I cannot install sql.js properly

I'm trying to create a database on the client-side using sql.js and vanilla js. I guess, there is some problem within the installation process. I've done the 'npm install sql.js' and included the CDN. I get this error from the console 'Uncaught ReferenceError: require is not defined'

(BTW this my first question on here, open to suggestions...)

This is pretty much the expression shown in the documentation on their website. I can't make it work, though. Is it because of node.js or something else?

<script type="module">
            const initSqlJs = require('/sql.js');

            const SQL = await initSqlJs({
                locateFile: (file) =>
                    'https://cdnjs.cloudflare.com/ajax/libs/sql.js/1.8.0/sql-wasm.js',
            });
            const db = new SQL.Database();

            let sqlstr =
                "CREATE TABLE hello (a int, b char); \
            INSERT INTO hello VALUES (0, 'hello'); \
            INSERT INTO hello VALUES (1, 'world');";
            db.run(sqlstr);
</script>

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
