log4ngx is a Typescript logging framework for Angular projects, based on concepts used in Log4j, Log4net, etc.
Current Status
The library is now complete enough to be used in production if theConsoleAppender
andLocalStorageAppender
are sufficient for your needs. Documentation is being completed in the repository and will be updated as progress is made - as soon as it is in a reasonably complete state, a proper link will be made available here.Until then, the demo project contains examples of configuring and using the library.
The LogService
is the factory with which you instantiate Loggers
in each of the components,
services, etc, in which you wish to log messages. Behind the scenes, it also orchestrates the
dispatch of messages from the Loggers
to the appropriate Appenders
.
The LogService
is configured using an instance of the LogServiceConfig
, typically created in
your application's main module. The configuration defines the parameters used with each Appender
and how each Appender
relates to the various Loggers
.
Loggers
provide access to the methods for logging messages at the required Level
. Each class -
i.e. component, module or service - will usually define its own Logger
which will identify that
class within any messages logged via it.
Appenders
are responsible for sending log entries to the underlying target or service.
Configuration will normally depend on the target/service, but all Appenders
are configured with
the layout format for messages logged to them.
