Works on any browser that supports:
- Native Promise objects.
- Websockets.
- JSON (any browser made after 1942).
It is theoretically possible to run FarmBotJS in a Node environment, but we do not test against Node based setups.
npm install farmbot
Raise an issue if you require support with other package managers such as Bower. We don't support them currently, but can if there is a need.
Login using your API token from the Farmbot Web App.
Click here for instructions on how to generate an API token
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 });
});
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 :(");
});
Call RPC commands using the corresponding method on bot
. All RPC commands return a promise. Timeout is set at 6000 ms
by default and can be reconfigured by changing the bot timeout
propery on instantiation or via bot.setState("timeout", 999)
.
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
var bot = Farmbot({uuid: '---', 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(){...}]
status
: Most important. When the REMOTE state changes (eg: "x" goes from 0 to 100), the bot will emit this event.*
: Catch all events (for debugging).ready
: Client is connected and subscribed to bot.sync/:resource_name/:resource_id
: A resource on the API has changed.logs
: The bot will send logs to this channel, usually fromSTDOUT
on the device.disconnect
: Connection lost. Note: FarmbotJS will try to auto-reconnect.malformed
: When the bot gets a bad RPC command, it will notify you via this channel.change
: The bot object's (local) internal state has changed, usually as a result of FarmBotJS configuration updates.<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.
The bot object keeps all state in one place for sanity. This includes things like configuration options, current position, etc. All updates to the bot's state are broadcast with a change
event, that reports current and previous state value as it changes.
bot.getState()
: Get copy of Farmbot status variables (read only).bot.setState(name, value)
: Set state configuration 'A' to value 'B'. Ex:bot.setState('uuid', '---')
. Emits achange
event.
