Go-Mongodb-REST-boilerplate

This repo can be used as a starting point for backend development with Golang. It comes bundled with Docker. The development environment uses docker-compose to start dependent services like mongo.

A few things to note in the project:

• Github Actions Workflows - Pre-configured Github Actions to run automated builds and publish image to Github Packages
• Dockerfile - Dockerfile to generate docker builds.
• docker-compose - Docker compose script to start service in production mode.
• Containerized Mongo for development - Starts a local mongo container with data persistence across runs.
• Mongo Driver - MongoDB supported driver for Go.
• Gorilla Mux - HTTP request multiplexer.
• jwt-go - Implementation of JWT Tokens.
• Validator - Package validator implements value validations for structs.

• .env file for configuration - Change server config like app port, mongo url etc
• File Uploads - io package provides interfaces to I/O primitives.
• httptest - Utilities for HTTP testing.

Installation

1. Clone this repo

$ git clone git@github.com:umangraval/Go-Mongodb-REST-boilerplate.git your-app-name
$ cd your-app-name

2. Install dependencies

$ go mod vendor

Development

Start dev server

Starting the dev server also starts MongoDB as a service in a docker container using the compose script at docker-compose.yml.

$ go run main.go routes.go

Running the above commands results in

• 🌏 API Server running at http://localhost:8080

• ⛁ MongoDB running at mongodb://localhost:27017/db

Packaging and Deployment

1. Build and run without Docker

$ go build 

2. Run Tests

$ cd tests
$ go test

3. Run with docker

$ docker build -t api-server .
$ docker run -t -i -p 8080:8080 api-server

4. Run with docker-compose

$ docker-compose up
