Integraph

Create Architecture diagrams from your code.

Architecture

Install

npm install -g integraph

Usage

Map integrations adding @integraph comments in your source code:

class ECommerce {
    /**
     * @integraph
     * service: e-commerce
     * integrations:
     *   - service: Payment gateway
     *     edgeDirection: RL
     *     group: External APIs
     */
    processsPayment() {
        // ...
    }
}

Under your project root directory/repository, run the following command:

integraph

The generated diagram:

It will search for files containing @integraph comments and mapping all integrations, and as results it generates the following files under the directory .integraph:

• diagram.js

  • it contains the function getDiagram which returns the mermaid architeture diagram.

      group externalapis[External APIs]
  
      service ecommerce(server)[e_commerce]
      service paymentgateway(server)[Payment gateway] in externalapis
  
      ecommerce:R -[ecommerce__paymentgateway]- L:paymentgateway
  

• integrations.js

  • it contains the funciton getIntegrations which returns a json with all mappend integrations.

              "row":1,
              "column":4

                      "group":"External APIs"
                  }

          "sourceCode":"class ECommerce { ..."
      }
  ]

• arch.html

  • a html page containing the diagram and a few actions such as refresh, show diagram source, and show integrations json. Addtionally, it makes all edges clickable, adding the ability to open the souce file where the integration is defined.

  

• main.css

  • this is the css styles for the page arch.html

• main.js

  • this is the main js file which initialize mermaid library, render the diagram, etc.
