Follow the steps below to set up the project locally and start contributing or testing. 4 | 5 | ## Prerequisites 6 | 7 | Make sure you have the following installed on your system: 8 | 9 | - *Python 3.11.+* 10 | - *Node.js and npm* 11 | - *Git* 12 | 13 | ## Project Structure 14 | 15 | 16 | Directory structure: 17 | └── srigadaakshaykumar-stock/ 18 | ├── LICENSE 19 | ├── README.md 20 | ├── SETUP.md 21 | ├── CONTRIBUTION.md 22 | ├── CODE_OF_CONDUCT.md 23 | ├── SECURITY.md 24 | ├── package-lock.json 25 | ├── package.json 26 | ├── static.json 27 | ├── backend/ 28 | ├──app/ 29 | ├──data/ 30 | │ ├── app.py 31 | | ├── generate_csvs.py 32 | │ ├── requirements.txt 33 | │ ├── stock-prediction.ipynb 34 | │ └── tf.keras 35 | ├── public/ 36 | | ├── icon.png 37 | │ ├── index.html 38 | │ ├── manifest.json 39 | │ └── robots.txt 40 | └── src/ 41 | ├── App.css 42 | ├── App.js 43 | ├── App.test.js 44 | ├── index.css 45 | ├── index.js 46 | ├── reportWebVitals.js 47 | ├── setupTests.js 48 | └── components/ 49 | ├── About.jsx 50 | ├── AuthContext.jsx 51 | ├── BackToTopBtn.jsx 52 | ├── ContactForm.jsx 53 | ├── firebase.js 54 | ├── Footer.css 55 | ├── Footer.jsx 56 | ├── Header.jsx 57 | ├── Login.css 58 | ├── Login.js 59 | ├── Prediction.jsx 60 | ├── SentimentChart.jsx 61 | ├── SignUp.css 62 | ├── Signup.jsx 63 | ├── Stockdata.jsx 64 | ├── StockMetricCard.jsx 65 | ├── StockList.jsx 66 | └── data/ 67 | └── stockData.json 68 | 69 | 70 | 1. *Fork the repository* 71 | Fork the project to your github account 72 | 73 | 2. *Clone the repository* 74 | 75 | bash 76 | git clone https://github.com/yourusername/stock.git 77 | 78 | 79 | ## Backend Setup (Flask) 80 | 81 | Navigate to backend folder 82 | 83 | bash 84 | cd stock/backend 85 | 86 | 87 | 1. *Create a Virtual Environemnt* 88 | 89 | bash 90 | python -m venv venv 91 | source venv/bin/activate # Linux / macOS 92 | venv\Scripts\activate # Windows 93 | 94 | Note: run python --version before creating a virtual environment. The modules in requirement.txt are compatible with <=3.11 version of python. 95 | 96 | If you're using higher versions, consider creating the virtual environement in the following way: 97 | bash 98 | python -3.11 -m venv venv 99 | 100 | Visit official website of python to download version 3.11.* 101 | 102 | 2. *Install dependencies* 103 | 104 | bash 105 | pip install -r requirements.txt 106 | 107 | 3. *Start the backend server* 108 | 109 | bash 110 | python app.py 111 | 112 | ### Optional: Enable API response caching (Redis or in-memory) 113 | 114 | Set the following environment variables (e.g., in a `.env` next to `backend/app.py`): 115 | 116 | ``` 117 | CACHE_ENABLED=true 118 | REDIS_URL=redis://localhost:6379/0 119 | CACHE_TTL_STOCK=900 # seconds for stock data 120 | CACHE_TTL_PRED=3600 # seconds for prediction endpoint 121 | ``` 122 | 123 | - If Redis is reachable, it will be used. 124 | - If Redis is not reachable, the app falls back to a safe in-memory cache. 125 | - Force refresh any endpoint with `?refresh=true`. 126 | - Cache headers: the API adds `X-Cache: HIT|MISS|BYPASS` to responses. 127 | 128 | 129 | The app will be available at http://x.x.x.x:10000. (you will find the correct url in the server console) 130 | copy the server url to use in frontend 131 | make sure the app in the testing during the code editing 132 | 133 | Change the following: 134 | 135 | bash 136 | app = Flask(__name__) 137 | CORS(app, ....) 138 | 139 | 140 | to 141 | 142 | bash 143 | app = Flask(__name__) 144 | CORS(app) 145 | 146 | 147 | for testing environment 148 | 149 | ## Frontend Setup (React) 150 | 151 | *Install dependencies* 152 | 153 | bash 154 | npm install 155 | 156 | 157 | Add server url to frontend Stockdata.jsx and Predict.jsx page 158 | 159 | from 160 | 161 | bash 162 | ${process.env.REACT_APP_API_URL} 163 | 164 | 165 | to 166 | 167 | bash 168 | http://x.x.x.x:10000 169 | 170 | 171 | ## Create a .env and add the following: 172 | 173 | bash 174 | REACT_APP_FIREBASE_API_KEY="xxxx(you credentials)" 175 | REACT_APP_FIREBASE_AUTH_DOMAIN="xxxx(you credentials)" 176 | REACT_APP_FIREBASE_DATABASE_URL="xxxx(you credentials)" 177 | REACT_APP_FIREBASE_PROJECT_ID="xxxx(you credentials)" 178 | REACT_APP_FIREBASE_STORAGE_BUCKET="xxxx(you credentials)" 179 | REACT_APP_FIREBASE_MESSAGING_SENDER_ID="xxxx(you credentials)" 180 | REACT_APP_FIREBASE_APP_ID="xxxx(you credentials)" 181 | REACT_APP_FIREBASE_MEASUREMENT_ID="xxxx(you credentials)" 182 | 183 | ## How to get Firebase Credentials? 