Using optional middleware in Express JS

Question

I would like to know how to choose between two different middleware functions, depending on the request for the endpoint. It could look something like this:

router.post("/findAvailableAgents", middleware1 || middleware2, (req, res) => {
  // endpoint body
})

Answer 1

You could use another middleware which decides whether to choose middleware1 or middleware2

const decideMiddleware = (req, res, next) => {
    if(condition) {
        return middleware1(req, res,next)
    } else {
        return middleware2(req, res,next)
    }
}

And use it in your code

router.post("/findAvailableAgents", decideMiddleware, (req, res))
