The various parsers of the ccsh supply a large variety of different metrics out of the box. In case these not match your need, there are two general ways to add new metrics to CodeCharta.

The more ‘expensive’ way is to add a new importer, generate a new .cc.json and then merge that with your existing .cc.json. If you are interested in this, please get in contact with us by creating a new issue in GitHub.

However, there is an easier way if your metric data is available in CSV form because we have an importer for such data. All the importer needs is the file name (including path to it to depict the folder structure) and the different metrics. This makes it possible to display various metrics, independently of how they were generated.

Custom Metric CSV ImportPermalink

Suppose that you had a file newmetrics.csv with the following contents:

name,Metric1,Metric2
File.js,4,500
service/Service1.ts,40,20

You can transform that file into a .cc.json with our CSV Importer via command-line:

ccsh csvimport newmetrics.csv -o newmetrics.cc.json

This will result in a new file called newmetrics.cc.json which can be used as is or merged into existing standardmetrics.cc.json files. For example to merge this newmetrics.cc.json with a file called standardmetrics.cc.json, execute:

ccsh merge newmetrics.cc.json standardmetrics.cc.json -o mergedmetrics.cc.json

Both the newmetrics.cc.json and the standardmetrics.cc.json files are valid cc.json files that can be used in our visualisation.

If you are interested in how a cc.json file for custom metrics looks like, here is what the newmetrics.cc.json looks like:

{
  "projectName": "myproject",
  "apiVersion": "1.1",
  "nodes": [
    {
      "name": "root",
      "type": "Folder",
      "attributes": {},
      "link": "",
      "children": [
        {
          "name": "File.js",
          "type": "File",
          "attributes": { "Metric1": 4.0, "Metric2": 500.0 },
          "link": "",
          "children": []
        },
        {
          "name": "service",
          "type": "Folder",
          "attributes": {},
          "link": "",
          "children": [
            {
              "name": "Service1.ts",
              "type": "File",
              "attributes": { "Metric1": 40.0, "Metric2": 20.0 },
              "link": "",
              "children": []
            }
          ]
        }
      ]
    }
  ]
}
