fetch in vue 3
First, import the reactive
function from the vue
package. This function allows us to create a reactive object.
Create a new function called fetchData
which will be responsible for fetching the data from the API. This function should be async
to allow for asynchronous operations.
Within the fetchData
function, use the fetch
function to make a network request to the API endpoint. Pass the URL of the API endpoint as a parameter to the fetch
function.
Once the network request is complete, use the json
method to parse the response and extract the data. This method returns a promise, so use the await
keyword to wait for the promise to resolve.
Create a new variable called data
and assign it the parsed data from the response.
Finally, return the data
variable from the fetchData
function.
In the Vue component where you want to use this data, call the fetchData
function and assign the returned value to a reactive property using the reactive
function.
Now, you can access the fetched data in your component using the reactive property. Whenever the data changes, the component will automatically update.
