This repository has been archived by the owner. Because of these we are using rn-fecth-blob library forked by joltup.

Why we are using?

We are using this library for services response and sending large files(video, image etc.)

Where we are using?

We are using under utils and services folders in our projects.

For Example: app > services > serviceUtils.js

How we are using?

    <!-- app > services > serviceUtils.js -->

    import RNFetchBlob from 'rn-fetch-blob';


    const Fetch = RNFetchBlob.polyfill.Fetch;

    const myFetch = new Fetch({
        // enable this option so that the response data conversion handled automatically
        auto: false,
        trusty: false,
        // when receiving response data, the module will match its Content-Type header
        // with strings in this array. If it contains any one of string in this array,
        // the response body will be considered as binary data and the data will be stored
        // in file system instead of in memory.
        // By default, it only store response data to file system when Content-Type
        // contains string `application/octet`.
        binaryContentTypes: [
            'image/',
            'video/',
            'audio/',
            'foo/',
        ]
    }).build();

    GLOBAL.tmpFetch = myFetch;
    GLOBAL.fetch = function (uri, options, ...args) {
        return GLOBAL.tmpFetch(uri, options, ...args).then((response) => {
            return response;
        });
    };
