braincloud

brainCloud NodeJS client

Installation

yarn add braincloud
# or
npm install braincloud

NOTE: peer dependency of @react-native-community/async-storage is only needed when used within a React-Native application, see below.

Usage

var bc = require("braincloud")

function authenticated(response) {
    console.log("Did get Authenticated to profileId:" + response.data.profileId);
    var shareable = true;
    var replaceIfExists = true;
    _bc.brainCloudClient.file.prepareUserUpload("tests","dummyFile",shareable,replaceIfExists,)
}
_bc = new bc.BrainCloudWrapper("_mainWrapper");

secret = "aaaaaaaa-bbbb-0000-cccc-111111111111";
appId = "00000";

console.log("Initializing brainCloud");
_bc.initialize(appId, secret, "1.0.0");

console.log("Authenticating anonymously to brainCloud");
_bc.authenticateAnonymous(authenticated);

React-Native Usage

import { BrainCloudWrapper } from 'braincloud';

_bc = new bc.BrainCloudWrapper("_myApp");

secret = "aaaaaaaa-bbbb-0000-cccc-111111111111";
appId = "00000";

console.log("Initializing brainCloud");
_bc.initialize(appId, secret, "1.0.0");

console.log("Authenticating anonymously to brainCloud");
 _bc.authenticateAnonymous(function (response) {
     if (response.status === 200) {
         console.log("Did get Authenticated to profileId:" + response.data.profileId);
     }
});

Running in nodejs without web interface (nodejs server)

If you plan to run this server side in nodejs, it is possible. But it will fail to build at first because of missing web components. Simply put this into your main code file:

// Set up XMLHttpRequest.
XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
window = {
    XMLHttpRequest: XMLHttpRequest
};
XMLHttpRequest.UNSENT = 0;
XMLHttpRequest.OPENED = 1;
XMLHttpRequest.HEADERS_RECEIVED = 2;
XMLHttpRequest.LOADING = 3;
XMLHttpRequest.DONE = 4;
// Set up WebSocket.
WebSocket = require('ws');
// Set up LocalStorage.
LocalStorage = require('node-localstorage/LocalStorage').LocalStorage;
os = require('os');
var configDir = os.homedir() + "/.bciot";
localStorage = new LocalStorage(configDir);
const BC = require('braincloud');

And make sure to have the following NPM dependencies installed:

• braincloud
• node-localstorage
• ws
• xmlhttprequest

Implementation notes

File Upload

The file upload works slightly different in this implementation if not used in the web. Instead of using XMLHttpRequest you need to use XMLHttpRequest4Upload. Also the file object passed into uploadFile call needs to be a Read Stream from the nodes fs module.

var fs = require("fs")
... 
_bc.brainCloudClient.file.prepareUserUpload("test2", fileName, shareable, replaceIfExists, fileSize, function (result) {
    if (result.status == 200) {
        var uploadId = result.data.fileDetails.uploadId;
        var xhr = new XMLHttpRequest4Upload();
        file2 = fs.createReadStream("./someFile.ext");
        file2.size = fileSize;
            xhr.addEventListener("load", transferComplete);
        xhr.addEventListener("error", transferFailed);
        console.log("Uploading file with id:" + uploadId + " (size : " + fileSize + " )");
        _bc.brainCloudClient.file.uploadFile(xhr, file2, uploadId);
    } else {
        console.log("Error preparing for upload, " + result.reason_code );
    }
}
...

Only load and error listeners are triggered in this implementations.

File upload is not yet supported in React-Native.

Sessions

Sessions are not maintained across executions of scripts. i.e. Each script must initialy login.
