What should I do if 'TypeError: bind is not a function' occurs when using axios in a Vue application?

In Vue.js applications, it is very common to use axios. Axios is a powerful HTTP request library that allows you to easily send asynchronous HTTP requests. However, when using axios, you will encounter some errors, one of which is "TypeError: bind is not a function". This error is usually caused by the axios version being incompatible with Vue.js.

Let’s take a look at the solution to this error.

First, we need to check the versions of Vue.js and axios. The version of Vue.js should be higher than version 2.0, and axios needs to use version 0.16.2 or higher. If the versions do not match, we need to upgrade axios first to ensure that axios can work properly with Vue.js.

Secondly, in Vue.js, we use the Vue.use() method to install plug-ins. In axios, we need to use the following method to set the default axios option globally:

import axios from 'axios';
axios.defaults.baseURL = 'https://api.example.com';
Vue.prototype.$http = axios;

However, when setting axios in this way, we will encounter "TypeError: bind is not a function "mistake. This is because Vue.prototype.$http has been deprecated in Vue.js 2.0 and has been removed in Vue.js 3.0.

So we need to use Vue.config.globalProperties.$http instead of Vue.prototype.$http. In Vue.js version 3.0, this is a property of the global Vue configuration object, and is the only global object. Use the Vue.config.globalProperties.$http method to set the axios option to avoid the "TypeError: bind is not a function" error.

import axios from 'axios';
axios.defaults.baseURL = 'https://api.example.com';
app.config.globalProperties.$http = axios;

Finally, if you are using Vue.js 2.x version, you can also try installing the vue-axios plug-in. This plugin makes it easier to use axios in your Vue.js application without "TypeError: bind is not a function" errors.

import Vue from 'vue'
import axios from 'axios'
import VueAxios from 'vue-axios'

Vue.use(VueAxios, axios)

The above is how to solve the "TypeError: bind is not a function" error. Hope this helps.
