In this quick tutorial we’ll see by example how to consume a third-party API using Axios inside an Ionic 4 project based on TypeScript and React. We’ll see how to:
- Install and use Axios for sending HTTP GET requests in TypeScript and React,
- Consume a third-party REST API,
- Use React Hooks like useState and useEffect,
- Display the data using IonList and IonItem components,
- Create buttons using IonButton.
The useState() and useEffect() methods are built-in React Hooks introduced in React 16.8+; they enable developers to use state and other React features in functional React components.
React Slot Machine
Let’s get started with the prerequisites!
You need to have the following:
- Node and NPM installed on your machine,
- Knowledge of TypeScript and React,
- Ionic CLI v5+ and a Ionic/React project.
We’ll make use of a the third-party API available from NewsAPI.org. You should register for a free account and get an API key to access the service otherwise you can also consume any available REST API of your choice.
In this step, we’ll see how to install Axios in our Ionic/React project.
Provided that you have already created your Ionic/React project, head back to your terminal and navigate inside the project’s root folder and install Axios from npm as follows:
Step 2 – Sending an HTTP GET Request with Axios
In this step, we’ll use Axios to send a GET request for consuming the third-party API.
If you have generated your Ionic project based on the sidemenu template, you’ll already have a home page.
Go ahead and open the src/pages/Home.tsx file, and import the necessary APIs i.e axios and IonButton as follows:
Next, define the apiKEY and endpoint variables:
Next, define the following method
Next, define the sendGetRequest() method as follows:
We call the axios() method to send a GET request to the REST API endpoint.
Step 3 – Building the UI with React Hooks (useState & useEffect) and Ionic Components (IonList, IonItem and IonButton)
In this step, we’ll build the UI of our home page. We’ll use Ionic components such as IonList, IonItem and IonButton, React Hooks such as useState and useEffect.
Inside the HomePage functional component and call the useState method to create a state variables named items as follows:
useState() returns the state variable, which has the empty array as its initial value and a function that we can use to change the value of the variable. We use destructuring assignment to unpack the values from the returned pair into distinct variables (i.e. articles and setArticles()).
Next, call the sendGetRequest() method inside the useEffect hook to consume the REST API:
We use use the useEffect() hook to perform a side effect in our component. The side effect is consuming data from the REST API.

The useEffect() hook is equivalent to calling the componentDidMount, componentDidUpdate and componentWillUnmount lifecycle methods combined in class-based components.
Next, itertate over the items array and render the data fetched from the REST API as folows:
This is a screenshot of the home page UI:
Concusion
In this quick example, we’ve seen how to use Axios to send GET requests to consume a REST API inside an Ionic/React app based on TypeScript.
We’ve used React Hooks like useState and useEffect and Ionic 4+ components like IonList, IonItem and IonButton.

Usage
Props
The following props can be used to modify the slot machine's style and/or behaviour:
| Prop | Type | Opt/Required | Default | Note |
|---|---|---|---|---|
text | String|Number | Required | 0 | The text the slot machine animates to. |
width | Number | Optional | 37 | The width of each slot. |
height | Number | Optional | 50 | The height of each slot. |
padding | Number | Optional | 4 | minimum number of slots. Added slots will be filled with 'defaultChar' |
duration | Number | Optional | 2000 | The total time of the animation of all the slots. |
delay | Number | Optional | 4 | Time to wait since componentDidMount until animation begins. |
slotInterval | Number | Optional | 500 | The added animation time per slot. last slot animation time = 'duration'. |
defaultChar | Number | Optional | 0 | The default character to be used until animation starts & with 'padding' |
range | String | Optional | 9876543210 | The range of characters to be used when animating the slot machine. |
initialAnimation | Boolean | Optional | true | Should initial animation be activated or only subsequent text changes animations |
renderTextContent | Function | Optional | (char, index, range) => char | Allows replacing the inner content of the Text element |
renderContent | Function | Optional | (char, index, range) => char | Allows replacing the entire Text element with your own implementation |
styles | Object | Optional | {} | Allows overriding each of the inner components (container, slotWrapper, slotInner, innerBorder, outerBorder, overlay, text) |
useNativeDriver | Boolean | Optional | false | Enable use of NativeDriver on Animation. See https://facebook.github.io/react-native/docs/animations.html#using-the-native-driver |
