@empirica/core@1.9.2

@empirica/core@1.9.1

• fe46f00: Export vector attributes to CSV as arrays.

@empirica/core@1.9.0

Minor Changes

• cd48506: empirica export could fail with a "Premature close" error (#474). This seems
  to be originating from a bug in the node-fetch package, which is used to
  polyfill fetch in Node.js. This upgrades Node.js to v20+, which includes
  native fetch support. We still have the cross-fetch polyfill for projects
  that have not updated to Node.js v20+ yet. Export uses a vendored project which
  has been updated to use the latest Node.js version, so it does not require the
  entire experiment to be updated for it to use Node.js v20+.

  See the following issues on node-fetch for more details:
  node-fetch/node-fetch#1767
  node-fetch/node-fetch#1576

Patch Changes

• b32b95a: Scoped objects should never be missing under EmpiricaContext. Some have reported
  player.stage or player.round being undefined, for example. This fix also
  more thoroughly checks that all expected objects (not only scoped objects) are
  always present.

@empirica/core@1.8.12

Patch Changes

• c20ca73: Fix setting attributes with the same mutated object as the current one.

  For example, before this patch, the value would not be saved, since we are
  reusing the same object, which we've only mutated in place:

  const value = player.get("myobject");
  value["mykey"] = "myvalue";
  player.set("myobject", value);

• d1816ad: Ensure usePlayers never returns undefined (expect in unmanaged games).

@empirica/core@1.8.11

Patch Changes

• a5ecdbd: Avoid re-setting a key to the same value from the client side. For example:

  scope.set("key", "value");
  scope.set("key", "value"); // no-op

  This is not only for sets in the same tick as shown here, but also across ticks.

• a5ecdbd: Improve various concurrency issues.

• a5ecdbd: When has no steps, only set the doneKey once.

@empirica/core@1.8.10

Patch Changes

• 98d72e9: Handle errors in step state transition requests.

@empirica/core@1.8.8

Patch Changes

• 44c9486: Upgrade tajriba.js to version 1.5.0.
