Difficulty getting GET requests using Node droplet and remote development?

Hey guys,

I’m having difficulty making GET requests and I’m not sure if it’s my code or maybe I didn’t setup my remote development correctly. I’m using Digital Ocean Node.js droplet “This droplet is all set up with NodeJS, PM2 for process management, and nginx.”

I keep getting a 404 in POSTMAN when I do a GET request to my ip address and when I go to the browser to my ip address/api/posts it says the page can’t be found.

server.js

require('dotenv').config()
const express = require('express')
const mongoose = require('mongoose');
const path = require('path');

const app = express()

const postsApi = require('./api/postsApi');



mongoose.connect
    (process.env.DB_URI, {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }).then(() => {

        app.listen(process.env.PORT, () => {
            console.log('Listening to port 5000!')
        })

    })


//POST form handling
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

//Routing
//app.use('*', express.static(path.join(__dirname, '../public/index.html')));
app.use(express.static(path.join(__dirname, 'public')));
//app.use(express.static(path.resolve(__dirname, '../client/build')));

app.use('/api/posts', postsApi);

postsAPI

const fs = require('fs');
const path = require('path');
let express = require('express');
let router = express.Router();
const postsController = require('../controllers/postsController');
const PostService = postsController.PostService;


// routing code

// list
router.get('/allPosts', (req, res, next) => {
    PostService.list()
        .then((posts) => {
            console.log(`API: Found posts: ${posts}`);
            res.status(200);
            res.json(posts);
        }).catch((err) => {
            res.status(404);
            res.end();
        });
});




// export our router
module.exports = router;

postsController

const Post = require('../models/postSchema');



class PostService {
    //  list
    static list() {
        return Post.find({})
            .then((posts) => {
                return posts;
            });
    }
    //  findOne
    static find(id) {
        return Post.findById(id)
            .then((post) => {
                return post;
            });
    }
    //  create
    static create(obj) {
        var post = new Post(obj);
        return post.save();
    }

    //  update
    static update(id, data) {
        return Post.findById(id)
            .then((post) => {
                post.set(data);
                post.save();
                return post;
            });
    }

    //  delete
    static delete(id) {
        return Post.deleteOne({ _id: id })
            .then((obj) => {
                return obj;
            })
    }
}


module.exports.PostService = PostService;

postsSchema

const mongoose = require("mongoose");


const Schema = mongoose.Schema;
let postSchema = new Schema({
    title: { type: String, minLength: 5, required: true },
    post: { type: String, minLength: 5, required: true }
});


module.exports = mongoose.model("Post", postSchema);
