I base on Meteor + Vue + Vue Tracker

  meteor: {
    $subscribe: {
      ['app.company']: [],
    company() {
      const val = Company.findOne()
      return val
    },
  },
  watch: {
    company: {
       handler(val) {
         console.log(val)
         this.$store.commit('app/updateCompany', val)
       },
       immediate: true,
    },

The watcher don’t work when company changed.
