TypeScript Best Practices

Patterns

Async/Await Pattern

Always use async/await, never callbacks or .then():

// Good
async function createTask(data: CreateTaskRequest): Promise<Task> {
  const task = await db.insert(tasks).values(data).returning();
  return task[0];
}

// Bad
function createTask(data: CreateTaskRequest): Promise<Task> {
  return db.insert(tasks).values(data).returning().then(result => result[0]);
}
