Getting Started

Prerequisites

• Docker Desktop v4.11.1 (84025) - (Download)

Running the application in Docker

1. Create your .env file with the required values:

See Auth0 Setup Section to set-up your Auth0 account properly and retrieve these values.

2. Start the application with:

yarn up

3. Run the initial migrations

This command can be used to migrate the database at anytime.

yarn migrate

Notes:

• Restarting the application will not run migrations automatically, you must run them manually.
• Migrations will not auto-run on hot reload.

4. Viewing the dev site

Once everything is running you can visit the application at:

• App: http://localhost:3000
• Studio: http://localhost:5555

5. Viewing logs

You can view logs with the following commands:

App logs only:

yarn logs app

app can be replaced with any of the other Docker container name.

All logs:

yarn logs

Useful Info

Connecting to Postgres with your favorite Postgres Client

Only useful if you don't want to use the already provided Prisma Studio container.
Some of these values can be overridden by a .env environment variable.

Field	Value	Overridable Via
Host	localhost
Port	5432	POSTGRES_PORT
Database	myapp	POSTGRES_DATABASE
Username	admin	POSTGRES_USERNAME
Password	admin	POSTGRES_PASSWORD

Other useful commands

Omitting container_name will run the command on all containers.

yarn restart {container_name}

yarn stop {container_name}

Docker Containers

• app - NextJS Application
  • Port 3000 - Application
  • Port 9229 - Debugger
• studio - Prisma Studio
  • Port 5555 - Studio
• postgres - PostgreSQL DB
  • Port 5432 - DB

Notable Packages Pre-installed

@heroicons/react (NPM) (Github) (Docs)

This is the package to use HeroIcons with React

classnames (NPM) (Github)

This is used to manage the state of class names in React components.

Example use:

import classnames from 'classnames'

const MyComponent: FCC<Props> = (props) => {
  const classList = classnames([
    'flex', 'justify-center', 'items-center', 'appearance-none',
    'select-none', 'w-full', 'p-2', 'tap-highlight-none',
    // Text
    'font-medium', 'text-black',
    // Focus
    'focus:outline-none', 'focus:ring',
    // Ring
    'ring',
    // Disabled
    'disabled:bg-gray-300', 'disabled:ring-gray-300', 'disabled:cursor-not-allowed', 'disabled:text-gray-400',
    // Scale on click
    'scale-on-click',
    'rounded-sm',
  ], {
    'h-10': !props.small,
    'h-8 md:h-6': props.small,
  }, {
    // Primary
    'bg-amber-300': props.color === 'primary',
    'ring-amber-300': props.color === 'primary',
    'hover:bg-amber-400': props.color === 'primary',
    'hover:ring-amber-400': props.color === 'primary',
  }, props.className)
  
  return (
    <button className={classList}>My Button</button>
  )
}

MyComponent.defaultProps = {
  small: false,
  color: 'primary',
}

type Props = {
  small?: boolean
  color?: 'primary' | 'secondary'
}

export default MyComponent

formik (NPM) (Github) (Docs)

This is used to manage the state of input forms in the application. Formik uses joi.

joi (NPM) (Github) (Docs)

This is used as validation for formik.

zod (NPM) (Github) (Docs)

This is used as validation for tRPC. Yea... two validation libraries... Will replace joi when we find a good forms library that supports zod natively.

usehooks-ts (NPM) (Github) (Docs)

A library of useful React hooks.

@headlessui/react (NPM) (Github) (Docs)

A library of useful React components.
