Ecosystem and integration

  • Web servers & connectors: IIS, Apache/Nginx Reverse proxy, Tomcat config, AJP hardening.
  • Auth & SSO: SAML, OAuth2/OIDC, JWT, LDAP/AD.
  • Docs & email: cfdocument & pdfg, cfspreadsheet, cfmail Best practices (SPF/DKIM).
  • Monitoring/APM: FusionReactor, New Relic, SeeFusion; alerting & SLAs.

Professional profile

  • Communicate with non-technical stakeholders; triage tickets; write clear docs.
  • Modernize legacy code and manage Technical debt with minimal disruption.
  • Estimate, prioritize, and own projects end-to-end.

Step-by-Step Action Plan

1) Choose your platform path: Adobe CF, Lucee, or both

  • Enterprise/government → Adobe CF (Licensing/support).
  • Open-source/containers → Lucee + CommandBox.
  • Practical: Spin up both in Docker; compare Admins, datasources, mappings, schedulers.

2) Set up a productive local environment

  • VS Code + CFML extension; add GitLens, REST client, Docker, Test Explorer.
  • Install CommandBox. Start servers: box server start cfengine=adobe@2023 or cfengine=lucee@5.4.
  • Create a ForgeBox account. Install coldbox, testbox, qb.

3) Learn CFML fundamentals the modern way

  • Master Application.cfc, per-app mappings, session/timeouts, this.javaSettings.
  • Prefer CFScript for logic; tags where they shine (cfquery with cfqueryparam, cfdocument).
  • Practical: Build a Task API (GET/POST/PUT/DELETE), return JSON, validate input, add TestBox specs.

4) Connect to databases and write performant SQL

  • Practice on PostgreSQL or SQL Server; normalize, index, read plans.
  • Use cfqueryparam everywhere; learn queryExecute().
  • Practical: Filtering/sorting/pagination with LIMIT/OFFSET; index common filters.

5) Adopt an MVC framework and DI early

  • Add ColdBox + WireBox DI.
  • Split handlers/services/views; use interceptors for logging/security.
  • Practical: Move Task API into a ColdBox module; expose routes in coldbox.cfc.

6) Build and consume APIs securely

  • Version your API (/api/v1); env-driven config/secrets.
  • Implement OAuth2/OIDC; prefer JWT for stateless APIs.
  • Practical: Rate limit via interceptor + CacheBox; sanitize output with encodeForHTML/encodeForJavaScript.

7) Add automated testing and CI

  • TestBox unit & integration tests; optional BDD.
  • GitHub Actions/GitLab CI to run tests/lint on each push.
  • Practical: Workflow spins up DB + Lucee, runs TestBox via CommandBox, posts coverage.

8) Containerize and deploy with confidence

  • Use official Adobe CF/Lucee or CommandBox images.
  • Externalize config with env vars & secrets managers.
  • Practical: Dockerfile + docker-compose (app + DB + Redis), /health checks.

9) Instrument, monitor, and tune

  • Add FusionReactor to staging/prod; alert on errors/latency.
  • Tune JVM (G1GC default); centralize logs (ELK/EFK).
  • Practical: Offload heavy cfdocument to pdfg or async jobs with cfthread/queue.

10) Learn admin and security hardening

  • Study Adobe Lockdown guide. Disable RDS, restrict CFIDE, disable Debugging in prod.
  • Cookie flags: Secure/HttpOnly/SameSite. Rotate session IDs on login.
  • Practical: Read-only DB user for app; separate user for migrations.

11) Modernize Legacy code methodically

  • Wrap legacy modules; add tests before refactors.
  • Migrate to Application.cfc; reduce page-level tags.
  • Replace homegrown utils with ForgeBox packages (qb, Quick, cbsecurity).
  • Practical: Refactor a large .cfm into handler + service + view; add TestBox coverage.

12) Keep pace with community and roadmap

  • Track Adobe CF hotfixes & Lucee 5.x → 6.x releases; check support matrix before upgrades.
  • Follow Ortus Solutions, CFML Slack, Lucee Google Group; attend Adobe CF Summit, Into the Box, CFCamp.
  • Practical: Quarterly dependency/engine updates + staging smoke tests.

Common mistakes and How to Avoid Them

  • Skipping cfqueryparam Risk: SQLi & poor plan caching. Fix: Make it mandatory; lint in reviews.
  • Debugging enabled in production Risk: Data leaks. Fix: Per-env configs; startup Checklist & smoke tests.
  • Treating CFML as tag-only Risk: Monoliths. Fix: Prefer CFScript, MVC, and DI for testability.
  • Ignoring monitoring/JVM tuning Risk: Slowdowns without insight. Fix: Add APM early; set baselines.
  • Hard-coding secrets Risk: Leaks & migrations pain. Fix: Env vars & secret managers.
  • Overusing session scope Risk: Memory bloat. Fix: Stateless APIs, short-lived tokens, distributed caches.
  • Deferring upgrades Risk: Security & EOL issues. Fix: Annual Upgrade plan; test containers early.
  • Underestimating PDFs/spreadsheets Risk: Timeouts/memory. Fix: Offload, pre-generate, optimize assets.
  • Weak Git/CI/CD Risk: Fragile releases. Fix: PRs, pipelines, tests for every merge.
