在heroku master上推送nodejs应用

Question

I've created a server for my front end project using nodejs on the back end. after testing it successfully on my computer(localhost:3001),I wanted to deploy it on heroku.

to do so, I ran the following codes on gitbash(windows) :

1-git init
2-git add .
3-git commit -m "my 1st commit"
4-heroku create 
5-git remote -v
6-heroku rgit:remote -a blah-blah-21222
7-git push heroku master 

here's the error I stumbled upon :

! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/blah-blah-21222.git'

I even changed the last line of my codes on server.js Which initially was :

app.listen(3001,()=>{
    console.log('app is running on port 3001');
})

and switched it to :

app.listen(process.env.PORT||3001,()=>{
    console.log(`app is running on port ${process.env.PORT}`);
})

I got the same error as well and I don't feel like if this port change is the main challenge in the first place.

Do you have any idea how I can deploy this nodejs server on heroku ?

Answer 1

You should create a named app with command :

heroku create blah-blah-21222  // blah-blah-21222 is name you want (not duplicate)

When you use:

heroku create

heroku create random name for you, please sure thas name is blah-blah-21222 Try it and see any error ?
