|
|||
|
||||
`peach-web` is built on the Rocket webserver and Tera templating engine. It presents a web interface for interacting with the device. HTML is rendered server-side. Request handlers call JSON-RPC microservices and serve HTML and assets. A JSON API is exposed for remote calls and dynamic client-side content updates (via plain JavaScript following unobstructive design principles). Each Tera template is passed a context object. In the case of Rust, this object is a `struct` and must implement `Serialize`. The fields of the context object are available in the context of the template to be rendered.
|
||||
|
||||
### Configuration
|
||||
|
||||
Configuration variables are stored in /var/lib/peachcloud/config.yml.
|
||||
Peach-web also updates this file when changes are made to configurations via
|
||||
the web interface. peach-web has no database, so all configurations are stored in this file.
|
||||
|
||||
#### Dynamic DNS Configuration
|
||||
|
||||
Most users will want to use the default PeachCloud dynamic dns server.
|
||||
If the config dyn_use_custom_server=false, then default values will be used.
|
||||
If the config dyn_use_custom_server=true, then a value must also be set for dyn_dns_server_address (e.g. "http://peachdynserver.commoninternet.net").
|
||||
This value is the URL of the instance of peach-dyndns-server that requests will be sent to for domain registration.
|
||||
Using a custom value can here can be useful for testing.
