Heroku Error. Cannot find module 'Mongoose' - javascript

For some odd reason (i have been deployed on Heroku for around 1.5 years) my instance decided to throw a weird error regarding not finding 'mongoose' after attempting to deploy again. Everything works on my local server and my .gitignore file ignores Node Modules. This is a React.js app with Expressjs and Mongoose.
Here is my Package.json:

mongoose.connect(process.env.mongourl)
.catch(err => console.log('Mongo connection error', err));
const db = mongoose.connection;

db.once('open', () => {

module.exports = funcs;
And lastly here is the persisting error:

The error is most likely coming from the fact that you have mongoose in your "devDependencies". Try moving it to your "dependencies", then running npm install. You may run into the same issue with express and a few others under "devDependencies". Hope this helps.


It does not make any sense, but if mongoose is both in dev dependencies and in dependencies, heroku goes nuts. It can be ONLY in dependencies. After deleting it from dev dependencies, do npm install. It will work without any issues.

Error when import firebase-functions-test when testing with mocha

I am trying to setup a Firebase Cloud Functions repo to run mocha test. However, it throws the following error when I use import * as firebase from "firebase-functions-test"; or const firebase = require("firebase-functions-test")();. You can see in my code that I haven't even called the actual firebase functions yet so I think this a setup issue.
Question: What change do I need to make mocha test running for Firebase Functions testing using import syntax?
Working test code
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
});
});
Failed Test Code using require
const test = require("firebase-functions-test")();
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
test.cleanup();
});
});

Angular Fire with Universal SSR | Everything works, but the problem is while building my app [duplicate]

I'm dealing with this issue for almost two weeks now. I tried a lot of workarounds but none seems to be working. I've installed angular-fire and firebase to its latest version, tried ng add #angular/fire, configured custom webpack.config.ts, tried rolling back to every suggested previous version. None fixed this issue.
The Actual Error:

You're getting this error because you're excluding firebase dependencies with this =>
const regex = /firebase\/(app|firestore)/;
module.exports = {
// this makes sure we include node_modules and other 3rd party libraries
externals: [/node_modules/, function (context, request, callback) {
// exclude firebase products from being bundled, so they will be loaded using require() at runtime.
if (regex.test(request)) {
return callback(null, 'commonjs ' + request);
}
callback();
}],
};
Remove this
if (regex.test(request)) {
return callback(null, 'commonjs ' + request);
}
and your app will be fine.

One workaround is to install npm packages (firebase and #angular/fire) beside the dist folder and then run the deployment script.

403 error when deploying a Node.js app on Heroku

Earlier, I was getting the following error (from the Chrome console) when trying to open a Node.js app using Heroku:
Refused to load the image 'https://browser-rpg-app.herokuapp.com/favicon.ico' because it violates the following Content Security Policy directive: "default-src 'none'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.
This was accompanied by a 403. I managed to fix it by adding this line:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js 'unsafe-inline'">
Now the first error is gone, but I'm still getting a 403. I can run the app flawlessly on heroku local web, but not when I actually deploy. Here's what the log says:

As you can see, there's no helpful message or explanation, it just says forbidden. I really have no clue what the problem could be, but here's a bunch of important/relevant files:
app.js:
const express = require("express");
const configRoutes = require("./routes");
const static = express.static(__dirname + '/public');
const app = express();
app.use("/public", static);
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
const cookieParser = require("cookie-parser");
app.use(cookieParser());
configRoutes(app);
app.listen(process.env.PORT || 3000, () => {
console.log("The application is running on http://localhost:3000");
if (process && process.send) process.send({done: true});
});

},
"author": "",
"license": "ISC",
}
Procfile:
web: node app.js
In case it's relevant, here's the "/" route that Heroku calls:
const index = (req, res) => {
res.sendFile(path.join(__dirname, "..\\public\\html", "index.html"));
return;
}
And here's the constructor that sets up all the routes:
const constructorMethod = app => {
app.get("/", index);
app.get("/game", gameGet);
app.post("/game", gamePost);
app.use("*", (req, res) => {
res.status(404).json({ error: "Not found" });
});
};
Here's my file structure as well:
BrowserRPG
│ README.md
│ Procfile
| app.js
| mongoCollections.js
| mongoConnection.js
| package.json
| settings.json
│
└───data

| gamedata.js

└───html
| game.html
| index.html

└───js

└───routes
| index.js
I'm also using a mongodb database, but I don't think that's causing the problem, considering that I haven't even attempted to connect it to Heroku yet, and you don't need to have a db running to get to the first page of the app. Is there something here that might be causing the error? Thanks.

So I finally figured it out, the solution was actually annoyingly simple. In my "/" GET route, the path contains a .., which was being viewed as malicious, and therefore rejected. I changed it to this:
res.sendFile(path.join(appRoot, "public/html", "index.html"));
appRoot is a global variable that points to the root directory of the application. Hopefully this helps someone who may be having a similar issue.

Including local npm libraries

I am using the serverless framework to develop lambda functions in the aws cloud. Currently, I am running into an issue when including a library that I made. It seems the recommended way to do this is to either:
1) npm install <path/to/your/lib>
2) npm link and related commands
In the first situation, when using npm install ../libs, and include the module using const Libs = require('libs') , the package appears to install correctly (it is listed in the package.json). However, on uploading the service to aws or using sls invoke local -f my-func the following error is thrown:
{ Error: Cannot find module 'libs'

Using npm link gives similar results as well. I have a hunch that the issue has to do with the fact that I'm using babel and webpack, but I'm not sure.
Here is the contents of my webpack.config.js file:
const slsw = require("serverless-webpack");
const nodeExternals = require("webpack-node-externals");
module.exports = {
entry: slsw.lib.entries,
target: "node",
externals: [nodeExternals()],
module: {
rules: [
{
test: /\.js$/,
loader: "babel-loader",
include: __dirname,
exclude: /node_modules/
}
]
},
};
Including the individual clients, instead of the overall lib seems to have solved the above error, but now I am faced with a new error.

Why cannot i successfully deploy my nodejs app to heroku?

This is first time i deploy to heroku. The deployment itself was successful but when i open app i get an error.
Looks like a problem resides inside package.json or Procfile.
The fixing maybe obvious for you guys but i am new to heroku so don't come angry.
[EDIT] I have disabled production mode by running heroku config:set NPM_CONFIG_PRODUCTION=false but error still remains just logs has been changed
Thanks in advance for you help guys!

The problem is you cannot use better-npm-run directly in the CLI.
You need to use shell-exec and specify the command.
Check the official documentation: https://www.npmjs.com/package/better-npm-run#cli-commands
[EDIT]
Move better-npm-run to dependencies or make heroku to install devDependencies
Refer: https://devcenter.heroku.com/articles/nodejs-support#devdependencies
Heroku binds the port number dynamically so you need to use process.env.PORT to get the dynamically allocated port. Something similar to this.
Hope this helps!
