Prerequisites

Ensure Node.js is installed on your system to run and install Sprout.

Quickstart

In order to use the tool, you must have Chia Wallet and Chia DataLayer running. You also need some mojos in order to cover the fees when creating datalayer transactions such as creating a new store and pushing data to the datalayer. Sprout works best when installed as a global npm package.

1. Install chia-sprout-cli globally by running:

   $ npm install chia-sprout-cli -g
   

2. Navigate to your project directory and initialize your project:

   $ sprout init
   

   This creates a sprout.config.json file in your working directory. Review the file to make sure the configuration works with your setup.

3. Create a new store:

   $ sprout store create
   

4. Deploy your project to datalayer:

   $ sprout deploy
   

5. Make sure your mirror is discoverable by the peer network

   $ sprout status
   

6. View your files in the browser:

   $ sprout web2
   

   Your store will now be viewable at https://localhost:41410/<store_id>.

Mirroring Your Datastore

To create a local mirror allowing others to subscribe to your store (aka make your store public), follow these steps:

1. Activate the DataLayer File Propagation Server in the Chia UI Settings. This server comes with Chia.

2. Ensure your firewall permits inbound/outbound traffic on port 8575, the default datalayer port.

3. If necessary, forward local router port 8575->8575. (Instructions vary by router.)

4. Run the following command using the sprout tool:

   sprout store mirror
   

   This command automatically creates a mirror from the store in your sprout.config.json file, making your store available for subscription.

Compile Binary (optional)

Instead of running sprout as a npm command, you can build your own binary with the following steps.

Clone the repository, navigate into the directory, and then install the required dependencies:

npm install

You can build the tool into an executable with one of the the following commands:

npm run create-win-x64-dist

npm run create-mac-x64-dist

npm run create-linux-x64-dist

npm run create-linux-arm64-dist

This will create an executable file named "sprout" in the build folder.

Usage

The Sprout CLI tool provides the following commands:

$ sprout init

This command creates a sprout.config.json file in the current working directory with the default JSON:

{
  "store_id": null,
  "deploy_dir": "./build",
  "datalayer_host": "https://localhost:8562",
  "wallet_host": "https://localhost:9256",
  "certificate_folder_path": "~/.chia/mainnet/config/ssl",
  "default_wallet_id": 1,
  "default_fee": 300000000,
  "default_mirror_coin_amount": 300000000,
  "maximum_rpc_payload_size": 26214400
}

$ sprout deploy

This command deploys the files in the directory specified in sprout.config.json to the data layer. An error will occur if there is no store_id specified in the configuration file or if sprout.config.json does not exist.

$ sprout store create [--new]

This command creates a new data layer store and updates the store_id value in sprout.config.json. If an existing store_id is present in the configuration file, it throws an error, unless the --new flag is passed. An error will also occur if sprout.config.json does not exist.

$ sprout store clean

This command deletes all items from the current store. An error will be thrown if a store_id is not specified in sprout.config.json.

$ sprout web2

This command starts a web2 gateway server for development purposes. When you run this you can now view the files your just deployed to the datalayer.

$ sprout help

This command prints out all available commands in the console.

$ sprout test

Check Chia Config IP Host (checkChiaConfigIpHost): This function is responsible for loading the Chia configuration file from ~/.chia/mainnet/config/config.yaml and verifying that the data_layer.ip_host is correctly set to either 0.0.0.0 or an empty string (but not null). It utilizes the chia-root-resolver module to accurately locate the Chia root directory. The function returns a boolean indicating whether the ip_host is correctly set.

Check File Propagation Server Reachability (checkFilePropagationServerReachable): This function determines the user's IPv4 and IPv6 addresses and sends them to a yet-to-be-built endpoint. The purpose is to check if the local file propagation server is reachable from the outside world. The function leverages a method from the chia-datalayer-mirror-tools repository to obtain the IP addresses, using publicIpv4({forceIp4: true}) for IPv4 and publicIpv4() for IPv6. The information will be sent to https://api.datalayer.storage/system/v1/check_server with a POST request, and the endpoint will return a success status.

Configuration

The Sprout CLI uses a configuration file (sprout.config.json) to specify various settings such as the data layer store ID (store_id), the directory of files to be deployed (deploy_dir), the data layer host (datalayer_host), the wallet host (wallet_host), the location of your certificate folder (certificate_folder_path), and some default values for wallet ID, fee, mirror coin amount, and RPC payload size.

Certificate and Key Configuration

Sprout CLI supports environment variable configuration for certificate and key files necessary for communication with a remote data layer. This can be particularly useful when working in a CI pipeline.

To provide the certificate and key as base64 strings, you can set the following environment variables:

• CERT_BASE64
• KEY_BASE64

For example:

export CERT_BASE64="your base64 encoded certificate"
export KEY_BASE64="your base64 encoded key"

If these environment variables are set, Sprout CLI will use these for the certificate and key. Otherwise, it will look for the files at the default location as specified in your sprout.config.json.
