Configuration

All configuration is done through environment variables.

Not all of these are necessary to run the code. The most important ones are:

DIGITALOCEAN_POSTGRES pointing to the working Postgres database
NEXT_PUBLIC_SITE_URL for the frontend to work properly

There's also a template configuration file in ../env.example.

Database endpoints

DIGITALOCEAN_POSTGRES, of the form postgres://username:password@domain.com:port/configvars. (Disregard DIGITALOCEAN_ prefix, you can use any endpoint you like).
DIGITALOCEAN_POSTGRES_PUBLIC
MONGODB_URL, a string in the format "mongodb+srv://<username>:<password>@<mongodburl>/?retryWrites=true&w=majority&useNewUrlParser=true&useUnifiedTopology=true" (No longer really needed, superseded by Postgres).
ALGOLIA_MASTER_API_KEY, a string of 32 hexidecimal characters, like 19b6c2234e50c98d30668659a39e3127 (not an actual key).

Platform cookies and keys

Most of these are just session cookies, necessary to query INFER (previously CSET Foretell), Good Judgment Open and Hypermind (Hypermind is now deprecated). You can get these cookies by creating an account in said platforms and then making and inspecting a request (e.g., by making a prediction, or browsing questions).

Note that not all of these cookies are needed to use all parts of the source code. For instance, to download Polymarket data, one could just interface with the Polymarket code. In particular, the code in this repository contains code to with the mongo database using read permissions, which are freely available.

GOODJUDGEMENTOPENCOOKIE
INFER_COOKIE
CSETFORETELL_COOKIE, deprecated, superseded by INFER_COOKIE.
HYPERMINDCOOKIE
GOOGLE_API_KEY, necessary to fetch Peter Wildeford's predictions.
SECRET_BETFAIR_ENDPOINT

Configuration flags

POSTGRES_NO_SSL, can be set to a non-empty value to disable SSL; can be useful for local development.
DEBUG_MODE, usually off, which controls log verbosity.

Others

NEXT_PUBLIC_SITE_URL, e.g., http://localhost:3000 if you're running a local instance
REBUIDNETLIFYHOOKURL
BACKUP_PROXY_IP
BACKUP_PROXY_PORT

Old doc

Others interface with services, e.g., to access the MongoDB database I'm using to save data and history, or to renew the algolia database. You can get these keys by creating an account with those services.

Overall, the services which we use are:

Algolia for search
Netlify for frontend deployment
Heroku and DigitalOcean for backend deployment
Postgres and Mongo for databases
