The app will allow users to track their workouts, set goals, and monitor their progress. We will use JavaScript and a few other technologies to create this app. + +## Step 1: Setting Up the Project + +First, let's set up our project. Create a new directory for your project and initialize a new Node.js project: + +```bash +mkdir fitness-app +cd fitness-app +npm init -y +``` + +Next, install the necessary dependencies: + +```bash +npm install express body-parser mongoose +``` + +## Step 2: Creating the Server + +We will use Express to create our server. Create a new file called `server.js` and add the following code: + +```javascript +const express = require('express'); +const bodyParser = require('body-parser'); +const mongoose = require('mongoose'); + +const app = express(); +const port = 3000; + +app.use(bodyParser.json()); + +mongoose.connect('mongodb://localhost/fitness-app', { useNewUrlParser: true, useUnifiedTopology: true }); + +app.listen(port, () => { + console.log(`Server is running on port ${port}`); +}); +``` + +## Step 3: Creating the User Model + +We will use Mongoose to create our user model. Create a new file called `models/User.js` and add the following code: + +```javascript +const mongoose = require('mongoose'); + +const userSchema = new mongoose.Schema({ + username: { type: String, required: true, unique: true }, + password: { type: String, required: true }, + workouts: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Workout' }] +}); + +const User = mongoose.model('User', userSchema); + +module.exports = User; +``` + +## Step 4: Creating the Workout Model + +Next, create a new file called `models/Workout.js` and add the following code: + +```javascript +const mongoose = require('mongoose'); + +const workoutSchema = new mongoose.Schema({ + user: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true }, + date: { type: Date, required: true }, + exercises: [{ + name: { type: String, required: true }, + sets: { type: Number, required: true }, + reps: { type: Number, required: true }, + weight: { type: Number, required: true } + }] +}); + +const Workout = mongoose.model('Workout', workoutSchema); + +module.exports = Workout; +``` + +## Step 5: Creating the User Routes + +Create a new file called `routes/user.js` and add the following code: + +```javascript +const express = require('express'); +const router = express.Router(); +const User = require('../models/User'); + +router.post('/register', async (req, res) => { + try { + const user = new User(req.body); + await user.save(); + res.status(201).send(user); + } catch (error) { + res.status(400).send(error); + } +}); + +router.post('/login', async (req, res) => { + try { + const user = await User.findOne({ username: req.body.username, password: req.body.password }); + if (!user) { + return res.status(401).send({ error: 'Invalid credentials' }); + } + res.send(user); + } catch (error) { + res.status(400).send(error); + } +}); + +module.exports = router; +``` + +## Step 6: Creating the Workout Routes + +Create a new file called `routes/workout.js` and add the following code: + +```javascript +const express = require('express'); +const router = express.Router(); +const Workout = require('../models/Workout'); + +router.post('/', async (req, res) => { + try { + const workout = new Workout(req.body); + await workout.save(); + res.status(201).send(workout); + } catch (error) { + res.status(400).send(error); + } +}); + +router.get('/:userId', async (req, res) => { + try { + const workouts = await Workout.find({ user: req.params.userId }); + res.send(workouts); + } catch (error) { + res.status(400).send(error); + } +}); + +module.exports = router; +``` + +## Step 7: Integrating the Routes + +Update the `server.js` file to include the user and workout routes: + +```javascript +const express = require('express'); +const bodyParser = require('body-parser'); +const mongoose = require('mongoose'); +const userRoutes = require('./routes/user'); +const workoutRoutes = require('./routes/workout'); + +const app = express(); +const port = 3000; + +app.use(bodyParser.json()); + +mongoose.connect('mongodb://localhost/fitness-app', { useNewUrlParser: true, useUnifiedTopology: true }); + +app.use('/users', userRoutes); +app.use('/workouts', workoutRoutes); + +app.listen(port, () => { + console.log(`Server is running on port ${port}`); +}); +``` + +## Step 8: Testing the API + +You can use a tool like Postman to test the API. Here are some example requests: + +- Register a new user: + - POST http://localhost:3000/users/register + - Body: `{ "username": "testuser", "password": "password123" }` + +- Login a user: + - POST http://localhost:3000/users/login + - Body: `{ "username": "testuser", "password": "password123" }` + +- Create a new workout: + - POST http://localhost:3000/workouts + - Body: `{ "user": "userId", "date": "2021-01-01", "exercises": [{ "name": "Squat", "sets": 3, "reps": 10, "weight": 100 }] }` + +- Get workouts for a user: + - GET http://localhost:3000/workouts/userId + +## Conclusion + +Congratulations! You have built a simple fitness app similar to Fitbud. You can now extend this app by adding more features such as goal tracking, progress monitoring, and more. Happy coding!
