Frequently Asked Questions
What is Node.js, and why should I use it for my web project?
Node.js runs on JavaScript but works server-side. That means your site or app can handle lots of users at once, without slowing down. It’s great for building fast APIs, chat features, or anything real-time. If your project needs speed, flexibility, and fewer moving parts between front-end and back-end—Node.js fits.
How do I choose the right Node.js development company in Kolkata?
Skip the pitch deck. Talk to the actual team that’ll touch your code. See if they ask the right questions—not just about features, but what the product is supposed to do. A good agency will walk through edge cases, mention scale, and break down trade-offs clearly. That’s how you know they’ve built more than demo projects.
Can Node.js be used for both web and mobile app development?
Yes. It’s commonly used as the backend for mobile apps, especially when you need data
syncing or real-time notifications. It plays well with mobile frameworks like React Native. So
even if the app is native, Node.js might be doing all the behind-the-scenes work—fetching data,
pushing alerts, processing users.
What is the cost of developing a Node.js application?
Pricing depends on what the app actually does. A single-purpose tool with clean logic won’t
break the bank. Start adding logins, dashboards, automation, or custom integrations—and the
time (and cost) rises. We don’t send quotes until we’ve talked through what’s needed and
what’s not. That way, it’s not guesswork.
How long does it take to build a Node.js-based solution?
If it’s straightforward, something functional can be ready in 6–8 weeks. For more complex
builds, 3–5 months is realistic. But even long projects don’t stay silent. We work in phases, roll
out parts as they’re ready, and keep feedback loops short. You see progress as it happens—not
just a final link in your inbox months later.
Why should I choose Plan D Media for Node.js development?
Our builds aren’t stitched together from Stack Overflow. Every line is part of a larger strategy.
Some teams talk tech specs—you’ll hear ours asking what kind of users you expect, or what
tasks need to happen instantly. That’s because we don’t just care how things run. We care
who’s using them, and why they’ll keep coming back.
