LightweightNanoRPCProxy

This is a web server that acts as a middleman between the user and the actual NANO node in order to limit the allowed RPC actions and adds rate limit and basic logging.

Setup

Rename config.example.json to config.json and change values accordingly.

Then run:

npm install

node app.js

Configurable options

• LOG_DATA: Logs the returned HTTP statuses that each user received and first/last request date.
• TRUST_PROXY: Enable this if you're behind a reverse proxy like nginx & cloudflare.
• NODE_RPC: Node RPC url.
• API_ROUTE: Customize target api route.
• PORT: Port this proxy web server will run.
• AVAILABLE_ACTIONS: Array of allowed RPC actions.
• REQUESTS_LIMIT: Amount of requests each IP is allowed to make per hour.
• USERS: Array of users.
  • username: Just an alias, not actually used (yet?)
  • token: Randomly generated token that is supposed to be sent in the Authorization header (eg: Authorization: random_string_here)
  • extra_available_actions: You can add extra actions that this user can run.
  • NOTE: All authorized users bypass the rate limiter completely.
• SUPER_IPS: Array of IPs that will not use the rate limiter.
• MAX_ACTIONS_COUNT: Limit the value of the "count" parameter for selected actions
• MAX_REQUESTED_ACCOUNTS_COUNT: Limit the amount of the "accounts" array for selected actions

Extra

You can run node preview_logs.js if you want to view the logs.
