Node Properties and Styling

Rekhic provides purpose-built styling tools to ensure your architecture diagrams remain professional, high-contrast, and easy to parse during technical reviews.

1. Stroke and Fill Colors

Select any node to reveal the floating context toolbar:

• Fill Color: Choose from neutral architectural grays, soft pastels, or transparent fills.
• Stroke Color: Choose from distinct technical colors (e.g. blue for applications, amber for databases, purple for messaging queues, red for external APIs).
• Stroke Style:
  • Solid: Production services and active dependencies.
  • Dashed: Boundaries, subnets, VPCs, or asynchronous message paths.

2. Component Categorization

Architecture nodes support semantic categories that map directly to documentation:

• Application: Web frontends, mobile clients, SPAs, and client-side applications.
• Service / API: Microservices, REST APIs, GraphQL endpoints, background worker daemons.
• Database / Data Store: Relational databases, key-value stores, document stores, data lakes.
• Queue / Event Bus: Kafka brokers, RabbitMQ queues, Amazon SQS/SNS, Redis Pub/Sub.
• External System: Third-party APIs (Stripe, Twilio, Auth0, SendGrid).

Categorizing your components ensures that the Diagram to Documentation exporter groups elements accurately into markdown tables.

3. Technology Badges

Architecture nodes display technology icons selected from the built-in icon picker:

• Search by framework: Next.js, React, Spring Boot, FastAPI, Go, Node.js.
• Search by cloud provider: AWS Lambda, EC2, S3, RDS, CloudFront, Route 53.
• Search by database: PostgreSQL, MySQL, MongoDB, Redis, Cassandra.
