# Mango Client
A client to engage with the mango program
### Example
```
async function main() {
const client = new MangoClient()
const cluster = 'mainnet-beta'
const clusterUrl = process.env.CLUSTER_URL || IDS.cluster_urls[cluster]
const connection = new Connection(clusterUrl, 'singleGossip')
const programId = new PublicKey(IDS[cluster].mango_program_id)
const dexProgramId = new PublicKey(IDS[cluster].dex_program_id)
const mangoGroupPk = new PublicKey(IDS[cluster].mango_groups['BTC_ETH_USDT'].mango_group_pk)
const keyPairPath = process.env.KEYPAIR || homedir() + '/.config/solana/id.json'
const payer = new Account(JSON.parse(fs.readFileSync(keyPairPath, 'utf-8')))
const mangoGroup = await client.getMangoGroup(connection, mangoGroupPk)
const prices = await mangoGroup.getPrices(connection)
const marginAccounts = (await client.getMarginAccountsForOwner(connection, programId, mangoGroup, payer))
marginAccounts.sort(
(a, b) => (a.computeValue(mangoGroup, prices) > b.computeValue(mangoGroup, prices) ? -1 : 1)
)
let marginAccount = marginAccounts[0]
const market = await Market.load(connection, mangoGroup.spotMarkets[0], { skipPreflight: true, commitment: 'singleGossip'}, mangoGroup.dexProgramId)
console.log('placing order')
const txid = await client.placeOrder(connection, programId, mangoGroup, marginAccount, market, payer, 'buy', 48000, 0.0001)
console.log('order placed')
await sleep(5000)
marginAccount = await client.getMarginAccount(connection, marginAccount.publicKey, mangoGroup.dexProgramId)
const bids = await market.loadBids(connection)
const asks = await market.loadAsks(connection)
console.log('canceling orders')
await marginAccount.cancelAllOrdersByMarket(connection, client, programId, mangoGroup, market, bids, asks, payer)
console.log('orders canceled')
