Browser support

Works on any browser that supports:

Independent developers have reported success when using FarmBotJS in a Node environment, but we do not test against Node based setups. Issue reports related to NodeJS are highly appreciated.

Installation

NPM

npm install farmbot

Vanilla JS

<script src="./dist/farmbot_single_file.js"></script>
<script>
  var farmbot123 = new fbjs.Farmbot({ token: "foo.bar.baz" });
<script>

Please raise an issue if you require support with other package managers.

Running the test suite (advanced)

npm run test

Login with an API token

Login using your API token from the FarmBot Web App. Click here for instructions on how to generate an API token.

Login example:

import { Farmbot } from "farmbot";

var SUPER_SECRET_TOKEN = "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJ0ZXN0MTIzQHRlc3QuY29tIiwiaWF0IjoxNDU5MTA5NzI4LCJqdGkiOiI5MjJhNWEwZC0wYjNhLTQ3NjctOTMxOC0xZTQxYWU2MDAzNTIiLCJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjMwMDAvIiwiZXhwIjoxNDU5NDU1MzI4LCJtcXR0IjoibG9jYWxob3N0IiwiYm90IjoiYWE3YmIzN2YtNWJhMy00NjU0LWIyZTQtNThlZDU3NDY1MDhjIn0.KpkNGR9YH68AF3iHP48GormqXzspBJrDGm23aMFGyL_eRIN8iKzy4gw733SaJgFjmebJOqZkz3cly9P5ZpCKwlaxAyn9RvfjQgFcUK0mywWAAvKp5lHfOFLhBBGICTW1r4HcZBgY1zTzVBw4BqS4zM7Y0BAAsflYRdl4dDRG_236p9ETCj0MSYxFagfLLLq0W63943jSJtNwv_nzfqi3TTi0xASB14k5vYMzUDXrC-Z2iBdgmwAYUZUVTi2HsfzkIkRcTZGE7l-rF6lvYKIiKpYx23x_d7xGjnQb8hqbDmLDRXZJnSBY3zGY7oEURxncGBMUp4F_Yaf3ftg4Ry7CiA";

let bot = new Farmbot({ token: SUPER_SECRET_TOKEN });

bot
  .connect()
  .then(function () {
    return bot.moveRelative({ x: 1, y: 2, z: 3, speed: 100 });
  });

Sending commands to a FarmBot object

Command example:

bot
  .connect()
  .then(function(bot){
    console.log("Bot online!");
    return bot.emergencyStop(); // You can chain commands.
  })
  .then(function(bot){
    console.log("Bot has stopped!");
  })
  .catch(function(error) {
    console.log("Something went wrong :(");
  });

Basic RPC commands

Call RPC commands using the corresponding method on bot. All RPC commands return a promise.

RPC example:

bot
  .home({ axis: "x", speed: 800 })
  .then(function (ack) {
    console.log("X Axis is now at 0.");
  })
  .catch(function (err) {
    console.log("Failed to bring X axis home.");
  })

Currently supported commands: see the annotated type definitions for available methods and properties.

Using events

Event example:

var bot = Farmbot({ token: '---'});
  bot.on("eventName", function(data, eventName) {
    console.log("I just got an" + eventName + " event!");
    console.log("This is the payload: " + data);
  })
   // "I just got an eventName event!"
   // "This is the payload: any javascript object or primitive"
  bot.emit("eventName", "any javascript object or primitive");
  var eventHandlers = bot.event("eventName");
   // [function(){...}]

Common events

  • "logs": The bot will send logs to this channel.
  • "malformed": When the bot gets a bad RPC command, it will notify you via this channel.
  • "offline": Connection lost. Note: FarmBotJS will try to auto-reconnect.
  • "online": Client is connected and subscribed to bot.
  • "sent": Triggered when the application begins sending a message.
  • "status": Most important. When the REMOTE device state changes (eg: “x” goes from 0 to 100), the bot will emit this event.
  • "sync": A resource on the API has changed.
  • <random uuid>: RPC commands have UUIDs when they leave the browser. When the bot responds to that message, FarmBotJS will emit an event named after the request’s UUID. Mostly for internal use.
  • *: Catch all events (for debugging).
