Bulk delete activities in Garmin Connect

fu-garmin-bulk-delete.js

function foo() {
  console.log("foo - start")
  $("button.search-button").click()
  setTimeout(function() {
    var li = $(".list-item")[0]
    var delButton = $(li).find("button.js-activity-delete")
    var confirmDelButton = $(li).find("button.delete-yes")

    console.log(delButton, confirmDelButton)

    $(delButton).click()

    setTimeout(function() {
      $(confirmDelButton).click()
      console.log("foo - end")
    }, 100)
  }, 2000)
}

setInterval(foo, 3000)

I wrote my own script for this recently. Go to https://connect.garmin.com/modern/courses then paste this into your console:

(() => {
  // Every 1 second, click the little trash can icon next to a course
  setInterval(() => {
    document.querySelector("button[aria-label='Delete']").click();

    // Wait 500ms for the modal to open, then click the delete button
    setTimeout(() => {
      // This delete button doesn't have a good class name, so find all the
      // buttons, then find one with the text "Delete"
      const buttons = document.querySelectorAll("button");
      const deleteButton = Array.from(buttons).find((button) =>
        button.textContent.includes("Delete"),
      );
      deleteButton.click();
    }, 500);
  }, 1000);
})();
