ts-smart-logger
An implementation of logger at TypeScript (TS 2 compatible).
Installation
First you need to install the npm module:
npm install ts-smart-logger --saveUse
main.ts
import {LoggerFactory} from 'ts-smart-logger/index';
LoggerFactory.configure();
// or
LoggerFactory.configure({"logLevel": 3});
// or
LoggerFactory.configure(require('./config/log/default.json'));
// or
LoggerFactory.configure(require('./config/log/ProductionLoggerConfig').ProductionLoggerConfig);LoggedFirstClass.ts
class LoggedFirstClass {
private logger:ILogger = LoggerFactory.makeLogger(LoggedFirstClass);
public logAtFirstClass() {
this.logger.info(1); // <=> console.info(1);
this.logger.warn(() => 2); // <=> console.warn(2);
this.logger.error(new Error("3")); // <=> console.error(new Error("3"));
this.logger.info(1, 2, 3); // <=> console.info(1, 2, 3);
this.logger.warn(() => [1, 2, 3]); // <=> console.warn([1, 2, 3]);
this.logger.error("Custom error:", new Error("2")); // <=> console.error("Custom error:", new Error("2"));
this.logger.debug((logger:IEnvironmentLogger) => {
// Here may be different kinds of complex calculations, performed only in logging mode
logger.write('Debug log mode enabled: ', 1, 2, 3); // <=> console.debug('Debug log mode enabled: ', 1, 2, 3);
});
this.logger.warn((logger:IEnvironmentLogger) => {
// Here may be different kinds of complex calculations, performed only in logging mode
logger.write('Warn log mode enabled: ', 1, 2, 3); // <=> console.warn('Warn log mode enabled: ', 1, 2, 3);
return [1, 2, 3].length; // <=> console.warn([1, 2, 3].length);
});
}
}config.json
{
"debugLevelPath": "[0-9]+",
"infoLevelPath": ".",
"logLevelPath": ".",
"warnLevelPath": ".",
"errorLevelPath": "[^LoggedFirstClass]",
"logLevel": 3
}Configure the runtime
$$LoggerFactory.storeConfig({"errorLevelPath": "[^Main]", "logLevel": 3})Attention Since the "LoggerFactory" may be shared between the different dependencies we must include the script "npm dedupe" in this case into the package.json:
...
"scripts": {
"postinstall": "npm dedupe && ...",
},
...
