Integration of cheap-di into React via React.context
There is simple logger.
logger.ts
export abstract class Logger {
abstract debug(message: string): void;
}
export class ConsoleLogger extends Logger {
constructor(private prefix: string) {
super();
}
debug(message: string) {
console.log(`${this.prefix}: ${message}`);
}
}
export class AnotherConsoleLogger extends Logger {
debug(message: string) {
console.log(message);
}
}
Use it in react
components.tsx
import {
Provider,
OneTimeProvider,
SelfProvider,
SelfOneTimeProvider,
} from 'cheap-di-react';
import { Logger, ConsoleLogger } from './logger';
const RootComponent = () => {
return (
<>
<Provider
// will update dependencies on each render
dependencies={[
dr => dr.registerType(ConsoleLogger).as(Logger).with('my message'),
]}
>
<ComponentA/>
</Provider>
<OneTimeProvider
// will use initial dependecies (it uses useMemo under hood)
dependencies={[
dr => dr.registerType(ConsoleLogger).as(Logger).with('my message'),
]}
>
<ComponentA/>
</OneTimeProvider>
{/* shortcut for <Provider dependencies={[ dr => dr.registerType(ConsoleLogger) ]}> ... </Provider> */}
<SelfProvider
// will update dependencies on each render
dependencies={[AnotherConsoleLogger]}
>
<ComponentB/>
</SelfProvider>
<SelfOneTimeProvider
// will use initial dependecies (it uses useMemo under hood)
dependencies={[AnotherConsoleLogger]}
>
<ComponentB/>
</SelfOneTimeProvider>
</>
);
};
const ComponentA = () => {
const logger = use(Logger);
logger.debug('bla-bla-bla');
return 'my layout';
};
const ComponentB = () => {
const logger = use(AnotherConsoleLogger); // because we registered it as self
logger.debug('bla-bla-bla');
return 'my layout';
};
