## Faster inner development loop

1. Install an alternative linker for the current OS (see `Cargo.toml`)

2. `cargo install cargo-watch`

3. `cargo watch -x check -x test -x run`

## De-occupy the port

```shell

lsof -t -i tcp:8000 | xargs kill -9

```

## Expand macros

1. `cargo install cargo-expand`

2. `rustup toolchain install nightly --allow-downgrade`

3. `cargo +nightly expand`

## Remove unused dependencies

1. `cargo install cargo-udeps`

2. `cargo +nightly udeps`

## Docker

```sh

# Update SQLx schema for offline builds

cargo sqlx prepare -- --lib

# Build and run image

docker build --tag zero2prod --file Dockerfile .

docker run -p 8000:8000 --network=host zero2prod

```

## Digital Ocean

```sh

# Create app

doctl apps create --spec spec.yaml

# Get app ID and URL

app_id=$(doctl apps list | awk '/zero2prod/ {print $1}')

app_url=$(doctl apps list | awk '/zero2prod/ {print $3}')

# Update app

doctl apps update $app_id --spec=spec.yaml

# Migrate database

DATABASE_URL=$database_url sqlx migrate run

# Health check

curl -v $app_url/health_check

# Post

curl -v $app_url/subscriptions -d 'name=Le%20Guin&email=ursula%40leguin.com'

# Delete

doctl app delete --force $app_id

```
