  1 | == How to Visualize Jigsaw Module Graph
  2 | 
  3 | This is a demo to show how can we visualize Jigsaw module graph in a Java application.
  4 | 
  5 | Module API can list Jigsaw modules and its dependents like below.
  6 | 
  7 | [source,java]
  8 | ----
  9 | Set<Module> modules = ModuleLayer.boot().modules();
 10 | Set<Requires> requires = module.getDescriptor().requires();
 11 | ----
 12 | 
 13 | With these two simple command, we can access to module relation graph in a running application.
 14 | 
 15 | To visualize module relations, http://visjs.org/[visjs] can be used. It is easy to create network graphs with visjs. Take a look at the following code snippet.
 16 | 
 17 | [source,javascript]
 18 | ----
 19 | // create an array with nodes
 20 |   var nodes = new vis.DataSet([
 21 |     {id: 'java.base', label: 'java.base'},
 22 |     {id: 'java.logging', label: 'java.logging'},
 23 |     {id: 'java.sql', label: 'java.sql'}
 24 |   ]);
 25 | 
 26 |   // create an array with edges
 27 |   var edges = new vis.DataSet([
 28 |     {from: 'java.sql', to: 'java.base'},
 29 |     {from: 'java.sql', to: 'java.logging'},
 30 |     {from: 'java.logging', to: 'java.base'}
 31 |   ]);
 32 | 
 33 |   // create a network
 34 |   var container = document.getElementById('mynetwork');
 35 |   var data = {
 36 |     nodes: nodes,
 37 |     edges: edges
 38 |   };
 39 |   var options = {};
 40 |   var network = new vis.Network(container, data, options);
 41 | ----
 42 | 
 43 | The view should be like below.
 44 | 
 45 | image::basic-graph.png[]
 46 | 
 47 | Let's create whole alive module graph visualizer.
 48 | 
 49 | [source,java]
 50 | .Node.java
 51 | ----
 52 | public class Node {
 53 |     private String id;
 54 |     private String label;
 55 | 
 56 |     // getters, setters, constructor
 57 | }
 58 | ----
 59 | 
 60 | Node.java represents Node data. Each module name will have one node.
 61 | 
 62 | [source,java]
 63 | .Edge.java
 64 | ----
 65 | public class Edge {
 66 |     private String from;
 67 |     private String to;
 68 | 
 69 |     // getters, setters, constructors
 70 | }
 71 | ----
 72 | 
 73 | Edge.java represents edge between two node.
 74 | 
 75 | [source,java]
 76 | .ModuleGraphController.java
 77 | ----
 78 | @RestController
 79 | public class ModuleGraphController {
 80 | 
 81 |     @GetMapping("/modules")
 82 |     public Map<String, HashSet<?>> moduleInfo() {
 83 |         var nodes = new HashSet<Node>(); // <1>
 84 |         var edges = new HashSet<Edge>(); // <2>
 85 |         fillNodeAndEdges(nodes, edges); // <3>
 86 |         return Map.of("nodes", nodes, "edges", edges); // <4>
 87 |     }
 88 | 
 89 |     private void fillNodeAndEdges(HashSet<Node> nodes, HashSet<Edge> edges) {
 90 |         Set<Module> modules = ModuleLayer.boot().modules(); // <5>
 91 |         for (Module module : modules) {
 92 |             String moduleName = module.getName();
 93 | 
 94 |             if (moduleNotContain(moduleName, "jdk")) { // <6>
 95 |                 nodes.add(new Node(moduleName));
 96 |             }
 97 | 
 98 |             Set<Requires> requires = module.getDescriptor().requires(); <7>
 99 |             for (Requires require : requires) {
100 |                 edges.add(new Edge(moduleName, require.name())); <8>
101 |             }
102 |         }
103 |     }
104 | 
105 |     private boolean moduleNotContain(String moduleName, String text) {
106 |         return !moduleName.startsWith(text);
107 |     }
108 | }
109 | ----
110 | <1> Create node set
111 | <2> Create edge set
112 | <3> Fill node and edge sets
113 | <4> Return edge and node sets in a map
114 | <5> Access module list
115 | <6> Skip jdk internal modules for clarity
116 | <7> Access module's dependents
117 | <8> Fill edge between module and dependent
118 | 
119 | That's all!
120 | 
121 | Result
