New to Node.js?
What is Node.js?
Node.js 26 has been the Active LTS line since October 28, 2026. Node.js 20 reached end of life in April 2026.
It is stewarded by the OpenJS Foundation, with frameworks such as Express, NestJS and Fastify built on top.
Where you are starting from
Where are you with Node.js?
What state is your Node.js back end in today?
- Path 01Not built yet
A new Node.js build
You need an API, a real-time service or an integration on a current LTS.
- Design agreed before code
- TypeScript and a framework chosen for fit
- Tests and pipeline from the first sprint
- Path 02Built by a team that left
Taking over a back end
A Node.js service runs in production and the people who built it have moved on.
- Code and dependency review first
- Deploy and run steps written down
- Fixes ranked by risk
- Path 03Running on an old Node.js
Upgrading or modernizing
It works, but runs on Node.js 16, 18 or 20, which no longer get security fixes.
- Packages checked for each version
- Upgrade done in tested steps
- ES modules where they help

02Versioned, documented APIs for web, mobile and partner apps.
Real-time apps
03Live dashboards, chat and notifications that update without a refresh.

- ES modules
- TypeScript
- Express
- NestJS
- Fastify
- Prisma

Node.js upgrades
Which Node.js version should we upgrade to?
Node.js 20 reached end of life on April 30, 2026. Node.js 22 follows on April 30, 2027.
TodayNode.js 16, 18 or 20
- Node.js 26
Move to the Active LTS
Node.js 26 has been Active LTS since October 28, 2026, with support to April 30, 2029.
Best for most services, so the next upgrade is years away.
- Node.js 24
Move to Node.js 24
In maintenance until April 30, 2028, a shorter step when a key package is not ready for 26.
Best for large services with older dependencies.
- ES modules
Modernize the module system
CommonJS code moved to ES modules in the same plan, so current libraries load cleanly.
Best when new packages no longer support require().
How we work with you
How can we work together on Node.js?
Three ways to engage. Each starts with a written proposal agreed before work begins.
- Fixed-scope project
A defined Node.js deliverable, built and handed over.
- We direct the work against agreed milestones
- Priced per milestone in the proposal
- Working code, tests and documentation
- Fits a new API, an integration or an upgrade
- Dedicated team
A Node.js team that runs your back end with you.
- Our lead runs delivery, you set priorities
- Billed on a monthly plan
- Engineers, a lead and testing as one unit
- Fits ongoing product work without an in-house team
- Team extension
Node.js engineers added to the team you already run.
- Your managers direct the day-to-day work
- Billed monthly for each engineer
- Vetted engineers; we handle employment and replacement
- Fits a backlog bigger than your current team
How it runs
How does a Node.js engagement start?
Five steps from the first call to delivery.
- Brief
- Free 60-minute review of your services
- Goals, constraints and access agreed under NDA
- Match or design
- Engineers matched and interviewed by you
- Or a scope and milestone plan written
- Start
- Accounts, repos and environments set up
- Codebase walkthrough and a first task
- Build and review
- Sprints with code review on every change
- Tests and a demo each sprint
- Hand over or continue
- Runbooks and handover sessions
- Or a monthly plan for support
Cost and timing
What it costs and how long it takes
The review is free
A 60-minute architecture review of your Node.js back end setup, with a written plan you keep.
A fixed-scope proposal first
Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.
Timing follows scope
How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.

Three ways: a fixed-scope project with milestones, a dedicated team on a monthly plan, or engineers who join your team. Each starts with a written proposal agreed before work begins.
Yes. They work in your repos, tools and sprint rituals, and your managers direct the day-to-day work. We handle employment, and the replacement terms are written into the contract.
Each engineer passes a technical interview on Node.js, TypeScript and the frameworks you use, a practical coding exercise and a review by a senior engineer. You interview them before anyone starts.
Yes. Node.js connects through the Salesforce REST, Bulk and Pub/Sub APIs, often with jsforce, a community library. The Salesforce CLI itself is a Node.js application.
We work from hubs in Delaware and Sydney and deliver remotely worldwide on your business hours. The agreed overlap with your team is written into the contract.
