## Run as a Docker instance
### Configure application
Use the following environment variables to configure the application.

| Option      | Default value | Description | Server | Client |
| ----------- | ------------- | ----------- | :------: | :------: |
| `PORT` | `5000` | The port used by the started application |  ✅  | ✅ |
| `SERVE_CLIENT` | `true` | Should the server serve client (Fully local application) |  ✅  | ⬜️ |
| `IMAGES_PATH` | `./images` | The directory where the images are stored (absolute path if changed ⚠️) |  ✅  | ⬜️ |
| `MONGO_URI` | `mongodb://localhost/webexpe` | MongoDB database connection URI |  ✅  | ⬜️ |

Configure more deeply the way the app works by modifying *[config.js](config.js)*.

| Option      | Default value | Description |
| ----------- | ------------- | ----------- |
| `apiPrefix` | `/api` | The url prefix for the API |
| `imageServedUrl` | `/api/images` | The url prefix from where the images are served |
| `serverPort` | `5000` | The port used by the server |
| `mongoDatabaseURI` | `mongodb://localhost/webexpe` | MongoDB database connection URI |
| `imagesPath` | `./images` | The directory where the images are stored |
| `serveClient` | `true` | Should the server serve client files from the `/dist` directory |
| `fileNameConvention` | `/^(.*)?_([0-9]{2,})\.(.*)$/` | File name convention for images |
| `extractsDirName` | `extracts` | Name of the directory containing extracts |
| `sceneFileNameBlackList` | `['config', 'seuilExpe', 'extracts']` | Files to ignore in scenes |
| `deleteExtractsCronTime` | `0 3 * * *` (every day at 03:00 AM) | Cron time for extracts deletion |
| `logger` | Logs : `logs/server.combined.log` Errors : `logs/server.error.log` | Default application logger |
| `wsLogger` | Logs : `logs/ws.log` Errors : `logs/ws.error.log` | WebSocket logger configuration |
| `dbLogger` | Logs : `logs/db.log` Errors : `logs/db.error.log` | Database logger configuration |

### Configure experiments
If you want to use the default experiments configurations, you can skip this part, the Dockerfile does it for you.

You can modify the configuration for each mixins, experiments or scene. To do so, you first need to initialize experiment configurations first.
```sh
cp -r experimentConfig.default experimentConfig
```
You can modify the configuration for each mixins, experiments or scene by modifying files in the newly created *`./experimentConfig`* directory.
You configuration will be copied in the Docker instance.

### Run server + client
Linux
```sh
PORT=8080 SERVE_CLIENT=true IMAGE_PATH=/var/images docker-compose up
```
Windows
```bat
SET PORT=8080
SET SERVE_CLIENT=true
SET IMAGE_PATH=C:\my\images
docker-compose up
```

### Run server only
Linux
```sh
SERVE_CLIENT=false docker-compose up
```
Windows
```bat
SET SERVE_CLIENT=false
docker-compose up
```

### Run client only
```sh
docker-compose -f docker-compose.frontapp_only.yml up
```

### Notice
#### New version Docker build
When using a new version of the project, you need to re-build the application with Docker.
```sh
# Server / Server + client versions
docker-compose build

# Client only version
docker-compose -f docker-compose.frontapp_only.yml build
```

#### Docker instance on a Windows host
As of now, Windows hosts are not supported due to MongoDB volumes not being mappable to this system.

## Run on the file system
### Project setup
Install project's dependencies.
```
yarn install
```

If this is a production build, set the `NODE_ENV` environment variable to `production` to enhance performance.

Linux
```sh
export NODE_ENV=production
```
Windows
```bat
SET NODE_ENV=production
```

### API
#### Run the server
```sh
yarn run server:start
```
If you specifically want to not start the extracts remover service (extracts are automatically deleted everyday), use the following.
```sh
server:start:no-delete-extracts
```

#### Automatically fix the API code syntax with ESLint
```sh
yarn run server:lint
```


### Client
To use the client, you need to initialize experiment configurations first.
```sh
cp -r experimentConfig.default experimentConfig
```
You can modify the configuration for each mixins, experiments or scene by modifying files in the newly created *`./experimentConfig`* directory.


#### Compile and minify for production
Files will be built to the `dist/` directory.
```sh
yarn run app:build
```

#### Run a hot-reload server for client development
```sh
yarn run app:dev
```


#### Automatically fix the client code syntax with ESLint
```sh
yarn run app:lint
```

## Automated deployment
The app can be automatically deployed when a push event is sent to the master branch using Gogs. Open a port to the web and start *[webhook_deploy_gogs.js](webhook_deploy_gogs.js)*.
```sh
WEBHOOK_SECRET=your_webhook_secret WEBHOOK_PORT=5000 SERVE_CLIENT=true PORT=8080 node webhook_deploy_gogs.js
```
You can pass any parameters to the script, they will be passed to the Docker instance. The following are required.

| Option      | Description |
| ----------- | ----------- |
| `WEBHOOK_SECRET` | The secret set on Gogs to verify the identity |
| `WEBHOOK_PORT` | The port the script is listening to |

## Running tests
The `docker-compose` script will automatically run tests. Use the following command to run them by hand.
```sh
yarn test
```

## Documentation
The `docker-compose` script will automatically build the documentation. Use the following command to build it by hand.
```sh
yarn doc
```
The documentation is generated to the `doc/` directory. If you started the server, the documentation is served at `/doc/`.
