Awesome
Pssst... I'm not working with Vue anymore. This plugin is old and bad. Here is a better alternative: https://github.com/MDSLKTR/pouch-vue. However, if for whatever reason you find yourself looking at this, please re-evaluate your life choices and look at Svelte.
vue-pouch
Reactive Vue bindings for PouchDB using pouchdb-live-find.
Examples
Todo App with real-time 4-way data syncing: DOM <-> Vue <-> IndexedDB <-> CouchDB
Try this example here: https://buhrmi.github.io/vue-pouch/
<template>
<div class="todos">
<input v-model="message" placeholder="New Todo">
<button @click="$pouch.post('todos', {message: message});message=''">Save Todo</button>
<div v-for="todo in todos">
<input v-model="todo.message" @change="$pouch.put('todos', todo)">
<button @click="$pouch.remove('todos', todo)">Remove</button>
</div>
</div>
</template>
<script>
export default {
// VuePouch adds a `pouch` config option to all components.
pouch: {
// The simplest usage. queries all documents from the "todos" pouch database and assigns them to the "todos" vue property.
todos: {/*empty selector*/}
},
created: function() {
// Send all documents to the remote database, and stream changes in real-time
this.$pouch.sync('todos', 'http://localhost:5984/todos');
}
}
</script>
Reactive & Live Selectors (Mango Queries)
<template>
Show people that are <input v-model="age"> years old.
<div v-for="person in people">
{{ person.name }}
</div>
</template>
<script>
export default {
data () {
return {
resultsPerPage: 25,
currentPage: 1
}
},
// Use the pouch property to configure the component to (reactively) read data from pouchdb.
pouch: {
// The function returns a Mango-like selector that is run against the `people` database.
// The result of the query is assigned to the `people` property.
people: function() {
if (!this.age) return;
return {age: this.age, type: "person"}
},
// You can also specify the database dynamically (local or remote), as well as limits, skip and sort order:
peopleInOtherDatabase: function() {
return {
database: this.selectedDatabase, // you can pass a database string or a pouchdb instance
selector: {type: "person"},
sort: [{name: "asc"}],
limit: this.resultsPerPage,
skip: this.resultsPerPage * (this.currentPage - 1)
}
}
}
})
</script>
Single documents
If you only want to sync a single document that matches a selector, use first: true
:
module.exports = {
// ...
pouch: {
projectDetails: function() {
return {
database: 'mydatabase',
selector: {_id: this.selectedProjectId},
first: true
}
}
}
// ...
}
Installation
Install via npm:
npm install --save vue-pouch
The only requirement is that pouchdb-live-find
is installed:
import PouchDB from 'pouchdb-browser'
PouchDB.plugin(require('pouchdb-find'));
PouchDB.plugin(require('pouchdb-live-find'));
If you want to use remote databases (CouchDB, Cloudant, etc.), you should also install the authentication plugin:
PouchDB.plugin(require('pouchdb-authentication'));
Then, plug VuePouch into Vue:
Vue.use(require('vue-pouch'), {
pouch: PouchDB, // optional if `PouchDB` is available on the global object
defaultDB: // the database to use if none is specified in the pouch setting of the vue component
})
API
$pouch
$pouch
is made available on all vue instances and has some helper functions. Note that this API is not stable and will probably change.
Methods
$pouch.sync(localDatabase, remoteDatabase)
: Basically the same as PouchDB.sync(local, remote, {live: true, retry: true}). Also, if the browser has an active session cookie, it will fetch session data (username, etc) from the remote server. BONUS: If your remote database runs CouchDB 2.0 or higher, you can also specify a Mango Selector that is used to filter documents coming from the remote server.
For example
$pouch.sync('complaints', 'https:/42.233.1.44/complaints', {
filter:'_selector',
selector: {
type: 'complaint',
assignee: this.session.name
}
})
$pouch.push(localDatabase, remoteDatabase)
: Like localdb.replicate.to(remotedb, {live: true, retry: true}). Also, if the browser has an active session cookie, it will fetch session data (username, etc) from the remote server.$pouch.put/post/remove/get(database, ...)
: Same as db.put(...)$pouch.createUser(name, password)
: Create a user in the remote database and also start a new session.$pouch.useAuth(name, password)
: Set credentials to use to start a session with the remote server.$pouch.resetAuth()
: Forgets the credentials, session data and session cookie.
Reactive Properties
$pouch.loading
: Contains an object with synced database names as the keys. The value of each key istrue
while the initial loading happens. This API is a little bit unreliable at the moment.$pouch.hasAuth
:true
, if VuePouch has credentials$pouch.authError
: Contains the authentication error, if one occured (eg. when calling useAuth, createUser, etc).$pouch.session
: Contains information about the current session with the remote database (eg. user name, roles, etc.)$pouch.errors
: A json object containing errors that occured on databases. The object key is the name of the database, the value is the error.
Non-Reactive Properties
vm.$databases
: the pouchdb instances. shared across all components.
