can be handled by short Node scripts rather than full applications. Because Node.js is built for command-line tools and scripts, these jobs can be scheduled to run overnight. The report says a few hours of developer time upfront can claw back several hours of staff time every month, and fewer manual steps mean fewer copy-paste errors in invoices.

Node.js can also connect business apps through APIs. Payment processors, CRM, email and accounting software usually offer APIs, but those apps rarely share data with each other. Node.js treats HTTP as a first-class citizen, with a global fetch() function stable since Node 21, making it suited to syncing a new order to a stock list or pushing paid invoices into accounting books. Instead of paying for a pricey integration subscription, Node services can do the same job for pennies in hosting, and the business owns the logic, the report says.

The report also points to real-time features. Live chat, order tracking, booking availability and instant notifications rely on keeping connections open, which ties up server resources and becomes more expensive as visitors increase. Node's event-driven design handles that work well, and Node now ships with a browser-compatible WebSocket client stable since version 22.4. The report says businesses can build live updates into a customer portal without adding extra infrastructure, and customers who can see order status tend to send fewer emails asking where their parcel is, reducing pressure on support teams.

The report lists plugging AI services into workflows as another option. It says a small business does not need to train its own AI model to benefit from one.
