ESP32 SvelteKit - Create Amazing IoT Projects

A simple and extensible framework for ESP32 based IoT projects with a feature-rich, beautiful, and responsive front-end build with Sveltekit, TailwindCSS and DaisyUI. This is a project template to get you started in no time backed by a powerful back end service, an amazing front end served from the ESP32 and an easy to use build chain to get everything going.

It was forked from the fabulous rjwats/esp8266-react project, from where it inherited the mighty back end services.

Tip: This template repository is not meant to be used stand alone. If you're just looking for a WiFi manager there are plenty of options available. This is a starting point when you need a rich web UI.

Features

🦋 Beautiful UI powered by DaisyUI and TailwindCSS

Beautiful, responsive UI which works equally well on desktop and on mobile. Gently animated for a snappy and modern feeling without ever being obtrusive or in the way. Easy theming with DaisyUI and media-queries to respect the users wish for a light or dark theme.

🦖 Low Memory Footprint and Easy Customization by Courtesy of SvelteKit

SvelteKit is ideally suited to be served from constrained devices like an ESP32. It's unique approach leads to very slim files. No bloatware like other popular JS frameworks. Not only the low memory footprint make it ideal but the developer experience is also outstanding letting you customize the front end with ease. Adapt and add functionality as you need it. The back end has you covered as well.

☎️ Rich Communication Interfaces

Comes with a rich set of communication interfaces to cover most standard needs of an IoT application. Like MQTT client, HTTP RESTful API, a WebSocket based Event Socket and a classic Websocket Server. All communication channels are stateful and fully synchronized. Changes propagate and are communicated to all other participants. The states can be persisted on the file system as well. For accurate time keeping time can by synchronized over NTP.

🗄️ WiFi Provisioning and Management

Naturally ESP32 SvelteKit comes with rich features to manage all your WiFi needs. From pulling up an access point for provisioning or as fall back, to fully manage your WiFi networks. Scan for available networks and connect to them. Advanced configuration options like static IP are on board as well.

🗝️ Secured API and User Management

Manage different user of your app with two authorization levels. An administrator and a guest user. Authenticate their API calls with a JWT token. Manage the user's profile from the admin interface. Use at own risk, as it is neither secure without the ability to use TLS/SSL encryption on the ESP32 server, nor very convenient, as only an admin can change passwords.

✈️ OTA Upgrade Service

The framework can provide two different channels for Over-the-Air updates. Either by uploading a *.bin file from the web interface. Or by pulling a firmware image from an update server. This is implemented with the github release page as an example. It is even possible to have different build environments at the same time and the Github OTA process pulls the correct binary.

🏗️ Automated Build Chain

The automated build chain takes out the pain and tears of getting all the bits and pieces play nice together. The repository contains a PlatformIO project at its heart. A SvelteKit project for the frontend code and a mkdocs project for the documentation go alongside. The PlatformIO build tools not only build the SvelteKit frontend with Vite, but also ensure that the build results are gzipped and find their way into the flash memory of the ESP32. You have two choices to serve the frontend either from the flash partition, or embedded into the firmware binary. The latter is much more friendly if your frontend code should be distributed OTA as well, leaving all configuration files intact.

🍦 Compatible with all ESP32 Flavours

The code runs on many variants of the ESP32 chip family. From the plain old ESP32, the ESP32-S3 and ESP32-C3. Other ESP32 variants might work, but haven't been tested. Sorry, no support for the older ESP8266. Go with one of the ESP32's instead.

esp32-sveltekit's Issues

Guide for custom Theme

Hi do you have examples, guides and references on how to create custom themes, colors for the dashboard?

web interface

Help, I can't figure out how to transfer the sensor value to the web interface. You can use a detailed example with an explanation.

ESP32 S2 missing include

Hello,

I have updated my project to the latest version.

I had to adjust one thing in SystemStatus.cpp.

There is a missing include after the condition:

#elif CONFIG_IDF_TARGET_ESP32S2 
#include "esp32/rom/rtc.h"

otherwise I get errors with root["cpu_reset_reason"] = verbosePrintResetReason(rtc_get_reset_reason(0));

What is the constraint on use with ESP8266?

