Usage

Based on the node environment, this package will shuttle between the main network or the test network.

const B = require('blockstream-js-client');
 
// Create an Order on the main or test blockstream network
const { auth_token, uuid } = await B.createOrder({
  bid: '10000', // Amount in millisatoshi
  message: `Paschal's bid for a Tesla`,
});
 
// Edit Bid
B.increaseBid({
  bid_increase: '4000',
  auth_token,
  uuid,
})
  .then((res) => console.log({ res }))
  .catch((error) => console.error(error));
 
// Monitor the status of the order / Get order
B.getOrder({
  auth_token,
  uuid,
})
  .then((res) => console.log({ res }))
  .catch((error) => console.error(error));
 
// Delete Order
B.deleteOrder({
  auth_token,
  uuid,
})
  .then((res) => console.log({ res }))
  .catch((error) => console.error(error));
 
// Get pending, sent and queued orders
B.getOrders({
  state: 'pending',
})
  .then((res) => console.log({ res }))
  .catch((error) => console.error(error));
 
// Get information about the c-lightning node API
B.getInfo()
  .then((res) => console.log({ res }))
  .catch((error) => console.error(error));
 
// Subscribe to channels (The only available channel now is the "transmissions" channel)
B.subscribeToChannels(['transmissions'])
  .then((res) => console.log({ res }))
