Custom Node.js development
Low-code is the right tool until it isn't. Some workflows have branching logic that turns into a 60-node spaghetti diagram, or a transformation that's clearer as 20 lines of TypeScript than wired up in a canvas. Some volumes simply outgrow the free Power Automate plan.
What's included in Custom Node services · code-first.
When that's where you are, we write Node.js services. Same requirement study up front, same observability, same audit trail, just in code that can be read, versioned, and unit-tested.
Engineering teams who already have a code-first culture, or non-engineering teams whose automation needs have outgrown what low-code can handle: high message volume, complex transformations, multi-step API orchestration, or strict data residency requirements.
- 01
Scheduled jobs
Cron-driven jobs for daily reconciliation, monthly invoicing, dunning, expiry checks, with retries, dedupe, and email alerts on failure.
- 02
Event-driven workers
Queue workers that respond to webhooks or DB changes, with idempotent processing and dead-letter handling for the messages that just won't process.
- 03
API orchestration
Chain multiple third-party APIs together with retry, timeout, and rollback. The place Power Automate gets brittle and code stays predictable.
- 04
Business logic in pure TS
Calculations, allocations, splits, rule engines, all written as testable pure functions, with unit tests that catch regressions before deploy.
- 05
Self-hosted
Deploys to Railway, AWS, your VPC, or any Docker host. No SaaS dependency you didn't approve. Logs and metrics in tools you already pay for.
- 06
MIT-licensed dependencies
We use the same handful of well-maintained, MIT-licensed libraries across projects. No surprise commercial licenses six months in.
From manual jobs to tested Node.js services.
Measure volume and logic
We document the job as it runs today: its inputs, its volumes, its branching rules and the systems it touches. If Power Automate would handle it well, we tell you. When code is the better fit, the scope and the hosting target are agreed in writing.
Write and test logic
We write the rules as pure TypeScript functions with unit tests, then wrap them in queue workers or scheduled jobs with retries, dedupe and dead-letter handling. Test runs use real sample data, so the output can be compared line by line with the manual result.
Deploy and observe
We deploy to your chosen host with logs, metrics and tracing wired into the tools you already use, plus alerts on failed runs. A written runbook explains how to re-run each job, and we stay on for dependency updates and new jobs.
Questions about Custom Node services · code-first.
- Can a Node.js service take over manual jobs like daily reconciliation and monthly invoicing?
- Yes. Scheduled jobs for daily reconciliation, monthly invoicing, dunning reminders, and expiry checks run on a timer with retries, dedupe, and an email alert if a run fails. Allocations, splits, and rule engines are written as pure TypeScript functions with unit tests, so the logic someone used to apply by hand in a spreadsheet is applied the same way every time, and can be checked.
- Can a custom Node.js service connect Tally, Razorpay, SAP B1, and Microsoft 365?
- Yes. That is API orchestration, and it is where low-code tends to get brittle. A Node service chains calls to Tally, Razorpay, SAP Business One, Microsoft Graph, or WhatsApp with retry, timeout, and rollback, while queue workers respond to webhooks with idempotent processing. Messages that will not process go to a dead-letter table instead of disappearing. It deploys to Railway, AWS, your own VPC, or any Docker host.
- How do you decide between low-code and a custom Node.js service?
- In the requirement study. We document the workflow, its volumes, and its branching with your team first. If the logic would become a 60-node diagram in a canvas, the volume outgrows your Power Automate plan, or data residency rules apply, we recommend code. If Power Automate fits, we say so. Either way, the scope, timeline, and cost are agreed in writing before anything is built.
- Who monitors a custom Node service once it is running?
- Every service ships with structured logs, metrics, and tracing through OpenTelemetry, sent to tools you already pay for, plus email alerts on failed jobs. We document how each job runs and how to re-run it, and walk your team through that before go-live. After launch we stay on for support, and a maintenance retainer covers dependency updates, security patches, and new jobs as your volumes grow.
