COMPONENT(Request& context)
|
|
|
|
:desc
|
|
Defines the default component entrypoint for the current `.uce` file.
|
|
|
|
`component()` and `component_render()` invoke `COMPONENT(Request& context)` by default. Named component entrypoints use `COMPONENT:NAME(Request& context)`.
|
|
|
|
This keeps page rendering and component rendering separate:
|
|
|
|
- direct HTTP requests call `RENDER(Request& context)`
|
|
- WebSocket messages call `WS(Request& context)`
|
|
- component helpers call `COMPONENT(Request& context)` or `COMPONENT:NAME(Request& context)`
|
|
|
|
A file intended only for component reuse can define `COMPONENT()` without defining `RENDER()`.
|
|
|
|
Inside component handlers, props arrive through `context.call`.
|
|
|
|
When you call `component(":NAME", props, context)` or `component_render(":NAME", props, context)`, the runtime resolves `:NAME` against the current `.uce` file instead of requiring the file name again.
|
|
|
|
Examples:
|
|
`COMPONENT(Request& context)`
|
|
`{`
|
|
` <><section><?: component(":BODY", context.call, context) ?></section></>`
|
|
`}`
|
|
|
|
`COMPONENT:BODY(Request& context)`
|
|
`{`
|
|
` <><p><?= context.call["body"] ?></p></>`
|
|
`}`
