A Vue plugin to sync router queries and hash with state.

This plugin requires that your project use Vue Router in history mode

Why?

Allow users to deep link (bookmark) to state outside of normal routing such as:

• filtered lists
• searched lists
• modal states
• tabs
• etc.

Install

yarn add -D vue-url-state-sync
# or
npm i -D vue-url-state-sync

import Vue from 'vue';
import VueRouter from 'vue-router';
import VueUrlStateSync from 'vue-url-state-sync';

Vue.use(VueRouter);
Vue.use(VueUrlStateSync);

const router = new Router({
  mode: 'history', // must be in history mode for hashes to work!
  routes: [...]
});

const app = new Vue({
  router
}).$mount('#app')

Examples

Basic sync

<template>
  <input v-model="term" type="text" placeholder="Search term" />
</template>

<script>
  export default {
    name: 'Users',

    data() {
      return {
        showModal: false,
        searchTerm: 'foobar'
      };
    },

    beforeMount() {
      this.$vuss.h.sync('showModal');
      this.$vuss.q.sync('searchTerm');

      /**
       * Resulting URL
       * ?search_term=foobar#show-modal
       */
    }
  };
</script>

Vuex mapState

import { mapState } = 'vuex';

export default {
  name: 'Users',

  computed: {
    ...mapState('users', ['showModal'])
  },

  beforeMount() {
    // define a callback for when the hash changes
    this.$vuss.h.sync('showModal', 'showAddUserModal', (newVal) => {
      this.$store.commit('users/setShowModal', newVal);
    });
  }
};

Vuex computed with setter

export default {
  name: 'Users',

  computed: {
    showModal: {
      get() {
        return this.$store.state.users.showModal;
      },

      set(newVal) {
        this.$store.commit('users/setShowModal', newVal);
      }
    }
  },

  beforeMount() {
    this.$vuss.h.sync('showModal', 'showAddUserModal');
  }
};

Nested State

export default {
  name: 'Users',

  data() {
    return {
      list: {
        filters: {
          animal: 'dog',
          color: 'red',
          gender: 'male'
        }
      }
    };
  },

  beforeMount() {
    this.$vuss.q.sync('list.filters');
    /**
     * Resulting URL
     * ?list_filters=%7B"animal"%3A"dog","color"%3A"red","gender"%3A"male"%7D
     */

    this.$vuss.q.sync('list.filters', 'filters');
    /**
     * Resulting URL
     * ?filters=%7B"animal"%3A"dog","color"%3A"red","gender"%3A"male"%7D
     */
  }
};

Hashes vs Queries

Hashes

Hashes is intended to be used for simple boolean state, such as whether or not to show a modal. It is always converted to kebab-case.

export default {
  // data
  data() {
    return {
      modal: true
    };
  },

  // sync
  beforeMount() {
    // you can define both the state key and the hash value if you wish
    this.$vuss.h.sync('modal', 'showModal');

    // optional - define a callback for when the hash changes
    this.$vuss.h.sync('modal', 'showModal', newVal => {
      this.modal = newVal;
    });
  }
};

// result
('https://mysite.com#show-modal');

Queries

Queries is intended for data such as search terms, filters, current tab, etc. It is stringified on write, and parsed on read. Keys are always converted to snake_case.

export default {
  // data
  data() {
    return {
      filters: {
        animal: 'dog',
        color: 'red',
        gender: 'male'
      }
    };
  },

  // sync
  beforeMount() {
    // you can define both the state key and the query key if you wish
    this.$vuss.q.sync('filters', 'f');

    // optional - define a callback for when the query changes
    this.$vuss.h.sync('filters', 'f', newVal => {
      this.filters = { ...newVal };
    });
  }
};

// result
('https://mysite.com?f=%7B"animal"%3A"dog","color"%3A"red","gender"%3A"male"%7D');

Global Mixins

Two global mixins are installed by this plugin - one for syncing hash and one for syncing query queries.

Computed

vm.$hash

Provides hash

• Returns {string}

vm.$hash = 'show-modal'

vm.$query

Provides query

• Returns {object}

{
  term: 'foobar'
}

Methods

vm.$vuss.h.clear()

Clears hash

• Returns {void}

---

vm.$vuss.h.set(hash, replaceHistory)

Sets hash

• Arguments
  • {string} hash
  • {boolean} [replaceHistory=false] -- if true, a new history entry will not be added to the navigation stack
• Returns {void}

---

vm.$vuss.h.sync(state, hash, onHashChange)

Syncs the hash with specific component state.

When first called, it will sync the current hash to the state OR state to hash, in that order. It then sets up two watchers -- one for hash changes and one for state changes.

• Arguments
  • {string} state
  • {string} [hash] -- if not passed, is set to the value of state
  • {function} [onHashChange]
    • Called when Vue Router hash change detected
    • Arguments
      • {*} newVal
• Returns {void}

---

vm.$vuss.q.clear()

Clears query

• Returns {void}

---

vm.$vuss.q.exists(key)

Provides if query key exists

• Arguments
  • {string} key
• Returns {boolean}

---

vm.$vuss.q.push(hash)

Updates query query object.

• Arguments
  • {object} query
  • {function} [next=() => {}]
  • {boolean} [replaceHistory=false] -- if true, a new history entry will not be added to the navigation stack
• Returns {void}

---

vm.$vuss.q.remove(key)

Removes query value by key

• Arguments
  • {object} query
• Returns {void}

---

vm.$vuss.q.set(key, value, replaceHistory)

Sets query value by key

• Arguments
  • {string} key
  • {*} value
  • {boolean} [replaceHistory=false] -- if true, a new history entry will not be added to the navigation stack
• Returns {void}

---

vm.$vuss.q.sync(state, key, onQueryChange)

Syncs a query key with specific component state.

When first called, it will sync the current query to the state OR state to query, in that order. It then sets up two watchers -- one for query changes and one for state changes.

• Arguments
  • {string} state
  • {string} [key] -- if not passed, is set to the value of state
  • {function} [onQueryChange]
    • Called when Vue Router query change detected
    • Arguments
      • {*} newVal
• Returns {void}
