Oracle Redstone: How to make your dApps more reliable and scalable
- Install the RedStone Oracle library. The RedStone Oracle library is available for Node.js, Python, and Java. You can find the installation instructions for your specific language on the RedStone Oracle website.
- Create a new dapp project. You can use any framework you like to create your dapp project. Once you have created your project, you need to install the RedStone Oracle library.
- Import the RedStone Oracle library. In your dapp project, you need to import the RedStone Oracle library. You can do this by adding the following line to your code:
import RedstoneOracle from 'redstone-oracle';
- Create a new RedStone Oracle client. Once you have imported the RedStone Oracle library, you need to create a new RedStone Oracle client. You can do this by calling the
createClient()
method:
const client = RedstoneOracle.createClient();
- Query the RedStone Oracle. Once you have created a new RedStone Oracle client, you can query the RedStone Oracle. You can do this by calling the
query()
method:
const result = client.query('price', 'ETH');
This will query the RedStone Oracle for the current price of ETH. The result
variable will contain the result of the query.
- Use the result. You can use the result of the query to do whatever you want in your dapp. For example, you could display the current price of ETH to the user, or you could use the price to make a financial decision.
Here is an example of how to use the result of the query to display the current price of ETH to the user:
const price = result.data.price; const div = document.getElementById('price'); div.innerHTML = `The current price of ETH is ${price}.`;
This will display the current price of ETH in the price
div element.
