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-httpyarn add vue-axios-httpUsage
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/apiif 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
$errors.first(['name[0].kh']) // return string likeUsing it with Vuex
1.Create proxies folder or your prefer folder name for this
~/proxies/NewsService.js
import { BaseService } from 'vue-axios-http'
class NewsService extends BaseService {
constructor(parameters = {}) {
super('news', parameters)
}
}
export default NewsService2.Store
Create news store
actions.js
- getters.js
- mutation-types.js
- mutations.js
- state
actions.js
import { ALL } from './mutation-types'
import { NewsService } from '~/proxies'
import { BaseTransformer, PaginationTransformer } from 'vue-axios-http'
import { pagination, notify } from '~/utils'
const service = new NewsService()
const all = async ({ commit, dispatch }, payload = {}) => {
const { fn } = payload
if (typeof fn === 'function') {
await fn(service)
}
try {
const { data, meta } = await service.all()
const all = {
items: BaseTransformer.fetchCollection(data),
pagination: PaginationTransformer.fetch(meta),
}
await commit(ALL, all)
} catch (e) {
const data = { items: [], pagination }
await commit(ALL, data)
await notify({ response: e })
}
}
export default {
all,
}getters.js
export default {
all: (state) => state.all,
}mutation-types.js
export const ALL = 'ALL'
export default { ALL }mutations.js
import { ALL } from './mutation-types'
export default {
[ALL](state, payload = {}) {
const { items = [], pagination = {} } = payload
state.all = items
state.pagination = pagination
},
}state.js
export default () => ({
all: [],
pagination: {},
})How to call in components or pages
- news.vue pages
It can be called in mounted() or asyncData()
asyncData()
export default {
async asyncData({ app, store }) {
const { id = null } = app.$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 = dataNote: 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=6if 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 = dataExpected 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 = dataExpected 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

| 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 |
