How to use Vuex in UniApp
Introduction
Vuex is a state management tool that allows you to centrally manage applications in Vue.js applications Program state and logic. As a cross-platform development framework, UniApp also supports the use of Vuex.
Install Vuex
First, use the following command to install Vuex dependencies:
npm install vuex --save
or
yarn add vuex
Create Vuex storage
Next, create a Vuex store that will contain the application's state and logic.
// store/index.js import Vuex from 'vuex' import Vue from 'vue' Vue.use(Vuex) const store = new Vuex.Store({ state: { count: 0 }, mutations: { increment (state) { state.count++ } }, actions: { incrementAsync ({ commit }) { setTimeout(() => { commit('increment') }, 1000) } }, getters: { getCount (state) { return state.count } } }) export default store
Using Vuex in a component
To access the Vuex store from a component, you can use this.$store
.
// App.vue <template> <div>{{ this.$store.state.count }}</div> <button @click="increment">Increment</button> <button @click="incrementAsync">Increment Async</button> </template> <script> import { mapActions } from 'vuex' export default { methods: { ...mapActions([ 'increment', 'incrementAsync' ]) } } </script>
Modular Vuex Store
For large applications, it is useful to split the Vuex store into multiple modules. Each module can manage its own state and logic.
// store/index.js import Vuex from 'vuex' import Vue from 'vue' import counter from './modules/counter' Vue.use(Vuex) const store = new Vuex.Store({ modules: { counter } }) export default store
// store/modules/counter.js export default { state: { count: 0 }, mutations: { increment (state) { state.count++ } }, actions: { incrementAsync ({ commit }) { setTimeout(() => { commit('increment') }, 1000) } }, getters: { getCount (state) { return state.count } } }
Tip
- Create Vuex storage when the application starts.
- Access the Vuex store from within the component using
this.$store
. - Bind Vuex actions and states into components by using mapping helpers such as
mapActions
andmapState
. - Vuex storage can be split into multiple modules as needed.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
