加载.env文件

.env

aaa = "bbb"
ccc = ddd
eee  = 123
ffffff="HELLO
WORLD"

加载env

process.loadEnvFile();
console.log(Object.entries(process.env).filter(([key]) => ["aaa", "ccc", "eee", "ffffff"].includes(key)));

日志

[  [ 'aaa', 'bbb' ],
  [ 'ccc', 'ddd' ],
  [ 'eee', '123' ],
  [ 'ffffff', 'HELLO\nWORLD' ]
]

loadEnvFile(), 可以设置一个文件路径, 比如

process.loadEnvFile("aaa");

也就是说文件名随意啦, 文件路径也随意
