Server config

Host and port

Specify the host and the port used by the server with --host <ADDRESS> and --port <NUMBER> CLI arguments. If running with Docker, check out the port publishing docs.

Logging

By default, the logging level is INFO, but this can be changed via the RUST_LOG environment variable.

All logging levels: TRACE, DEBUG, INFO, WARN, ERROR

To specify the logging level and run Devnet on the same line:

$ RUST_LOG=<LEVEL> starknet-devnet

or if using dockerized Devnet:

$ docker run -e RUST_LOG=<LEVEL> shardlabs/starknet-devnet-rs

By default, logging of request and response data is turned off. To see the request and/or response body, additional levels can be specified via the RUST_LOG environment variable: REQUEST for request body, RESPONSE for response body.

note

Logging request and response requires at least logging level INFO.

For example, the following two commands will log request and response data with log level INFO.

$ RUST_LOG="REQUEST,RESPONSE" starknet-devnet

$ RUST_LOG="REQUEST,RESPONSE,INFO" starknet-devnet

Timeout

Specify the maximum amount of time an HTTP request can be served. This makes it possible to deploy and manage large contracts that take longer to execute.

$ starknet-devnet --timeout <SECONDS>

Request body size limit

Specify the maximum size of an incoming HTTP request body. This makes it possible to deploy and manage large contracts that take up more space.

$ starknet-devnet --request-body-size-limit <BYTES>

API

Retrieve the server config by sending a GET request to /config and extracting its server_config property.

$ curl localhost:5050/config | jq .server_config
