Aqua CLI

Aqua CLI allows you to manage all aspects of Aqua development and includes:

• Compiler
• Client Peer
• Utilities

To install the Aqua CLI package:

npm install -g @fluencelabs/aqua

Compiler

The compiler turns high-level Aqua code into either JS/TS handlers wrapping AIR, the default, or pure AIR.

The quickest way to compile Aqua code is to take all .aqua files from the specified input directory, e.g., src/aqua, and place the generated JavaScript code in some output directory of your choosing, e.g. src/generated. Please note that if the specified output directory does not exist, the CLI creates it for you:

aqua --input src/aqua --output src/generated

Of course, we can be more specific and name a filename:

aqua --input src/aqua/some_file.aqua --output src/generated

As mentioned in the intro, the Aqua compiler generates .js with .d.ts TypeScript files by default. Output files will contain functions exported from .aqua files and methods for registering defined services. You can read more about calling functions and service registration in the FluenceJS documentation.

Additional compiler options are:

• --js flag, which generates only .js files
• --air or -a flag, which generates pure AIR code
• --scheduled, which generates AIR code suitable for script storage

Use aqua --help for a complete listing of available flags, subcommands and explanations.

Subcommands

The CLI provides additional features and utilities via subcommands.

Aqua Run

The aqua run command creates a one-shot client peer over the compiled Aqua code specified allowing you to quickly and effectively test Aqua code against deployed services on the network.

aqua run --addr <relay multidaddress> --input <your aqua filepath> --func '<function name>(<args>)'

For the following Aqua script:

-- some-dir/hello.aqua
service Hello("service_id"):
    hello(name:string) -> string
    
func hello(name: string, node:string, sid: string) -> string:
    on node:
        Hello sid
        res <- Hello.hello(name)
    <- res    

We instantiate our aqua client peer:

aqua run --addr /dns4/.../wss/p2p/12D3 ...aoHI --input some-dir/hello.aqua --func 'hello("reader", "peer id", ["service id1", "service id2"])'

The aqua run command provides additional features such as:

• --sk or -s allows you to provide your secret key (sk) in base64
• --addr or -a allows you to specify a relay in multiaddr format, e.g., /dns4/kras-04.fluence.dev/tcp/19001/wss/p2p/12D3KooWFEwNWcHqi9rtsmDhsYcDbRUCDXH84RC4FW6UfsFWaoHi . The aqua config default_peers <krasnodar, testnet, stage> command enumerates you the respective network multiaddresses of available Fluence nodes.

--import or -m allows you to import functionality from one or more source folders by using the flag repeatedly

• --data or -d allows you to specify data arguments as a json map:

  aqua run --addr /dns4/.../wss/p2p/12D3 ... oHI --input my_code.aqua --func 'my_aqua_func(a, b)' --data '{"a": "some_string", "b": 123}'
  

• --data-path or p allows you to specify data arguments, see --data, as a file. Note that --data and --data-path are mutually exclusive.

• --json-service or -j allows you to describe a service that will return a JSON. This service must be described in Aqua. There can be multiple functions strictly without any arguments. Also, you can use this flag multiple times targeting multiple services in different files. There is an example of a service description in Aqua and JSON:

-- aqua file
data SomeResult:
  field1: string
  num2: i32

service ServiceName("some id"):
  funcName: -> SomeResult

{
  "name": "ServiceName",
  "serviceId": "some id",
  "functions": [{
    "name": "funcName",
    "result": {
      "field1": "result 1",
      "num2": 5
    }
  }]
}

Use aqua run --help for a complete listing of available flags and explanations.

Aqua Create Keypair

The aqua key create utility allows you to create an ed25519-based keypair in base64:

aqua key create

And produces the following json document:

{
    "peerId": "12D3KooWMC6picJQNruwFMFWqP62FWLtbM94TGYEzCsthsKa46CQ",
    "secretKey": "QG3Ot2i1kD4Mpw0RpsKtUjbA/0XjZ0WP7dajDBwLQi0=",
    "publicKey": "CAESIKkB+6eYhFDsEZhn0u+xwIKVhE+1xvgJoV5/csc+CS6R"
}

Aqua Module Distribution

A critical step is to get our WASm modules and service configuration files to our target hosts. The Aqua cli provides the capability to upload and configure our assets into hosted services under the aqua remote namespace:

aqua remote --help
Usage:
    ...
    aqua remote deploy_service
    aqua remote remove_service
    ...

Subcommands:
    ...
    deploy_service
        Deploy service from WASM modules
    remove_service
        Remove service
    ...

See the service management section for details and examples.

Aqua Environments Listing

The aqua config default_peers utility shows a list of peers in multiaddr format for a specific Fluence network. Currently, there are three environments: krasnodar, the default network,stage and testnet.

aqua config default_peers testnet

shows a list of testnet peers:
