Props down, events up

In Vue.js, the parent-child ponent relationship can be summarized as props down, events up. The parent passes data down to the child via props, and the child sends messages to the parent via events.

In particular, if the state of a ponent needs to be controlled externally (by a parent or sibling), that state should be passed in as a prop from the parent. Events indicate to the parent that the state should be changed.

Your modal's state is controlled by events in itself and in a sibling ponent. So the state lives in the parent, and is passed to the modal as a prop. Clicking the modal Close button emits a (custom) hidemodal event; clicking the sibling ponent's ment icon emits a showmodal event. The parent handles those events by setting its showRepoModal data item accordingly.

Vue.ponent('repo-button', {
  template: '#repo-button',
  methods: {
    showRepo: function() {
      this.$emit('showmodal');
    }
  }
});

Vue.ponent('repo-modal', {
  template: "#repo-modal",
  props: ["show"],
  puted: {
    status() {
      return this.show ? 'block' : 'none'
    }
  },
  methods: {
    hideRepo() {
      this.$emit('hidemodal');
    }
  }
});

var repositionings = new Vue({
  el: "#repo-vue",
  data: {
    showRepoModal: false
  }
});
