Node.js LTS
Why MagmaLabs for Node.js
Node lets one team move fast from database to browser. We add the structure, typing and observability that keep it fast as the product grows.
02
Built for concurrency
Non-blocking I/O, queues and caching designed up front, so real-time and high-traffic features stay fast under load.
03
Full stack, one team
The same engineers build the React, Next.js or React Native client on top of the API, so nothing waits on another vendor.
04
Tests and tracing
Vitest, contract tests and OpenTelemetry tracing in CI from week one. You see problems before your users do.
Our Node.js services
APIs, real-time features and the integrations and upkeep around them.

FAQ
Something else? Email hello@magmalabs.io.
Is Node.js a good choice for our backend?
For APIs, real-time features and products with a JavaScript or TypeScript frontend, yes. One language across the stack shares types, tooling and talent. For heavy CPU work like data science or media processing, we pair Node with Python or a dedicated worker.
NestJS, Fastify or Express: which should we use?
NestJS for larger teams that want structure, modules and dependency injection. Fastify when performance and a lean core matter. Express for existing codebases, which we keep or migrate gradually rather than rewrite.
Can you upgrade an old Node.js codebase?
Yes. We audit Node and package versions, add tests around the riskiest paths, then move to a supported LTS in steps while your team keeps shipping.
Can you migrate our JavaScript code to TypeScript?
Yes, file by file. TypeScript runs alongside JavaScript, so we tighten types incrementally instead of freezing development for a rewrite.
Can your Node.js developers join our team?
Yes. Through Team Embed, senior Node.js engineers join your Slack, standups and repo, work U.S. hours and follow your process. Monthly, with 30 days notice, starting in 1 to 3 weeks.
Who builds the frontend?
We do, if you need it. The same team builds React and Next.js web apps and React Native mobile apps on top of your Node API, with shared types between them.
How much does Node.js development cost?
Node.js engineers through Team Embed start at $8,500 per engineer per month. Scoped projects such as a new API, an integration layer or a real-time feature are quoted as a fixed price after scoping. If your app was built fast or with AI tools, the Production Readiness Audit is a fixed $4,900.
