react-axios
Axios Component for React with child function callback. This is intended to allow in render async requests.
Features
- Same great features found in Axios
- Component driven
- Child function callback (error, response, isLoading, makeRequest, axios) => { }
- Auto cancel previous requests
- Debounce to prevent rapid calls.
- Request only invoked on prop change and isReady state.
- Callback props for onSuccess, onError, and onLoading
- Supports custom axios instances through props or a <AxiosProvider ... >
- Create your own request components wrapped using the withAxios({options})(ComponentToBeWrapped) HoC
Installing
Using npm:
$ npm install react-axiosAlso install the required peer dependancies if you have not already done so:
$ npm install axios
$ npm install react
$ npm install prop-typesComponents & Properties

url="" /* url endpoint to be requested - required */
data={} /* post data - optional */
params={} /* queryString data - optional */
config={} /* axios config - optional */
debounce={200} /* minimum time between requests events - optional */
debounceImmediate={true} /* make the request on the beginning or trailing end of debounce - optional */
isReady={true} /* can make the axios request - optional */
onSuccess={(response)=>{}} /* called on success of axios request - optional */
onLoading={()=>{}} /* called on start of axios request - optional */

<Head ... />
<Post ... />
<Put ... />
<Patch ... />Example
Include in your file
import { AxiosProvider, Request, Get, Delete, Head, Post, Put, Patch, withAxios } from 'react-axios'Performing a GET request
// Post a request for a user with a given ID
render() {
return (
<div>
<Get url="/api/user" params={{id: "12345"}}>
{(error, response, isLoading, makeRequest, axios) => {
if(error) {
return (<div>Something bad happened: {error.message} <button onClick={() => makeRequest({ params: { reload: true } })}>Retry</button></div>)
}
else if(isLoading) {
return (<div>Loading...</div>)
}
else if(response !== null) {
return (<div>{response.data.message} <button onClick={() => makeRequest({ params: { refresh: true } })}>Refresh</button></div>)
}
return (<div>Default message before request is made.</div>)
}}
</Get>
</div>
)
}Exposed properties on the child function.
error The error object returned by Axios.
response The response object returned by Axios.
isLoading Boolean flag indicating if Axios is currently making a XHR request.
makeRequest(props) Function to invoke another XHR request. This function accepts new temporary props that will be overloaded with the existing props for this request only.
axios current instance of axios being used.
Custom Axios Instance
Create an axios instance
const axiosInstance = axios.create({
baseURL: '/api/',
timeout: 2000,
headers: { 'X-Custom-Header': 'foobar' }
});Pass down through a provider
<AxiosProvider instance={axiosInstance}>
<Get url="test">
{(error, response, isLoading, makeRequest, axios) => {
...
}}
</Get>
</AxiosProvider>Or pass down through props
<Get url="test" instance={axiosInstance}>
{(error, response, isLoading, makeRequest, axios) => {
...
}}
</Get>Retrieve from custom provider (when you need to directly use axios).
The default instance will be passed if not inside an <AxiosProvider/>.
<AxiosProvider instance={axiosInstance}>
<MyComponent/>
</AxiosProvider>withAxios(Component) HoC
If you need basic access to the axios instance but don't need anything else you can wrap a component using withAxios() higher order component.
const MyComponent = withAxios(class MyComponentRaw extends React.Component {
componentWillMount() {
this.props.axios('test').then(result => {
this.setState({ data: result.data })
})
}
render() {
const data = (this.state || {}).data
return <div>{JSON.stringify(data)}</div>
}
})withAxios(options)(Component) HoC
If you want to create your own component with the full react-axios request options. You can override the initial options supplied to withAxios at any time by passing options prop to your wrapped component. See below on how this works.
const MyComponent = withAxios({
url: '/api/user'
params: {id: "12345"}
})(class MyComponentRaw extends React.Component {
render() {
const {error, response, isLoading, makeRequest, axios} = this.props
if(error) {
return (<div>Something bad happened: {error.message}</div>)
} else if(isLoading) {
return (<div className="loader"></div>)
} else if(response !== null) {
return (<div>{response.data.message}</div>)
}
return null
}
})
