WWT Logger
创建记录器模块是为了记录特定信息。 模板如下所示:
示例: ERROR [2020 年 11 月 19 日星期四 19:14:58 GMT]:数据库连接出现问题
An example of using the logger:
const path = require("path");
const Logger = require("@addesign/wwt-logger)
const logger_instance = new Logger({ dir: path.join(__dirname, "logs") });
const {logType} = logger_instance
为了向日志文件添加条目,请使用以下代码:
logger_instance.set(logeType.ERROR, `something text for log file`, (err) => { callback })
要获取文件,只需使用 get 方法,我们可以使用内置类型:
const {logType} = logger_instance
logger_instance.get(logType.ERROR, (err, data) => { callback })
An example of using a logger to write all logs to one file:
const path = require("path");
const Logger = require("@addesign/wwt-logger")
const loggerConfig = {
dir: path.join(__dirname, "your directory"),
singleFile: true,
singleFileName: "logsFileExample"
}
const instanceLogger = new Logger(loggerConfig)
如果指定了 singleFile,则必须指定 singleFileName。 LoggerConfig 中的 singleFileName 属性不得在文件名末尾包含 ".log"。
An example of using the logger with Express.js:
const path = require("path");
const ExpressLogger = require("@addesign/wwt-logger/express")
...
const loggerConfig = { dir: path.join(__dirname, "your directory") }
app
.use(ExpressLogger(loggerConfig))
.use((req) => {
req.logger.logType // log types
req.logger.get(...)
req.logger.set(...)
});
所有记录器类型:
enum LogTypes {
ERROR = "ERROR",
INFO = "INFO",
WARNING = "WARNING",
DEBUG = "DEBUG",
FATAL = "FATAL"
}

WWT Logger
The logger module was created in order to log specific information. The template looks like this:
Example: ERROR [Thu, 19 Nov 2020 19:14:58 GMT]: Something went wrong with the database connection
An example of using the logger:
const path = require("path");
const Logger = require("@addesign/wwt-logger)
const logger_instance = new Logger({ dir: path.join(__dirname, "logs") });
const {logType} = logger_instance
In order to add an entry to the log file, use the following code:
logger_instance.set(logeType.ERROR, `something text for log file`, (err) => { callback })
To get the file, just use the get method and we can use the built-in types:
const {logType} = logger_instance
logger_instance.get(logType.ERROR, (err, data) => { callback })
An example of using a logger to write all logs to one file:
const path = require("path");
const Logger = require("@addesign/wwt-logger")
const loggerConfig = {
dir: path.join(__dirname, "your directory"),
singleFile: true,
singleFileName: "logsFileExample"
}
const instanceLogger = new Logger(loggerConfig)
If singleFile is specified, then singleFileName must be specified. The singleFileName property in the LoggerConfig must not contain ".log" at the end of the file name.
An example of using the logger with Express.js:
const path = require("path");
const ExpressLogger = require("@addesign/wwt-logger/express")
...
const loggerConfig = { dir: path.join(__dirname, "your directory") }
app
.use(ExpressLogger(loggerConfig))
.use((req) => {
req.logger.logType // log types
req.logger.get(...)
req.logger.set(...)
});
All logger types:
enum LogTypes {
ERROR = "ERROR",
INFO = "INFO",
WARNING = "WARNING",
DEBUG = "DEBUG",
FATAL = "FATAL"
}
