nuxt-merge-asyncdata

0.1.1 • Public • Published

Util to merge asyncData methods on route pages in nuxt framework.

Install

npm i nuxt-merge-asyncdata -save

Usage

import nmerge from "nuxt-merge-asyncdata"
 
export default nmerge({...}) // asynchronous
export default nmerge.sync({...})
export default nmerge.manual({...})
export default nmerge.controlled({...})
 

API

nmerge({...})

Default method will collect all asyncData methods and run them in parallel (asynchronous). Results will be merged together with respect to hierarchy.

import nmerge from "nuxt-merge-asyncdata"
 
let base = {
  asyncData: async (ctx) => {
    console.log('asyncData in base: start')
    await new Promise(res => setTimeout(() => res(), 1000)) // some delay
    console.log('asyncData in base: end')
    return { value: 1 }
  }
}
 
export default nmerge({
  mixins: [base],
  asyncData: async (ctx) => {
    console.log('asyncData in component')
    return { value: 2 }
  },
  created: function () {
    console.log('value is', this.value)
  }
})

Result

> asyncData in base: start
> asyncData in component
> asyncData in base: end
> value is 2

nmerge.sync({...})

sync method differs in a way that it will run asyncData methods synchronously, it will also continuously merge results and pass them to next method in context field asyncDataResult

import nmerge from "nuxt-merge-asyncdata"
 
let base = {
  asyncData: async (ctx) => {
    console.log('asyncData in base: start')
    await new Promise(res => setTimeout(() => res(), 1000)) // some delay
    console.log('asyncData in base: end')
    return { value: 1 }
  }
}
 
export default nmerge.sync({
  mixins: [base],
  asyncData: async ({ asyncDataResult }) => {
    console.log('asyncData in component, base result is:', asyncDataResult)
    return { value: 2 }
  },
  created: function () {
    console.log('value is', this.value)
  }
})

Result

> asyncData in base: start
> asyncData in base: end
> asyncData in component, base result is: { value: 1 }
> value is 2

nmerge.manual({...}) nmerge.controlled({...})

These methods will just flatten out mixins hierarchy removing duplicates and filter out mixins without asyncData methods, resulted array will be passed to component asyncData method in mixins field.

Difference between manual and controlled is that if asyncData is not present on passed component then controlled will assume that invocation of base asyncData methods is desired and will fallback on default (asynchronous) method whether manual will do nothing.

import nmerge from "nuxt-merge-asyncdata"
 
let core = {
  name: 'core',
  asyncData: async (ctx) => { ... }
}
 
let base = {
  name: 'base',
  mixins: [core],
  asyncData: async (ctx) => { ... }
}
 
let comp2 = {
  name: 'comp2',
  mixins: [core],
  asyncData: async (ctx) => { ... }
}
 
export default nmerge.controlled({
  mixins: [base, comp2],
  asyncData: async ({mixins}) => {
    // mixins[0] === core
    // mixins[1] === base
    // mixins[2] === comp2
    return { value: 2 }
  }
})
