Code Sample Best Practices

DO

// Good: Complete, runnable example
const client = new APIClient({ apiKey: process.env.API_KEY });

async function getUser(userId) {
  try {
    const user = await client.users.get(userId);
    console.log(`User: ${user.name}`);
    return user;
  } catch (error) {
    console.error(`Failed to get user: ${error.message}`);
    throw error;
  }
}

getUser('user_123');

DON'T

// Bad: Incomplete, unclear
client.users.get(id).then(u => console.log(u));

Sample Application Patterns

Retry Logic

retry_patterns:
  code_doesnt_work:
    strategy: "Test in clean environment"

  user_stuck:
    strategy: "Add more detail, screenshots"

  outdated_deps:
    strategy: "Update, add version notes"
