Boilerplate for creating web applications in Go (golang)

Alloy

Alloy is a starter template for creating web applications using Go programming language. It does not aim to be a web framework but is instead a collection of useful libraries and packages that acts a sensible starting point.

Recently, I decided to build my latest side project using Go. I started off with just the standard library and then gradually added a few recommended packages for performing common tasks like database calls (sqlx), migrations (pressly/goose) and sending emails (gomail). This boilerplate has been extracted from that side project.

Alloy uses Webpack for managing front-end assets (Javascript and CSS), so you need to have Node.js and NPM installed in order to use that. This boilerplate also includes a separate 'admin panel' which acts as a CMS for adding pages, managing users etc.

<shameless plug> GrowthMetrics is a nifty little tool to measure your business's customer satisfaction using a metric called NPS (Net Promoter Score). You can signup for the early access (and early bird discount) here - https://www.growthmetrics.io/beta.

** NOTE: ** Currently this uses Postgres as the database, so you would need postgres to be running before you start the application. In future releases, I will be adding support for other databases.

Available commands

Usage:
  alloy [command]

Available Commands:
  db          Manage the app's database (create migration, migrate up/down/redo).
  dev         Start the development server (along with webpack watch)
  gen-key     Generate a random key to use with securecookies
  help        Help about any command
  new-admin   Manage the admin user(s)
  server      Start the server
  version     Print the version number of alloy

Installation and usage

1. Clone the repository

git clone https://github.com/olliecoleman/alloy
cd alloy

2. Install the dependencies

glide install
npm install

3. Create the following environment variables.

PORT=1212
ENVIRONMENT=development (change to 'production' in the production environment)
HOST=localhost
DATABASE_URL=XXX (replace)
TEST_DATABASE_URL=XXX (replace)
MIGRATIONS_DIR=app/migrations
CSRF_KEY=XXX (replace with 32 character string (use the gen-key command))
HASH_KEY=XXX (replace with 64 character string (use the gen-key command))
BLOCK_KEY=XXX (replace with 32 character string (use the gen-key command))
SMTP_HOST=127.0.0.1
SMTP_PORT=1025
SMTP_USERNAME=__REPLACE__
SMTP_PASSWORD=__REPLACE__
MAILER_FROM=XXX (e.g: [email protected])
MAILER_HOST=http://localhost:1212
ASSET_URL=http://localhost:1212 (if you are using a CDN in production, this can be set to that URL)

3. Start the development server

go install
alloy dev

Now you can open your browser and navigate to http://localhost:1212 to see it in action. Any changes you make to the .go files will be automatically picked up and the app will be re-compiled.
