Azure Node.js Easy API Middleware - node.js

Question

I've got an Azure node.js app. I wanted to add 'multer' middleware, for dealing with file uploads, to only one POST easy-api.
For example, I have the file ./api/upload-files.js, which is supposed to look something like this:
module.exports = {
"post" : async (req, res, next) => {
// ...
}
};
And I can quite easily add the multer middleware to the ./app.js file, where the express app is initialized:
const multer = require('multer');
app.post('*', multer({ storage: multer.memoryStorage() }).any());
But if I don't want to add multer middleware to every post endpoint, but just to the one in ./api/upload-files.js, how do I do that?

Original comment
This is something related with the way you are instanciating the express instance in your app.
If you do not wish to use the multer middleware for some request you can just use the function you want in the request itself, avoiding to call the multer function when passing the arguments to the request method.
One example for a get endpoint:
app.get('/getrequest', (req, res, next) => {
console.log('Someone made a get request to your app');
})
One example for a post endpoint:
app.post('/postrequest', (req, res, next) => {
console.log('Someone made a POST request to your app');
})
Keep in mind that you add or remove middleware functions in express this way.
app.use('/user/:id', function (req, res, next) {
console.log('I am a middleware!')
next()
}, function (req, res, next) {
console.log('I am another function')
next()
})
Here are the docs
Edit
Could maybe this code adapt to your usecase?
app.post('*', checkUseMulter);
function checkUseMulter(req, res, next) {
if (['/mypathwithoutmulter', '/myotherpath'].includes(req.path)) {
return next();
}
return multer({ storage: multer.memoryStorage() }).any();
}
