开发模式的话是否有读取环境文件或者配置文件的方式

[Cosmo]

Describe the bug

我设置了环境变量为：
NODE_ENV=development # Node环境，testing或development
PHALA_MODULE=fetch # 启动的组件，fetch, trade, lifecycle
PHALA_LOGGER_LEVEL=debug
PHALA_DB_PREFIX=/var/data # 数据库位置
PHALA_MAIN_CHAIN_ENDPOINT= # 平行链Websocket节点地址，暂不需要
PHALA_CHAIN_ENDPOINT=wss://127.0.0.1/ws # Phala Websocket节点地址
PHALA_REDIS_ENDPOINT=redis://127.0.0.1:6379/ # redis地址
试过echo 变量有显示

按照文档说明如果进入开发的模式项目代码根目录：
npm install
pnpm db_init
显示：

}

因为看到你今天的文档有说环境文件，我想每次有export很长也很麻烦。
如果执行export NODE_ENV='development' && export PHALA_LOGGER_LEVEL='debug' && export PHALA_MODULE='fetch' && export PHALA_DB_PREFIX='/var/data' && export PHALA_MAIN_CHAIN_ENDPOINT='wss://127.0.0.1/ws' && export PHALA_CHAIN_ENDPOINT= && export PHALA_REDIS_ENDPOINT='redis://127.0.0.1:6379/' && export PHALA_ENABLE_HTTP_KEEPALIVE='true' && export PHALA_PARALLEL_BLOCKS='50' && export PHALA_DEV_SKIP_RA='true' && pnpm db_init这样是可以没有错误的。

就不能有个配置文件吗？
