@app.submit("/getWalletbalance")
def getWalletbalance():
physique = request.json
params = {
"handle": physique["address"],
"community": physique["network"]
}
consequence = sol_api.account.stability(
api_key= moralis_api_key,
params = params
)
return consequenceThe “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 way to simply implement all of them, which is the important thing to easy Solana blockchain app improvement. If that pursuits you, be sure to create your free Moralis account and observe alongside!
Overview
In immediately’s article, we’ll first concentrate on a beginner-friendly Solana blockchain app improvement tutorial. The latter will educate you the way to simply work with the Solana API. By utilizing our current Solana dapp, we are going to exhibit the way to transition from NodeJS to Python backend with out affecting the JavaScript frontend. Except for the endpoint used above, this tutorial will implement your entire Solana API fleet.
The second half of this information will make it easier to higher perceive Solana and Solana blockchain improvement. That is additionally the place we are going to take a more in-depth take a look at the Solana blockchain improvement companies and sources. As such, you’ll have an opportunity to be taught extra concerning the Solana API. Because of this, you’ll be capable to decide which endpoints it is best 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 an easy JavaScript app that enables customers to make the most of the ability of the Solana API endpoints:
Notice: You may 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 high of this text, beginning at 1:05.
With a view to use Python to implement the Solana API, you could full some preliminary setups, which is strictly what the upcoming part will make it easier to with.
Setting Up Python and Solana Blockchain Improvement Providers
Earlier than shifting on, be sure to have your “Solana API demo” challenge prepared. The latter ought to comprise 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 challenge:
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 under:
cd python-backend
Then, you could create a brand new digital surroundings that may 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 surroundings:
Run the next “activate” command:
supply venv/bin/activate
Subsequent, you could set up the mandatory 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 surroundings activated and modules put in, you might proceed with organising the surroundings variables. Therefore, be sure 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 case you haven’t created your Moralis account but, do this now. Together with your account, you get to entry your admin space. There, you possibly can 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 you can Use Solana Blockchain Improvement Providers 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 embody “CORS“:
app = Flask(__name__) CORS(app)
Since you might be changing our NodeJS backend that runs on port “9000“, be sure your Python backend concentrate on the identical port. In any other case, you’d want to change the URL in your frontend. These are the strains of code that may care for 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 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, you could 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 strains of code from the introduction will get the job completed:
@app.submit("/getWalletbalance")
def getWalletbalance():
physique = request.json
params = {
"handle": physique["address"],
"community": physique["network"]
}
consequence = sol_api.account.stability(
api_key= moralis_api_key,
params = params
)
return consequenceThe 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 knowledge 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 below the “consequence” variable. Lastly, you utilize “return consequence” to return outcomes.
Python Snippets of Code for All Solana API Endpoints
On the subject of different Solana API endpoints, the very same ideas are at play. Basically, you should use the identical strains of code as introduced above. Nevertheless, you do want to alter the routes, perform names, and strategies to match the endpoint. To avoid wasting you a while, yow will discover the snippets of code for the remaining 5 Solana API endpoints under:
