Sending Requests with Fetch

With Interceptors

You can use fetch as you regularly do using this method

import SuperTokensRequest from 'supertokens-react-native';

const SESSION_EXPIRED_STATUS_CODE = 440;

// call this when your app starts
SuperTokensRequest.init("/refresh", SESSION_EXPIRED_STATUS_CODE, true);

async function doAPICalls() {
    try {
        // make API call as usual
        let fetchConfig = { 
            // ... 
            credentials: "include"
        };
        let response = await fetch("/someAPI", fetchConfig);

        // handle response
        if (response.status !== 200) {
            throw response;
        }
        let data = await response.json();
        let someField = data.someField;
        // ...
    } catch (err) {
        if (err.status === SESSION_EXPIRED_STATUS_CODE) {
            // show login screen
        } else {
            // handle error
        }
    }
}

Be sure to add credentials: 'include' in the fetchConfig

Without Interceptors

If the viaInterceptor option is false you need to replace all your fetch calls as shown below.

The fetch function: API Reference

SuperTokensRequest.fetch("/someAPI", config);

• Used to send a request to your API endpoint
• Treat it like a regular fetch call
• There are other functions to specifically call get, post, delete and put methods. They can be seen in the API reference page.

import SuperTokensRequest from 'supertokens-react-native';

const SESSION_EXPIRED_STATUS_CODE = 440;
SuperTokensRequest.init("/refreshTokenURL", SESSION_EXPIRED_STATUS_CODE, false);

async function doAPICalls() {
    try {
        // make API call as usual
        let fetchConfig = { 
            // ... 
            credentials: "include"
        };
        let response = await SuperTokensRequest.fetch("/someAPI", fetchConfig);

        // handle response
        if (response.status !== 200) {
            throw response;
        }
        let data = await response.json();
        let someField = data.someField;
        // ...
    } catch (err) {
        if (err.status === SESSION_EXPIRED_STATUS_CODE) {
            // show login screen
        } else {
            // handle error
        }
    }
}

Be sure to add credentials: 'include' in the fetchConfig
