Creating issues

Creating issues manually can be time-consuming. Copilot Chat lets you create issues from natural language, and automatically fills in the title, body, labels, and other metadata based on your prompt.

Example scenario

You're working on an API service and need to add server-side validation to the createUser endpoint. Instead of drafting the issue manually, you use Copilot Chat to generate a detailed issue description that includes an example implementation of the validation middleware.

The following snippet shows the current implementation of the createUser route, before validation is added:

// Route
app.post('/users', validateCreateUser, (req, res) => {
  const { username, email } = req.body;
  // Simulate user creation
  res.status(201).json({ message: 'User created', user: { username, email } });
});

Example prompt

In octo-org/octo-repo, create an issue to add server-side validation for the createUser API endpoint. Include an example of how to validate the request body using an existing middleware pattern. Label it with "backend" and "enhancement".

Example response

When you submit the prompt, Copilot Chat generates a draft issue based on your description and includes a code snippet. You can review and edit the draft before creating the issue.

## Problem
The `createUser` API endpoint currently lacks robust server-side validation for incoming requests. To ensure data integrity and security, we should validate the request body before proceeding with user creation.

**Current API endpoint:**
// Route
app.post('/users', validateCreateUser, (req, res) => {
  const { username, email } = req.body;
  // Simulate user creation
  res.status(201).json({ message: 'User created', user: { username, email } });
});

## Proposal
- Add server-side validation for the request body using the existing middleware pattern.
- Ensure required fields (`username`, `email`) are present and valid.
- Return a 400 Bad Request response if validation fails.

**Example (middleware pattern):**
function validateCreateUser(req, res, next) {
  const { username, email } = req.body;
  if (!username || !email) {
    return res.status(400).json({ error: 'Username and email are required.' });
  }
  // Additional validation logic here
  next();
}

app.post('/users', validateCreateUser, (req, res) => {
  // ...
});

## Acceptance Criteria
- Server-side validation middleware is added to the `createUser` endpoint.
- Request body is properly validated.
- Appropriate error responses are returned for invalid requests.
