I am creating a nodejs middleware server that will handle api transactions from a frontend and relay them to various api's (internal and external). The primary goal is to hide api keys from the frontend. It can also consolidate requests that may require 2 or more endpoints, and modify data structures, thus simplifying our frontend code.

I am hoping for feedback on overall design/structure which will allow us to create a project that will be flexible as we add more apis while keeping it DRY

URLs, keys, etc. are stored in a .env file

index.js

require('dotenv').load();
const express = require('express'),
 app = express(),
 request = require("./request").request,
 bodyParser = require('body-parser');

app.use(bodyParser.json());

//returns all locations
app.get("/locations", (req, res) => 
 let URL = '...';
 request(
 method: 'get',
 url: URL,
 api: 'apiName'
 ).then((resp) => 
 res.json(resp);
 )
);

//send password reset link
app.post("/resetemail", (req, res) => 
 let URL = '...';
 let DATA = req.body;

 request(
 method: 'post',
 url: URL,
 api: 'apiName',
 data: DATA
 ).then((resp) => 
 res.json(resp);
 )
);

app.listen(3000);

request.js

module.exports.request = function (options) 

 const client = require('./' + options.api).instance;
 const handleError = require('./' + options.api).handleError;
 const onSuccess = function (response) 
 console.log('Request Successful!', response);
 return response.data;
 

 return client(options)
 .then(onSuccess)
 .catch(handleError);

apiName.js

const axios = require('axios');
const axiosInstance = axios.create(
 headers: "token": process.env.API_TOKEN ,
 baseURL: process.env.API_BASE_URL,
 timeout: 2000
);

const handleError = function (error) error.message);


module.exports = 
 instance: axiosInstance,
 handleError: handleError

I think you need to add some middle-wares that helps to run your API code after that middle-ware with proper structuring way.

I would suggest the NPM Module express-app-generator

The advantages of it include:

• Code Management in clean way.


• Structured Routing.


• Add Multiple Middle-Wares in filters array.


• Create CRUD API's with REST or CRUD Keyword.
