When choosing one of many main Solana improvement instruments, the Solana API, brief code snippets do all of the blockchain-related backend work. Right here’s an instance of the API in motion fetching balances of a pockets:  

@app.submit("/getWalletbalance")
def getWalletbalance():
       physique = request.json
      params = {
          "deal with": physique["address"],
          "community": physique["network"]
          }
      consequence = sol_api.account.stability(
          api_key= moralis_api_key,
          params = params
      )
      return consequence

The “sol_api.account.stability” methodology is simply one of many highly effective strategies within the Moralis Solana API set. On this article, we’ll present you the best way to simply implement all of them, which is the important thing to easy Solana blockchain app improvement. If that pursuits you, be certain to create your free Moralis account and comply with alongside!

Overview

In immediately’s article, we’ll first concentrate on a beginner-friendly Solana blockchain app improvement tutorial. The latter will train you the best way to simply work with the Solana API. Through the use of our present Solana dapp, we’ll reveal the best way to transition from NodeJS to Python backend with out affecting the JavaScript frontend. Apart from the endpoint used above, this tutorial will implement the whole Solana API fleet. 

The second half of this information will assist you higher perceive Solana and Solana blockchain improvement. That is additionally the place we’ll take a better take a look at the Solana blockchain improvement companies and assets. As such, you’ll have an opportunity to be taught extra in regards to the Solana API. Consequently, you’ll have the ability to decide which endpoints you need to concentrate on 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:

Be aware: You’ll be able to clone the entire 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. 

With the intention to use Python to implement the Solana API, you must full some preliminary setups, which is strictly what the upcoming part will assist you with.

Setting Up Python and Solana Blockchain Improvement Companies 

Earlier than shifting on, be certain 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 also needs to have a “backend” folder in your venture:

Shifting 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 working the command under:

cd python-backend

Then, you must create a brand new digital setting that can help 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 setting:

Run the next “activate” command:

supply venv/bin/activate

Subsequent, you must set up the required modules. The command under will set up Flask, Flask CORS, Moralis, and Python “dotenv”:

pip set up flask flask_cors moralis python-dotenv

Along with your digital setting activated and modules put in, it’s possible you’ll proceed with establishing the setting variables. Therefore, be certain to acquire your Moralis Web3 API key. The latter is the gateway to Solana blockchain app improvement with the Solana API from Moralis. So, in the event you haven’t created your Moralis account but, do this now. Along with your account, you get to entry your admin space. There, you’ll be able to get hold of 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.

How you can 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 might be changing our NodeJS backend that runs on port “9000“, be certain your Python backend concentrate on the identical port. In any other case, you’d want to switch the URL in your frontend. These are the traces of code that can handle that:

if __name__ == "__main__":
    app.run(debug=True, host="0.0.0.0", port=9000)

Shifting additional down your “index.py” script, it’s time you begin implementing the Moralis Solana API endpoints: “Get native stability by pockets”, “Get token stability by pockets”, “Get portfolio by pockets”, “Get token value”, “Get NFTs by pockets”, and “Get NFT metadata”.

The only approach to make use of these Solana blockchain improvement companies is to repeat the suitable traces of code from the Solana API reference pages. When working with Python, you must choose that programming language. Right here’s the “Get native stability by pockets” endpoint reference web page:

Implementing Solana API Endpoints

Return to your “index.py” script to outline routes and features for every endpoint under the “CORS(app)” line. So far as the “get native stability by pockets” endpoint goes, the traces of code from the introduction will get the job achieved:

@app.submit("/getWalletbalance")
def getWalletbalance():
       physique = request.json
       params = {
          "deal with": physique["address"],
          "community": physique["network"]
          }
       consequence = sol_api.account.stability(
          api_key= moralis_api_key,
          params = params
       )
       return consequence

The highest line – “@app.submit(“/getWalletbalance“) – creates a brand new route in Python. With “def getWalletbalance():“, you outline the perform for the endpoint at hand. Utilizing “physique = request.json“, you learn the JSON information that Moralis fetches and parses for you. Then, you outline the endpoint’s parameters (“deal with” and “community“). Utilizing the “sol_api.account.stability” methodology with the parameters and your Web3 API key, you retailer the info beneath the “consequence” variable. Lastly, you employ “return consequence” to return outcomes. 

Python Snippets of Code for All Solana API Endpoints

In the case of different Solana API endpoints, the very same ideas are at play. Primarily, you should utilize the identical traces of code as introduced above. Nonetheless, you do want to vary the routes, perform names, and strategies to match the endpoint. To avoid wasting you a while, you’ll find the snippets of code for the remaining 5 Solana API endpoints under:
