Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
@tsed/di
Advanced tools
A package of Ts.ED framework. See website: https://tsed.dev/
You can get the latest release and the type definitions using npm:
npm install --save @tsed/di
Important! TsExpressDecorators requires Node >= 6, Express >= 4, TypeScript >= 2.0 and the
experimentalDecorators
,emitDecoratorMetadata
,types
andlib
compilation options in yourtsconfig.json
file.
{
"compilerOptions": {
"target": "es2016",
"lib": ["es2016"],
"typeRoots": ["./node_modules/@types"],
"module": "commonjs",
"moduleResolution": "node",
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"allowSyntheticDefaultImports": true
},
"exclude": ["node_modules"]
}
Basically, almost everything may be considered as a provider – service, factory, intereceptors, and so on.
All of them can inject dependencies, meaning, they can create various relationships with each other.
But in fact, a provider is nothing else than just a simple class annotated with an @Injectable()
decorator.
Here is a basic usage to declare an injectable service to another one:
import {Injectable} from "@tsed/di";
import {Calendar} from "./models/calendar.js";
@Injectable()
export class CalendarsService {
private readonly calendars: Calendar[] = [];
create(calendar: Calendar) {
this.calendars.push(calendar);
}
findAll(): Calendar[] {
return this.calendars;
}
}
Here's a CalendarsService, a basic class with one property and two methods. The only new trait is that it uses the @Injectable()
decorator.
The @Injectable()
attaches the metadata, thereby Ts.ED knows that this class is a provider.
Now we have the service class already done, let's use it inside a controller:
import {Controller} from "@tsed/di";
import {Post, Body, Get} from "@tsed/schema";
import {CalendarsService} from "./CalendarsService.js";
import {Calendar} from "./models/Calendar.js";
@Controller("/calendars")
export class CalendarCtrl {
constructor(private readonly calendarsService: CalendarsService) {}
@Post()
async create(@Body() calendar: Calendar) {
this.calendarsService.create(calendar);
}
@Get()
async findAll(): Promise<Calendar[]> {
return this.calendarsService.findAll();
}
}
Finally, we can load the injector and use:
import {InjectorService, attachLogger} from "@tsed/di";
import {$log} from "@tsed/logger";
import {CalendarCtrl} from "./CalendarCtrl.js";
async function bootstrap() {
const injector = new InjectorService();
// configure the default logger
attachLogger(injector, $log);
// Load all providers registered via @Injectable decorator
await injector.load();
const calendarController = injector.get<CalendarCtrl>();
await calendarController.create(new Calendar());
// emit event to trigger actions for third parties modules
await injector.emit("$onReady");
// And finally destroy injector and his instances (see injector hooks)
await injector.destroy();
}
bootstrap();
To organize your code Ts.ED DI provide different kind of providers:
@Injectable
,@Service
,@Interceptor
,registerProvider
and registerValue
.See more details on our documentation https://tsed.dev/providers.html
