Configuration

Configuration

Doorman uses a JSON configuration file to define your firewall rules. The configuration is validated using JSON Schema and provides full TypeScript support.

Schema URL

Add the schema reference to your config file for editor autocompletion and validation:

{
  "$schema": "https://doorman.griffen.codes/schema.json"
}

Root Properties

Property	Type	Required	Description
$schema	string	No	JSON Schema URL for validation
provider	string	No	Default provider ("vercel", "cloudflare", or "fastly")
projectId	string	Vercel Only	Vercel project ID
teamId	string	Vercel Only	Vercel team ID (optional)
providers	object	Multi-Provider	Provider-specific configurations
rules	array	Yes	Array of firewall rules
ips	array	No	Array of IP blocking rules
version	number	No	Configuration version

Rules

Rule Structure

{
  "id": "rule_block_bots",
  "name": "Block Bad Bots",
  "description": "Block malicious bots and crawlers",
  "active": true,
  "conditionGroup": [
    {
      "conditions": [
        {
          "type": "user_agent",
          "op": "sub",
          "value": "bot",
          "neg": false
        }
      ]
    }
  ],
  "action": {
    "mitigate": {
      "action": "deny"
    }
  }
}

Rule Properties

Property	Type	Required	Description
id	string	No	Unique rule identifier
name	string	Yes	Human-readable rule name
description	string	No	Rule description
active	boolean	Yes	Whether rule is enabled
conditionGroup	array	Yes	Array of condition groups (OR logic)
action	object	Yes	Action to take when rule matches

Condition Groups

Condition groups use OR logic between groups and AND logic within groups:

{
  "conditionGroup": [
    {
      "conditions": [
        { "type": "path", "op": "pre", "value": "/admin" },
        { "type": "method", "op": "eq", "value": "POST" }
      ]
    },
    {
      "conditions": [
        { "type": "ip_address", "op": "eq", "value": "192.168.1.1" }
      ]
    }
  ]
}

This translates to: (path starts with "/admin" AND method equals "POST") OR (IP equals "192.168.1.1")

Condition Types

Type	Description	Vercel	Cloudflare	Fastly
host	Hostname	✅	✅	✅
path	URL path	✅	✅	✅
method	HTTP method	✅	✅	✅
header	HTTP header	✅	✅	✅ Requires a key
query	Query parameter	✅	✅	✅ Requires a key
cookie	Cookie value	✅	✅	✅ Requires a key
user_agent	User agent string	✅	✅	✅
ip_address	IP address	✅	✅	✅
geo_country	Country code	✅	✅	✅
geo_continent	Continent code	✅	✅	❌
geo_city	City name	✅	✅	❌
protocol	Protocol	✅	✅	❌
scheme	URL scheme	✅	✅	✅

On Fastly, header/query/cookie conditions translate to a multival condition block rather than a plain single condition — see Fastly Setup.

eq	Equals	✅	✅	✅
pre	Starts with	✅	✅	⚠️ Approximated (wildcard like, not a true prefix match)

sub	Contains	✅	✅	✅
inc	Is any of (array)	✅	✅	✅
re	Regex match	✅	⚠️ Enterprise	✅
ex	Exists	✅	✅	⚠️ Only on header/query/cookie multival conditions
nex	Does not exist	✅	✅	⚠️ Only on header/query/cookie multival conditions

bypass	Skip other rules	✅	✅	⚠️ No equivalent — maps to allow
rate_limit	Rate limiting	✅	✅	✅ Requires a pre-existing signal — see Fastly Setup

        "window": "60s"
      }
    }
  }
}

    "mitigate": {
      "action": "redirect",
      "redirect": {

Best Practices

1. Use descriptive names for rules and IPs
2. Add descriptions to explain rule purposes
3. Group related conditions logically
4. Use CIDR notation for IP ranges
5. Order rules by frequency (most common first)
6. Test rules in staging before production
7. Start with log actions before blocking
8. Keep backups of working configurations
