rxjs-report-usage

The script within this package collects anonymous API usage statistics and reports them to the RxJS core team.

When run inside a project, the script locates all JavaScript and TypeScript files - except for those in the node_modules directory - and parses them with Babel. The parsed code is searched for import statements and require calls that consume rxjs and a usage count is recorded for each consumed RxJS API.

The script also locates any rxjs and typescript packages within node_modules and reports their versions. The versions of other packages are not included in the report.

The anonymous statistics that are collected look like this:

{
  "apis": {
    "rxjs": {
      "concat": 1,
      "merge": 1,
      "of": 4
    },
    "rxjs/operators": {
      "concatMap": 1,
      "mergeMap": 1
    },
  },
  "packageVersions": {
    "rxjs": ["6.5.5"],
    "typescript": ["3.9.5"]
  },
  "schemaVersion": 1,
  "timestamp": 1592659729551
}

Once the script has collected the usage statistics, the payload is shown and the developer is prompted to confirm the sending of the payload to the core team. The script sends no information without the developer's consent.
