Class EnvConfig

Example

import { DIContainer } from '@famir/common'
import { VALIDATOR, Validator, AjvValidator, JSONSchemaType } from '@famir/validator'
import { CONFIG, Config, EnvConfig, ConfigData } from '@famir/config'

// Get container singleton.
const container = DIContainer.getInstance()

// Register dependencies in container
AjvValidator.register(container)
EnvConfig.register(container)

// Resolve dependencies from container
const validator = container.resolve<Validator>(VALIDATOR)
const config = container.resolve<Config>(CONFIG)

// Define your configuration interface
interface ServerConfig extends ConfigData {
  PORT: number
  SECRET: string
}

// Define your configuration schema
const serverConfigSchema: JSONSchemaType<ServerConfig> = {
  type: 'object',
  required: ['PORT', 'SECRET'],
  properties: {
    PORT: { type: 'number', default: 3000 },
    SECRET: { type: 'string' }
  },
  additionalProperties: false,
} as const

// Add schema to validator
validator.addSchema('server-config', serverConfigSchema)

// Get parsed and validated configuration object
const configData = config.get<ServerConfig>('server-config')

// TypeScript knows this is ServerConfig
console.log(configData.PORT)
