Overview
In as we speak’s article, we’ll first deal with a beginner-friendly Solana blockchain app growth tutorial. The latter will train you find out how to simply work with the Solana API. Through the use of our current Solana dapp, we are going to exhibit find out how 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 provide help to higher perceive Solana and Solana blockchain growth. That is additionally the place we are going to take a more in-depth have a look at the Solana blockchain growth companies and sources. As such, you’ll have an opportunity to be taught extra in regards to the Solana API. In consequence, you’ll be capable to decide which endpoints you need to deal with to your Solana blockchain app growth feats.
Solana Blockchain App Improvement with the Solana API
As talked about above and because the above picture illustrates, this Solana blockchain app growth 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 may clone the whole 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.
With a view 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 Improvement Companies
Earlier than transferring on, ensure that to have your “Solana API demo” mission 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 mission:
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 operating the command under:
cd python-backend
Then, that you must create a brand new digital surroundings 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 surroundings:
Run the next “activate” command:
supply venv/bin/activate
Subsequent, that you must 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
Along with your digital surroundings activated and modules put in, you might proceed with organising the surroundings variables. Therefore, ensure that to acquire your Moralis Web3 API key. The latter is the gateway to Solana blockchain app growth with the Solana API from Moralis. So, should you haven’t created your Moralis account but, try this now. Along with your account, you get to entry your admin space. There, you may 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.
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’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 change 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 best means to make use of these Solana blockchain growth companies is to repeat the suitable strains 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 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 under 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 achieved:
@app.submit(“/getWalletbalance”)
def getWalletbalance():
physique = request.json
params = {
“tackle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.account.steadiness(
api_key= moralis_api_key,
params = params
)
return end result
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 (“tackle” and “community“). Utilizing the “sol_api.account.steadiness” 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
With regards to different Solana API endpoints, the very same rules are at play. Primarily, you should use the identical strains of code as introduced above. Nevertheless, you do want to vary the routes, perform names, and strategies to match the endpoint. To save lots of you a while, you will discover the snippets of code for the remaining 5 Solana API endpoints under:
Implementing the “getTokenbalance” endpoint:@app.submit(“/getTokenbalance”)
def getTokenbalance():
physique = request.json
params = {
“tackle”: 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.submit(“/getNfts”)
def getNfts():
physique = request.json
params = {
“tackle”: 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.submit(“/getPortfolio”)
def getPortfolio():
physique = request.json
params = {
“tackle”: 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.submit(“/getNFTMetadata”)
def getNFTMetadata():
physique = request.json
params = {
“tackle”: 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.submit(“/getTokenPrice”)
def getTokenPrice():
physique = request.json
params = {
“tackle”: physique[“address”],
“community”: physique[“network”]
}
end result = sol_api.token.get_token_price(
api_key= moralis_api_key,
params = params
)
return end result
