Vite Vue

Vue.js mixin for http operations and state management

Note: for now this app is old school style: ES5 with classic script load tags. The benefit is simplicity with zero cognitive load neither tooling requirements. It is usable with a classic javascript knowledge and basic Vue.js notions. That said some other flavours might come up later, like ES6 or Typescript. Anyway the classic old school approach and mindset will be supported.

Install

Import the libs in html header

<script type="text/javascript" src="/static/js/vue.min.js"></script>
<script type="text/javascript" src="/static/js/vuex.js"></script>
<script type="text/javascript" src="/static/js/page.js"></script>
<script type="text/javascript" src="/static/js/axios.min.js"></script>
<script type="text/javascript" src="/static/vv/vv.js"></script>
<script type="text/javascript" src="/static/vv/vvstore.js"></script>

The file vv.js is the mixin, vvstore.js is the store for state management

Usage

Fetch json data and use it:

const app = new Vue({
el: '#app',
mixins: [vvMixin],
data () {
   return {
      content: "",
   }
},
methods: {
   load: function() {
      function action(data) {
         app.content = data.something;
      };
      function error(err) { 
         console.log("ERROR", err);
      };
      // process network operation
      var url = 'http://localhost:8080/some_endpoint';
      this.loadData(url, action, error);
      // update state
      this.activate(["content"]);
   },
 },
});

API

Network operations

loadData(url, action, error): load data from an url and process an action on it

postForm(url, data, action, error, token): post a form and perform an action on response. The token is for csrf protection: provide it from your backend

State management

activate(elements, replace): set some elements active. The elements parameter must be an array. The replace parameter is optional: if set to true the active items will be replaced by the elements, otherwise the elements will be added to the active set of elements.

deactivate(elements): unset some element active

isActive(element): returns true or false

Utilities

flush(preserve): reset all active elements values depending on their type: an array will be set [], a string to "", a boolean to false and so on. Optionaly pass an element if you want not to reset it.

serializeForm(form): pass a dom form element and receive the serialized json based on the name attribute of the form elements.

postForm(url, data, action, error, token): data is your json serialized form data. Action and error are functions. The token is optional: if not provided the function will look for a global csrftoken variable and use it.

Shortcuts

get(nodeid) : shortcut for document.getElementById

str(json): prettify json for printing

query(q): urlencode a graphql query and returns /graphql?query=+ endcoded query
