ActionView helper methods for injecting Vue.js components into your Rails views

Rails Vue Helpers

This small helper gem allows you to add Vue components to your Rails views with a clean syntax.

Instead of writing

<some-component v-on:click='doThis' v-bind:vueParam="<%= @some_instance.to_json %>" />

you can write

<%= vue_component('someComponent', events: { click: 'doThis'}, binded: { vue_param: @some_instance}) %>

This gem conveniently calls to_json on objects, as well as handles cases where parameters include single or double quotes, without screwing up HTML rendering.

All you need to do this wrap everything in a Vue initialized container, and you're good to go.

Installation

gem 'rails_vue_helpers'

Usage

vue_component('componentName', **args, &block)

All arguments, except special keys: binded:, events:, raw: are translated in regular camelCased Vue props

Events

<%= vue_component('someComponent', events: { click: 'doThis'} ) %>

will result in

<some-component v-on:click='doThis'></some-component>

Binded parameters

<%= vue_component('someComponent', binded: { some_array: ['a', 'b'], some_boolean: true } ) %>

will result in

<some-component v-bind:someArray="['a', 'b']", v-bind:someBoolean="true"></some-component>

Directives or custom attributes

<%= vue_component('someComponent', raw: 'v-something v-something-else') %>

will result in

<some-component v-something v-something-else></some-component>

Wrapper

<%= vue_component('someWrapperComponent') do %>
  <div>Everything else you need in rails view</div>
  <%= vue_component('someInnerComponent') %>
<% end %>

will result in

<some-wrapper-component>
  <div>Everything else you need in rails view</div>
  <some-inner-component></some-inner-component>
</some-component>