ESP12-E/F have 4MB of memory like entry level ESP32. What are the other constraints against use with ESP8266?

I have 4 different models of hardware we produce and 1 will continue to use an ESP8266.

I’m happy to do some work to help add support for ESP8266 with sufficient memory. Just need a steer.

WebSerial Monitor. Not an Issue, only a contribution of a github newbie

Sorry, I'm only a retired hobbyist and not (yet) familiar with github and don't know how to fork and contribute with pull requests.
But maybe someone is interested in what I did and maybe it would be a nice extension to features.

WebSerial.zip

WebSerialClass inherits from Arduino Print and can be used like Serial.print() and all other print functions.
It opens a WebSocketClient and sends to clients instead to HwSerial.

On the UI side there's a <textarea> element that acts like a Serial Monitor in platformio, where all content received over the WebSocket is printed. Includes toggling Start/Stop button and Clear button.

How to use:
In main.cpp

WebSerialClass WebSerial = WebSerialClass(&server);

void setup()
{
    // start serial and filesystem
    Serial.begin(SERIAL_BAUD_RATE);

    // start ESP32-SvelteKit
    esp32sveltekit.begin();
    WebSerial.begin();
}

Anywhere else

WebSerial.println("7EA08BCEFF31....3EDBB88FC0D5333092E61348397E");

I hope someone likes it. For me it is very helpfull, cause all my serial ports are used.
Probably it needs some professional improvement.

Minimize number of parallel sockets

Right now the Lightstate Demo uses 2 sockets for SSE and WS and need a 3rd socket to update the HTTP pages. PsychicHttp limits the available sockets to 5 crippling the number of devices available for concurrent connections.

1. Create a UnifiedWebSocketServerEndpoint to use only one socket per frontend connection
2. Merge the NotificationEvents (SSE) into this UnifiedWebSocketServerEndpoint
3. Use this additionally as an endpoint for the lightstate demo to show both usecases

TLS handshake crash on esp32-dev platform github OTA update

The error FFFFBD70 seems to point to a memory issue like running out of heap space, but several facts make this a little suspicious. First, I have about 90kB of free heap available before the handshake, and the documentation suggest I need about 42kB in the worst-case scenario. Also, I once had an error clearly indicating I was running out of heap, and this is a different one. I also tried adding the flags suggested here to sdkconfig.defaults, but that did not have an effect.

I will keep investigating this issue myself, but if anybody has a clue about where to look I'll take it.

Thanks.

WIFI with spaces

When I use a space in the WIFI Name I get lots of errors missing terminating " character

So the example in the documentation does not work: -D FACTORY_WIFI_SSID=\"My Awesome WiFi Network\"

When I escape the spaces like -D FACTORY_WIFI_SSID=\"My\ Awesome\ WiFi\ Network\" it builds and uploads, but the device does not connect to my wifi. (might be becouse I did no factory reset)

Crash on MQTTClient error, after new lease

Hi, this is an awesome peace of code, thank you.
Good documentation!
I'm not a professional so it took me some time to learn how it works, but now it's great.

I detected some minor issues:

• NTPSettingsService has still some #ifdef SERIAL_INFO missing
• WebSocketClient does not compile cause of some ESP headers missing, just renamed it to ...h.bak and ...cpp.bak and it compiled.
• In some Serial logs (printf) with IP adresses, .c_str() is missing

And a big issue:

• The system crashes (reboot) each time a new lease is assigned
• I suspect cause of MQTTClient crashes (reboot) on error

I have just the Serial monitor and can't debug.

This is not an issue, more a request:
When using NTP, there is no event to tell me that the time is valid.
I'm using the standard Arduino loop to do some stuff and there I check

tm timeinfo;
if (!getLocalTime(&timeinfo))
{
	Serial.println("Failed to obtain time");
}

It would be nice to have a callback to indicate NTP time is valid.

