This library implements contextualized logger with
zap.
logger := zapctxd.New(zapctxd.Config{
Level: zap.WarnLevel,
DevMode: true,
StripTime: true,
})
ctx := ctxd.AddFields(context.Background(),
"foo", "bar",
)
logger.Info(ctx, "not logged due to WARN level config")
logger.Error(ctx, "something failed",
"baz", 1,
"quux", 2.2,
)
logger.Important(ctx, "logged because is important")
logger.Info(ctxd.WithDebug(ctx), "logged because of forced DEBUG mode")
logger.AtomicLevel.SetLevel(zap.DebugLevel)
logger.Info(ctx, "logged because logger level was changed to DEBUG")
// Output:
// <stripped> ERROR zapctxd/example_test.go:23 something failed {"baz": 1, "quux": 2.2, "foo": "bar"}
// <stripped> INFO zapctxd/example_test.go:28 logged because is important {"foo": "bar"}
// <stripped> INFO zapctxd/example_test.go:29 logged because of forced DEBUG mode {"foo": "bar"}
