Troubleshooting issues with axios requests in Vue.js (Nuxt.js) methods

I recently integrated axios into my nuxt.js application. Here is a snippet from my configuration file:

Configuration File: nuxt.config.js

modules: [
  '@nuxtjs/vuetify',
  '@nuxtjs/axios',
],

axios: {
  // proxyHeaders: false
}

Below is a working example of my code:

export default {
  data() {
    return {
      ip: ''
    }
  },
  async asyncData({ $axios }) {
    const ip = await $axios.$get('http://icanhazip.com')
    return { ip }
  }
}

However, the code snippet below is not functioning as expected:

export default {
  data() {
    return {
      ip: ''
    }
  },
  methods: {
    async asyncData() {
      const ip = await this.$axios.$get('http://icanhazip.com')
      this.ip = ip
    }
  } 
}

I am facing an issue with the axios request inside the methods section. Any insights on why this might be happening?

Answer №1

Avoid calling asyncData within the methods object. asyncData is specifically intended for pre-rendering purposes only.

To resolve this issue, simply rename your function to something else:

export default {
  data() {
    return {
      ip: ''
    }
  },
  methods: {
    async fetchData() {
      const ip = await this.$axios.$get('http://icanhazip.com')
      this.ip = ip
    }
  } 
}

Furthermore, if you are using asyncData as shown in your initial example, refrain from initializing "ip" in the data function. The data returned from asyncData will automatically be merged into the data object.

Answer №2

Whenever you load a page, the AsyncData method is triggered. It's important to remember that asyncData is specific to page components in Nuxt. Inside asyncData, you won't have access to the component instance using "this" because it runs before the component is initialized. However, you can still utilize the data returned from asyncData in your template without needing to initialize it in your data.
