[FIXED] How to use Axios in main.js

Issue

I am learning Vue.js.

I have this code which runs fine :

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

const app = createApp(App).use(store).use(router)

app.mount('#app')

Now I would like to add some import, for example 'axios'. This code does not run :

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import axios from 'axios'

const app = createApp(App).use(store).use(router).use(axios)

app.mount('#app')

The error is:

Uncaught RangeError: Maximum call stack size exceeded

    at merge (utils.js?c532:276)
    at assignValue (utils.js?c532:282)
    at forEach (utils.js?c532:253)
    at merge (utils.js?c532:291)
    at assignValue (utils.js?c532:282)
    at forEach (utils.js?c532:253)
    at merge (utils.js?c532:291)
    at assignValue (utils.js?c532:282)
    at forEach (utils.js?c532:253)
    at merge (utils.js?c532:291)

So how to add some other "use" in the main.js file ? It is certainly very basic but I am a beginner.

Solution

You're using vue 3 and axios is not a plugin (we cannot register it like app.use()) it's a javascript module that could be add to the app instance like :

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import axios from 'axios'

const app = createApp(App).use(store).use(router)

app.config.globalProperties.axios=axios

app.mount('#app')

and in child component reference it like :

this.axios
