When choosing one of many main Solana improvement instruments, the Solana API, quick 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.put up(“/getWalletbalance”)
def getWalletbalance():
       physique = request.json
      params = {
          “handle”: physique[“address”],
          “community”: physique[“network”]
          }
      end result = sol_api.account.stability(
          api_key= moralis_api_key,
          params = params
      )
      return end result

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 simply implement all of them, which is the important thing to easy Solana blockchain app improvement. If that pursuits you, be sure that to create your free Moralis account and comply with alongside!

Overview

In at the moment’s article, we’ll first concentrate on a beginner-friendly Solana blockchain app improvement tutorial. The latter will train you simply work with the Solana API. By utilizing our current Solana dapp, we’ll exhibit transition from NodeJS to Python backend with out affecting the JavaScript frontend. Other than the endpoint used above, this tutorial will implement the whole Solana API fleet. 

The second half of this information will provide help to higher perceive Solana and Solana blockchain improvement. That is additionally the place we’ll take a more in-depth have a look at the Solana blockchain improvement providers and sources. As such, you’ll have an opportunity to study extra in regards to the Solana API. Because of this, you’ll have the ability to decide which endpoints it’s best to concentrate on on your Solana blockchain app improvement feats.  

Solana Blockchain App Growth 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:

Observe: You possibly can clone the entire frontend script – “index.html” – on GitHub. In case you need a fast code walkthrough of our instance frontend dapp, try the video on the prime of this text, beginning at 1:05. 

As a way to use Python to implement the Solana API, that you must full some preliminary setups, which is precisely what the upcoming part will provide help to with.

Setting Up Python and Solana Blockchain Growth Companies 

Earlier than transferring on, be sure that to have your “Solana API demo” challenge 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 properly, you must also have a “backend” folder in your challenge:

Transferring on, begin by making a “python-backend” folder. You are able to do this manually or by way of the next command:

mkdir python-backend

Subsequent, “cd” into this new folder by working the command under:

cd python-backend

Then, that you must create a brand new digital atmosphere that may 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, that 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

Together with your digital atmosphere activated and modules put in, it’s possible you’ll proceed with establishing the atmosphere variables. Therefore, be sure 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, when you haven’t created your Moralis account but, do this now. Together with your account, you get to entry your admin space. There, you’ll be able to receive 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 one can Use Solana Blockchain Growth 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 following line, use Flask to outline a variable “app” and embody “CORS“:

app = Flask(__name__)
CORS(app)

Since you’re changing our NodeJS backend that runs on port “9000“, be sure that 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 may handle 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 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 manner to make use of these Solana blockchain improvement providers is to repeat the suitable traces of code from the Solana API reference pages. When working with Python, that 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 completed:

@app.put up(“/getWalletbalance”)
def getWalletbalance():
       physique = request.json
       params = {
          “handle”: physique[“address”],
          “community”: physique[“network”]
          }
       end result = sol_api.account.stability(
          api_key= moralis_api_key,
          params = params
       )
       return end result

The highest line – “@app.put up(“/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 (“handle” and “community“). Utilizing the “sol_api.account.stability” methodology with the parameters and your Web3 API key, you retailer the information underneath the “end result” variable. Lastly, you utilize “return end result” to return outcomes. 

Python Snippets of Code for All Solana API Endpoints

In terms of different Solana API endpoints, the very same rules are at play. Primarily, you should utilize the identical traces of code as offered above. Nevertheless, you do want to alter the routes, perform names, and strategies to match the endpoint. To avoid wasting you a while, you will discover the snippets of code for the remaining 5 Solana API endpoints under:

Implementing the “getTokenbalance” endpoint:@app.put up(“/getTokenbalance”)
def getTokenbalance():
physique = request.json
params = {
“handle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.account.get_spl(
api_key= moralis_api_key,
params = params
)
return end result Implementing the “getNfts” endpoint:  @app.put up(“/getNfts”)
def getNfts():
physique = request.json
params = {
“handle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.account.get_nfts(
api_key= moralis_api_key,
params = params
)
return end result Implementing the “getPortfolio” endpoint:@app.put up(“/getPortfolio”)
def getPortfolio():
physique = request.json
params = {
“handle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.account.get_portfolio(
api_key= moralis_api_key,
params = params
)
return end result Implementing the “getNFTMetadata” endpoint:@app.put up(“/getNFTMetadata”)
def getNFTMetadata():
physique = request.json
params = {
“handle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.nft.get_nft_metadata(
api_key= moralis_api_key,
params = params
)
return end result Implementing the “getTokenPrice” endpoint:@app.put up(“/getTokenPrice”)
def getTokenPrice():
physique = request.json
params = {
“handle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.token.get_token_price(
api_key= moralis_api_key,
params = params
)
return end result