184 | 185 | 1. Go to [Firebase](https://console.firebase.google.com) Console 186 | 187 | 2. Create a Project (or use existing) 188 | 189 | - Click Add Project → enter a name (e.g., Stock Analyzer). 190 | - Configure Google Analytics (optional). 191 | - Project will take a few seconds to be ready. 192 | 193 | 3. Register a Web App 194 | 195 | - Inside your project → go to Project Overview (top-left) → Add app → choose Web ( icon). 196 | - Give your app a nickname (e.g., stock-analyzer-web). 197 | - Click Register App. 198 | 199 | 4. Get Firebase Config Object 200 | 201 | - After registering, Firebase shows you code like this: 202 | js 203 | const firebaseConfig = { 204 | apiKey: "AIzaSyDxxxxxx", 205 | authDomain: "your-project-id.firebaseapp.com", 206 | databaseURL: "https://your-project-id.firebaseio.com", 207 | projectId: "your-project-id", 208 | storageBucket: "your-project-id.appspot.com", 209 | messagingSenderId: "123456789", 210 | appId: "1:123456789:web:abcdef123456", 211 | measurementId: "G-ABC123XYZ" 212 | }; 213 | 214 | 215 | These values map 1:1 to the .env variables. 216 | 217 | 5. Copy them into .env 218 | 219 | ## Start the project 220 | 221 | bash 222 | npm start 223 | 224 | 225 | The app will be available at http://localhost:3000. -------------------------------------------------------------------------------- /src/components/ContactForm.jsx: -------------------------------------------------------------------------------- 1 | import React, { useState } from "react"; 2 | import styles from "./ContactForm.module.css"; 3 | 4 | const ContactForm = () => { 5 | const [formData, setFormData] = useState({ 6 | firstName: "", 7 | lastName: "", 8 | email: "", 9 | message: "", 10 | }); 11 | 12 | const [status, setStatus] = useState(""); 13 | const [errors, setErrors] = useState({}); 14 | 15 | const nameRegex = /^[a-zA-Z\s]*$/; 16 | const emailRegex = /^[a-zA-Z][a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; 17 | 18 | const validateField = (name, value) => { 19 | let error = ""; 20 | if ( 21 | (name === "firstName" || name === "lastName") && 22 | !nameRegex.test(value) 23 | ) { 24 | error = "Only letters and spaces are allowed."; 25 | } 26 | if (name === "email" && !emailRegex.test(value)) { 27 | error = "Please enter a valid email address."; 28 | } 29 | setErrors((prev) => ({ ...prev, [name]: error })); 30 | return error === ""; 31 | }; 32 | 33 | const handleChange = (e) => { 34 | const { name, value } = e.target; 35 | setFormData((prev) => ({ ...prev, [name]: value })); 36 | validateField(name, value); 37 | }; 38 | 39 | const validateForm = () => { 40 | let isValid = true; 41 | ["firstName", "lastName", "email"].forEach((field) => { 42 | if (!validateField(field, formData[field])) isValid = false; 43 | }); 44 | return isValid && Object.values(errors).every((e) => e === ""); 45 | }; 46 | 47 | const handleSubmit = async (e) => { 48 | e.preventDefault(); 49 | if (!validateForm()) { 50 | setStatus("Please correct the errors in the form."); 51 | return; 52 | } 53 | 54 | setStatus("Sending message..."); 55 | const payload = { 56 | access_key: process.env.REACT_APP_ACCESS_KEY, 57 | ...formData, 58 | }; 59 | 60 | try { 61 | const res = await fetch("https://api.web3forms.com/submit", { 62 | method: "POST", 63 | headers: { "Content-Type": "application/json" }, 64 | body: JSON.stringify(payload), 65 | }); 66 | 67 | const result = await res.json(); 68 | if (result.success) { 69 | setStatus("Message sent successfully!"); 70 | setFormData({ firstName: "", lastName: "", email: "", message: "" }); 71 | setErrors({}); 72 | } else { 73 | setStatus("Failed to send message.
