Express.js | Node.js - Can I use a resource in a different resource?

Question

When I have two "get" resources in my node.js/express.js program, can I use the first resource in the second resource?

Example:

var express = require('express');

var app = express();

app.get('/resource1', function (req, res) {
    res.send("Hello");
}

app.get('/resource2', function (req, res) {

    // Can I use the response from resource1 here?

}

If so, how can I do that?

Answer 1

You can try to do 2 things:

1. you can make an http request from resource2 to resource1 and get the response from there.

2. The better solution in my eyes is to put resource1 logics in a "Business logics" function and call this function from the resource2 endpoint.

You can also call the actual request function of resource1 if you re-write the code to:

app.get('/resource1', resource1Func);

function resource1Func(req, res)
{
    res.send("Hello");
}

app.get('/resource2', function (req, res) {
    resource1Func(res, res);
    //some other logics
}
