SDK to use ACS from Node.js applications

ACS Node SDK

The SDK of ACS for NodeJS

Getting started

git clone git+https://github.com/appcelerator/acs-node-sdk.git
cd acs-node-sdk
npm install

Basic Example

You can get an overview of ACS Node SDK example from examples/basic.js

cd acs-node-sdk/examples
export ACS_APPKEY=YOUR_ACS_TEST_APPKEY
node basic.js

ACS Node SDK Example on Node.ACS

There is another example for ACS Node SDK to show how to run on Node.ACS as a service.

Make sure you have installed Node.ACS command line tool first:

sudo npm -g install acs

Then you can try:

cd acs-node-sdk/examples/over_nodeacs
# Update config.json to fill in your ACS app key
vi config.json
acs run

Open another session and try:

curl -b cookie.txt -c cookie.txt -X POST -F "login=YOUR_USERNAME" -F "password=YOUR_PASSWORD" http://localhost:8080/login
curl -b cookie.txt -c cookie.txt -X GET http://localhost:8080/showMe

ACS Node SDK Basic Usage

Use ACS Node SDK directly

var ACSNode = require('acs-node');
var acsApp = new ACSNode('Your_ACS_APPKEY');

acsApp.usersLogin({
    login: ACS_USERNAME,
    password: ACS_PASSWORD
}, function(err, result) {
    if (err) {
        console.error(err);
        return;
    }
    console.log('Logged in user: %j', result.body);
    acsApp.usersShowMe(function(err, result) {
        if (err) {
            console.error(err);
            return;
        }
        console.log('Show user: %j', result.body);
    });
});

Use ACS Node SDK inner express or http/https NodeJS module

// HTTP call 1 with cookie:
var acsApp = new ACSNode('Your_ACS_APPKEY');

acsApp.usersLogin({
    login: req.body.login,
    password: req.body.password,
    req: req,
    res: res
}, function(err, result) {
    if (err) {
        console.error(err);
        return;
    }
    res.end(result.body);
});

// HTTP call 2 with cookie, after HTTP call 1:
var ACSNode = require('acs-node');
var acsApp = new ACSNode('Your_ACS_APPKEY');

acsApp.usersShowMe(ACS_APPKEY, {
    req: req,
    res: res
}, function(err, result) {
    if (err) {
        console.error(err);
        return;
    }
    res.end(result.body);
});

General RestAPI call

var acsApp = new ACSNode('Your_ACS_APPKEY');

acsApp.post(ACS_APPKEY, '/v1/users/login.json', {
    login: ACS_USERNAME,
    password: ACS_PASSWORD
}, function(err, result) {
    if (err) {
        console.error(err);
        return;
    }

    console.log('ACS returned body: %j', result.body);
    console.log('Cookie string returned: %s', result.cookieString);

    acsApp.get(ACS_APPKEY, '/v1/users/show/me.json', function(err, result) {
        if (err) {
            console.error(err);
            return;
        }
        console.log('ACS returned user: %j', result.body);
    });
});

Session Management

By default, acs-node-sdk will manage sessions for you automatically when you log in and out. You can create a new ACSNode instance for each authenticated session. You can also reuse an existing instance by calling usersLogin() again, however this simply overwrites the existing session cookie and will not log out the previous session.

However, if you'd prefer to manually manage the session cookie, then you can set the autoSessionManagement option to false when the ACSNode instance is created.

var acsApp = new ACSNode('Your_ACS_APPKEY', {
    autoSessionManagement: false
});

This means once you log in, you must track the session cookie yourself:

acsApp.usersLogin({
    login: ACS_USERNAME,
    password: ACS_PASSWORD
}, function(err, result) {
    if (err) {
        console.error(err);
        return;
    }
    
    console.log('Logged in user');
    console.log('Cookie string returned: %s', result.cookieString);
    
    // IMPORTANT! You must set the sessionCookieString or else all privileged calls will fail
    acsApp.sessionCookieString = result.cookieString;
});

Running Unit Tests

To run the unit tests, simply run:

export ACS_APPKEY=ONE_OF_YOUR_ACS_TEST_APPKEY
npm test
