sls-logger v1.0.12

Logger for Aliyun SLS

The nodejs logger for aliyun SLS with minimum dependencies.

Configuration

Note: if your configuration is incorrect(fail to get logstore), all logs will be written to stdout.

Usage

const logger = new SlsLogger({
  endpoint: "example.cn-hangzhou.log.aliyuncs.com",
  accessKey: "your_access_key",
  accessSecret: "your_access_secret",
  logstore: "your_logstore",
  source: "test",
  topic: "test",
  compress: true,
  level: "INFO",
  disabled: true,
});

logger.info(
  "Hello world!",
  new Date(),
  function () { "abc"; },
  { a: 1, b: { c: 1 }, d: "123", e: false },
  new Object(),
  [1, 2, 3, "abc", false, null, undefined, new Error("error1")],
  SlsLogger.createField("module", "main"),
  1234,
  true,
  null,
  undefined,
  new Error("error2")
);

And you can pass a function as log message generator to improve performance; it will not be called unless the log level is enabled.

logger.debug(
  () => "Debug message from generator.",
  SlsLogger.createField("module", "debug")
);
// Set log level on the fly, e.g. through user signal or rest api.
logger.setLevel("DEBUG");
