Below is a quick set of examples to show how to send HTTP POST requests from Vue to a backend API using the axios HTTP client which is available on npm.

Other HTTP examples available:

• Vue + Axios:GET
• Vue + Fetch:GET, POST
• React + Fetch:GET, POST
• React + Axios:GET, POST
• Angular:GET, POST

Installing axios from npm

With the npm CLI: npm install axios

With the yarn CLI: yarn add axios

Simple POST request with a JSON body using axios

This sends an HTTP POST request to the Reqres api which is a fake online REST api that includes a generic /api/<resource> route that responds to POST requests for any <resource> with the contents of the post body and a dynamic id property. This example sends an article object to the /api/articles route and then assigns the id from the response to the vue component data property articleId so it can be displayed in the component template.

created() {
  // Simple POST request with a JSON body using axios
  const article = { title: "Vue POST Request Example" };
  axios.post("https://reqres.in/api/articles", article)
    .then(response => this.articleId = response.data.id);
}

POST request using axios with async/await

This sends the same POST 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() {
  // POST request using axios with async/await
  const article = { title: "Vue POST Request Example" };
  const response = await axios.post("https://reqres.in/api/articles", article);
  this.articleId = response.data.id;
}
