### Building the interface ### Building & uploading the interface
The interface has been configured with create-react-app and react-app-rewired so the build can customized for the target device. The large artefacts are gzipped and source maps and service worker are excluded from the production build. This reduces the production build to around ~200k, which easily fits on the device.

Change to the ['interface'](interface) directory with your bash shell (or Git Bash) and use the standard commands you would with any react app built with create-react-app: The interface will be automatically built by PlatformIO before it builds the firmware. The project can be configured to serve the interface from either SPIFFS or PROGMEM as your project requires. The default configuration is to serve the content from SPIFFS which requires an additional upload step which is documented below.
#### Change to interface directory
```bash
cd interface
```
#### Download and install the node modules
```bash
npm install
```
#### Build the interface
```bash
npm run build
```
> **Note**: The build command will also delete the previously built interface, in the ['data/www'](data/www) directory, replacing it with the freshly built one ready to upload to the device.
#### Uploading the file system image #### Uploading the file system image
The compiled user interface may be uploaded to the device by pressing the "Upload File System image" button: If service content from SPIFFS (default), build the project first. Then the compiled interface may be uploaded to the device by pressing the "Upload File System image" button:

#### Serving the interface from PROGMEM
You can configure the project to serve the interface from PROGMEM by uncommenting the -D PROGMEM_WWW build flag in ['platformio.ini'](platformio.ini) then re-building and uploading the firmware to the device.
Be aware that this will consume ~150k of program space which can be especially problematic if you already have a large build artefact or if you have added large javascript dependencies to the interface. The ESP32 binaries are large already, so this will be a problem if you are using one of these devices and require this type of setup.
A method for working around this issue can be to reduce the amount of space allocated to SPIFFS by configuring the device to use a differnt strategy partitioning. If you don't require SPIFFS other than for storing config one approach might be to configure a minimal SPIFFS partition.
For a ESP32 (4mb variant) there is a handy "min_spiffs.csv" partition table which can be enabled easily:
```yaml
[env:node32s]
board_build.partitions = min_spiffs.csv
platform = espressif32
board = node32s
```
This is largley left as an exersise for the reader as everyone's requirements will vary.
### Running the interface locally ### Running the interface locally
You can run a local development server to allow you preview changes to the front end without the need to upload a file system image to the device after each change. Change to the interface directory and run the following command: You can run a local development server to allow you preview changes to the front end without the need to upload a file system image to the device after each change.

To support OTA programming, enough free space to upload the new sketch and file system image will be required. It is recommended that a board with at least 2mb of flash is used.
By default, the target device is "esp12e". This is a common ESP8266 variant with 4mb of flash: The pre-configured environments are "esp12e" and "node32s". These are common ESP8266/ESP32 variants with 4mb of flash:
![ESP12E](/media/esp12e.jpg?raw=true "ESP12E") ![ESP12E](/media/esp12e.jpg?raw=true "ESP12E") ![ESP32](/media/esp32.jpg?raw=true "ESP32")
The settings file ['platformio.ini'](platformio.ini) configures the platform and board: The settings file ['platformio.ini'](platformio.ini) configures the supported environments. Modify these, or add new environments for the devides you need to support. The default environments are as follows:
``` ```yaml
[env:esp12e] [env:esp12e]
platform = espressif8266 platform = espressif8266
board = esp12e board = esp12e
``` board_build.f_cpu = 160000000L
If you want to build for an ESP32 device, all you need to do is re-configure ['platformio.ini'](platformio.ini) with your devices settings.
![ESP32](/media/esp32.jpg?raw=true "ESP32")
Building for the common esp32 "node32s" board for example requires the following configuration:
```
[env:node32s] [env:node32s]
platform = espressif32 platform = espressif32
board = node32s board = node32s
``` ```
If you want to build for a different device, all you need to do is re-configure ['platformio.ini'](platformio.ini) and select an alternative environment by modifying the default_envs variable. Building for the common esp32 "node32s" board for example:
```yaml
[platformio]
;default_envs = esp12e
default_envs = node32s
