I'm currently exploring the world of Vue.js and could use some advice.
When making a GET request using the axios package, I would like to display a preloader for the entire page until all the data has been loaded. While I know this is a common task in Vue.js, I'm interested in learning how it's typically approached.
To create the preloader, I've developed a new component but I'm feeling a bit confused. How can I call that component from another one and make it visible at a specific time?
To display a preload user interface before making multiple requests using axios and the all & spread methods, you can follow this approach. First, show the preload UI with an animation, then execute your requests concurrently by using axios.all. Once all requests are completed, utilize the then method to hide the preload UI. Here is an example:
// Display preload UI
showSpinnerAnimation();
// Execute requests in parallel
axios.all([
axios.get('https://examplelink'),
axios.get('https://anotherlink')
])
.then(axios.spread(function (response1, response2) {
// Handle responses after both requests are finished
console.log('Response from first link', response1.data);
console.log('Response from second link', response2.data);
// Hide preload UI
hideSpinnerAnimation();
}));
Axios operates in a different manner compared to ajax. It can be described as an advanced version of the javascript ajax function.
Here's a brief example of using axios:
const axios = require('axios');
// Making a request for a user with a specific ID
axios.get('/user?ID=12345')
.then(function (response) {
// handling success
console.log(response);
})
.catch(function (error) {
// handling errors
console.log(error);
})
.then(function () {
// always executed
});
// Alternatively, the same request can be made like this
axios.get('/user', {
params: {
ID: 12345
}
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
})
.then(function () {
// always executed
});
// Interested in using async/await? Just add the `async` keyword to your outer function/method.
async function getUser() {
try {
const response = await axios.get('/user?ID=12345');
console.log(response);
} catch (error) {
console.error(error);
}
}