Thanks
Daniel

heap fragmentation

In some services Strings are used as members.
They are initialized with empty buffer.
As an example WifiSettingsService.h.

// Struct defining the wifi settings in WifiSettingsService.h
typedef struct
{
    String ssid;
    String password;
    bool staticIPConfig;
    IPAddress localIP;
    IPAddress gatewayIP;
    IPAddress subnetMask;
    IPAddress dnsIP1;
    IPAddress dnsIP2;
    bool available;
} wifi_settings_t;

When changing the settings from the GUI, a JSON document is dynamically allocated and the update() is called, where the Strings are set. The String class then allocates memory and copies the content to the memory from the heap, where it lives until it's changed again. But the JSON document (sometimes 2000 to 4000 bytes) is freed after the update.
A gap is left on the heap. It will be used later on, but the heap gets fragmented and the maximum allocatable heap shrinks.

The same happens when using persistancy, when initial data is loaded from FS..

My proposal is to use String.reserve() in the constructor for these members.
The size of the content is known in advance and can be well limited.
So the framework would leave the maximum heap possible to the user and not fragment the heap already at startup.

Getting Started: WebSocket Not Working

I had some trouble but got it to run, so I am just verifying if the solution is correct,
and it might help others too.

When this repo is run, I get message on the browser "Connection to device lost".
Toggling the light using REST is working.
Socket is not working.

I tried this solution and it solves the web socket issue:
https://stackoverflow.com/questions/69350342/svelte-sveltekit-and-socket-io-client-not-working-in-dev-works-in-preview

It says to add to svelte.config.js

const config = {
  kit: {
    vite: {
      resolve: {
        alias: {
          "xmlhttprequest-ssl": "./node_modules/engine.io-client/lib/xmlhttprequest.js",
        },
      },
    },
  },
};

Is this the recommended solution?

Thank you for the great lib.

rename spinner.svelte to Spinner.svelte

Used: release 0.2.1

In the release the file spinner.svelte is present ( src/lib/components). During build a Spinner.svelte is needed. On a Linux machine that is case sensitive for filenames this results in an error.

ESP32C3 - Serial appears to block the application

From discord:

the esp32c3 I'm working with seems to halt execution or something unless there is a serial monitor connected. If I plug it into my PC, it seems to connect to wifi as expected, but the web ui (using the sveltekit build) is not accessible... However the moment I start a serial monitor the UI loads up.

Commenting/removing all references to Serial appears to resolve this issue.

The following files (excluding main.cpp) had Serial lines that were commented:

Maybe unique to the ESP32C3, or the Seeed Studio XIAO ESP32C3 board specifically.

lost connection to webserver

To reproduce

1. Clean build and upload SW.
2. Connect to device ( 192.168.4.1)
3. Login screen shows
4. Do a refresh in browser.
5. You will get an error message in the log window and the connection is lost forever.
   Sometimes I see the error something like" Too many messages in the queue"

ACME? [Feature Request]

Such a cool project, I must come up with a something where I can use this!

...Now that it has stable HTTPS support it would be cool if you also include an ACME-client for pulling certs also!?

There's a library already available that I think might fit:

Wifi state - ap mode or sta mode

Hello, I've been stuck on a topic for some time now, so I thought I might find some help here. I'm using this project, and I've connected a display to my ESP32-S2 where I want to display certain things, for example, weather data.

It should work as follows:

1. When the device is turned on, the AP access data should be displayed on the display.
2. Once the device is connected to a home network (i.e., STA Mode), the access data on the display should be cleared and something else should be displayed.

My problem now is that I'm using the two classes WiFiSettingsService and APsettingsService to solve this. However, I haven't managed to do this because the device first goes into STA mode when starting and then sometimes turns the AP mode on or off. When the device is in STA mode, the AP access data continues to be displayed. Somehow, I'm not getting anywhere. Do you have any idea how I should proceed?

postcss.config.cjs as ESM module

This isn't so much an issue, but something I wanted to share here.

Longer story short, I was having a hard time getting the postcss-remove-class plugin to work with the way postcss.config.cjs was defined.

