  • We will build a Vue Client with Fetch API to make CRUD requests to Rest API in that:.
  • Vue Fetch GET request: get all Tutorials, get Tutorial by Id, find Tutorial by title.
  • Vue Fetch POST request: create new Tutorial.
  • Vue Fetch PUT request: update an existing Tutorial.
  • Vue Fetch DELETE request: delete a Tutorial, delete all Tutorials.
  • This Vue Fetch Client works with the following Web API:.
  • You can find step by step to build a Server like this in one of these posts:.
  • Remember that you need to configure CORS: Access-Control-Allow-Origin: *.

Vue Fetch data from API example

It helps the REST APIs can be accessed by any origin. fetch() returns a Promise that resolves with a Response object, which is fulfilled once the response is available. The Response object we mention above represents the entire HTTP response, it does not directly contain the response body. To get the actual JSON body of the response, we use response.json() method.

We can also access metadata such as headers, status, statusText, type, url from the Response object.

Vue Fetch example – PUT request

The response Promise does not reject on HTTP errors (for example: 404, 500). It only rejects when encountering a network error. So we need to check for HTTP errors with response.ok status and/or response.status properties.

Let’s implement a Vue component to fetch JSON data from API:. get all Tutorials. get Tutorial by Id. find Tutorial by title.

The result will look like this:. Find tutorial by id:. Filter tutorials by title:. Let’s use Vue Fetch POST Json data to create new Tutorial. We use JSON.stringify() on the object before passing it in the body of the request and set:.

"post" for method. "application/json" for the header Content-Type. Check the result by making a Fetch Post Request:. We’re gonna use Vue Fetch with PUT request to update an existing Tutorial. The result will look like this:. Now we implement a Vue component to delete data with Fetch Delete method:. delete a Tutorial. delete all Tutorials. The result could be like this:. With this Vue Fetch example, you’ve known many ways to make GET/POST/PUT/DELETE request using Fetch API (with headers, params, body, form data…) in a Vuejs component.

Instead of Fetch API, you can also use Axios which is a promise-based HTTP Client Javascript library. Kindly visit: – Vue 2 CRUD example with Axios & Vue Router – Vue 3 CRUD example with Axios & Vue Router.

I’ve already described how to make a GET request in Vue.js. We’ll be using axios, a promise based HTTP client for the browser and node.js, to make this API request.
