Hypothesis Direct-Link Bouncer Service

Configuration

You can set various environment variables to configure bouncer before running it in production or development:

CHROME_EXTENSION_ID

The ID of the Hypothesis Chrome extension that bouncer will communicate with (default: the ID of the official Hypothesis Chrome extension)

DEBUG

If DEBUG is set (to any value) then tracebacks will be printed to the terminal for any unexpected Python exceptions. If there is no DEBUG variable set in the environment then unexpected Python exceptions will be reported to Sentry and a generic error page shown to the user.

ELASTICSEARCH_HOST

The hostname of the Elasticsearch server that bouncer will read annotations from (default: localhost)

ELASTICSEARCH_INDEX

The name of the Elasticsearch index that bouncer will read annotations from (default: hypothesis)

ELASTICSEARCH_PORT

The port of the Elasticsearch server that bouncer will read annotations from (default: 9200)

HYPOTHESIS_URL

The URL of the Hypothesis front page that requests to bouncer's front page will be redirected to (default: https://hypothes.is)

SENTRY_DSN

The DSN (Data Source Name) that bouncer will use to report crashes to Sentry

STATSD_HOST

The host of the statsd server that bouncer will report stats to (default: localhost)

STATSD_PORT

The port of the statsd server that bouncer will report stats to (default: 8125)

STATSD_PREFIX

A string prefix that bouncer will prepend to all metric paths reported to statsd (default: none). We recommend export STATSD_PREFIX=bouncer so that all bouncer's metrics will start with bouncer.

VIA_BASE_URL

The base URL of the Via service that bouncer will redirect users to if they don't have the Hypothesis Chrome extension installed (default: https://via.hypothes.is)
