tc

Visualizer

The composer generates various output formats to visualize or inspect the topology.

tc compose -f <format>

The following are some available formats

  1. json
  2. table
  3. tree
  4. digraph
  5. icepanel

Let’s try various formats in examples/patterns/rest-async-progress

tc compose -f tree

tc compose -f table
 entity   | name | target_entity | target_name
----------+------+---------------+-------------
 function | f1   | function      | f2
 function | f1   | channel       | c1
 function | f3   | channel       | c1
 function | f2   | function      | f3
 function | f2   | channel       | c1

We can also visualize the topology as dot SVG in a standalone HTML page by running tc visualize in the topology dir.
