Fuse Download Files
Downloading files from remote locations is not an easy task in mobile devices, but with fuseTools FileSystem, Environment libraries we can easily achieve it.
Here I am gonna show you, how you can use those libraries to download a remote file into the device. Below is the function which will download the files and place it the os specific location in the devices.
var Environment = require('FuseJS/Environment');
var FileSystem = require("FuseJS/FileSystem");
function ShareHandler() {
let imageUrl = '';
var fileName = imageUrl.split('/').pop(); // extract file name from the url
var oReq = new XMLHttpRequest();
oReq.open("GET", imageUrl, true);
oReq.responseType = "arraybuffer";
oReq.onload = function (oEvent) {
var arrayBuffer = oReq.response;
if (arrayBuffer) {
if (Environment.ios) {
let devicePath = FileSystem.iosPaths.temp;
} else (Environment.android) {
let devicePath = FileSystem.androidPaths.externalCache;
}
var path = devicePath + fileName;
FileSystem.writeBufferToFile(path, arrayBuffer) .then(function() {
console.log("Successful write");
}, function(error) {
console.log(error);
});
}
};
oReq.send(null);
}
