I tried to deploy my Express.js app on Heroku so many times and I get "Application error"

Time：12-27

I wanna deploy my Expree.js "Blogging-website" project on Heroku, But after trying soo many times I'm getting "Application error" that your app has been crashed "H10". This is package.json file. I followed all the steps , please let me know if I've missed anything :

{
  "name": "ejs-challenge",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
 },
  "repository": {
    "type": "git",
    "url": "[email protected]:soniiya/Blogging-final.git"
  },
  "author": "",
  "license": "ISC",
  "engines": {
    "node": "14.17.6"
  },

And also added this in my app.js file:

app.listen(process.env.PORT || 3000, function () {
  console.log("Server started on port 3000");
});

I've created Procfile too "web: node app.js". Actually when I deployed the same app without User Authentication feature, it deployed successfully but when added authentication it's crashing now. I used MongoDB for database, If you have any suggestions then please let me know. What can cause "App crashed" on heroku?

This is the "heroku logs":

1. Try to set up this type of directory Structure

|__client/  THIS IS EVERYTHING FROM THE REACT SIDE 
    |__ node_modules/
        |__ tons of stuff...
    |__ public/
        |__ index.html
        |__ favicon.ico
        |__ etc.
    |__ src/
        |__ index.js
        |__ main/
            |__ App.js
            |__ etc.
|__ models/
    |__ user.js
    |__ todo.js
    |__ etc.
|__ node_modules/
    |__ stuff...
|__ routes
    |__ userRoutes.js
    |__ todoRoutes.js
    |__ etc.
|__ .gitignore
|__ package.json
|__ server.js
|__ etc.

2. Please Add this Middleware

// ... Other imports
const path = require("path");

// Other app.use middleware
app.use(express.static(path.join(__dirname, "client", "build")));

// Right before your app.listen(), add this:
app.get("*", (req, res) => {
  res.sendFile(path.join(__dirname, "client", "build", "index.html"));
});

app.listen(...);

3. Add a proxy to the client's package.json based on your deploy server

"proxy": "http://localhost:8000"

So, your package.json file looks like...

{
    "name": "client",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
        "axios": "^0.17.1",
        "react": "^16.2.0",
        "react-dom": "^16.2.0",
        "react-scripts": "1.0.17"
    },
    "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test --env=jsdom",
        "eject": "react-scripts eject"
    },
    "proxy": "http://localhost:8000"
}

4. Setting environment variables on the website:

A. Open your app in Heroku
B. Go to "Settings"
C. Click "Reveal Config Vars"
D. Add a new variable and click "Add". Done!
E. Your port has to look like:- process.env.PORT || 8000

Your Port looks like this:-

const port = process.env.PORT || 8000;
.
.
.
app.listen(port);

5. Set up MongoDB Atlas IP access control

Next, you'll need to whitelist your IP address so that you can access your cluster. Go to Network Access on the navigation menu, and Add IP Address. You can either Add Your Current IP Address or Allow Access from Anywhere. Confirm your choice.

For any projects deployed through Heroku, you'll have to select Allow Access from Anywhere. This is because Heroku uses Dynamic IPs. While this isn't the most secure option, it is fine for now.

6. Add this scripts start heroku-postbuild and engines

After all this, your server's package.json should look something like this: In the terminal, type node -v. It should spit out the version of Node.js you're using. add this version in the "engines": "14.17.5"

{
    "name": "mern-to-heroku",
    "version": "1.0.0",
    "main": "server.js",
    "license": "MIT",
    "dependencies": {
        "body-parser": "^1.18.2",
        "express": "^4.16.2",
        "mongoose": "^4.13.6",
        "morgan": "^1.9.0"
    },
    "scripts": {
        "start": "node server.js",
        "heroku-postbuild": "cd client && npm install --only=dev && npm install && npm run build"
    },
    "engines": {
        "node": "14.17.5"
    }
}

You should now be all set up to deploy your site through Heroku!

CodePudding user response：

The issue is your app can't find the Google Client ID.

It seems like you haven't configured your .env variables properly in Heroku. The solution is really simple.

DOTENV Approach If you've defined your .env in this manner,

MONGO_URL="xxx.....xxx"
GOOGLE_CLIENT_ID="xx......xxx"
GOOGLE_CLIENT_SECRET="xxx.....xxx"

and in your passport-setup and db-setup you are using dotenv as,

require('dotenv').config();
.
.
.
passport.use(
  new GoogleStrategy
  (
    {
      clientID : process.env.GOOGLE_CLIENT_ID,
      clientSecret : process.env.GOOGLE_CLIENT_SECRET,
      callbackURL : '/auth/google/callback'
    },
.
.
.

then, you must have declared a .env file in your project's root directory on your computer.

Your .gitignore file might have .env mentioned, as this is the standard way of doing it (You don't push env variables to public/team repositories).

The reason it works on your computer is that the app has the context of the environment variables. In Heroku since the .env file isn't present, the app doesn't know where to find them.

All you have to do is add your environment variables to Heroku. Just go to settings in Heroku Dashboard, go to the Config variables menu.

Add your env variables in the format

Restart the dyno.

This would solve your issue.
