Heroku Apps Review

class: center, middle

# What is your development process?

---

## Our Pipeline
--

* development - <span class="small">http://localhost:3000/</span>
--

* test
--

* staging - <span class="small">https://tradegecko-staging.herokuapp.com/</span> - We have staging?
--

* production - <span class="small">https://go.tradegecko.com/</span>

---

## What are we missing?
--

- Ability to QA working code before merging into `develop`.
--

- Reviewer must pull the repo / start the app ( or apps, we have 4+ essential apps )
--

- Ability to see / showcase design changes before merging.
--

- Author must provide screenshots / GIFs (pronounced “jif”)
--

- Only people with access to Github are able to QA the changes.
--

## New Pipeline

* development
* test
* <span class="red">**review**</span>
* staging
* production

# Heroku Apps Review

---

---

---

---

---

---

# How the new app is deployed

1. Configure environment
2. Build app
3. Run scripts & scale dynos
4. Deploy to Heroku

---

# 1. Configure environment

* `app.json`
--

* Create app
--

* Setup environment vars (`"env"`)
--

* Attach resources (DB, Redis..) (`"addons"`)

---

## `app.json`

```json
{
  "name": "TradeGecko",
  "description": "Powerful inventory management software to help you take complete control of your business.",
  "addons": [
    "heroku-postgresql:hobby-dev",
    "heroku-redis:hobby-dev",
    "papertrail:choklad",
    "mailtrap:free"
  ],
  "env": {
    "API_TOKEN_HEROKU":  { "required": true,
                           "description": "Used to talk to heroku's API" },
    "RAILS_ENV":         { "value": "staging" },
    "AWS_ACCESS_KEY_ID": { "required": true }
  },
  "scripts": { "postdeploy": "bin/heroku-review-postdeploy" },

"formation": {
    "web":    { "quantity": 1, "size": "free" },
    "worker": { "quantity": 1, "size": "free" }
  }
}
```
---

# 2. Build app

Just like `heroku push origin master`

1. User buildpack to decide deploy strategy
2. Copy code from repo
3. Install gems
4. build assets
5. Deploy
---

# 3. Run scripts & scale dynos

## `bin/heroku-review-postdeploy`

This runs only once per app creation.

Will not run if:
- pushing a new commit
- force pushing

You can re-run the script only if you delete the app / or run script manually (Don't do this).

What it does:

- `bin/rails db:schema:load`
- `bin/rails db:seed`
- setup [mailtrap](https://mailtrap.io/)

---

# 4. Deploy to Heroku

# Doesn't really do anything. The app is already deployed.

---

## When is it deployed?
--

# Everytime you push to that branch
--

1. First deploy is slow, others are fast.
--

2. App is destroyed after `X` days of no use.
---

## How do I access the app?
--

1. `https://tradegecko-staging-pr-#{pr_num}.herokuapp.com`
--

2. Link is in the PR

## What Jobs are run?
--

# EVERYTHING
--

<span class="small">(I think)</span>
--

App jobs will go through `worker` dyno, which runs the `default` queue

`config/initializers/sidekiq.rb:61`
```ruby
if Rails.env.staging?
  class SidekiqDefaultToWorker
    def call(_worker_class, job, _queue, _redis_pool)
      job['queue'] = 'default'
      yield
    end
  end
end

Sidekiq.configure_client do |config|
  config.client_middleware do |chain|
    chain.add SidekiqDefaultToWorker if Rails.env.staging?
  end
end
```

## Dude, where's my mail?

# Mailtrap
--

1. Open app management screen in heroku.
2. Click on "Mailtrap"
2. `heroku addons:open mailtrap -a tradegecko-staging-pr-#{pr_num}`

the end
--
... ?
--

# No

---

# What doesn't work
--

- OAuth Login
- Anything outside of the app.
- All other TG services: (B2B, Geckopay.., etc.)
- Integrations.. (You can add new integrations yourself)
- mailtrap is only accessible to users with Heroku access
- missing realistic seed data
- toggle management

---

# HALP!

- Add your ENV vars to `app.json`
- Add proper seed data.
- Add features toggles to UI / seed file
