@edemaine/meteor-tracker

Meteor Tracker is a dependency tracking system from Meteor. Together with Meteor ReactiveVar, it makes it easy to rerun code when dependencies change.

This NPM package @edemaine/meteor-tracker offers a drop-in replacement for the meteor/tracker and meteor/reactive-var modules available in Meteor with the tracker and reactive-var packages, so that it can be used in other JavaScript projects, in particular for testing NPM packages that are intended for Meteor but testing from outside Meteor (e.g. via Jest).

The code consists of a few one-line changes to Meteor's source code (see CHANGE FOR NPM in the code), to make the Node module imports and exports match those in Meteor.

For a more complete set of Meteor ports, check out Blast on NPM.

Versions

The intent is to track the latest version of Meteor Tracker. If the latter changes, please open an issue to update this package.
