Fic.AI signals server

The backend component that provides the API for accessing and modifying a user's contribution to the Fic.AI database in the form of "signals".

Each signal indicates approval or disapproval of a tag (identified by name) being applied to a story (identified by its canonical URL).

Running the server

The server expects the following environment variables to be set:

• FICAI_LISTEN is the socket address on which the API will be available. Example: 127.0.0.1:8080
• FICAI_DB_HOST is the host on which the DB server can be accessed. Example: localhost
• FICAI_DB_PORT is the port on which the DB server is listening for connections. Example: 5432
• FICAI_DB_USERNAME is the user name for DB access
• FICAI_DB_PASSWORD is the password for the abovementioned user
• FICAI_DB_DATABASE is the name of the database in which the server's tables must be present
• FICAI_PWD_PEPPER is the pepper value for password hashes. Must be specified as unpadded Base64 with standard alphabet as defined in RFC-4648. Recommended minimum length (before Base64 encoding) is 32 bytes, see Kitten. You can generate a suitable value by running openssl rand -base64 32 and stripping any = characters from the end of its output. Read more about peppering passwords at OWASP-PSCS.
• FICAI_DOMAIN is the domain (no URL schema or port!) on which the service will be accessible. Used for the session ID cookie.
• FICAI_BETA_KEY is the extra key a user must give on registration during the inital beta period.
