3. Incremental Adoptability
more Library-ish than Framework-esque
Vue Resource !
Vue Router !
Vuex
AJAXy GET/POSTs !
Single Page App URLs !
State Machine
4. Plays well with Others
<script lang="coffee"> module.exports = props: ['options'] methods: sort: (event) -> @$emit ‘change' event.target.value </script> !<style lang="sass"> @import "components"; div.dashboard-sort { margin-right: 1.45em; margin-bottom: 1em; @include select(1.25em); } </style>
5. Goes with the Grain
One of Ruby’s friends really makes her crazy. When they try to wrap Christmas presents together Ruby wants to be creative and have many different ways of using the wrapping paper. !- No, says Django.
There is one - and only one - obvious way to wrap a present.
Gotchas
google vue events !
use of this. !
array manipulations
</thead> <transition-group name="board-list" tag="tbody"> <board-game v-for="game in sorted" :type="game.type" :name="game.name" :key="game.id"> <board-delete :id="game.id" @delete="handleDelete"></board-delete> </board-game> </transition-group> </table>
BoardLibrary.vue
methods: { handleAdd: function (game) { game.id = idGenerator++ this.games.push(game) },
<style> .board-list-move { transition: transform 1s; } .board-list-enter-active, .board-list-leave-active { transition: all 0.5s; } .board-list-enter, .board-list-leave-active { opacity: 0; } .board-list-enter { transform: translateX(960px); } .board-list-leave-active { transform: translateX(-960px); } :
