## For prisma
Notes: Uses docker

1. Install prisma
`npm install prisma`

2. Create service directory (The name will be passed by command line argument)
`mkdir hello-world`
`cd hello-world`

3. Use templates of docker-compose
TODO: Change to be able to use PostgreSQL or MongoDB.

`cp ../docker-compose.yml .`

4. Launch
`docker-compose up -d`

5. Configure prisma API
`npx prisma init --endpoint http://localhost:4466`

6. Deploy prisma datamodel
`prisma deploy`

7. Generate prisma client

Append the following lines to the end of your `prisma.yml`

```
generate:
  - generator: javascript-client
    output: ./generated/prisma-client/
```

8. Generate

`prisma generate`

9 Prepare Node Application

`touch index.js`
`npm init -y`
`npm install --save prisma-client-lib`

I think below is not appropriate
```index.js
const { prisma } = require('./generated/prisma-client')

// A `main` function so that we can use async/await
async function main() {
  // Create a new user called `Alice`
  const newUser = await prisma.createUser({ name: 'Alice' })
  console.log(`Created new user: ${newUser.name} (ID: ${newUser.id})`)

  // Read all users from the database and print them to the console
  const allUsers = await prisma.users()
  console.log(allUsers)
}

main().catch(e => console.error(e))
```

## For Expo

1. Install expo

`npm install expo-cli`

2. Init Expo (The name will be passed by command line argument)

`npx expo init my-new-project`
`cd my-new-project`

3. Copy template js files

`cp ../index.js .`

4. Start Expo

`npx expo start`
