Не нашел в документации монго ответа. Перезаписывает ли  db.collection.update()  документ полностью? И если да/нет то есть ли где про это почитать можно?
В самих документах есть абзац:
Field Order
For write operations, MongoDB preserves the order of the document fields...
Т.е. с документом что-то делается раз очередность полей не меняется/меняется

> В хранилище bson обновится целиком. BSON не поддерживает in-place обновлений, так как список и типы полей заранее неизвестны, как следствие невозможно определить смещение, где расположено значение

# pravosleva-blog [2021-03-24]

## 🧨 Life demo
**http://code-samples.space**

## 🏗 Infrastructure
- NGINX
- Node.js
- PM2
- MongoDB 4.2.11

## 🔥 Quick start

### Step 1: Clone & install
```bash
git clone https://github.com/pravosleva/next-mongodb.git
cd next-mongodb && yarn
```

### Step 2.1: Development
`ecosystem.dev.config.js`
```js
module.exports = {
  apps: [
    {
      name: 'notes-2020-next-mongoose-dev',
      cwd: __dirname + '/.',
      script: 'yarn',
      args: 'dev',
      interpreter: 'none',
      env: {
        MONGO_URI: <YOUR_DEV_MONGO_URI>,
        JWT_SECRET: <YOUR_DEV_JWT_SECRET>,
        EXPRESS_JWT_MAXAGE_IN_DAYS: 3,
        EXPRESS_IS_USER_SIGNUP_ENABLED: 1,
      },
    },
  ],
}
```
`.env.dev`
```bash
MONGO_URI=<YOUR_DEV_MONGO_URI>
NEXT_APP_API_ENDPOINT=http://localhost:9000/api
NEXT_APP_SOCKET_API_ENDPOINT=http://localhost:9000
NEXT_APP_EXPRESS_API_ENDPOINT=http://localhost:9000/e-api
NEXT_APP_COOKIE_MAXAGE_IN_DAYS=2
```
_Run on http://localhost:9000:_
```bash
pm2 start ecosystem.dev.config.js
```

### Step 2.2: Production
`ecosystem.prod.config.js`
```js
module.exports = {
  apps: [
    {
      name: 'notes-2020-next-mongoose-dev',
      cwd: __dirname + '/.',
      script: 'yarn',
      args: 'start:prod',
      interpreter: 'none',
      env: {
        MONGO_URI: <YOUR_PROD_MONGO_URI>,
        JWT_SECRET: <YOUR_PROD_JWT_SECRET>,
        EXPRESS_JWT_MAXAGE_IN_DAYS: 3,
        EXPRESS_IS_USER_SIGNUP_ENABLED: 0,
      },
    },
  ],
}
```
`.env.prod`
```bash
MONGO_URI=<YOUR_PROD_MONGO_URI>
NEXT_APP_API_ENDPOINT=<YOUR_HOST>/api
NEXT_APP_SOCKET_API_ENDPOINT=<YOUR_HOST>
NEXT_APP_EXPRESS_API_ENDPOINT=<YOUR_HOST>/e-api
NEXT_APP_COOKIE_MAXAGE_IN_DAYS=2
```
_Run on tcp 9000 (hardcoded to `package.json`):_
```bash
pm2 start ecosystem.prod.config.js
```
