Express VS Next in a serverless function, PROS & CONS

[rafinskipg]

Hello everyone.

This question is to help me understand what is the performance cost of, for example, using express In a serverless function VS using the standard nextjs way.

At the first sight, express API is simple, but you have to end up creating a lot of abstractions to reuse code in a large Next project. Using express would simplify the routing and some other things.

My questions are:

• what are the best practices for large projects with many API routes?
• is there any performance impact using express in serverless vs next normal API?
• any other tips ?

Example:

Express function

/api/auth/[action]

import express from 'express'

const app = express()

app.disable('x-powered-by')

app.use(passport.initialize())

app.post('/api/auth/login', async (req, res) => {
   // DO SOMETHING HERE
})

// ADD MORE ROUTES IF NEEDED, EASY 

export default app

With next

export default async (req, res) => {
  const {
    query: { action },
  } = req

  if (req.method === 'POST' && action === 'login') {
    // DO Something
  }


}
