Usage
Fetch data in react component using useFetchData
hook
import React from 'react'
import ReactDOM from 'react-dom'
import { ApiProvider, useFetchData } from '@one-view/api-client'
export App = () => {
const { data, isLoading, error } = useFetchData('/endpoint')
return (
<div>
{
isLoading && <span>Fetching data...</span>
}
{
error && <span>Error when fetching data</span>
}
{
data && <span>{ data }</span>
}
</div>
)
}
ReactDOM.render(
<ApiProvider host="http://your-api-host">
<App />
</ApiProvider>,
document.getElementById('container')
)
This example will fetch http://your-api-host/endpoint
when App
component is mounted.
Retry Request
By default the client will retry fetching 3 times. It is configurable in couple ways:
In ApiProvider
Adding retry
prop in ApiProvider
will affect all clients inside the component tree.
<ApiProvider host="..." retry={2}>
<App />
</ApiProvider>
In useFetchData
useFetchData
accept config object as second argument. This will override the config passed in ApiProvider
.
const App = () => {
const { data, isLoading, error } = useFetchData("/endpoint", {
retry: 2,
host: "http://other-api-host"
});
return <div>...</div>;
};
Watch for Prop Changes
const App = (props) => {
// re-fetch data if props.code changes
const result = useFetchData(`/endpoint/${props.code}`, {}, [ props.code ])
return <div>...<div>;
}
Sending POST Request
useFetchData
also return an axios instance under client
name. You can use it to send POST or PATCH request.
const App = () => {
return ({ client, data } = useFetchData("/endpoint"));
const update = () => {
return client.post("/update");
};
return <button onClick={update}>...</button>;
};
You can also use useClient
hook if you don't need fetching any data. useClient
accepts config object as parameter.
import { useClient } from "@one-view/api-client";
const App = () => {
const client = useClient({ retry: 2 });
const submit = () => {
return client.post("/submit-form");
};
return <form onSubmit={submit}>...</form>;
};
Include Access Token in Request Header
You can add accessToken
and tokenType
(default to Bearer
) to config object and the client will automatically include Authorization
.
The recommended way to get the access token is by using useAccessToken
hook from @one-view/auth-helpers
package.
import { useFetchData } from "@one-view/api-client";
import { useAccessToken } from "@one-view/auth-helpers"
const App = () => {
const token = useAccessToken();
const client = useFetchData("/endpoint", {
accessToken: token.accessToken,
tokenType: token.tokenType
});
return <form onSubmit={submit}>...</form>;
};

Typescript Integration
This package provides declaration files to use inside typescript project. For better experience, it is recommended to declare interface for the API response and pass it to useFetchData
hook.
import { useFetchData } from '@one-view/api-client'
interface ApiResponse {
id: number
name: string
...
}
const App: React.FC = () => {
// data will be properly typed and can be autocompleted
const { data } = useFetchData<ApiResponse>('/endpoint')
return <div>...</div>
}
