Here is an example of how to connect to the Binance API and buy spot using JavaScript

const Binance = require('binance-api-node').default;

// Replace with your Binance API key
const client = Binance({
  apiKey: 'YOUR_API_KEY',
  apiSecret: 'YOUR_API_SECRET',
});

// Replace with the symbol of the spot market you want to buy
const symbol = 'BTCUSDT';

// Replace with the quantity of the spot market you want to buy
const quantity = 1;

client.order({
  symbol: symbol,
  side: 'BUY',
  type: 'MARKET',
  quantity: quantity
})
  .then((response) => {
    console.log(response);
    // Handle success
  })
  .catch((error) => {
    console.error(error);
    // Handle error
  });

Here is the example on how to open a long position on Future market with stoploss
