@overleaf/settings

A small module to allow global config settings to be set for all services within the Overleaf architecture.

Settings file location

You can specify a custom location for the settings file by setting the OVERLEAF_CONFIG environment variable. E.g.

$ export OVERLEAF_CONFIG=/home/james/config/settings.development.js

Otherwise, the settings will be loaded from config/settings.NODE_ENV.js, where NODE_ENV is another environment variable, or defaults to development.

The config directory is first looked for in the current directory, and then relative to the settings module directory.
