Sentio Composer - Execute View Functions on Aptos Blockchain

This project can be used to call view functions on the aptos blockchain. Given the input of the function and the corresponding ledger version, tool can execute that function and return the corresponding result.

It doesn't require the view functions as entry functions, and now supports the networks including mainnet, testnet and devnet.

This project includes a CLI tool and we've also built a demo web app on top of it. You can choose to use the CLI tool or directly start the web application locally via docker.

How it works

Start the Web Application with Docker

sudo docker run --env BIN_PATH="/app/view-function" -d -p 8080:4000 poytr1/sentio-composer-app:latest

Then open http://localhost:8080/ to use it.

Install the CLI tool

You can choose to build the CLI tool on your own or download the binary directly from release page.

To build it on your own:

Install the Rust and Cargo

curl https://sh.rustup.rs -sSf | sh

To install the CLI tool globally

cargo install --git https://github.com/sentioxyz/sentio-composer

To build debug or release binary locally

Clone the project, and run cargo build in the root of the project.
Release build, run cargo build --release.
Check the target folder, you should find the binary target/debug/view-function or target/release/view-function.

CLI Usage

Run the CLI

view-function -h

Call the view function on Aptos blockchain

Usage: view-function [OPTIONS] --function-id <FUNCTION_ID>

Options:
  -f, --function-id <FUNCTION_ID>
          Function name as `<ADDRESS>::<MODULE_ID>::<FUNCTION_NAME>`
  -a, --args [<ARGS>...]
          Arguments separated by spaces
  -t, --type-args [<TYPE_ARGS>...]
          TypeTag arguments separated by spaces
  -l, --ledger-version <LEDGER_VERSION>
          Ledger version, if not apply or 0, use the latest ledger version [default: 0]
  -n, --network <NETWORK>
          Network to use [default: mainnet] [possible values: mainnet, testnet, devnet]
  -c, --config <CONFIG>
          Config file to use
      --log-level <LOG_LEVEL>
          Log level [default: off] [possible values: off, error, warn, info, debug, trace]
  -h, --help
          Print help information (use `--help` for more detail)
  -V, --version
          Print version information

Example

# command
view-function \
--function-id 0x1::coin::balance \
--type-args 0x1::aptos_coin::AptosCoin \
--args 0x21ddba785f3ae9c6f03664ab07e9ad83595a0fa5ca556cec2b9d9e7100db0f07 \
--ledger-version 35842267 \
--network mainnet
# output
{
  "log_path": "",
  "return_values": [
    3120544100
  ]
}

Config file

You can also write some static configurations like log folder and network url settings to a local configuration file, the default file is config.toml in the tool running directory. Here is an example:

[config]
log_folder = ".log"
cache_folder = "."
network_configs = { testnet = "https://fullnode.mainnet.aptoslabs.com/v1" }

Logs

The default log folder is .log in the tool running directory.

Web App

We also build a web app on top of the CLI tool, but it's for demo purpose only.

To start the web service:

cd app/server
npm install
npm run start

To start the frontend in dev mode

cd app/client
npm install
npm run serve

Now open http://localhost:8080/, you should find the App is up:
