Index.js application/javascript 40 B T19:08:48.000Z We will then use our first function in the promises.

We will write a function that will run when the data comes back.then() method on it.then() takes a callback function that will run when the data comes back. It's like asking your friend, 'What's the weather like outside?' and she says, 'I don't know right now, but I PROMISE I will get that information for you' She goes out side, comes back, and THEN tells you what the weather is. A promise that it will give us data eventually. get() assigning our lukeSkywalker variable the actual data, it returns a promise. Your JavaScript file and the request for the data are happening AT THE SAME TIME!!! Instead of. This is because Axios is utilizing AJAX's synchronous abilities. If we do this, however, we will see Promise axios.get('the url') We might be tempted to do something like this: //app.js get() method to request the data.get() only requires a string that is the url. We want that information to be available to our apps, and we'll use the axios library to do that. You can also request data on just one person at a time like this:

If you go to that url, you will see an array of people. would suggest that you want a list of the people. The data you wish to request will be specified by the parameters given in the url. In this one, different urls will give you different data. Often times you will need to read some documentation to understand how an api works. We can request information for all sorts of Star Wars stuff. We will be using Star Wars API for a bit because it's free and easy. For now, set up a node environment with the following commands.

AxiosĪxios is an NPM package, so we will need to install it into whatever project we are working on. It's not too difficult because the two are structured the same. Axios will take care of turning JSON in JavaScript for us. It's pretty much a JavaScript object with a few key differences. In the past, data was sent in XML (The X in AJAX). Within the context of this class, it will be servers communicating with our stuff.įor example, we can have our app ask for weather data from a weather API. We don't want to bloat your apps with useless library code.' APIsĪPI is a very general term used to describe applications talking with each other. In the creators words, 'In general we resist adding features that can be implemented in userland. If jQuery and Angular both have their own, why doesn't React? Angular has a $http service that does this same thing. Axios's whole job is to help us with these calls.

We will learn how to use Axios and Axios's methods. Many library's created solutions to preform the common functions needed.

#Axios cdn unpkg code

Previously, there was a lot of code required to make these requests.

Proper action (like page update) is performed by JavaScript.

The server sends a response back to the web page.

The XMLHttpRequest object sends a request to a web server.

An XMLHttpRequest object is created by JavaScript.

An event occurs in a web page (the page is loaded, a button is clicked).

The steps an AJAX call makes are the following:

#Axios cdn unpkg update

This means that it is possible to update parts of a web page, without reloading the whole page.Īsynchronously means that it's happening at the same time as your app is loading or doing other tasks. If those two statements made sense to you, click here AJAXĪJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes.

There are a few acronyms in those two statements that should be understood before getting too deep in how to use Axios. We will being using to make requests for data in the form of JSON. Axios is a JavaScript library that helps us make AJAX calls to APIs.
