Full-Stack Web Development with Go

By: Nanik Tolaram, Nick Glynn

Overview of this book

Go is a modern programming language with capabilities to enable high-performance app development. With its growing web framework ecosystem, Go is a preferred choice for building complete web apps. This practical guide will enable you to take your Go skills to the next level building full stack apps. This book walks you through creating and developing a complete modern web service from auth, middleware, server-side rendering, databases, and modern frontend frameworks and Go-powered APIs. You’ll start by structuring the app and important aspects such as networking, before integrating all the different parts together to build a complete web product. Next, you’ll learn how to build and ship a complete product by starting with the fundamental building blocks of creating a Go backend. You’ll apply best practices for cookies, APIs, and security, and level up your skills with the fastest growing frontend framework, Vue. Once your full stack application is ready, you’ll understand how to push the app to production and be prepared to serve customers and share it with the world. By the end of this book, you’ll have learned how to build and ship secure, scalable, and complete products and how to combine Golang with existing products using best practices.

Configuring multiple outputs

Why do we want to configure multiple outputs? Well, it is useful as, during development, it is easier to look at logs locally for troubleshooting purposes, but in production, it’s not possible to look at a log file, as everything will be inside the logging server.

We are going to write a thin layer of wrapper code that will wrap the golog library; the code that we are going to look at is inside the chapter2/ directory, inside the logger/log.go file. The benefit of having a wrapper code for the golog library is to isolate the application for interfacing directly with the library; this will make it easy to swap to different logging libraries when and if required. The app configured the wrapper code by passing the parsed flag to the SetLoggingOutput(..) function.

Build the application by running the following:

make build

Then, run it, passing the flag to true as follows to write the log message to stdout:

./sampledb -local=true
