arg

A utility builder to be used with fcl.args[...] to create FCL supported arguments for interactions.

Arguments are used to pass data to Cadence scripts and transactions. The arguments must match the number and order declared in the Cadence script.

Import

You can import the entire package and access the function:

_10

import * as sdk from "@onflow/sdk"

_10

_10

sdk.arg(value, xform)

Or import directly the specific function:

_10

import { arg } from "@onflow/sdk"

_10

_10

arg(value, xform)

Usage

import * as fcl from "@onflow/fcl"

_15

_15

const result = await fcl.query({

_15

cadence: `

_15

access(all) fun main(a: Int, b: Int, addr: Address): Int {

_15

log(addr)

_15

return a + b

_15

}

_15

`,

_15

args: (arg, t) => [

_15

arg(7, t.Int), // a: Int

_15

arg(6, t.Int), // b: Int

_15

arg("0xba1132bc08f82fe2", t.Address), // addr: Address

_15

],

_15

});
