Setting Up the Project

Establishing a new project structure is the first step toward achieving the automation goal.

Initialize the Project

A new directory needs to be created for the portfolio tracker application. This can be accomplished through the terminal or command prompt with the following commands:

mkdir coingecko-notion-template cd coingecko-notion-template

Next, initiate a new Node.js project by generating a package.json file:

npm init -y

Install Dependencies

The subsequent step involves installing the necessary dependencies that will facilitate the operations of the application:

npm install express axios @notionhq/client dotenv node-cron

Create the Project Structure

Organizing files within the project enhances maintainability and clarity. The directory structure should resemble the following:

coingecko-notion-template/ ├── src/ │ ├── services │ │ ├── notionService.js │ │ └── cryptoService.js │ ├── index.js ├── .env └── package.json

Environment Variables

To maintain security and flexibility, the next step involves creating a .env file in the root directory, which will house the following environment variables:

NOTION_API_KEY=your_notion_integration_token NOTION_DATABASE_ID=your_database_id COINGECKO_API_KEY=your_api_key PORT=3000

Setting Up Notion

Notion combines powerful organizational capabilities with a user-friendly interface. To leverage its potential for tracking cryptocurrency prices, specific steps must be followed.

Generate a Notion API Key

Activating the Notion API requires generating an API key. This can be done via the Notion Integrations portal. After successfully logging into Notion, the user needs to navigate to Notion Integrations and create a new integration, providing the necessary details. Upon creation, the API key will be available for copying and should be added to the .env file.

Create a New Database in Notion

To effectively track cryptocurrency investments, a dedicated database must be created within Notion. Users can create a new page and add a database by utilizing the /database command, selecting either “Database – Inline” or “Database – Full Page”.

Configuring the Database

It is imperative to set up specific columns within the database to align with the required data types for cryptocurrency tracking:

Initial Data Entry

It is essential to seed the database with initial data, allowing for effective tracking from the outset:

• Coin: BTC, Symbol: bitcoin, Quantity: 2
• Coin: ETH, Symbol: ethereum, Quantity: 4
• Coin: SOL, Symbol: solana, Quantity: 25

The intended database structure should appear organized and clear when viewed in Notion.

Sharing the Database with the Integration

To facilitate access to the database through the Notion integration, the database permissions must be adjusted. Users can do this by selecting the three dots in the top-right corner of the database and modifying the sharing settings, ensuring to link the created integration.

Retrieving the Database ID

The final step in setting up Notion involves retrieving the database ID. This can be done by accessing the database and copying the URL. The ID is found between notion.so/ and the first question mark (?). This value should be documented and later included in the .env file.

Step-by-Step Guide

With the project structure established and the Notion environment set, attention turns to implementing the necessary code to fetch and update cryptocurrency data.

Creating the Express Server (index.js)

Setting up the Express server requires an understanding of its basic configuration. Below is a simplified version of what the server’s setup entails:

import express from “express”; import dotenv from “dotenv”; import cron from ‘node-cron’; import { updateCryptoPrices } from “./services/notionService.js”;

dotenv.config(); const app = express(); const port = process.env.PORT || 3000;

app.get(“/”, async (req, res) => { try { await updateCryptoPrices(); res.status(200).json({ message: “Portfolio updated successfully” }); } catch (error) { console.error(“Error updating crypto prices:”, error); res.status(500).send(“Error updating crypto prices.”); } });

// Schedule the task to run every hour cron.schedule(‘0 * * * *’, async () => { try { await updateCryptoPrices(); } catch (error) { console.error(‘Error during scheduled update:’, error); } });

app.listen(port, () => { console.log(Server is running on http://localhost:$); });

This code serves the following objectives:

• Modules Initialization: Imports necessary modules for functionality.
• Environment Configuration: Utilizes dotenv to access environment variables.
• Server Setup: Initializes the Express application, establishing a fundamental GET route.
• Task Scheduling: Implements a cron job to ensure regular updates to cryptocurrency prices.
• Server Activation: Launches the server and listens for incoming requests.

Fetching Cryptocurrency Prices (cryptoService.js)

The next step involves crafting the functionality that will fetch live cryptocurrency prices from the CoinGecko API. Below is a possible implementation:

import axios from “axios”;

export const fetchCryptoPrices = async () => { const cryptoSymbols = [“bitcoin”, “ethereum”, “solana”]; const BASE_URL = “https://api.coingecko.com/api/v3”; const API_KEY = process.env.COINGECKO_API_KEY; const url = $/simple/price; const params = { ids: cryptoSymbols.join(“,”), vs_currencies: “usd”, include_market_cap: true, }; const headers = { “x-cg-demo-api-key”: API_KEY, };

try { const response = await axios.get(url, { params, headers }); return response.data; } catch (error) { console.error("Error fetching data from CoinGecko:", error); throw error; } 

};

This function encapsulates several critical processes:

• Framework Imports: Imports Axios for performing HTTP requests.
• Symbol Initialization: Specifies which cryptocurrencies will be tracked.
• Request Construction: Constructs the necessary URL and parameters to query the API.
• Error Handling: Implements graceful error management to avoid crashes.

Updating the Notion Database (notionService.js)

Integrating the fetched cryptocurrency prices into a Notion database is achieved through the following code snippet, which executes updates based on incoming data:

import { Client } from “@notionhq/client”; import { fetchCryptoPrices } from “./cryptoService.js”;

export const updateCryptoPrices = async () => { const notion = new Client({ auth: process.env.NOTION_API_KEY, });

const databaseId = process.env.NOTION_DATABASE_ID; const prices = await fetchCryptoPrices(); const defaultHoldings = { bitcoin: 2, ethereum: 4, solana: 25, }; const purchasePrices = { bitcoin: 30000, ethereum: 2000, solana: 120, }; for (const [symbol, priceData] of Object.entries(prices)) { const price = priceData.usd; const marketCap = priceData?.usd_market_cap; const quantity = defaultHoldings[symbol] || 0; const currentValue = (price * quantity).toFixed(2); const purchasePrice = purchasePrices[symbol] || 0; const purchaseValue = (purchasePrice * quantity).toFixed(2); const pAndL = (currentValue - purchaseValue).toFixed(2); const response = await notion.databases.query({ database_id: databaseId, filter: { property: "Symbol", rich_text: { equals: symbol.toUpperCase(), }, }, }); const page = response.results[0]; if (page) { await notion.pages.update({ page_id: page.id, properties: { "Current Price (USD)": { number: parseFloat(price.toFixed(2)), }, "Current Value (USD)": { number: parseFloat(currentValue), }, "Market Cap (USD)": { number: parseFloat(marketCap.toFixed(2)), }, "Quantity": { number: quantity, }, "Purchase Price (USD)": { number: parseFloat(purchasePrice.toFixed(2)), }, "Purchase Value (USD)": { number: parseFloat(purchaseValue), }, "P&L (USD)": { number: parseFloat(pAndL), }, }, }); } } 

};

This function performs several essential tasks:

• Notion Client Initialization: Creates an instance of the Notion client for API interactions.
• Data Retrieval: Fetches live prices using the previously defined fetch function.
• Default Holdings and Purchase Prices: These hardcoded values can be tailored based on personal investment strategies.
• Database Queries and Updates: The function queries the Notion database for relevant assets and updates their corresponding price and value properties as necessary.
