Go Tour

This E-Book by Rashmi Nanda explains about Containerizing Golang Applications Along with Docker and Go’s Multi-Stage Docker as well as Go GraphQL. Also, it deals with Benchmarking Go Programs, how to write Benchmarks in Golang, Test Fixtures in Go, how to write Table Driven tests in Golang and Stress Test Go Packages. YouTube Subscriber Monitoring in real-time is built, Git Hooks and WebSocket is taken care of. Simple profiling is dealt with in detail in this Golang Book.

Chapter 1: This is the introductory chapter of this E-Book dealing with Dockerfiles, GraphQL and Benchmarking in Golang.

Chapter 2: It deals with how to effectively containerize applications of Go using technologies of Docker containerization. Docker basics and how this is useful to developers is known here. Write simplified Dockerfile for Golang applications, with its assistance. This tells as to what Multi-staged Dockerfiles have been. How to build multi-stage Dockerfiles be for apps of Go in simple ways is learnt in this.    

Chapter 3: It explains how to interact with server of GraphQL within codes based on Golang. GraphQL basics, and performing basic questions against GraphQL is learnt here. Focus on a data-retreival sides of GraphQL, backing this with in-memory source of data is stated in this. It expands work done previously in GraphQL, then to look at mutations with implementation properly towards data-sources behind GraphQL API.  

Chapter 4: Have view at benchmarking. How to benchmark programs Go-based? How to do standard tests of benchmarking for too simple functions? Answers to these queries are found out here. Then, move to more core examples prior to looking finally at how to generate flame graphs that is cool looking. See test fixtures in Golang, with writing of table-driven tests and stress test the packages of Go.    

Chapter 5: It talks about using Go installing, testing, and building. This also does simplified test coverages with Go 1.2. It does update and move profiling packages. This discusses lots of technological materials about Golang and Redis.  

Chapter 6: Take look at definition of Git Hooks that are simple within project repository that performs automatically task of linting+ formatting code of Go. See how Golang developers leverage wonderful technology, that is, Makefiles for fortune and fame when Go applications are developed. Know what are WebSockets. Building of simple applications of WebSockets in Go is also stated here. Use WebSockets within own codes Golang based for doing things.

Chapter 7: Create real-time monitoring system of YouTube stats in Go. Create a WebSocket servers. Use WebSockets for communicating in real timing with frontend application, and so interacting with REST API that exists for getting needed subscriber stats. Do interact with a YouTube API for retrieving stats for own channel of YouTube.     

Chapter 8: Concludes this E-Book series on Golang.
