Code Samples

This section provides code samples for common operations using the JournalHub API. These samples are written in JavaScript using the fetch API, which is widely supported in modern browsers and Node.js environments.

User Authentication

Register a New User

async function registerUser(userData) {
  const response = await fetch('https://journalhub-bay.vercel.app/api/user/register', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify(userData),
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const userData = {
  fullName: 'John Doe',
  nickname: 'johnd',
  email: 'john@example.com',
  password: 'securePassword123'
};

try {
  const result = await registerUser(userData);
  console.log('User registered:', result);
} catch (error) {
  console.error('Registration failed:', error.message);
}

User Login

async function loginUser(credentials) {
  const response = await fetch('https://journalhub-bay.vercel.app/api/user/login', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify(credentials),
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const credentials = {
  email: 'john@example.com',
  password: 'securePassword123'
};

try {
  const { token } = await loginUser(credentials);
  console.log('Login successful. Token:', token);
  // Store the token securely for future API calls
} catch (error) {
  console.error('Login failed:', error.message);
}

Journal Entries

Create a New Journal Entry

async function createJournalEntry(entryData, token) {
  const response = await fetch('https://journalhub-bay.vercel.app/api/journal-entries', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${token}`,
    },
    body: JSON.stringify(entryData),
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const entryData = {
  title: 'My First Journal Entry',
  content: 'Today was an amazing day!',
  isPublic: false
};

const token = 'your_jwt_token_here';

try {
  const newEntry = await createJournalEntry(entryData, token);
  console.log('New entry created:', newEntry);
} catch (error) {
  console.error('Failed to create entry:', error.message);
}

Get User’s Journal Entries

async function getUserJournalEntries(token, page = 1, limit = 10) {
  const response = await fetch(`https://journalhub-bay.vercel.app/api/journal-entries/user?page=${page}&limit=${limit}`, {
    method: 'GET',
    headers: {
      'Authorization': `Bearer ${token}`,
    },
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const token = 'your_jwt_token_here';

try {
  const entries = await getUserJournalEntries(token);
  console.log('User journal entries:', entries);
} catch (error) {
  console.error('Failed to fetch entries:', error.message);
}

Update a Journal Entry

async function updateJournalEntry(entryId, updateData, token) {
  const response = await fetch(`https://journalhub-bay.vercel.app/api/journal-entries/${entryId}`, {
    method: 'PUT',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${token}`,
    },
    body: JSON.stringify(updateData),
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const entryId = 'entry_id_here';
const updateData = {
  title: 'Updated Title',
  content: 'This entry has been updated!',
  isPublic: true
};
const token = 'your_jwt_token_here';

try {
  const updatedEntry = await updateJournalEntry(entryId, updateData, token);
  console.log('Entry updated:', updatedEntry);
} catch (error) {
  console.error('Failed to update entry:', error.message);
}

Search Journal Entries

async function searchJournalEntries(query, token) {
  const response = await fetch(`https://journalhub-bay.vercel.app/api/search/journal-entries?q=${encodeURIComponent(query)}`, {
    method: 'GET',
    headers: {
      'Authorization': `Bearer ${token}`,
    },
  });
  
  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }
  
  return await response.json();
}

// Usage
const searchQuery = 'important';
const token = 'your_jwt_token_here';

try {
  const searchResults = await searchJournalEntries(searchQuery, token);
  console.log('Search results:', searchResults);
} catch (error) {
  console.error('Search failed:', error.message);
}
