It's always have been painpoint when we start with new application from scratch with golang as primary language.
Today, I came across interesting go library to generate scaffold application with golang having MongoDB as backend. You can use any frontend framework (Angular, React or Vue)
Goxygen aims at saving your time while setting up a new project. It creates a skeleton of an application with all configuration done for you. You can start implementing your business logic straight away. Goxygen generates back end Go code, connects it with front end components, provides a Dockerfile for the application and creates docker-compose files for convenient run in development and production environments.
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
The Go programming language is an open source project to make programmers more productive. Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era. No database makes you more productive.
React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable and easier to debug.
Angular is an app-design framework and development platform for creating efficient and sophisticated single-page apps.
How to use
You need to have Go 1.11 or newer on your machine.
go get -u github.com/shpota/goxygen go run github.com/shpota/goxygen init my-app
This generates a project in
By default, a React-based project is generated. You can choose
from Angular, React and Vue by passing
vue to the --frontend flag. For example:
go run github.com/shpota/goxygen init --frontend vue my-app
The generated project is ready to run with docker-compose:
cd my-app docker-compose up
After the build is completed, the application is accessible on http://localhost:8080.You can find more details on how to work with the generated project in its README file.
Structure of a generated project (React-based app)

Files such as unit tests or sample components are not included here for simplicity.
Goxygen generates a basic structure of a project and doesn't force you to use a specific set of tools. That's why it doesn't bring unneeded dependencies to your project. It uses only
mongo-go-driver on the back end side and axios in React and Vue projects. Angular projects use only Angular specific libraries.
