Vue Axios Http

This package helps you quickly to build requests for REST API. Move your logic and backend requests to dedicated classes. Keep your code clean and elegant.

Wouldn't it be great if you could just use your back end to validate forms on the front end? This package provides a BaseService class that does exactly that. It can post itself to a configured endpoint and manage errors. The class is meant to be used with a Laravel back end, and it doesn't limit that you need only to work with laravel, Ruby on Rail, Node.js, Express.js, or any other languages.

Take a look at the usage section to view a detailed example on how to use it.

Install

You can install the package via yarn (or npm):

npm install vue-axios-http

yarn add vue-axios-http

Usage

import Vue from 'vue'
import AxiosHttp from 'vue-axios-http'

Vue.use(AxiosHttp)

Nuxt Support

Put it on top of axios module

export default {
  modules: [
    // simple usage
    'vue-axios-http/nuxt',
    // With options
    ['vue-axios-http/nuxt', { errorProperty: 'errors', resetParameter: true }],
    '@nuxtjs/axios',
  ],
  axiosHttp: { errorProperty: 'errors', resetParameter: true },
}

Options

you can overwrite it by adding in the config above.

Note:

baseURL is required.

You can define baseURL at .env just one of them

API_URL=http://localhost::3000/api
API_HOST=http://localhost::3000/api

if your axios already defined in nuxt.config.js

export default {
  axios: {
    baseURL: process.env.API_URL,
  },
}

Advance usage

-------------- Todo --------------

Vue plugins

import Vue from 'vue'
import AxiosHttp from 'vue-axios-http'

Vue.use(AxiosHttp)

Note

Error response must look like: or based on errorProperty from config

{
  "errors": {
    "field": ["The field is required."]
  }
}

It will create $errors object inside components.

Methods are available:

Validator	Description
has(field = null)	check specific field error
first(field)	get message by field name.
missed(field = null)	check if there is no any error of given field name.
nullState(field = null)	Check if null of given field.
any()	check if any errors exist.
get(field)	get specific field.
all()	get all errors.
count()	get errors count.
fill(errors = {})	fill the errors object.
flush()	clear all errors.
clear(field)	clear specific error by field name.
onKeydown(event, 'baseFormName')	event to clear error by event.target.name. (input the has name).

first(field || fields)

const errors = { name: [{ kh: ['This fist name field is required'] }] }

$errors.first('name') // return array
$errors.first('name[0]') // return object like
$errors.first('name[0].kh') // return string like

$errors.first(['name']) // return array
$errors.first(['name[0]']) // return object like
$errors.first(['name[0].kh']) // return string like

Using it with Vuex

1.Create proxies folder or your prefer folder name for this

~/proxies/NewsService.js

import { BaseService } from 'vue-axios-http'

class NewsService extends BaseService {
  constructor(parameters = {}) {
    super('news', parameters)
  }
}

export default NewsService

2.Store

• Create news store

1. actions.js
2. getters.js
3. mutation-types.js
4. mutations.js
5. state

---

actions.js

import { ALL } from './mutation-types'
import { NewsService } from '~/proxies'
import { BaseTransformer, PaginationTransformer } from 'vue-axios-http'
import { pagination, notify } from '~/utils'

const service = new NewsService()

const all = async ({ commit, dispatch }, payload = {}) => {
  const { fn } = payload
  if (typeof fn === 'function') {
    await fn(service)
  }
  try {
    const { data, meta } = await service.all()
    const all = {
      items: BaseTransformer.fetchCollection(data),
      pagination: PaginationTransformer.fetch(meta),
    }
    await commit(ALL, all)
  } catch (e) {
    const data = { items: [], pagination }
    await commit(ALL, data)
    await notify({ response: e })
  }
}

export default {
  all,
}

---

getters.js

export default {
  all: (state) => state.all,
}

---

mutation-types.js

export const ALL = 'ALL'

export default { ALL }

---

mutations.js

import { ALL } from './mutation-types'

export default {
  [ALL](state, payload = {}) {
    const { items = [], pagination = {} } = payload
    state.all = items
    state.pagination = pagination
  },
}

---

state.js

export default () => ({
  all: [],
  pagination: {},
})

How to call in components or pages

• news.vue pages

It can be called in mounted() or asyncData()

• asyncData()

export default {
  async asyncData({ app, store }) {
    const { id = null } = app.$auth.user
    await store.dispatch('news/all', {
      fn: (service) => {
        service
          .setParameters({
            userId: id,
            include: ['categories'],
          })
          .removeParameters(['page', 'limit'])
      },
    })
  },
}

• mounted()

export default {
  mounted() {
    const { id = null } = this.$auth.user
    this.$store.dispatch('news/all', {
      fn: (service) => {
        service
          .setParameters({
            userId: id,
            include: ['categories'],
          })
          .removeParameters(['page', 'limit'])
      },
    })
  },
}

You can set or remove any parameters you like.

Service methods are available

Method	Description
setParameter(key, value)	Set param by key and value
removeParameter(key)	Remove param by key
setParameters({ key: value, key1: value1 })	Set params by key and value
removeParameters([key1, key2])	Remove params by keys
removeParameters()	Remove all params

setParameters()

Set parameters with key/value.

Note: If you to pass query string, as an object that can be response like object format at api side.

Example

const service = new ExampleService()
const parameters = {
  search: {
    first_name: 'Sek',
    last_name: 'Chantouch',
  },
  page: {
    limit: 20,
    offset: 1,
  },
  order: {
    first_name: 'ASC',
    last_name: 'DESC',
  },
  category_id: 6,
}
const { data } = service.setParameters(parameters).all()
this.data = data

Note: A query object above will transform into query string like:

https://my-web-url.com?search[first_name]=Sek&search[last_name]=Chantouch&page[limit]=10&page[offset]=1&order[first_name]=asc&order[last_name]=desc&category_id=6

if setParameter that value is empty or null, it will remove that param for query string

setParameter()

Example 1

const service = new ExampleService()
const { data } = await service.setParameter('page', 1).all()
this.data = data

Expected will be:

{
  "page": 1
}

Example 2

const service = new ExampleService()
const queryString = 'limit=10&page=1&search[name]=hello'
const { data } = await service.setParameter(queryString).all()
this.data = data

Expected will be:

{
  "limit": 10,
  "page": 1,
  "search": {
    "name": "hello"
  }
}

Be sure to use only once in mounted() or asyncData() and asyncData() is only available in NuxtJs

Use service in components

• news/_id.vue pages

import { NewsService } from '~/proxies'

const service = new NewsService()

export default {
  methods: {
    async fetchNews(id) {
      try {
        const { data } = await service.find(id)
        this.detail = data
      } catch (e) {
        console.log(e)
      }
    },
  },
  mounted() {
    this.fetchNews(this.$route.params.id)
  },
}

Validations

Can use vue-vlidator for client-side validator that inspired by Laravel. Chantouch/vue-vlidator

Errors methods available

It can be called by this.$errors.**

Method	Description
all()	To get all errors messages
has(attribute)	To check an attribute as any error
has(attributes)	To check multiple attributes given have any errors
first(attribute)	To get errors message by an attribute
