How to list all dependents of a Node package

You can use the web npm web site as it lists the dependents for any given package.

Like coffee-script for example:

http://npmjs.org/browse/depended/coffee-script

Or, you could get JSON results for the same query (using curl) (just substitute the name of the package with "sql" in the example:

> curl -g 'http://registry.npmjs.org/-/_view/dependedUpon?group_level=2&startkey=["sql"]&endkey=["sql","ZZZZZZZZZZZZZ"]&skip=0&limit=1000'

Results:

{"rows":[
{"key":["sql","anydb-sql"],"value":1},
{"key":["sql","dbal"],"value":1},
{"key":["sql","ectypes-downstairs"],"value":1},
{"key":["sql","fixr"],"value":1},
{"key":["sql","fixr-compiled"],"value":1},
{"key":["sql","forerunner-postgres-store"],"value":1}
{"key":["sql","pg-dal"],"value":1},
{"key":["sql","relational"],"value":1},
{"key":["sql","sequelize"],"value":1},
{"key":["sql","sql-generate"],"value":1},
{"key":["sql","sqlbox"],"value":1},
{"key":["sql","triplie"],"value":1},
{"key":["sql","voltron-postgres-adapter"],"value":1},
{"key":["sql","worm"],"value":1}
]}

The second value in the key array is the name of the package dependent on the sql package.

This of course only will find other published packages, and doesn’t help find applications, etc. that are using a specific package.

Loading Models in NodeJS

I’d answered a question on StackOverflow about where to put “models” in a NodeJS project. I wanted to elaborate on the simple auto loader I use to load a folder full of models (and I use this pattern other places as well). Normally, I create a folder called models:

image

Inside the Models folder, I have a file called, models.js.

Inside another module (like app.js), I’ve got a line of code that looks like this:

var models = require('./models').initialize(app, services);

While the require (reference) by default looks for a file called index.js in the folder models, I’ve in this case added a simple package.json file with an override:

{
    "main": "./models.js"
}

The reason I do this is that in a tabbed source code editor, having several index.js files can be confusing to see. So, this allows me to name the file something that is more memorable and understandable at a glance.

Inside of the models.js class, I’ve written code to automatically load all of the models (and call an initialize function once for each module):

var initialize = function(app, services) {
    var models = {};
    var currentFile = path.basename(__filename); // just file name
    var modelFiles = fs.readdirSync(__dirname);
    // loop through all of the files in the current directory
    for(var i= 0, len = modelFiles.length; i < len; i++) {
        // ignore this file (via global NodeJS variable)
        if(modelFiles[i] === currentFile ||
            path.extname(modelFiles[i]).toLowerCase() !== '.js') {
            continue;  // skip the current file and anything without a "JS" extension
        }
        // require it
        var model = require(path.join(__dirname, modelFiles[i]));
        // call its intialize
        model.initialize(services, models);
    }
    exports.models = models;
    return models;
};

exports.initialize = initialize;

The logic is simple enough – grab all of the files in the current path, then loop through each, filtering the current file and any that don’t end with “js”. This logic could be adjusted of course to reflect other coding styles and requirements.

Finally, each module is loaded and then an initialize method is called (admittedly, I could make it more robust by checking for the existence of the initialize function before calling it (but in this case, I know each module should be initialized in a particular way).

Added Away/Home to unofficial-nest-api

I just finished adding a new simple feature to control the away status for a structure to my unofficial-nest-api published on GitHub and available as a node package (npm).

Usage is simple as calling setAway or setHome on the nest instance after authentication and a successful status has been returned (see commented calls below).

if (username && password) {
    username = trimQuotes(username);
    password = trimQuotes(password);
    nest.login(username, password, function (data) {
        if (!data) {
            console.log('Login failed.');
            process.exit(1);
            return;
        }
        console.log('Logged in.');
        nest.fetchStatus(function (data) {
            for (var deviceId in data.device) {
                if (data.device.hasOwnProperty(deviceId)) {
                    var device = data.shared[deviceId];
                    console.log(util.format("%s [%s], Current temperature = %d F target=%d",
                        device.name, deviceId,
                        nest.ctof(device.current_temperature),
                        nest.ctof(device.target_temperature)));
                }
            }
            subscribe();
            //nest.setAway();
            //nest.setHome();
        });
    });
}

Nest Thermostat API using Node JS and Nest API Update

I’ve been asked by a few people for more details on the API Nest Labs uses for their thermostats, especially regarding setting data (and not just polling).

The API uses mostly JSON formatted data POSTed to their web servers.

Authentication

To authenticate, POST the username and password, encoded as form url-encoded:

POST https://home.nest.com/user/login HTTP/1.1
Host: home.nest.com
Proxy-Connection: keep-alive
Accept-Encoding: gzip, deflate
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Accept-Language: en-us
Content-Length: {Length}
Accept: */*
Connection: keep-alive
User-Agent: Nest/3.0.1.15 (iOS) os=6.0 platform=iPad3,1

username={email}&password={password}

Adjust the email and password, and the content length to fit. You may need to remove the Accept-Encoding header value if your client cannot accept gzip or deflated responses.

