Flow SDK

Installation

npm i -S @rarible/flow-sdk

Usage

Simple code example

Quick start

1. Configure fcl
2. Create and use flow-sdk

Configure fcl

Flow-sdk use @onflow/fcl-js. You can find configuration details for fcl in this page

//example config for testnet
import { config } from "@onflow/fcl";

config({
  "accessNode.api": "https://access-testnet.onflow.org", // Mainnet: "https://access-mainnet-beta.onflow.org"
  "discovery.wallet": "https://fcl-discovery.onflow.org/testnet/authn" // Mainnet: "https://fcl-discovery.onflow.org/authn"
})

Create and use flow-sdk

Then we create the SDK according to the network that we configured in the previous step.

import { createFlowSdk } from "@rarible/flow-sdk"
import * as fcl from "@onflow/fcl"

const sdk = createFlowSdk(fcl, "testnet")

Minting

Mint response represents transaction result extended with txId and minted tokenId

import { toFlowContractAddress } from "@rarible/flow-sdk"
import { toFlowAddress } from "@rarible/types"

// collection = Contact address A.[contactAddress].[contractName]
const collection = toFlowContractAddress("A.0x1234567890abcdef.RaribleNFT")
// royalties - array of objects: {account: FlowAddress, value: BigNumber}, value must be a number between 0 and 1
const royalties = [{ account: toFlowAddress("0x1234567890abcdef"), value: toBigNumber("0.1") }]
const metaData = "your meta info" // usually ipfs url

const { tokenId } = await sdk.nft.mint(collection, metaData, royalties)

Returns FlowTransaction object with minted tokenId

Transfer

import { toFlowAddress } from "@rarible/types"
import { toFlowContractAddress } from "@rarible/flow-sdk"

const collection = toFlowContractAddress("A.0x1234567890abcdef.RaribleNFT")
const tokenId = 123
const receiver = toFlowAddress("0x1234567890abcdef")

const tx = await sdk.nft.transfer(collection, tokenId, receiver)

Returns FlowTransaction object

Burn

import { toFlowContractAddress } from "@rarible/flow-sdk"

const collection = toFlowContractAddress("A.0x1234567890abcdef.RaribleNFT")
const tokenId = 123

const tx = await sdk.nft.burn(collection, tokenId)

Returns FlowTransaction object

Create sell order

import { toFlowContractAddress, toFlowItemId } from "@rarible/flow-sdk"

const collection = toFlowContractAddress("A.0x1234567890abcdef.RaribleNFT")
const itemId = toFlowItemId(`${collection}:123`)
const tx = await sdk.nft.sell(collection, currency, itemId, price)

/** supported currencies for now "FLOW" and "FUSD" */

/** FlowItemId you can find in FlowNftItem response from api,
 for example sdk.apis.item.getNftItemsByOwner({address: <your account address>})
 */

/** price must be a string of flow fungible token amount with 8 decimals,  for example: 1.123 or 0.1 or 0.00000001 */

Returns FlowTransaction object with orderId

Update order

const tx = await sdk.nft.updateOrder(collection, currency, orderId, price)
// orderId can be a orderId number or full FlowOrder object received from order api

Returns FlowTransaction object with updated orderId

Cancel order

const tx = await sdk.nft.cancelOrder(collection, orderId)

Returns FlowTransaction object

Buy an item

const tx = await sdk.nft.fill(collection, orderId, owner)
// owner: FlowAddress - order owner address

Returns FlowTransaction object

Create bid

import { toFlowContractAddress, toFlowItemId } from "@rarible/flow-sdk"

const collection = toFlowContractAddress("A.0x1234567890abcdef.RaribleNFT")
const itemId = toFlowItemId(`${collection}:123`)
const tx = await sdk.nft.bid(collection, currency, itemId, price)
// params the same as regular order creation

Returns FlowTransaction object with orderId

Update bid

const tx = await sdk.nft.updateBid(collection, currency, bidId, price)

Returns FlowTransaction object with updated orderId

Cancel bid

const tx = await sdk.nft.cancelBid(collection, bidId)

Returns FlowTransaction object

Accept bid

The same as buy order sdk.order.fill

Get account fungible tokens balance

const balance = await sdk.wallet.getFungibleBalance(accountAddress, "FUSD")
