Can I use external database in my app

can I use external database in my app, if it is true, how can i do this.

We don’t have any official guides on this. You’ll have to experiment with that.

What kind of app are you building?

thanks,I want to build a app for internal using, there is a SQL server being use.

another question,next is the code in src/main.js,where an i find the manual for t,n,h,thank you:

Vue.mixin({ methods: { t, n } })

export default new Vue({
el: '#content',
render: h => h(App),
