How to upload a file in Node.js ? Error: Cannot POST /upload

Question

PROBLEM:

I click on submit in my upload.ejs and I get the error: "Cannot POST /upload"

SOLUTION:

My problem was an architectural one more than a coding problem.

I changed the structure of my project to solve the problem.

I created a new file called "upload.js" to put the router code in.

I also moved the "upload.ejs" to the root of the project.

I updated my "app.js" to take into account the new router file "upload.js".

I changed the form to use "upload.js".

CODE:

upload.js

var express = require("express");

var router = express.Router();

var flash = require("connect-flash");



var firebase = require("firebase");



var multer = require("multer");

var upload = multer({dest:"./public/images/uploads/"});



router.get("/", function(req, res, next){

    res.render("upload");

});



router.post("/", upload.single("image"), function(req, res, next){



    if (req.file){

        console.log("Uploading file...");

        var image = req.file.filename;

    }

    else {

        console.log("No file uploaded");

        var image = "noimage.jpg";

    }



    var post = {

        title: req.body.title,

        section: req.body.section,

        image: image,

    }



    var section = req.body.section.toLowerCase();



    firebase.database().ref("posts/"+section).push(post);



    req.flash("success_msg", "Post Created");

    res.redirect("/upload");





});



module.exports = router;

upload.ejs

<form enctype="multipart/form-data" method="post" action="upload">

You are POSTing to /upload url but you the route that you register is POST /users/upload. Possibly you have to move the follwing function into the routes/index.js file:

router.post("/upload", upload.single("image"), function(req, res, next){

    if (req.file){
        console.log("Uploading file...");
        var image = req.file.filename;
    }
    else {
        console.log("No file uploaded");
        var image = "noimage.jpg";
    }

    var post = {
        title: req.body.title,
        section: req.body.section,
        image: image,
    }

    var postRef = fbRef.child("posts");

    postRef.push().set(post);

    req.flash("success_msg", "Post Created")
    res.redirect("/"+ req.body.section.toLowerCase());

});
