How to process all requests directed to API Gateway through one Lambda function?

Question

Amazon Web Services

I created a lambda function which has code like this:

'use strict'

const { createServer, proxy } = require('aws-serverless-express')
const express = require('express')


const app = express()

app.use(express.urlencoded({ extended: true }))
app.use(express.json())


app.get('/', (req, res) => {
  res.send('ALOHA HONUA!')
})

app.get('/products', async (req, res) => {
  res.send('Товары')
})


app.get('/categories', async (req, res) => {
  res.send('Категории')
})

module.exports.handler = (event, ctx) => {
  proxy(server, event, ctx)
}

API Gateway configured in this way:


I.e. all requests for this API lead to one function. In the logs, I see that the function is called, however, regardless of the endpoint, only the handler for get('/') is processed. If I delete it, I get a Cannot GET /.

I believe that the problem is in the configuration of the express itself, but I do not understand how to fix it.

Answer 1

In general, the aws-serverless-express package is no longer very relevant and turned out to be. It may have been configurable to make it work, but their npm page now points to a slightly different github repository.
It is enough to follow one of their examples, for example this one, and everything will work like clockwork.
It is very convenient for various kinds of knick-knacks, if you are too lazy to fool around with dockers / nginxes.
