webpack 기반 응용 프로그램에 설치 프로그램을 설치하려고합니다.webpack이있는 Bunyan - shimmed 된 fs에 액세스하려고 시도했습니다.
I가 다음 웹팩 구성 :
{
level: "trace",
path: "/logs/trace.log"
// Logging from external libraries used by your app or very detailed application logging.
},
{
level: "debug",
path: "/logs/debug.log"
// Anything else, i.e. too verbose to be included in "info" level.
},
{
level: "info",
path: "/logs/info.log"
// Detail on regular operation.
},
{
level: "warn",
path: "/logs/warn.log"
// A note on something that should probably be looked at by an operator eventually.
},
{
level: "error",
stream: process.stderr // we pipe error also to stdout
// Fatal for a particular request, but the service/app continues
// servicing other requests. An operator should look at this soon(ish).
},
{
level: "error",
path: "/logs/error.log"
// Fatal for a particular request, but the service/app continues
// servicing other requests. An operator should look at this soon(ish).
},
{
level: "fatal",
path: "/logs/fatal.log"
// The service/app is going to stop or become unusable now.
// An operator should definitely look into this soon.
}
내가 시도 : 빈 심의 빈 파일
그리고 내 로거에 정의 된 다음 스트림에게 있습니다
// these shims are needed for bunyan
alias: {
'dtrace-provider': path.resolve('empty-shim.js'),
"fs": path.resolve('empty-shim.js'),
'safe-json-stringify': path.resolve('empty-shim.js'),
"mv": path.resolve('empty-shim.js'),
'source-map-support': path.resolve('empty-shim.js')
}
내 로거에 액세스하지만이 오류가 발생합니다.
Uncaught TypeError: fs.createWriteStream is not a function
at Logger.addStream (http://localhost:8080/bundle.js:81080:28)
at http://localhost:8080/bundle.js:80958:19
at Array.forEach (native)
at new Logger (http://localhost:8080/bundle.js:80957:26)
at Function.createLogger (http://localhost:8080/bundle.js:82060:13)
at BunyanLogger.getLogger (http://localhost:8080/bundle.js:80479:18)
fs가 빈 파일로 shimmed 된 원인이라고 가정합니다.
어떻게 작동합니까?
