Build an Asynchronous Logging Library with Go
In this code lab, you'll use Go's concurrency tools to build a fully asynchronous logging package. You'll start with a simple, synchronous logger and add new features which allow log messages to be stored with minimal impact on the performance of your application.

Challenge
Create the message channel
In this module, you'll add the primary functionality of the logger. This includes support for thread-safe, asynchronous writes to the log and concurrent error handling. ### Solution To view the solution, run
git diff origin/master..module2-solutionin the Terminal, and pressEnterto see the next lines of the difference.You may also browse the files of the solution by stashing your changes with
git stashand runninggit checkout module2-solutionto switch branches. -
Challenge
Create channels to shutdown logger
Eventually, almost all applications need to exit and they should do so gracefully. In this module, you'll add some additional capabilities to the asynchronous logging package that will allow the log to be shut down while ensuring that no pending messages are lost. ### Solution To view the solution, run
git diff origin/master..module3-solutionin the Terminal, and pressEnterto see the next lines of the difference.You may also browse the files of the solution by stashing your changes with
