I created .env
APP_PORT=3001
DEST=C:\data\formations
I have configService:ConfigService in the controller contractor. I want to get DEST for destination from .env in this code.
@UseInterceptors(FileInterceptor('file', {
storage: diskStorage({
destination: /*here*/ ,
filename: (req, file, cb) => {
const filename: string = path.parse(file.originalname).name.replace(/\s/g, '')
const extension: string = path.parse(file.originalname).ext
cb(null, `${filename}${extension}`)
}
})
}))
When I use this inside this other object I get an error.
You should use the ConfigModule for getting the environment varible.
Check the document: https://docs.nestjs.com/techniques/configuration
If you want to use configuration outside Nest's IoC container, you can try nest-typed-config:
import { selectConfig } from 'nest-typed-config';
import { ConfigModule, FileConfig } from '@/module/config';
const fileConfig = selectConfig(ConfigModule, FileConfig);
@UseInterceptors(FileInterceptor('file', {
storage: diskStorage({
destination: fileConfig.destination,
filename: (req, file, cb) => {
const filename: string = path.parse(file.originalname).name.replace(/\s/g, '')
const extension: string = path.parse(file.originalname).ext
cb(null, `${filename}${extension}`)
}
})
}))
