Consequently, you’ll have the ability to decide which endpoints it is best to deal with to your Solana blockchain app improvement feats.
Solana Blockchain App Improvement with the Solana API
As talked about above and because the above picture illustrates, this Solana blockchain app improvement tutorial focuses on shifting the backend from NodeJS to Python with out affecting the frontend. The latter is a straightforward JavaScript app that permits customers to make the most of the facility of the Solana API endpoints:
Notice: You’ll be able to clone the whole frontend script – “index.html” – on GitHub. In case you need a fast code walkthrough of our instance frontend dapp, take a look at the video on the high of this text, beginning at 1:05.
In an effort to use Python to implement the Solana API, it’s good to full some preliminary setups, which is precisely what the upcoming part will show you how to with.
Setting Up Python and Solana Blockchain Improvement Companies
Earlier than shifting on, ensure that to have your “Solana API demo” venture prepared. The latter ought to include a “frontend” folder, which incorporates the above-mentioned “index.html” script, presuming you cloned our code. In case you probably did clone our NodeJS backend as nicely, you must also have a “backend” folder in your venture:
Transferring on, begin by making a “python-backend” folder. You are able to do this manually or through the next command:
mkdir python-backend
Subsequent, “cd” into this new folder by operating the command beneath:
cd python-backend
Then, it’s good to create a brand new digital atmosphere that can assist the set up and use of Python modules. As such, enter this into your terminal:
python3 -m venv venv
You additionally must activate your digital atmosphere:
Run the next “activate” command:
supply venv/bin/activate
Subsequent, it’s good to set up the mandatory modules. The command beneath will set up Flask, Flask CORS, Moralis, and Python “dotenv”:
pip set up flask flask_cors moralis python-dotenv
Together with your digital atmosphere activated and modules put in, chances are you’ll proceed with establishing the atmosphere variables. Therefore, ensure that to acquire your Moralis Web3 API key. The latter is the gateway to Solana blockchain app improvement with the Solana API from Moralis. So, for those who haven’t created your Moralis account but, try this now. Together with your account, you get to entry your admin space. There, you possibly can acquire your Web3 API key within the following two steps:
Create a brand new “.env” file or copy it from the NodeJS backend folder and populate the “MORALIS_API_KEY” variable with the above-obtained API key.
The way to Use Solana Blockchain Improvement Companies with Python
To implement the Moralis Solana API endpoints with Python, create a brand new “index.py” file inside your “python-backend” folder. Then, import the above-installed packages and the highest of that script:
from flask import Flask, request from flask_cors import CORS from moralis import sol_api from dotenv import dotenv_values
You additionally need this script to fetch your Web3 API key, which you retailer within the “.env” file:
config = dotenv_values(".env")
moralis_api_key = config.get("MORALIS_API_KEY")
On the subsequent line, use Flask to outline a variable “app” and embrace “CORS“:
app = Flask(__name__) CORS(app)
Since you’re changing our NodeJS backend that runs on port “9000“, ensure that your Python backend deal with the identical port. In any other case, you’d want to switch the URL in your frontend. These are the strains of code that can deal with that:
if __name__ == "__main__": app.run(debug=True, host="0.0.0.0", port=9000)
Transferring additional down your “index.py” script, it’s time you begin implementing the Moralis Solana API endpoints: “Get native steadiness by pockets”, “Get token steadiness by pockets”, “Get portfolio by pockets”, “Get token value”, “Get NFTs by pockets”, and “Get NFT metadata”.
The only means to make use of these Solana blockchain improvement companies is to repeat the suitable strains of code from the Solana API reference pages. When working with Python, it’s good to choose that programming language. Right here’s the “Get native steadiness by pockets” endpoint reference web page:
Implementing Solana API Endpoints
Return to your “index.py” script to outline routes and features for every endpoint beneath the “CORS(app)” line. So far as the “get native steadiness by pockets” endpoint goes, the strains of code from the introduction will get the job accomplished:
@app.submit("/getWalletbalance")
def getWalletbalance():
physique = request.json
params = {
"tackle": physique["address"],
"community": physique["network"]
}
outcome = sol_api.account.steadiness(
api_key= moralis_api_key,
params = params
)
return outcome
The highest line – “@app.submit(“/getWalletbalance“) – creates a brand new route in Python. With “def getWalletbalance():“, you outline the operate for the endpoint at hand. Utilizing “physique = request.json“, you learn the JSON knowledge that Moralis fetches and parses for you. Then, you outline the endpoint’s parameters (“tackle” and “community“). Utilizing the “sol_api.account.steadiness” technique with the parameters and your Web3 API key, you retailer the info below the “outcome” variable. Lastly, you employ “return outcome” to return outcomes.
Python Snippets of Code for All Solana API Endpoints
