11.-Config-Service
ConfigService helps you to define your configuration in a JSON file.
/**
* Config service
*/
export abstract class ConfigService {
/**
* Config loaded of config service
* An `Observable` that emit whenever config loaded.
*/
readonly configLoaded: Observable<any>;
abstract init(): Promise<any>;
/**
* Gets config
* T Return type of config value.
* @param key Config key;
* @returns config value
*/
abstract getConfig<T>(key: string): T;
/**
* Gets all config keys
* @returns all keys
*/
abstract getAllKeys(): string[];
}
The path of the config file is determined in NarikCore module import.
NarikCoreModule.forRoot({
configFilePath: "assets/app-config.json",
...
}),
Sample Config Data:
{
"modulesMetaDataRoot": "assets/modules",
"dynamicResourcesPath": "assets",
"translationsPath":"assets/i18n"
}
Sample Use Of Config Service:
export class test{
@NarikInject(ConfigService)
private configService: ConfigService;
init()
{
this.configService.configLoaded.pipe(first()).subscribe(() => {
this.moduleRootPath = this.configService.getConfig("modulesMetaDataRoot");
if (!this.moduleRootPath) {
throw new Error("modulesMetaDataRoot is null");
}
this.registerModule();
});
}
}
