Quick Start

const AlgoexplorerAPI = require("js-algoexplorer-api");
const api = new AlgoexplorerAPI();
(async () => {
    console.log(await api.status());
})().catch(e => {
    console.log(e);
});

Usage

Query address transactions

(async () => {
    console.log(await api.queryAddressTransactions(50));
})().catch(e => {
    console.log(e);
});

Query block by number

(async () => {
    console.log(await api.queryBlock(96801));
})().catch(e => {
    console.log(e);
});

Query transactions from global index

(async () => {
    console.log(await api.queryTransactionsFromInterval(150, 201));
})().catch(e => {
    console.log(e);
});

Send transaction

(async () => {
    // Get blocks count
    const blocksCount = await api.blocksCount();
    const mnemonic = "obtain extend cheap want ride fatal jungle reject field sell arm apology" +
    " avocado grit ball enough rebuild false celery favorite cook soon talk abandon hope";
    const keys = algosdk.mnemonicToSecretKey(mnemonic);
    // Prepare transaction
    const txn = {
        "from": keys.addr,
        "to": "46QNIYQEMLKNOBTQC56UEBBHFNH37EWLHGT2KGL3ZGB4SW77W6V7GBKPDY",
        "fee": 1000,
        "amount": 10000,
        "firstRound": blocksCount + 1,
        "lastRound": blocksCount + 100,
        "genesisID": client.getGenesisId(),
        "genesisHash": client.getGenesisHash(),
        "note": new Uint8Array(0)
    };
    const signedTxn = algosdk.signTransaction(txn, keys.sk);
    const hexa = Buffer.from(signedTxn.blob).toString('hex');
    // Send transaction
    await api.sendTransaction(hexa);
})().catch(e => {
    console.log(e);
});