The server responds with a healthy set of basic information (in JSON format):

{
    "is_superuser": false,
    "is_staff": false,
    "urls": {
        "transport_url": "https://{subdomain}.transport.nest.com:443",
        "rubyapi_url": "https://home.nest.com/",
        "weather_url": "http://www.wunderground.com/auto/nestlabs/geo/current/i?query=",
        "support_url": "https://nest.secure.force.com/support/webapp?"
    },
    "limits": {
        "thermostats_per_structure": 10,
        "structures": 2,
        "thermostats": 10
    },
    "access_token": "GIANT TOKEN STRING==",
    "userid": "1234",
    "expires_in": "Wed, 07-Oct-2012 12:08:00 GMT",
    "email": "user@example.com",
    "user": "user.1234"
}

There are a few things you’ll need from the response:

  • transport_url : this is the address for all of the later request that are made. I’d speculate it’s just a specific server in a server farm (likely with server affinity/session)
  • access_token : this is the key for all later requests and grants access to the API
  • userid/user : a unique user ID
  • expires_in : this is the timestamp for when the access token expires

I’m not sure why the “limits” are being sent back to the client.

You can obtain the service URLs at any time:

POST https://home.nest.com/user/service_urls HTTP/1.1
Host: home.nest.com
Authorization: Basic GIANT TOKEN STRING==
Accept-Encoding: gzip, deflate
Accept: */*
Content-Length: 0
Accept-Language: en-us
Connection: keep-alive
Proxy-Connection: keep-alive
User-Agent: Nest/3.0.1.15 (iOS) os=6.0 platform=iPad3,1

Just insert an Authorization header with the access_token value.

The response:

{ "urls": { "transport_url": "https://{subdomain}.transport.nest.com:443", "rubyapi_url": "https://home.nest.com/", "weather_url": "http://www.wunderground.com/auto/nestlabs/geo/current/i?query=", "support_url": "https://nest.secure.force.com/support/webapp?" }, "limits": { "thermostats_per_structure": 10, "structures": 2, "thermostats": 10 } }

Nest labs has a special URL at wunderground.com to access the weather.

One of the first requests you might want to send is to get a complete picture of the system:

GET https://{subdomain}.transport.nest.com:443/v2/mobile/#USER.ID# HTTP/1.1
Host: {subdomain}.transport.nest.com:443
Authorization: Basic GIANT TOKEN STRING==
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: en-us
Connection: keep-alive
X-nl-protocol-version: 1
X-nl-user-id: #USERID#
Proxy-Connection: keep-alive
User-Agent: Nest/3.0.1.15 (iOS) os=6.0 platform=iPad3,1

You’ll make the request to the transport_url and make sure that the Host, Authorization, and X-nl-user-id header values are set appropriately. The Url now must include though:

  • version
  • mobile
  • and the full user id (like user.1234)

So, it will look something like: /v2/mobile/user.1234

It will respond with the mother-load of all JSON payloads. I’ve trimmed the response for my house as I have three thermostats. But the pattern repeats exactly, so it’s easy to extrapolate how the pattern works:

Setting a Temperature

Changing a thermostat’s current set point is easy.

You’ll need the Serial Number (shown as SERIALNUM1 in the JSON above) of the thermostat.

{"target_change_pending":true,"target_temperature":16.11111}

Set the temperature in Celsius.

There’s also a polling subscription that happens. It’s extremely chatty and from the amount of polling it does, you’d think that the UI was doing live graphing of micro-temperature changes.

Essentially, the polling sends a series of keys, with timestamps, representing the various types of data being requested.

It looks something like this:

{ "keys": [{ "key": "user.#USERID#", "version": 209478897, "timestamp": 1324159145000 }, { "key": "user_settings.#USERID#", "version": 370836640, "timestamp": 1337481029003 }, { "key": "user_alert_dialog.#USERID#", "version": -1852987123, "timestamp": 1327246591000 }, { 

It repeats for sections such as “shared”, “message”, “device”, “track”, and more. For my purposes, shared is the winner as it contains the current temperature.

 

Node API

I decided to write a new demonstration application and polish it up a bit, this time using Node.

I’m not going to document the API that I created here (not right now), but here’s a sample of how it can be used:

var username = process.argv[2];
var password = process.argv[3];

if (username && password) {
    username = trimQuotes(username);
    password = trimQuotes(password);
    nest.login(username, password, function (data) {
        if (!data) {
            console.log('Login failed.');
            process.exit(1);
            return;
        }
        console.log('Logged in.');
        nest.fetchStatus(function (data) {
            for (var deviceId in data.device) {
                if (data.device.hasOwnProperty(deviceId)) {
                    var device = data.shared[deviceId];

                    console.log(util.format("%s [%s], Current temperature = %d F target=%d",
                        device.name, deviceId,
                        nest.ctof(device.current_temperature),
                        nest.ctof(device.target_temperature)));
                }
            }
            subscribe();
        });
    });
}

function subscribe() {
    nest.subscribe(subscribeDone);
}

function subscribeDone(deviceId, data) {
    if (deviceId) {
        console.log('Device: ' + deviceId)
        console.log(JSON.stringify(data));
    }
    setTimeout(subscribe, 2000);
}

The example code runs forever. Smile

I’ve included two methods in the API, “get” and “post” which make it simple to call additional web services that I haven’t yet provided.

Update: there’s a npm as well now (Dec 20, 2012)
