Route Path Syntax and Rate Limiting

Parse Server 9 standardizes the route pattern syntax across cloud routes and rate-limiting to use the new path-to-regexp v8 style. This update introduces validation and a clear deprecation error for the old wildcard route syntax.

Key Changes

• Standardization: All route paths now use the path-to-regexp v8 syntax, which provides better consistency and security.
• Validation: Added validation to ensure route paths conform to the new syntax.
• Deprecation: Old wildcard route syntax is deprecated and will trigger a clear error message.

Migration Steps

Path Syntax Examples

Update your rate limit configurations to use the new path-to-regexp v8 syntax:

Old Syntax (deprecated)	New Syntax (v8)
/functions/*	/functions/*path
/classes/*	/classes/*path
/*	/*path
*	*path

Before:

rateLimit: {
  requestPath: '/functions/*',
  requestTimeWindow: 10000,
  requestCount: 100
}

After:

rateLimit: {
  requestPath: '/functions/*path',
  requestTimeWindow: 10000,
  requestCount: 100
}

• Review your custom cloud routes and ensure they use the new path-to-regexp v8 syntax.
• Update any rate-limiting configurations to use the new route path format.
• Test your application to ensure all routes work as expected with the new syntax.

Note

Consult the path-to-regexp v8 docs and the Express 5 migration guide for more details on the new path syntax.
