PNGR Stack

Dockerized (postgres + nginx + golang + react) starter kit

Only implements basic user signup, session management, and a toy post type to demonstrate basic CRUD. PNGR is not a CMS.

Features

alpine

Requirements

Install docker && docker-compose

Quick Start

sudo docker-compose up
Visit https://localhost ( note https )
Approve the self-signed cert
Make changes to either golang or react code, and enjoy hot-reload goodness!

Rebuilding your dev environment

Maybe your postgres went sideways from a wonky migration and you don't want to muck with fixing it.

sudo docker-compose down -v && sudo docker-compose up --build --force-recreate

Deploying to Production

Warning: Run in production at your own risk - this code is not security hardened!

Everyone's production deployment will look different, but some thoughts:

P Consider running an actual postgres instance. Running a production database in docker makes me sweat.
N Look at nginx/nginx.prod.conf for ideas on what a production configuration might look like.
G Use golang/Dockerfile.prod
R Use react/Dockerfile.prod
- e.g. From project root you can run sudo docker build -t react-prod -f react/Dockerfile.prod react
- Test it out with sudo docker run --net=host react-prod then hit http://localhost in your browser

Postgres

Some tips for working with your postgres docker instance

Creating and running migrations

Migrations are run using go-migrate .

I put together little bash scripts to help you get stuff done.

sudo postgres/new-migration.sh my_migration_name
sudo postgres/run-migrations.sh

You can do more advanced migrate commands

Opening a psql client

sudo docker-compose exec postgres psql -U postgres Remember to use \q to exit.

Nginx

Nginx is simply used to route requests to the front-end and back-end based on path. It also terminates SSL so that we don't have to deal with certs in our app layer.

Golang

Almost-vanilla golang api:

Makes use of go modules for dependencies
jwt-gp for JSON Web Tokens
sqlx for better postgres interface

React

The basic building blocks of the front-end are:

Create React App (unejected!)
React Router
Unstated for state management
Semantic UI React for component library
