# TS Project (Template for TypeScript) # CUBETIQ Express Server
- Express
- TypeScript - TypeScript
- TS Node Dev - Decorators
- Husky
- Prettier # Getting Start
- ESLint
- Add code into your `index.ts`
```ts
import "reflect-metadata"
import { createServer } from "http"
import server from "./server"
const app = server.instance
const httpServer = createServer(app)
httpServer.listen(process.env.PORT || 3000, () => {
console.log(`Server listening on port: 3000`)
})
```
- Create `server.ts`
```ts
import { Request, Response } from "express"
import { Application } from "./application"
import { Controller, Get } from "./decorators"
@Controller("/index")
class IndexController {
@Get()
public async index(req: Request, res: Response) {
res.json({
status: 200,
})
}
}
class Server extends Application {
get controllers(): any[] {
return [IndexController]
}
}
export default new Server()
```
