integration with ESP32 WebServer - A complete Platformio project that integrates ESP32 WebServer with compressed OTA self-updates.

Provided features:

a very basic html form accessible via http://esphost/update
uploading compressed/uncompressed firmware images
uploading compressed/uncompressed file system images
trigger downloading image file from a remote URL and initiate self-update from a download stream (both compressed/uncompressed images supported)
integrated PlatformIO script for on-the-fly compression and uploading firmware images

Edit one of the examples provided:

set you WiFi creds
with PlatformIO build and flash the the code via serial for the first time (pio run -t upload, pio run -t uploadfs)
run console monitor, it will show an ip address once WiFi is connected
open the browser and specified URL (http://esphost/update)
upload zlib compressed firmware
or specify remote URL to download and update the fw image from
or use platformio's env's to do automated build/compress/upload fw tests
- edit platformio.ini's section [env:flashz_ota] and set your controller's IP address
- build and upload compressed FW image via platformio pio run -t upload -e flashz_ota
- build and upload compressed FS image via platformio pio run -t uploadfs -e flashz_ota

In case of issues you can build a pretty much verbose debug version of the lib pio run -e flashz_debug -t upload
