The web app is stored in SPIFFS (on-board flash memory). The web app is stored in SPIFFS (on-board flash memory).
The web app is a single page app with separate files for js and css, using [jQuery](https://jquery.com) and [Bootstrap](http://getbootstrap.com). It has buttons for On/Off, a slider for brightness, a pattern selector, and a color picker (using [jQuery MiniColors](http://labs.abeautifulsite.net/jquery-minicolors)). Event handlers for the controls are wired up, so you don't have to click a 'Send' button after making changes. The brightness slider and the color picker use a delayed event handler, to prevent from flooding the ESP8266 web server with too many requests too quickly.

The only drawback to SPIFFS that I've found so far is uploading the files is extremely slow, requiring several minutes, regardless of how large the files are. It's so slow that I've been just developing the web app and debugging locally on my desktop (with a hard-coded IP for the ESP8266), before uploading to SPIFFS and testing on the ESP8266.

Installing Installing
----------- -----------
The app is installed via the Arduino IDE which can be [downloaded here](https://www.arduino.cc/en/main/software). The ESP8266 boards will need to be added to the Arduino IDE which is achieved as follows. Click File > Preferences and copy and paste the URL "http://arduino.esp8266.com/stable/package_esp8266com_index.json" into the Additional Boards Manager URLs field. Click OK. Click Tools > Boards: ... > Boards Manager. Find and click on ESP8266 (using the Search function may expedite this). Click on Install. After installation, click on Close and then select your ESP8266 board from the Tools > Board: ... menu.
The app depends on the following libraries. They must either be downloaded from GitHub and placed in the Arduino 'libraries' folder, or installed as [described here](https://www.arduino.cc/en/Guide/Libraries) by using the Arduino library manager.
* [FastLED](https://github.com/FastLED/FastLED)
* [IRremoteESP8266](https://github.com/sebastienwarin/IRremoteESP8266)
* [Arduino WebSockets](https://github.com/Links2004/arduinoWebSockets)
Download the app code from GitHub using the green Clone or Download button from [the GitHub project main page](https://github.com/jasoncoon/esp8266-fastled-webserver) and click Download ZIP. Decompress the ZIP file in your Arduino sketch folder.
The web app needs to be uploaded to the ESP8266's SPIFFS. You can do this within the Arduino IDE after installing the [Arduino ESP8266FS tool](https://github.com/esp8266/Arduino/blob/master/doc/filesystem.md#uploading-files-to-file-system). The web app needs to be uploaded to the ESP8266's SPIFFS. You can do this within the Arduino IDE after installing the [Arduino ESP8266FS tool](https://github.com/esp8266/Arduino/blob/master/doc/filesystem.md#uploading-files-to-file-system).
With ESP8266FS installed run the sketch and then upload the web app using `ESP8266 Sketch Data Upload` command in the Arduino Tools menu. With ESP8266FS installed upload the web app using `ESP8266 Sketch Data Upload` command in the Arduino Tools menu.
Then enter your wi-fi network SSID and password in the .ino file, and upload the sketch using the Upload button.
