February Rollup

Functional Core, Imperative Shell in Svelte

reddit.com
Author: kirkegaarr
Date: Jan 8, 2025

• Functional Core:

  • Encapsulated in a “lib” package.
  • Contains only pure functions and data models (e.g., CashIndexViewModel, PrimalViewModel).
  • Has no dependencies, ensuring testability and reusability.

• Imperative Shell:

  • UI components (.svelte files) handle side effects, events, and imperative interactions.
  • Example: Cash.svelte

    $: model = CashIndexViewModel.from(cash);
    $: ({ stats, selected } = model);

  • Binds UI elements to the functional core via reactive statements ($: model = ...).

• Patterns in the Shell:

  • Event-driven updates: UI components modify state by calling methods on the functional core.

    <ObservationChart on:selectDate={event => model.selectDate(event.detail)} />

  • Separation of concerns: API calls in separate ./app/api modules.

    const purchases = (start: Date, end: Date): Promise<Purchase[]> =>
        fetch(`/api/purchases?start=${formatDate(start)}&end=${formatDate(end)}`)
        .then(response => response.json())
        .then(Purchase.parse);

  • ViewModels as Adapters: UI binds to ViewModel.from(data), ensuring separation of logic.

• Key Takeaways:

  • Testability: Functional core has 100% unit test coverage.
  • Flexibility: UI can change without modifying core logic.
  • Scalability: Pure functions allow easy refactoring and reusability.

Best Practices for Integrating DevOps Files with Application File Structure

reddit.com
Author: Various (r/devops community)
Date: Dec 4, 2023

• Keep Dockerfiles Close to the Code: Many suggest placing Dockerfiles within each app’s repo for easier development and maintenance.
• Separate Infrastructure Repos:
  • Terraform² and IaC³ configs often belong in a separate repo due to different lifecycles.
  • Some prefer an IaC monorepo for Helm⁴, Kustomize⁵, and Kubernetes manifests.
• K8s Manifests Placement:
  • Some store them in an ArgoCD⁶ repo for versioning and automated deployments.
  • Others keep them alongside app code, especially when devs interact with them.
• CI/CD & DevOps Folder:
  • .github or .circleci at the root for workflows.
  • A dedicated devops/ folder may centralize Terraform², K8s manifests⁵, and Dockerfiles⁷, but risks isolation from dev teams.
• Golden Paths & Standardization:
  • A single repo approach makes onboarding, deployment, and lifecycle management easier.
  • Some advocate fully rendered, versioned K8s manifests in a repo for automated deployment via ArgoCD⁶.

• DNS-01 Benefits:

  • Works without exposing servers publicly.
  • Supports wildcard certificates (e.g., *.homelab.xyz).

• Requirements:

  • DuckDNS⁹ (or any DNS provider supporting Let’s Encrypt DNS-01).
  • Reverse Proxy: Nginx Proxy Manager¹⁰ (or alternatives: Traefik¹¹, Caddy¹², SWAG¹³).
  • Docker installed via APT.

• Setup Steps:

  1. Install Docker & docker-compose.
  2. Deploy Nginx Proxy Manager¹⁰, Jellyfin, Home Assistant, Nextcloud using docker-compose.yml.
  3. Register a DuckDNS⁹ domain, point it to the reverse proxy’s local IP.
  4. Configure Let’s Encrypt SSL⁸ in Nginx Proxy Manager¹⁰:
     • Use a DNS Challenge with DuckDNS API token.
     • Set wildcard certificate (*.yourdomain.duckdns.org).
  5. Add proxy hosts in Nginx Proxy Manager¹⁰.
  6. Enable Force SSL and HTTP/2 for secure connections.

• Extras:

  • Nginx Proxy Manager¹⁰ supports custom Nginx configs, user ACLs, audit logs, HTTP streams, redirects.

FAST and Team Topologies: Organizing for Agility

jamesshore.com
Author: James Shore
Date: January 10, 2025

• FAST (Fluid Scaling Technology)¹⁹ as an Alternative to Team Topologies²⁰:

  • Traditional Team Topologies create rigid team structures, leading to silos, cross-team friction, and difficulty reallocating resources.
  • FAST is a self-organizing model, where teams dynamically reform every few days based on current business priorities.
  • Engineers self-select into teams that match their interests and business needs, ensuring fluid alignment with evolving priorities.

• How FAST Works:

  • Regular meetings (every 2-3 days) where engineers volunteer to lead teams and choose what to work on.
  • People self-select into teams based on what they want to work on and organizational needs.
  • Eliminates inter-team coordination issues by keeping all engineers within a single large “collective” per product.

• Benefits Over Team Topologies:

  • Eliminates silos: Engineers shift roles naturally instead of being locked into static teams.
  • Enhances agility: No need for disruptive reorgs when business priorities shift.
  • Reduces task switching: Specialists (e.g., UX, DevOps, security) stay embedded in the collective instead of being spread thin.
  • Encourages ownership and leadership: Engineers drive decisions instead of relying on top-down management.

• XP Practices Support Tactical Agility:

  • Extreme Programming (XP) ensures adaptability by focusing on test-driven development, evolutionary design, and fast feedback loops.
  • Helps maintain high internal quality, preventing technical debt from slowing product changes.

CI/CD, Release Process, and E2E Testing in Different Workplaces

reddit.com
Author: Various (Discussion Thread)
Date: January 25, 2025

OP’s Challenges & Proposed Changes

• Current flow: Feature branches → staging → main for production; hotfixes cherry-picked.
• Issues:
  • Manual QA slows releases, e2e tests might reduce this.
  • No test environment for hotfixes beyond local.
  • Unfinished features merged into dev, making production readiness uncertain.

Key Responses & Insights

• Full Automation Works Best (bobs-yer-unkl, serial_crusher)

  • No manual QA in 11+ years; rely on 100% automated acceptance tests.
  • Ephemeral environments³¹ spun up per branch, auto-torn down after merging.
  • 100% test coverage required before merging.
  • Deployment straight to production after automated tests pass.
  • Downside: Some teams struggle with maintaining test quality; hiring responsible devs is key.

• Feature Flags & E2E (Axum666)

  • Feature flags shouldn’t be controlled by tests—can cause unintended failures.
  • Instead, use flags to control tests, allowing devs to enable them selectively³².

• Alternative Testing & Release Strategies

  • Shadow Traffic Testing³¹ (CubicleHermit)
    • Some companies mirror production traffic to staging for real-world validation.
  • Pre-Release Stabilization (edgmnt_net)
    • Merge early but allow time for stabilization before final release.
  • Trunk-Based Development (Unsounded)
    • No branches; code flows to a non-prod environment for constant e2e & stress testing.
    • Feature flags used only for gradual rollouts, not for standard feature gating.

• Enterprise CI/CD Model (500+ Devs) (CubicleHermit)

  • BE monolith follows strict CI/CD with tiered deployments:
    1. Branch-level: Runs unit & limited e2e tests.
    2. Main merge: Re-runs all tests, detects semantic conflicts.
    3. Staging: Full e2e tests run 24/7.
    4. Preprod (dogfooding): Rollout follows a time-based soak.
    5. Prod: Deploys 4x/day with canary releases.

Takeaways

• More branches ≠ better process—smaller, frequent merges reduce overhead.
• Manual QA should be minimized, but e2e alone may not eliminate it.
• Ephemeral environments³¹ improve testing efficiency—ideal for greenfield projects.
• Feature flags require discipline—they aren’t a silver bullet³².
• Enterprise CI/CD uses staged rollouts & shadow testing³¹ for robustness.