This ESM approach worked better for me (renamed as postcss.config.js):

import tailwindcss from 'tailwindcss';
import autoprefixer from 'autoprefixer';
import postcssRemoveClasses from 'postcss-remove-classes';

export default {
  plugins: [
    tailwindcss(),
    autoprefixer(),
    postcssRemoveClasses.default('range'),
  ],
}

There may be a solution using the previous format of the file, but I wasn't finding the approach very intuitive 🤷

RMT failed to initilize

If I remove the PROGMEM_WWW option it obviously continues, but I would like to try using the non-spiffs version.
I have a further compilation problem in lightstateservice.cpp on LED_BUILTIN because I use an azdelivery kit v.4 which does not have this definition; I will bypass it by adding an external LED.... but the problem relating to the WWWData.h , I honestly can't understand what's causing it... I seem to have done all the first setup steps correctly.

Thank you in advance for the support

Vite Proxy does not work: »Error: read ECONNRESET«

I try to use the vite proxy to work on the sveltekit code. The board is available at 192.168.1.190, but the vite proxy does not seem to work:

Vite proxy config:

proxy: {
	'/rest': {
		target: 'http://192.168.1.190',
		changeOrigin: true
	},
	'/ws': {
		target: 'ws://192.168.1.190',
		changeOrigin: true,
		ws: true
	}
}

The Vite Server shows this error:

The serial output shows, that there was a request:

The error message seems very general to me, so I do not really have an idea where to expect the issue. Anyone had a similar issue before or an idea what I could check?

I'm using the ESP32_Relay_X8 which is equipet with an ESP32-WROOM-32E.

Read state from FS for custom external rest call

Hello, I would like to save a Json Object in the FileSystem via Http.
I then want to read the values from the FS in my CustomStateService.

What is the best way to do this in the backend? I have already done the frontend part, the id is set and a rest endpoint should be called. But I would like to save this ID in the file system in the backend and then read it somewhere else. For an Http rest call to an external service. Which in turn gives me a Json response and I save it back into the file system.

I'm currently also using my own code to save the result of the external service call in the FS. Can I also use the FSPersisntence for this somehow?

Here is the code I use...

Server stops responding

Thanks for building this great project!

Not sure if this is related to #8, so am opening a new issue.

I did a build with webui in LittleFS, and system works but is quite unstable and server stops responding after a while.

MQTT - Check/Uncheck/Check kills MQTT

After updating to version 0.3.0, I conducted some tests and noticed an issue.
I will describe the conditions to reproduce it:

1. Configured the WiFi network:
   WiFi icon in the status bar displayed correctly.

2. Configured MQTT:
   URI: mqtt://192.168.1.12:1883
   Clean Session? (enable or disable)
   MQTT Status: Connected

3. Disabled the check box "[ ]Enable MQTT" checkbox:
   Applied settings
   MQTT Status: MQTT Disable

4. Enabled MQTT again:
   Checked the "[ X ] Enable MQTT" checkbox
   Applied settings
   MQTT Status: None
   WiFi icon in the status bar changed to WiFiOff
   MQTT stopped functioning
   On the WiFi Station screen, the status remained as "Status: Connected"
   WiFi continued to operate
   MQTT functionality was restored only after performing a RESTART on the System Status screen.

Steps 2, 3, 4 : These steps repeat after the restart.

I conducted this test under two conditions:
a) SDK Version > ESP-IDF v4.4.6-dirty / Arduino v2.0.14
b) SDK Version > ESP-IDF v4.4.4 / Arduino v2.0.9

Error Handling in API Requests

Problem

Currently if a request fails the end user does not get notified of the result of the request.
Most fetch call is wrapped in a try catch that silently logs the error with console.error().

Proposal

An api service, which handles the unsuccessful requests and return a typed response. Something like:

await get<Networks>('/rest/listNetworks')

The service should:

• Fetch the data with appropriate authentication
• Notify the user (maybe via toast service) of any errors that occurred
• Cast the json response to T type
• return the data

Let me know if you are interested in the proposed feature.
