2. Configuration

Configuration

Some parameters for the server can be edited to customize the limits set by default.

There are 4 ways you can change these to your liking:

• Modify the default values before building the project in the config file
• Feed environment variables to the start script
  • PORT=5000 PASSWORD=admin123 npm start
• Use dotenv
  • Create a .env file at the root of the project
  • Specify your variables (PORT=5000) separated by new lines. (See How to read environment variables from NodeJS)
• If you're using Heroku, update the config vars from the "settings" tab of your app.

Environment	Type	Description	Default
PORT	number	Port number of the server	3000
PASSWORD	string	Password that should be used in 'Authorization' header	letmein
USE_PASSWORD	boolean	Whether or not to authenticate routes with a password	true
MAX_FILE_UPLOAD_COUNT	number	Maximum amount of files that can be uploaded at once	10
MAX_FILE_UPLOAD_SIZE	number	Maximum file size of the individual file uploaded (total would be MAX_FILE_UPLOAD_SIZE * MAX_FILE_UPLOAD_COUNT)	100MB
MAX_MERGER_FILE_COUNT	number	Maximum total files a merger can hold	10
MAX_MERGER_FILE_SIZE	number	Maximum total size a merger can hold	100MB
MAX_MERGERS	number	Maximum amount of total mergers that can exist at the same time	5
CLEANUP_MERGERS_DELAY	number	Time (ms) after which a merge is cleaned up. When cleaning up a merge, all files associated with it are deleted.	45s
CLEAN_AFTER_MERGE	boolean	Whether or not to clean up the merger immediately after sending a merged video, instead of waiting for CLEANUP_MERGERS_DELAY.	true
DB_ADAPTER	fs | redis | mongo	Which database adapter to use for storing data. fs - Uses a JSON file system to store data. redis - Uses a Redis database to store data. (Requires Redis to be installed) mongo - Uses a MongoDB database to store data. (Requires MongoDB to be installed) Note: if you use fs with Heroku, keep in mind Heroku deletes the files periodically. However, this shouldn't be a problem, since the app does not keep data for long.	fs
REDIS_URL	string	The Redis URL to use when DB_ADAPTER is redis	redis://localhost:6379
MONGO_URL	string	The MongoDB URL to use when DB_ADAPTER is mongo	mongodb://localhost:27017
REQUEST_LOGGING	boolean	Enable request logging	true
MERGER_LOGGING	boolean	Enable merger logging	true
DB_LOGGING	boolean	Enable database operations logging	true
CLUSTER_MODE	boolean	Enables PM2 cluster mode, which starts multiple instances with load balancing. Note: Custer mode will not be enabled if DB_ADAPTER is set to fs.	true
