Configuration

This is a list of the environment variables you can set to make things work as you might expect.

Shared Config

These configuration options are shared between the server and client.

  • HTTPS (default 'true') - set this to 'false' if you are not running on https. Mostly affects cookie options.
  • HTTPS_PROXY (default 'true') - this should be set to 'true' if you are using SSL termination (like from an ELB), which helps SSL cookies function.
  • SWITCHAROO_DEBUG (default 'true') - log errors to console.
  • MINIFY_ASSETS (default 'true') - use minified assets.
  • LIVERELOAD (default 'true') - enable livereload (for use with npm run watch).
  • STATIC_BASE (default '') - set the base url for static assets. Useufl if you upload static assets to an S3 bucket.
  • ORIGIN (default 'http://localhost:4444') - your server url. Used when fully qualified urls are necessary.
  • PORT (default 4444) - the port you want to run on. (Make sure to update ORIGIN too.)
  • NODE_ENV (default 'development') - sets node logging levels.
  • NON_AUTH_API_ORIGIN (default 'https://ssl.reddit.com') - the url to hit for unauthenticated requests.
  • AUTH_API_ORIGIN (default 'https://oauth.reddit.com') - the url to hit for requests that include oauth tokens.
  • REDDIT (default 'https://www.reddit.com') - the base url for reddit pages.
  • LOGIN_PATH (default '/oauth2/login') - use either the oauth redirect, or if you are a trusted application, set to '/login' to use password authentication.
  • GOOGLE_ANALYTICS_ID (default null) - if you want to use GA, add your id.
  • GOOGLE_TAG_MANAGER_ID (default null) - if you want to use GTM, add your container id.
  • ADBLOCK_TEST_CLASSNAME (default 'ad adsense-ad googad gemini-ad openx') - class used to test for the presence of an adblocker.
  • ADS_PATH (default 'https://www.reddit.com/api/request_promo.json') - the url to hit to load ads. Set to empty if you do not wish to load ads.
  • TRACKER_KEY (default null) - the key to use to send events to the event collector
  • TRACKER_ENDPOINT (default null) - the url to send events to the event collector
  • TRACKER_CLIENT_NAME (default null) - the name of the client to send to the event collector

Secret Server Config

These options are never shared with the client.

  • OAUTH_CLIENT_ID - your oauth client id.
  • OAUTH_SECRET - take a wild guess.
  • SECRET_OAUTH_CLIENT_ID and SECRET_OAUTH_SECRET - if you have a privileged client that can use the password authentication flow (unlikely unless you host your own reddit instance), this is what you use for that flow.
  • SERVER_SIGNED_COOKIE_KEY - you should set this to something long and complicated, so you can protect your cookies.
  • PROCESSES (defaults to number of cpu cores) - how many node processes to start and run with node clustering.
  • API_HEADERS - semicolon-delimited list of colon-delimited key:value pairs of headers the server should send to the api. For example: ratelimiting:off;moose:majestic
  • API_PASS_THROUGH_HEADERS - semicolon-delimited whitelist of headers (lowercase) that the server should send to the api during server rendering. For example: accept-language;other-thing. (user-agent is sent automatically.)
  • STATS_URL - a url that tracking data should be sent to (such as page load times.) reddit uses a metron instance
  • MEDIA_DOMAIN – a cookieless domain used for non-trusted code. to send page load timings to statsd, for instance.
  • ACTION_NAME_SECRET - a secret key used to sign data send to the stats server, as set above.
  • EXPERIMENTS - semicolon-delimited list of name:percentage experiments that should be enabled (see server.jsx for examples of running experiments.)
