Do I need this?

This repository is intended for software developers who wish to modify the Farmbot Web App. If you are not a developer, you are highly encouraged to use the publicly available web app.

If you are a developer interested in contributing or would like to provision your own server, you are in the right place.

Farmbot Web API

LATEST STABLE VERSION IS HERE ⭐ ⭐ ⭐

This Repo is RESTful JSON API for Farmbot. This includes things like storage of user data, plant data, authorization tokens and a variety of other resources.

The key responsibility of the API is information and permissions management. This should not be confused with device control, which is done via MQTT.

Developer setup

0. git clone [email protected]:FarmBot/farmbot-web-app.git
1. cd farmbot-web-app
2. Install MongoDB
3. Start Mongo if you have not already done so. (typically via the mongod command)
4. bundle install
5. MQTT_HOST=your_mqtt_server_domain:1883 rails s
6. Go to http://localhost:3000

Provisioning Your Own with Dokku

0. Create a fresh Ubuntu 14 server with Dokku (or just use DigitalOcean)
1. Upgrade to the latest version of Dokku (especially if you are on DigitalOcean- their version is out of date)
2. Install dokku-haproxy plugin: ssh root@YOUR_SERVER dokku plugin:install https://github.com/256dpi/dokku-haproxy.git
3. Deploy: git push dokku@YOUR_SERVER:mqtt
4. Point to correct host/port: ssh dokku@MQTT_SERVER config:set mqtt PORT=3002 DOKKU_NGINX_PORT=3002 WEB_APP_URL=WEBAPP_URL_HERE
5. Expose MQTT port: ssh dokku@MQTT_SERVER ports:add mqtt 1883 web 1883

Config Settings (important)

Here are some of the configuration options you must set when provisioning a new server:

• Encryption keys: Encryption keys will be autogenerated if not present. They can be reset using rake keys:generate. If ENV['RSA_KEY'] is set, it will be used in place of the *.pem files. Useful for environments like Heroku, where file system access is not allowed.
• ENV['MONGO_URL']: URL pointing to running MongoDB instance.
• ENV['DEVISE_SECRET']: Used for devise. Use rake secret to generate a new value.
• ENV['MQTT_HOST']: Host (no port or slashes or anything) of running MQTT gateway. This is required so that Farmbot can know where to connect when given an authorization token.

We can't fix issues we don't know about. Please submit an issue if you are having trouble installing on your local machine.

Generating an API token

You must pass a token string into most HTTP requests under the Authorization: request header.

Here's what a response looks like when you request a token:

{
    "token": {
        "unencoded": {
            "sub": "[email protected]",
            "iat": 1459109728,
            "jti": "922a5a0d-0b3a-4767-9318-1e41ae600352",
            "iss": "http://localhost:3000/",
            "exp": 1459455328,
            "mqtt": "localhost",
            "bot": "aa7bb37f-5ba3-4654-b2e4-58ed5746508c"
        },
        "encoded":
        // THE IMPORTANT PART IS HERE!!:

    }
}

Important: The response is provided as JSON for human readability. For you Authorization header, you will only be using data.token.encoded. In this example, it's the string starting with eyJ0eXAiOiJ...

Via CURL

curl -H "Content-Type: application/json" \
     -X POST \
     -d '{"user":{"email":"[email protected]","password":"password123"}}' \
     https://my.farmbot.io/api/tokens

Via JQuery

Since the API supports CORS, you can generate your token right in the browser.

Here's an example:

$.ajax({
    url: "https://my.farmbot.io/api/tokens",
    type: "POST",
    data: JSON.stringify({user: {email: '[email protected]', password: 'password123'}}),
    contentType: "application/json"
})
.then(function(data){
  // You can now use your token:
  var MY_SHINY_TOKEN = data.token.encoded;
});
