Connect once, exchange everywhere.

Since April 2022 I’ve written most of DDEP’s Node.js code: projects and integration items per company and environment; inbound connections over API, email, FTP / SFTP and schedules; mapping profiles with spreadsheet-style formulas, filters and validation; outbound delivery through BullMQ queues; and the history, diff and alerting tools the operations team uses every day. The product is live as DynamicLink at a4appz.com.

Key features

Connect, map, monitor.

Node.js with Express and EJS, MongoDB, BullMQ, HyperFormula, node-cron, FTP / SFTP clients and Nodemailer, deployed with Docker, Jenkins and Kubernetes. The images are diagrams, not screenshots.

Mapping & formulas

Mapping profiles turn one system’s JSON or XML into another’s, with spreadsheet-style formulas, global variables and default values.

Example mapping profile: source fields mapped to target fields directly, through formulas or through a global variable

Connections

Items receive data through dynamic API endpoints, mailboxes, FTP / SFTP polling or schedules, and deliver it to APIs, files or email through job queues.

Connection types: REST API, email and FTP / SFTP in and out, JSON, XML, schedules and webhooks

Monitoring & alerts

Inbound and outbound history, diffs between runs, cURL replay, exceptions and email failures, plus alert policies that notify by email or webhook.

Monitoring tools: inbound, outbound and diff history, cURL replay, exceptions, email failures, alert policies and conditions, email and webhook alerts
