## New relayer architecture
|
||||
|
||||
1. TreeWatcher module keeps track of Account Tree changes and automatically caches the actual state in Redis
|
||||
2. Server module is Express.js instance to accepts http requests
|
||||
3. Controller contains handlers for the Server endpoints. It validates input data and put a Job to Queue
|
||||
4. Queue module is used by Controller to put and get Job from queue (bull wrapper)
|
||||
5. Status module contains handler to get a Job status. It's used by UI for pull updates
|
||||
6. Validate contains validation logic for all endpoints
|
||||
7. Worker is the main module that gets a Job from queue and processes it
