Installing axios from npm
With the npm CLI: npm install axios
With the yarn CLI: yarn add axios
Simple GET request using axios
This sends an HTTP GET request from Vue to the npm api to search for all vue packages using the query q=vue, then assigns the total returned in the response to the component data property totalVuePackages so it can be displayed in the component template.
created() {
// Simple GET request using axios
axios.get("https://api.npms.io/v2/search?q=vue")
.then(response => this.totalVuePackages = response.data.total);
}
Example Vue component at https://codesandbox.io/s/vue-axios-http-get-request-examples-ei7l8?file=/app/GetRequest.vue
GET request using axios with async/await
This sends the same GET request from Vue using axios, but this version uses an async function and the await javascript expression to wait for the promises to return (instead of using the promise then() method as above).
async created() {
// GET request using axios with async/await
const response = await axios.get("https://api.npms.io/v2/search?q=vue");
this.totalVuePackages = response.data.total;
}

GET request using axios with error handling
This sends a GET request from Vue to an invalid url on the npm api then assigns the error message to the errorMessage component data property and logs the error to the console.
created() {
// GET request using axios with error handling
axios.get("https://api.npms.io/v2/invalid-url")
.then(response => this.totalVuePackages = response.data.total)
.catch(error => {
this.errorMessage = error.message;
console.error("There was an error!", error);
});
}
Example Vue component at https://codesandbox.io/s/vue-axios-http-get-request-examples-ei7l8?file=/app/GetRequestErrorHandling.vue
GET request using axios with set HTTP headers
This sends the same GET request again from Vue using axios with the HTTP Content-Type header set to application/json.
created() {
// GET request using axios with set headers
const headers = { "Content-Type": "application/json" };
axios.get("https://api.npms.io/v2/search?q=vue", { headers })
.then(response => this.totalVuePackages = response.data.total);
}
