passport-saml-cache-postgres

A PostgreSQL-backed cache provider for @node-saml/passport-saml.

Usage

Create a passport_saml_cache table in your database. The default schema can be found in schema.sql.

import { Strategy as SamlStrategy } from '@node-saml/passport-saml'
import postgresCacheProvider from 'passport-saml-cache-postgres'

passport.use(new SamlStrategy({
    ... other passport-saml options,
    cacheProvider: postgresCacheProvider(pool) // A pg.Pool object
}))

Configuration

The postgresCacheProvider function accepts an optional second argument. The default options are as follows:

postgresCacheProvider(pool, {
  // The maximum age of a cache entry in milliseconds. Entries older than this are deleted automatically.
  // A scheduled job deletes old cache entries every `ttlMillis` milliseconds.
  ttlMillis: 1000 * 60 * 60, // 1 hour,
  // A logger to use. By default, messages are logged to console.
  // The logger should support at least `logger.info()` and `logger.error()` methods.
  logger: console
})

Closing the cache

The cache can be closed by calling the .close()-method. This stops the scheduled job that periodically clears stale cache entries.
