New Line Chart: WAU (Weekly Active Users) by Role

What type(s) of user does this feature affect?

• supervisors?
• admins?

Description

On the /health page, add a new line chart.
-WAU: count unique users by role (Volunteer, Supervisor, Admin) who logged in a given week on that month

Create a json endpoint for the chart data. Make sure the json contains the minimum amount of data for the chart. Make sure the endpoint is accessible to users who are logged out.

If chart creation fails, display an error to the user explaining why. Print a detailed version of the error in the console.

No testing required but prove your solution works.

Questions? Join Slack!

We highly recommend that you join us in slack #casa channel to ask questions quickly. And discord for office hours (currently Tuesday 5-7pm Pacific), stakeholder news, and upcoming new issues.

Read app/controllers/health_controller.rb and app/javascript/src/display_app_metric.js, then review issue #5530 and the Chart.js line-chart example. Verify the health-page data endpoint is usable while logged out, supplies weekly unique-user counts by role, and that chart failures show a user-facing message with details in the console. Confirm the working chart on the QA site.
