Basic routing

In general, routing in Lunatic is as follows:

app.METHOD(PATH?, HANDLER)

Where:

• METHOD - HTTP method of request (GET, PUT ...)
• PATH (optional) - request path (/, /api ...)
• HANDLER - either Router or RequestHandler

Request handler

Request handler (of type RequestHandler) is a function that accepts 3 arguments:

• req: Request - incoming HTTP request
• res: Response - server HTTP response
• next: NextHandler - next RequestHandler, which can be called in the current one

Examples

Here are simple routing examples. You can add them in your Hello World app:

POST

app.post('/', (_req, res) => {
    res.status(200).json({ message: 'POST request' })
})

PUT

app.put('/', (_req, res) => {
    res.status(200).json({ message: 'PUT request' })
})

DELETE

app.delete('/', (_req, res) => {
    res.status(200).json({ message: 'DELETE request' })
})
